INTRODUCTION 1

The Bemis Industrial Products Division welcomes

you as a user of our Bemis TENSION-MASTER

II™

Taping Head. This manual explains how to install,

operate and maintain your Taping Head. All em-

ployees must read and understand all instructions in

this manual before they operate or maintain the

Taping Head(s). DO NOT OPERATE THE TAPING

HEAD WITHOUT PROPER TRAINING AND

SUPERVISION!

Although we make every effort to provide accurate

information about our equipment, some equipment

may be slightly different due to the owner’s special

requirements or recent engineering design changes.

Call our Technical Service Department at 1-800-

328-4504 if you need specific information not

included in this manual.

OPERATION

The TENSION-MASTER II™ Taping Head auto-

matically applies pressure-sensitive tape to boxes

as they are conveyed through the BEMISTAPER

(or other brand) case sealing machine. It can be

used as a top, bottom, or side sealing unit deter-

mined by how its setup. Operating procedures are

in Section 3.

Filled and closed boxes are conveyed past the

Taping Head(s). As this happens the Taping Head’s

infeed pressure roll applies and presses tape to the

front panel, then to the major flaps for the entire

length of the box. Additionally a brush presses the

tape to flat and irregular surfaces on the major flaps.

A spring loaded knife cuts the tape to the proper

length. Then the discharge pressure roller presses

the tape to the rear panel. The Taping Heads’

pressure rollers return to home position, ready for

the next case. The sealed case exits the machine.

FEATURES

The TENSION-MASTER II™ Taping Head is de-

signed for durability, quality tape application and

ease of operation. No special adjustments are re-

quired. Other special features include the following:

• Heavy-duty metal construction.

• Quick-threading slot in the front side plate.

• Sealed bearings at pressure roller and knife

arm pivots.

• One-way rotation tension roller.

• Quiet, heavy-duty rubber stops for knife and

roller arms.

• Long-wearing polyurethane pressure rollers.

• Roller arms can be locked out of the way for

easy knife blade changes.

• Automatically tapes various length boxes.

• Easy access to all functional areas.

RECEIVING AND HANDLING

When your Taping Head arrives, check the packing

list to make sure that you have received all parts and

equipment. Carefully inspect the box for damage. If

anything is damaged, notify the shipping company

immediately. If you will not be installing the Taping

Head right away, store it in a safe, dry place.

WARRANTY

The Taping Head comes with either the TENSION-

MASTER

INSTALLATION AND OPERATION 3

GENERAL

All preliminary settings and adjustments for the

TENSION-MASTER

II™ Taping Head are made at

the factory before shipment. These settings and

adjustments include the following:

• The Taping Head is set up for top, bottom, or

side sealing installation. The Taping Heads are

identical except for the pressure roll “spring

post” position. As a top sealing Taping Head, the

spring post must be in Position 1. For bottom or

side sealing, the post must be in Position 2.

Placing the post in these positions enables

uniform wipe down pressure compensating for

Taping Head position. This allows the same

extension spring to be used for all applications.

(See Figure 3.1)

• The tension roll is adjusted for proper tape

tension. Further adjustment is usually not nec-

essary. If you need to adjust tape tension, refer

to Section 4, “Tape Tension Adjustment”.

• The tape hub is adjusted for slight drag to

prevent tape roll over spin. If you need to adjust

tape hub drag, refer to Section 4, “Tape Hub

Drag Adjustment”.

• Both the pressure roll and the knife arm are set

at spring adjuster setting 1. For increased force,

refer to Section 4, “Spring Adjuster Setting”.

WARNING: Machine may start unexpectedly.

To prevent personal injury, ALWAYS turn

machine off first. Then disconnect electrical

and compressed air lines from main supplies

before installing, removing, threading or main-

taining the Taping Head.

Follow procedures as prescribed by OSHA stan-

dard 1910.47 lockout and tagout.

INSTALLATION

Upper Taping Head Installation

For top-sealing applications, some carton sealers

require either one plate spacer or four cylinder

spacers for proper Taping Head alignment. Spac-

ers are shipped with the Taping Head when required.

(See Figure 3.2)

For best performance, operate the Taping Head in

a relatively clean and dry environment. The tem-

perature range should be between 32˚ and 120˚ F.

