At first, a semihose is made with a label fold (2) as well as a bag fold (3), whose free ends overlap with each other, whereby the free edge of the bag fold (3) is disposed on the outside. The labels 6 which are inserted in the longitudinal direction of the semihose control the forward movement of the semihose within the device in such a manner that separating weld seams (4) as well as adjacent perforations (5) are always made between successive labels (6). A sealing weld seam (7) is made after filling the bag, so as to close the bag.

A device for making and filling bags, comprising means for supplying an elongated plastic foil; means for moving and folding the plastic foil and including a mold with a mold shoulder such that the foil is pulled over the mold shoulder and forms a semi-hose with two opposing U-folds forming upper and lower edges of the bags and including a label fold and a bag fold, each having a free edge overlapping one another so that the label fold is covered from outside by the free edge of the bag fold; means for inserting labels and including a label feeding member which moves synchronously with the semihose and inserts labels into the label fold through an opening in the semihose; means for separating bags and including a separating weld die which forms separating weld seams extending behind each inserted label over a total width of the bag fold and partially into an area of the label fold so as to leave intact a partial width of the label fold; means for filling the bag folds while the bags are still connected with one another by the partial width of the label folds; and means for closing the bags and including a weld die which forms a seal weld in the region remote from a bottom of the bag fold and a top of the label fold so that the top of the label fold and the bottom of the bag fold do not have any seams.
