REWIND SLIP CLUTCH ADJUSTMENT
You may need to adjust the rewind slip clutch if the rewind mandrel is not turning fast enough to take up the
label liner, or if the rewind mandrel torque is such that the liner is breaking. When making adjustments to
the rewind slip clutch (see Figure 36) note that the spring tension can be adjusted by adding or removing flat
washers. Sometimes it may be necessary to replace the o-ring and slip clutch disk.
To increase friction drive (rewind), add flat washers P/N 7101697, to compress or increase spring
tension, (see Figure 36). To decrease friction drive, remove flat washers P/N 7101697, to expand or
lessen spring tension, (see Figure 36). Flat washers should be added or subtracted one at a time until
proper drive is achieved. Conditions that may warrant adjustment of the rewind slip clutch are:
1. A change in applicator attitude. Example: 1. Reels up.
2. Upright and above.
2. A change in label carrier size. Example: 1. one inch (25mm) web. (Narrow)
2. 4-6 inch (101-152mm) web. (Wide)
3. A change in the manual speed of the applicator.
NOTE: Depending on the attitude of the machine, you will need to observe the response
of the rewind mandrel from the beginning of a roll, (no web liner on rewind
mandrel), to the end of the roll (a full web liner roll on the rewind mandrel). As
waste builds up on the rewind mandrel, the weight will play a roll in the way that
the rewind operates. Some further adjustments may still be necessary to
compensate for the change in load from the beginning to the end of a roll of
labels.
