  • Page 2 Part and Instruction Manual Loveshaw Pressure Sensitive Tape Cartridge CAC60 series – 2” wide tape CAC61 series – 3” wide tape This is a combined manual for the CAC60 series – 2” wide tape and the CAC61 series – 3” wide tape. Take care when ordering parts. Make sure it is for the correct width cartridge.
  • Page 3 Theory of Operation: (Standard) Pressure sensitive tape is applied to the corrugated box as it passes by the cartridge. The box will contact the front arm roller which has pressure sensitive tape adhesive side facing outward towards the oncoming box. The front leading side of the box will contact the front roller arm and the tape will adhere to the box.
  • Page 4 Theory of Operation: (High Speed) Pressure sensitive tape is applied to the corrugated box as it passes by the cartridge. The box will contact the front arm roller which has pressure sensitive tape adhesive side facing outward towards the oncoming box. The front leading side of the box will contact the front roller arm and the tape will adhere to the box.
  • Page 5 Theory of Operation: (Pneumatic Cartridge) Pressure sensitive tape is applied to the corrugated box as it passes by the cartridge. The box will contact the front arm roller which has pressure sensitive tape adhesive side facing outward towards the oncoming box. The front leading side of the box will contact the front roller arm and the tape will adhere to the box.

    no required adjustments. However in some cases it may be necessary to adjust tape tensions. The cartridge will operate at speeds up to 170 feet/minute. Important Safety Notices: Before installing operating or servicing the tape cartridges read carefully and understand the following precautions: ...

  • Page 7: Tape Threading

    Tape Threading: The first step is to place the tape roll, on the cartridge exspandable tape core. The tape core diameter is adjustable by turning the adjustor nut. Turning the adjustor nut c.w. the core diameter increases and turning it c.c.w. the tape core diameter decreases.

  • Page 9 The tape is then threaded between the black knurled roll and the tape guide plate. The adhesive side of the tape will contact the two tape guide rollers as it is pulled through the guide plate assembly until it is at rest on the front arm roller.
  • Page 10 Adjustments:  Aligning tape : Aligning tape side to side with in the cartridge frame is done by changing the position of the tape core. This is done by first loosening the tape core locking screw with a 3mm hex key. Turn the tape core locking screw counter clockwise allowing for the desired amount of adjustment to be made.
  • Page 11  Setting tape core drag: The tape core drag setting is factory set to not allow a full roll of tape to free wheel as tape is being pulled off it. The drag setting may need to be adjusted if the tape cartridge is being operated at high speed or if the tape adhesive is causing the roll to over rotate as the tape it is being pulled of the roll.

Figure 8 Main spring  Weakest  setting  Strongest  setting  Booster  spring  Main spring tension  adjustment  Booster  adjustment   Setting booster spring compression The booster spring aids in rear tab wipe. The booster spring preloads the wipe roller arm so when the trailing edge of the box releases the wipe roller the arm can travel out at a higher rate of speed and contact the rear tab and secure it to the back panel of the box.
  • Page 13 retracted. The booster setting is adjusted stronger when the cartridge is operated at higher application speeds. Refer to figure 8.  Setting the rear tab cut adjustor: The rear tab cut adjustor is factory set to operate at 60 to 80ft/min belt speed.
  • Page 14 necessary to adjust the stop depending on the type of machine that the cartridge is being used in. If the cartridge is placed in a machine and the tape is not being applied to the major flaps with enough pressure an adjustment will be necessary.

  • Page 15: Maintenance

    Maintenance:  Application / Wipe roller replacement: Roller replacement is a tool less procedure. Simply push down on retaining pin and slide roller off the shaft. Install new roller by lining the angular pin notch on the undercut side of the roller with the retaining pin. Then push the roller onto the shaft all the way until the retaining pin protrudes through other side of the roller and extends out to hold the roller in place.
  • Page 16 rotate the knife guard back until the knife blade is fully exposed. While holding the knife guard open slowly release the front roller arm and allow it to extend outward. This will allow the knife guard locking mechanism to hold the knife guard open for easy blade replacement. The knife blades have open slots to allow for easy slide on / off replacements.
