摘要
Thermoplastic film bag making material is processed between a hotseal jaw and cutoff knife assembly. The apparatus has complementary first and second jaws between which the material is received for sealing bag side edge areas of the bag making material. The first jaw has a groove and the second jaw has a cutoff knife for extension into the groove for separating the material into individual bags. A rubber anvil block is in a groove underlying a zipper of the bag material and the knife thrusts into the block and attains substantially straight edges in the bag cutoff. Improved end sealing of the zipper also results.
