TH73241B - Open bag or double-ended bag with a closed end using a tab material. And a set of machines for closing the bag - Google Patents

Abstract

DC60 (06/09/56) This invention involves an open bag (4) consisting of a coated or uncoated polyolefin fabric that forms the base (23) tubular body part. In particular, polypropylene or HDPE ("high-density polyethylene") fabric consists of one closed area (24) and an open second (26) or bag (25) area. Two-sided closures are manufactured from open (4) bags that are filled, coated or uncoated. Closed on one side And made from polyolefin In particular, the polypropylene or HDPE fabric comprises the base body part (23). To ensure a tight and safe closure and avoid damage to the base body (23) caused by Sutures and possible contamination involved At least one end (25) of the open (4) or end (38) of the open (25) side of the bag (25) was provided. Formation by a strip of laminate material (14) folded into a V (V) or U (U) cross-section with heat-sealed legs (27) to the body section. The base (23) shaped such a pipe. This invention involves an open bag. (4) consisting primarily of coated or uncoated polyolefins that form the base body part (23) tubular shape. In particular, polypropylene or HDPE ("high-density polyethylene") fabric consists of one closed area (24) and an open second (26) or bag (25) area. Two side closures produced from an open bag (4) with a Filled, coated or uncoated Closed on one side And made from polyolefin In particular, the polypropylene or HDPE fabric comprises the base body part (23). To ensure a secure and safe closure and avoid damage to the base body (23) caused by Sutures and possible contamination involved At least one end (25) of the open (4) or end (38) of the open (25) side of the bag (25) was provided. Formation by a glazed tab (14) that has been folded into a V (V) or U (U) cross-section and has heat-sealed legs (27) to the body. The base body (23) shaped such a pipe.

Method for closing the starting material Figure Piping on one side to produce open bags (4) or for sealing filled open bags (4) that cover one side. It consists of a tube-shaped base (23) to produce a double-sided bag (25). Where the coated or uncoated tab (14) is folded to V-shaped or U-shaped in cross section And was pulled over the first open end area (24, 38) of the tube-shaped starting material or the base body section (23), where especially the side of the strip (14) facing the starting material, or The base body (23) can be provided with a coating layer (29), and as a result of pulling over the telescoping area (30) is produced where the V-shaped material strip (14) or U-shaped, inter-self supported with the first end (24, 38) of the starting material. Tube shape or base body section (23), which characterizes whether the tubular starting material or base body section (23) consists of coated or uncoated polyolefin. Especially Polypropylene fabric or HDPE and which heat energy Desirable in the form of hot gas Especially It is desirable in the form of imported hot air. Desirable has been blown Directly into the overlapping area (30), on one side of the strip (14) facing the starting material or the base body part (23) and / or onto the surface of the starting material or the base body part (23). Which facing this side of the strip material (14) and after that the strip material (14) and the starting material or the base body part (23) were simultaneously extruded in the overlap region (30) where the thermal energy conduction Took place in time Same as the pull of the strip material (14) over the first open end (24, 38) of the starting material or Tube-shaped base (23) ----------------------------------------- -------------------------------------------------- --------- 1. A method for closing the tubular starting material on one side to produce an open bag (4) or For closing filled open bags (4) that cover one side. It is attached with a tube-shaped base (23) to produce a double-sealed bag (25). Which material is coated or uncoated? The tab shape (14) has been folded into the shape. V-body or U-body in cross-section And was tensioned over the first open end (24,38) of the material Begin the shape of the tube or base body section (23) which is especially the side of the material tube (14) facing. The starting material or the base body part (23) can be prepared with a coating layer (29) and As a result of tension over the telescoping area (30) is produced where a V-shaped strip (14) or The U-itself is supported between the people itself by the first end (24,38) of the starting material, the pipe shape or the section. The base body (23) with a characteristic feature of the tube-shaped starting material or the base body (23) consists of Polyolefin coated or uncoated fabric Especially Polypropylene or HDPE fabric and thermal energy As it should be used in the form of hot gas. Especially as it should Selected in the imported hot air form. As it should be used, it has been blown. Directly into the overlapping area (30) on the side of the strip (14) facing the starting material, or The base body (23) and / or onto the surface of the starting material or the base body part (23) facing. This side of the strip (14) and after that the strip (14) and the starting material or the base body part (23) were simultaneously extruded in the overlap region (30), where the thermal energy conduction occurred in time Same as the pull of the strip material (14) over the first open end (24,38) of the starting material or Tube-shaped base (23)
