A method and apparatus for securing a zipper closure to polymeric film using minimal tension on the zipper closure includes providing first and second tension control loops, an eyemark detector, and a hole punch programmed to punch a hole in the zipper closure upon detection of the eyemark. The zipper closure and the film are supplied to a sealing station at the same speed, and the hole zipper closure is aligned with the eyemark on the film, to result in sealing the strip of zipper closure to the film resulting in minimal wrinkles to the resulting bag.

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.

A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.

A method for manufacturing pouches made of at least partly thermoplastic material, including the steps of superimposing at least two webs of at least partly thermoplastic material, joining the webs at adhesion regions or lines, and cutting the webs at cutting regions or lines in order to provide pouches. In a condition in which the webs are superimposed, the method further includes the step of mutually aligning the webs by causing the elongation of at least one of the two webs via the application of heat.
