Case sealers are workhorses in the packaging industry, because of this, the tape head components need to be maintained properly for optimal performance. We are a Loveshaw Certified Service Provider and have compiled a list of eight common maintenance items on Loveshaw tape heads that need to be checked due to wear and tear.
All maintenance issues can usually be solved by changing the blade. Be sure to inspect the blade, making sure it is free of tape debris. When replacing blade, there is a locating pin on the blade that sets the blade in proper position.
Even the slightest amount of tape on rollers impairs its performance, so be sure to check at the beginning and end of every shift change in your facility. Look for cuts and tears in the rubber, if found replace with new roller.
This roller controls tape tension and will only rotate in one direction.
The fiber washers on the tape core are an indicator of the amount of tension. There should be moderate tension.
Spin rollers to test their movement. If rollers are not spinning freely, or spinning hard, it’s an indication of tape residue inside the roller and on the spindle which the roller rests on. Use a solvent such as Goo-D-Solv-r, or something similar, for cleaning the spindle. This solvent can be squirted inside the roller to dissolve the adhesive that’s causing the roller to “stick” on the spindle.
Look for cuts and gouges in the rubber and replace if any are found.
Each Loveshaw tapehead has a tape threading diagram showing the proper path the tape should be wound around the rollers. The adhesive side of tape goes on the knurled surfaces. The back side of tape goes on the smooth surfaces. Tape should be centered on clutch roller for tape application.
The tension spring and bolt should be checked for proper alignment. The bolt can get bent and should be straightened if necessary.
