Solution: Inspect the former. If damaged or worn, the former should be repaired.

NOTE: A badly worn former cannot be repaired. The Mira-Pak former is a highly accurate piece of equipment, and great care should be taken in handling.

Solution: Check tongue and former spacing, which should be approximately 1/16".

Solution: Check spacing between tongue and former overlap, which should be approximately 1/16".

Solution: If jaws are closing too early, the film will be pushed upward and slack will be created, thus tearing film when the jaw frame starts downward. If jaws are closing too late, the jaws will grab the film at a high speed and also tear the film. To adjust jaw close point, place hand above jaw carrier in such a manner that the carrier will touch the fingers at the very top point of the stroke and listen for the click of the jaws when they close. Adjust jaw close cam until the touch and the click synchronize. After jaw close cam is set, reset interlock #1 cam so that the trailing edge is leaving switch #1 just as the leading edge of the jaw close cam is engaging switch #5.
