APPARATUS AND METHOD FOR CONTINUOUS MOTION ROTATABLE FORMING OF SOLUBLE POUCHES

摘要

A machine and method of forming multi-compartment pouches is disclosed in which two pouches formed on separate adjacent formers (1, 3) are brought together in register and the lidding webs (9, 15) of the pouches joined to form a combined pouch (33). The pouches may be held on the formers (1, 3) by vacuum until the pouches are joined whereupon the vacuum holding one of the pouches on its former (1) is released while maintaining the vacuum holding the other pouch on its former (3) so that the combined pouches (33) are held on that former by the vacuum until the vacuum is released.

1. A continuous motion machine for producing water-soluble pouches comprising two or more compartments from four water-soluble polymeric webs wherein two pouches are formed, filled and sealed on separate, adjacent donating and receiving formers, each pouch being formed from two water-soluble polymeric webs, and wherein the two such pouches are held by vacuum on their formers until they are joined together in register to form a combined pouch whereupon the vacuum in the donating former is removed releasing its pouch to the receiving former and the combined pouch still held by vacuum in the receiving former is separated from the combined web.
