Definitions
- the invention relates to a method for producing a web of contiguous bags according to the preamble of the main claim.
- a disadvantage of this known method is, on the one hand, the troublesome waste in the form of the strip which arises during further processing, and on the other hand the fact that the known method is slow.
- the invention has for its object to provide a generic method for producing a bean bag attached faster so that no additional disruptive waste.
- the method according to the invention it is thus possible to produce a continuous web in the longitudinal direction of the bag from individual bags which are connected to one another in the overlap region.
- This, for example, wound web of bags is drawn off in bags and the removed bag is sealed in the area of the overlap area.
- the sealed bag is reduced to practically the same size as the other bag and at the same time closed again at its top edge when sealing.
- the bag can either be filled from the already open side in the area of the second longitudinal outer edge, or the bag can be opened by cutting in the area of this second longitudinal outer edge and then filled. After filling, the bag can be closed by sealing parallel to the second longitudinal outer edge to form a fin base, if necessary with prior folding.
- bags are produced using this known method, the ends of which are connected to one another in the pockets, not by means of a knot, but in another way, for example by extrusion coating using a plastic drop.
- a deflection roller generally designated 5, is provided, around which the half-tube web, generally designated 7, is guided in the feed direction 6.
- This is provided on the first longitudinal outer edge 8 with an inward fold 9 to form an inner edge 21.
- the other of the two parallel to the first second longitudinal outer edge 10 runs at the open part of the semi-tubular web 7.
- the fold 9 is attached so that the top 14 of the semi-tubular web lies further inside than the bottom 15, the edge of which forms the actual longitudinal outer edge 8.
- the underside 15 protrudes from the upper side 14 and in turn forms the second longitudinal outer edge 10.
- parts 12 of the semi-tubular web 7 are punched out in a semicircle at a distance of a bag width 11 (FIG. 2) together with separate rectangular punched-outs 13 in between, so that the first longitudinal outer edge is interrupted.
- pockets 16 are formed on the upper side 14 and the underside 15 formed as a result of the fold 9, with a continuous band 17 inserted therein. so that the semi-tubular web 7 shown in FIG. 2 results, the lower pocket 16 of which projects beyond the pocket of the upper side 14 (FIG. 3).
- the strips 17 are cut off in the area of the punched-out parts 12. The two separated adjacent ends 18, 19 of the upper side 14 and the lower side 15 of the semi-tubular web 7 are then connected to one another without knots by spraying on a plastic drop 20.
- the semi-tubular web 7 is separated at the end by means of separating sealing seams 22 running transversely to the feed direction 6, forming an isolated pouch 23.
