Abstract
Zur Herstellung von sogenannten Hemdchenbeuteln wird eine flachliegende, beidseits mit mindestens einer Seitenfalte versehene Schlauchbahn mit die Seitenfal tenbereiche schlaufenartig zu Traggriffen schließenden Kopfschweißnähten, mit die Innenkanten der Seitenfalten erfassenden Hemdchenausschnitten und nach dem Falten um ihre Längsmittellinie auf sich selbst mit alle Lagen erfas senden Bodenschweißnähten und zwischen den Kopf- und Bodenschweißnähten mit die Beutel trennenden Querperfo rationen oder Quertrennschnitten versehen. Um in einfacher Weise die Hemdchenbeutel mit Kronenböden zu versehen, wird die Schlauchbahn vor ihrem Falten um ihre Län gsmittellinie im Bereich der späteren Kopfschweißnähte mit ein Verschweißen verhindernden, quer über die Bahn ver laufenden Trennschichtaufträgen versehen. Die Schlauch bahn wird anschließend derart gefaltet, daß die Trennschi chtaufträge aufeinanderliegen. Sodann wird die auf sich gefaltete Schlauchbahn mit den Kopf- und Bodenschw eißnähten versehen -. For the production of so-called shirt bags becomes a flat lying, bilaterally with at least one Side gusseted tube sheet with the side gusset areas that loop like handles Butt welds, with the inner edges of the gussets necklines and after folding around its longitudinal center line on itself with all layers covered send bottom welds and between the head and Bottom weld seams with cross-separating the bags rations or cross cuts. To be easier Way to provide the bottom of the shirt bags with crown bottoms, the tube sheet will fold around its length before being folded middle line in the area of the later head welds with prevent welding, across the web ver current interface orders. The hose web is then folded in such a way that the separating ski orders lie on top of each other. Then it turns on itself folded tube sheet with the head and bottom provided with seams -.
