Abstract

Procedure for producing bags, provided with folded bottoms from a flattened tubular strip and equipped with lateral folds of a thermoplastic material, in which said strip is fed through an area where it is transversely welded in spaced positions and sectioned next to the parts welded to form a series of longitudinally arranged bag formats, one end thereof being welded, and a bag bottom folded therein, characterized in that it includes the steps of separately contacting the top and bottom parts of the fold of the band at points on each side of the band next to the welded end thereof, causing the upper and lower parts of the fold to move at a different longitudinal speed with respect to each other in order to directly form a rudely folded bottom, and release the bag, so that the procedure can be performed continuously and repetitively ae Raise speed to produce a multiplicity of bags seriously.
