Packer-filler machine

摘要

A mechanism is provided for filling a valved paper bag. Such bags are well-known in the art and include a valve which, upon filling of the bag, closes automatically to seal the contents of the bag. Following filling of the bag, it is removed and replaced with an empty bag. Heretofore this removal has been accomplished by an operator removing by hand the bag from a filling nozzle to a place for removal. Thus the operator must lift many hundreds of pounds in the course of a working day. In accordance with this invention, a bag is positioned, filled and then is ejected automatically without any lifting of a filled bag by the operator.
