Embodiment Construction

[0023] figure 1 A device 100 according to the invention is shown, which may be part of a flooring device for producing bags made of hose pieces. The hose pieces 101 shown therein are successively passed transversely to their main direction of extension on a table 102 serving as a mating position or at least as part of a mating position in the transport direction z by means of a transport device not shown. The device 100 carries. The hose piece 101 has an already opened bottom 106 at its visible end. The rear wall 103 as well as the front corner deflection 104 and the rear corner deflection 105 can be seen from this base. The bottom 106 is still unpressed, so that the corner deflectors 104 and 105 still protrude slightly.

[0024] The device comprises an encircling belt 110 which is guided via deflecting rollers 111 . The deflection rollers are mounted rotatably in a frame 112 , which in turn is supported on a machine frame (not shown). The belt 110 is also deflected by me...

Abstract

The invention describes a device for securing the open bottom of a hose piece (101) consisting of at least one plastic material with at least one surrounding strap (110) which can be Guided by the deflection roller (113) and at least one additional roller, wherein the open side of the bottom can be acted upon with a surrounding belt (110), wherein the bottom can be pressed against the mating position by the surrounding belt (110). The front deflection roller (113) is spaced from the mating position.

Description

technical field [0001] The invention relates to a device for fixing the open bottom of a hose piece according to the preamble of claim 1 and an associated method according to the preamble of claim 13 . Background technique [0002] As a starting material for the plastic bag, a hose piece is often used, which is laid flat and thus comprises a front wall and a rear wall. To produce the plastic bag, one or both ends of the hose piece are now pulled up and the bottom rectangle is laid. In this case, an angular deflection is also formed, which has a triangular shape. In the bottom forming of both ends, the hose piece is usually carried transversely through the bottom forming device, in which carrying means are provided. The opening of the end is usually achieved by separating the front wall and the rear wall in the region of the end by means of a suitable separating device, in particular a suction device, which grips the front wall and the rear wall from the outside and pulls t...
