Abstract (en)
[origin: EP0303726A1] The method is used for producing a half-tube web from which fillable and closable bags can be produced. The half-tube web consists of a material which is capable of being adhesively bonded and/or sealed. In the region of the first of the two longitudinal outer edges (8) running in the direction of feeding of the half-tube web, at least one continuous strip (17) is fitted in each case to the top side and to the underside of the half-tube web in pockets which are continuously integrally formed on the web during its feeding, before the separation and filling and subsequent closing of the bags from the open, second longitudinal outer edge which is parallel to the first longitudinal outer edge. In this method, before the strips are fitted in the pockets, parts (12) of the half-tube web are punched out at an interval corresponding to one bag width in the region of the first longitudinal outer edge. After the continuous strips have been fitted, they are then separated in the region of the punched-out part and the two separated, adjacent ends of the top side and underside are interconnected without nodes (20). <IMAGE>