Machine speed should not exceed 90 fpm (feet per

minute).

Boxes should be in good condition and have good

score lines. They should also be clean and dry.

Feed boxes to the Taping Head squarely, with all

flaps closed. Boxes should not be over or under

stuffed.

SAFETY CONSIDERATIONS

If you only disconnect the electrical and compressed

air power to stop the machine, you are creating an

unsafe situation which can endanger you and your

coworkers. If the machine switch is ON, the ma-

chine may start immediately when you reconnect

the power.

Follow procedures as prescribed by OSHA stan-

dard 1910.47 lockout and tagout.

disconnect machine from main electrical power

supply.

2.Disconnect compressed air line from main air

supply.

3.Mount tape roll onto tape roll hub.

NOTE: Make sure tape roll is mounted correctly.

When tape is threaded through Taping Head, the

adhesive side should touch only the three knurled

rolls.

4.Double tape over, adhesive touching adhesive,

to form a tail approximately 12 in. long. This tail

makes threading easier because the tape will

not stick to Taping Head components as you

thread the tape.

1.Switch carton sealing equipment power button

to ON position

2.Insert box squarely into infeed end of machine.

The following steps occur automatically. No opera-

tor assistance is required.

• When the box reaches the Taping Head(s), it

contacts the infeed pressure roll. The tape will

automatically be applied as the box moves

through the machine.

• Approximately 2-5/8 in. of tape is applied on the

front side of the box as it contacts and passes

the infeed pressure roll.

• Tape is then applied to the full length of the box

while the infeed pressure roll applies pressure

to seal the tape to the box.

• Tape applied to the length of the box is addition-

ally wiped down by a brush (where applicable).

The brush helps to wipe tape to surfaces that are

not flat.

• When the infeed pressure roll rides off the

backside of the box, the discharge pressure roll

starts to contact the box.

• The knife arm rides off the backside of the box

and cuts the tape.

• As the box passes the discharge pressure roll,

it wipes approximately 2-5/8 in. of tape down the

backside of the box.

• The Taping Head is now ready for the next box.

5.Thread tape over tracking roll and around back-

side of tension roll. Adhesive side of tape will be

in contact with tension roll.

6.Bring tape around front side of guide roll. Then

follow threading slot. Make sure tape contacts

backside of the knurled rolls located on the

infeed pressure roll arm assembly.

7.Thread tape between tape ramp and the tape

finger. Adhesive side of tape should touch the

finger.

8.Pull tape around the front side of the infeed

pressure roll. Double check that the adhesive

side of the tape is exposed to contact the box.

9.Cut the tape so the end is approximately at the

horizontal midpoint of the infeed pressure roll.

10.Restore compressed air and electrical power to

the machine.

You are now ready to turn on and operate the

machine.

OPERATION

Boxes are sealed automatically as they pass through

the Taping Head.

WARNING: The infeed pressure roll arm,

discharge pressure roll arm, the linkage that

connects them, and the knife arm are four

pinch points on the Taping Head. NEVER

place hands or fingers in or around pinch point

areas when the machine is operating.

WARNING: The knife is very sharp. Use ex-

treme care. Never place hands or fingers near

the blade when the machine is operating.

CLEANING

WARNING: Dust and dirt blown from machine

under pressure can impair your vision. Always

wear safety goggles or other suitable eye

protection when cleaning machine.

Remove loose dust and dirt with compressed air

and OSHA-approved air nozzle. Wipe off any re-

maining dirt with a damp rag. Use an adhesive

solvent to remove glue residue on rolls and knife

blade.

Do not wash down the Taping Head. If you must

wash down the machine, remove the Taping Head

from the machine or cover it with a plastic bag.

LUBRICATION

The Taping Head has been lubricated at the factory

during assembly. Further lubrication is not needed.

All bearings are sealed and do not require lubrica-

tion. All bushings require no lubrication.

ROLL MAINTENANCE

Perform the following periodic checks and inspec-

tions to prevent excessive wear, damage, or

downtime.

Idler Rolls

Idler rolls should spin freely. If they do not, they may

have a buildup of dirt or tape fragments between the

inner surface of the roll and the roll shaft. Remove

the roll, and gently clean the roll and the shaft with

adhesive solvent on a rag.

