A first feed device adjusts an intermittent feed amount thereof based on output of a first sensor such that a design position of a first panel is aligned with a first fixing position during every pause phase of an intermittent feed cycle. A second feed device adjusts tension of a second panel and an intermittent feed amount of a feed unit based on output of at least one second sensor such that a design position of the second panel is aligned with a second fixing position during every pause phase of an intermittent feed cycle. A third feed device adjusts an intermittent feed amount thereof based on output of a third sensor such that the design position of the first panel is aligned with the second fixing position during every pause phase of an intermittent feed cycle.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

The present invention relates to a method for making packages (100) made of flexible material. The method comprises a first step which consists in providing a first strip (19) and a second strip (20) made of flexible material, positioned on top of each other along a conveying direction and preferably having the same width. Moreover, the method comprises a second step of securing the first strip (19) to the second strip (20) by means of a welding surface (24) which extends in a direction perpendicular to the conveying direction of the first and the second strip (19, 20) for a first length (h4) which is less than the width (h3) of each of the first and the second strip (19, 20); wherein the welding surface (24) is positioned at a first side edge (39) of the first and the second strip (19, 20). In addition, the present invention also comprises a machine (200) which allows using such method.

Provided is a bag making apparatus with a simple configuration that: prevents fluctuations in tension, slippage of seal positions, and meandering or skewing of a web of film; allows the setting of precise initial conditions; reduces or makes unnecessary monitoring, and time and structures for adjustment; allows increased feed rate; and improves production efficiency. The bag making apparatus for packaging containers comprises: a tension control unit for controlling the continuous feed rate according to the values detected by a tension sensor of a tension detection roll; an optical detection unit for simultaneously recognizing multiple marks provided on the surface of the web of film at the respective positions thereof; a skewing correction unit; and a seal position correction unit for adjusting the positions of multiple sealing units in the feed direction.

A longitudinal method for producing a side-gusseted bag includes providing an incision extending in a transverse direction in a bag film for each side-gusseted bag in such a way that, in the case of a subsequently formed side-gusseted tube, the incision extends over both side gussets and a first front wall that is situated between the side gussets. Proceeding from the incision, the first front wall, together with the corresponding parts of the side gussets, is folded back, on which a separate film section is placed and fastened in the folded-open region. The folded-over section is folded back in such a way that all connecting seams of the separate film section extend in parallel to each other in the transverse direction.

First and second panel webs are superposed on each other and fed in their longitudinal direction. After a side gusset is temporarily fixed to the second panel web, the side gusset is divided by a dividing device to form a pair of open edges. The open edges are aligned with a line of weakness of the first panel web when the first and second panel webs are superposed on each other. The side gusset is temporarily sealed to the first and second panel webs by a temporary seal device to form temporary sealed sections. The first panel web is guided to be divided along its line of weakness and to be folded on the sides of its division edges. This guiding of the panel web and the temporary sealed sections cause the side gusset to be opened at the open edges to form open surfaces. An end face web is then disposed on the panel web to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

The present disclosure relates to the simultaneous manufacture of reclosable packages or pouches by application of a closure or reclosure onto a package web or film in the transverse direction. The web or film is folded along a machine-direction centerline so that one half of the web or film overlies, or is coextensively aligned with, the other half of the web or film. Heat seals and slits are formed in the machine direction, thereby forming the side seals of the plurality of reclosable packages or pouches.

The spout-equipped container includes a container and a spout. The spout includes a spout main body, an opening body accommodated in a cylinder of the spout main body, an activating body which moves the opening body, and a hermetically-sealing sheet which covers an inner opening which fronts an accommodating unit in the spout main body. The opening body is formed so as not to be get out of the spout main body, is formed so as to move toward the hermetically-sealing sheet, and has its center where a spout through hole is formed. The hermetically-sealing sheet is formed so as to be partially torn by the opening body to make the accommodating unit of the container and an outer opening of the spout main body communicate with outside via the spout through hole of the opening body, and is formed so that an accommodated substance is poured outside.
