Abstract: Handle-forming machine for shaping and attaching strap handles to bags or carrier bags, and/or to continuous rolls of paper to make bags or carrier bags, said strap handles being formed by folding substantially into a U shape at least one strip or strap. The handle-forming machine comprises at least one carousel rotating around a main shaft, said carousel in turn comprising one or more cradles for gripping and folding the straps. Advantageously each cradle rotates around a main shaft at least from a feed station of said strap/s, to a folding station into a U shape of each strap and to a loading station of the folded strap, for attachment to the bag or to the continuous roll of paper which the bag will be made from. Moreover the cradle also rotates around its own axis radial to the main shaft, to rotate the position of the relative strap between the folding and loading feed stations.

Abstract: Systems, devices, and methods are described for providing a bag having an internally reinforced header. A reinforcing material is combined with a bag material to provide strength to the reinforced header.

Abstract: The invention concerns a rotary type bag manufacturing machine which feeds continuously material paper (R) to form angulated bottom bags (B) with handles (T) in which a top edge (S2) with the handles (T) pasted can be folded toward an inside in the manufacturing process. Material paper (R) wound in a roll is continuously fed out.

Then, a cutting device (6) cuts off the material paper (R) on a cut line aligned with the lateral slits (15) to thereby form the material paper (R) with the handles (T) which remains unfolded in a plane. A cut end portion (S2) with each handle (T) pasted is folded toward an inside to invisibly cover each reinforcing paper (T1) for the handle (T). Thereafter, angulated bottom paper bags (B) are formed through a paper tube forming process and a bottom folding process.

Abstract: For the production of loop handle shopping bags based on semi-tube sheeting consisting of thermoplastic plastic, an edge strip of the semi-tube sheeting is folded onto itself and reinforcement warps, consisting of a weld-friendly thermoplastic plastic that provides a good weld, are attached on the interior sides of the edge areas by means of glueing or welding at a distance corresponding to the width of the shopping bags to be produced. Subsequently, the edge strip is folded back so that the added reinforcement warps are positioned back-to-back. Double-layer handle strips are positioned in a U-shape and placed between the reinforcement warps with their end areas of the free shanks, and welded together with the edge areas through the reinforcement warps between welding devices. The shopping bags are then separated from the semi-tube sheeting by means of separating weld seams.

Abstract: The process for manufacturing an integrally-formed handle for a bag includes the steps of turning an edge of a sheet of bag stock on itself a predetermined number of times to form a multiple-thickness handle on the sheet stock, while leaving an adjacent portion of the sheet stock unfolded. The opposed side edge portions of the handle are then folded onto and overlying the unfolded portion of the sheet stock. The folded side edge portions are then glued onto the unfolded portion of the sheet stock. The central portion of the handle is then severed from the unfolded portion of the sheet stock. The unfolded portion of the sheet stock is then folded and glued into a bag enclosure with the handle residing adjacent a side of the bag defining a top opening.

Abstract: A process for producing paper bags with handles glued to the insides of the facing opening edges, includes perforating a paper web with transverse perforation lines spaced at distances corresponding to the section lengths necessary to produce the bags. At a given distance from the transverse perforation lines the handles are glued in adjacent pairs to the web in such a way that the outer handle parts project beyond the transverse perforation lines.