Pressure Rolls

Inspect pressure rolls regularly for wear. If they

become worn or cut, replace them to assure the best

possible wipe down of the tape.

MAINTENANCE AND ADJUSTMENTS 4

This section provides information for maintaining

and adjusting the TENSION-MASTER

II™ Taping

Head. The Taping Head is virtually maintenance

free but a routine maintenance check should be

performed periodically. Taping head components

that are worn excessively should be replaced as

soon as possible to prevent poor taping perfor-

mance, damage to the Taping Head, boxes and

their contents. Components that fail should be re-

placed immediately.

SAFETY CONSIDERATIONS

Some maintenance procedures will require disas-

sembly or adjustment of Taping Head(s) or machine.

If you stop the machine only by unplugging from an

outlet, you are creating an unsafe situation which

can endanger you and your coworkers. If the ma-

chine switch is ON, the machine may start

immediately when you reconnect electrical power.

WARNING: Machine may start unexpectedly.

To prevent personal injury, ALWAYS turn

machine off first. Then disconnect electrical

and compressed air lines from main supplies

before servicing the Taping Head.

Follow procedures as prescribed by OSHA stan-

dard 1910.47 lockout and tagout.

Some maintenance procedures will require clean-

ing Taping Head components with an adhesive

solvent. Some solvents will harm the skin upon

contact. Fumes from many solvents are harmful

when inhaled and explosive in the atmosphere as

well. Be careful when using a solvent.

WARNING: Use cleaning solvent in a well-

ventilated area. Avoid breathing fumes. Avoid

skin contact. Keep away from flame. Read

solvent safety information and instructions on

container label before using.

cleaning solvent. Let roll dry completely before use.

KNIFE CLEANING AND REPLACEMENT

WARNING: The knife blade is very sharp.

Use extreme care when maintaining or repair-

ing machine. Never place hands or fingers

near knife blade while machine is operating.

Cleaning the Knife

If the tape is not being cut off clean (ripping) and

straight, adhesive may have built up on the blade.

To clean the blade, use a soft cloth and adhesive

cleaning solvent. Let the blade dry completely be-

fore use. If the tape still doesn’t cut clean, the blade

is probably dull and should be replaced.

Changing Knife Blade

Change the knife blade when it becomes dull.

1.Make sure machine switch is turned off. Then

disconnect machine from main electrical power

supply.

2.Disconnect compressed air line from main air

supply.

3.Grasp the discharge pressure roll, and pivot the

discharge pressure roll arm assembly into the

Taping Head.

4. Insert a screwdriver, allen wrench, or similar tool

through the holes provided in each side plate to

hold the assembly out of the way. Make sure the

screwdriver or allen wrench will be under the

outfeed pressure roll arms to support it out of the

way. (See Figure 4.1)

5.Pivot knife guard up into Taping Head to access

knife.

6.Loosen two pan head phillips screws and two

lock washers that hold knife blade to knife mount-

ing bar.

WARNING: The knife arm assembly is a

cutting and pinch point area. Use extreme

care when replacing knife blade. Never place

hands or fingers in or around knife arm as-

sembly while machine is operating.

7.Carefully hold knife blade with your fingers; then

Springs either provide force for some components

or hold others in place. These springs include the

following:

• Extension spring for pressure arm force.

• Extension spring for knife arm force.

• Compression spring in the tension roll.

• Compression spring in the tape hub.

• Torsion spring to hold the knife guard in place.

As these springs become weak or worn, replace

them.

ADJUSTMENTS

Tape Finger Set-Up

A tape finger and a tape ramp form the tape into a

transverse “bow”. This bow stiffens the tape to hold

it against the infeed pressure roll. If bow in the tape

is not produced the tape finger may require adjust-

ment or replacement. (See Figure 4.2)

1.Make sure machine switch is turned off. Then

disconnect machine from main electrical power

supply.

2.Disconnect compressed air line from main air

supply.

3.The tape finger should protrude through the

ramp by 1/8”. If it’s straight it can be shimmed to

protrude through tape ramp. If the tape finger is

bent it should be straightened or replaced.

4.Check the finger to make sure it’s tight.

5.Restore compressed air and electrical power to

the machine.
