Abstract

The process and apparatus serve to make bags which have an end consisting of open crossed-end folds and an end patch welded to the edges of the crossed-end folds. A tubing section is advanced in its longitudinal direction and at its leading end is pulled open and flattened to form open crossed-end folds. The end patch is moved in synchronism with the tubing section and during this movement is applied to the open crossed-end folds. The end patch is joined by seam welds to those edges of the infolded corner portions which are covered by the patch. The tubing section is then moved transversely to its longitudinal direction. The side edges of the end patch are joined by seam welds to the longitudinal edges of the open crossed-end folds.
