Abstract (en)
[origin: WO8204011A1] Device for the manufacture of and removal by groups of synthetic material bags produced from a flat band shaped as a tubular sheet, which is displaced intermittently. A holding device is arranged behind a cutting device in the feed direction of the band. It holds each bag separate from the band in the area of its open edge. To provide such a device having a simple construction, and allowing the manufacturing of non perforated bags, the holding device is comprised of a suction box (32) provided with two rows of suction holes (33, 34) arranged in the region of the conveying plane, perpendicularly to the conveying direction. The distance between those rows corresponds approximately to that of the groups of bags arranged one on top of the other. A pressure cylinder (35), moving vertically, is capable of going down each time on the bag arranged in the last position. It cooperates with a counter pressure cylinder (37) arranged underneeth the upper side of the conveying belt (5). It is controlled so as to be lowered substantially only during the intermittent feed of the conveying belt (5).
