Abstract
A flexible apparatus and process are disclosed for loading objects into pouches and then sealing the pouches, in which a pouch (10) having side walls (12,14) and an open mouth (18) is moved from a source (34) to a pouch opening apparatus (72) where the mouth is opened to pass an object such as a stack (20) of slippery sheets which is pushed through the mouth into the pouch while the object is resiliently engaged through the walls of the pouch by a mechanism (70, 82-110) to prevent the object from shifting during movement into or with the pouch, after which the pouch and object are moved, while still resiliently engaged, to a station (74) at which the pouch is evacuated and sealed. Changes are readily accomodated in object size, pouch size or format, or all of these.
