Abstract: The invention relates to an apparatus for producing a pack (20) from a packaging-material web, comprising a forming tube (2), a filling tube (11), which runs, in part, through the forming tube, a forming shoulder (3), which is arranged on the forming tube (2) and is A intended for forming a flexible enveloping tube, a folding means (7), which is arranged downstream of the forming shoulder (3), as seen in the conveying direction (A) of the flexible enveloping tube, and a sealing means (6) with a multiplicity of sealing units (6a, 6b), which are arranged downstream of the folding means (7), as seen in the conveying direction (A) of the flexible enveloping tube, wherein the forming tube (2) has a first diameter (D1) and in the filling tube (11) has a second diameter (D2) wherein the first diameter (D1) is greater than the second diameter (D2), wherein the folding means (7) is arranged at the end has first of the forming tube (2) and wherein the folding means (7) has a parabola-form folding element (8) in order t

Abstract: A method of and apparatus for producing bag packages with edge seals, in which a sheathing tube is formed from a packaging material sheeting. Before the sheathing tube is formed, sealing seams are formed in the packaging material sheeting.

Abstract: An apparatus for producing re-closable bag packages has a device for delivering and securing a portion of a closure strip on a film web. To make greater output as well as continuous operation of the apparatus possible, it is proposed that the device be equipped with a horizontally movable securing device, which tacks the portions to a moving film web.

Abstract: A bag forming, filling, and sealing machine (10) for producing bag packages (1) has a tube forming device (7) comprised of a forming shoulder (18) and a forming tube (19) connected to it. In order to permit a bag forming, filling, and sealing machine (10) of this kind to produce bag packages (1) out of a single sheet of packaging material (15), with two longitudinal seams (11, 12) and two lateral seams (13, 14), the forming tube (19) has two sections (24, 25) connected to each other. The one section (24) connected to the forming tube (19) is inclined in relation to the incoming sheet of packaging material (15) by an angle (.alpha.). In addition, an element (28) for forming the one longitudinal seam (11) is connected to the forming tube (19). The tube forming device (17) cooperates with two diametrically opposed longitudinal seam sealers (33, 34) and a lateral seam sealer (41).

Abstract: A process and apparatus for producing, filling, and sealing bags out of a tube including a molding tube and a traveling inner tube that has a nozzle attached to it, against whose base a square bottom for a bag is folded. The nozzle is moved with a grasping device at the same speed as the feed velocity of the tube and parallel to it. The grasping device is disposed on a transverse seam jaw housing, which for its part can be moved along the feed path of the tube. Using the apparatus according to the invention and the process applicable to it, square bottoms can be folded in bags during a continuous feed of the tube, which gives rise to an especially high output of the apparatus.
