ABSTRACT:
A device for the step feeding of web material for making bags, in automatic bag-filling machines. The device comprises two opposing feeding members which are made to rotate continuously and are supported by slides running along horizontal guides, in order to move alternatively from an advanced position in which they frictionally feed and move forward a sufficient length of web material to form a bag, to a retracted position.
