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 process for making a container includes the step of providing at least one of a slider, sticker, textured surface, pattern, or embossed surface along a folded web of thermoplastic material that comprises a plurality of container templates. The process also includes the step of picking up, with a turner, each container template. The turner includes one or more rotator assemblies that include a rotatable shaft and a bag-contacting surface connected to an end of the rotatable shaft. The bag-contacting surface is configured to engage a top exterior side of each container template. Additionally, the process includes the step of reorienting, with the turner, each container template. The rotatable shaft is configured to horizontally translate and rotate each container template.

The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2-ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.

In an apparatus and method for successively making plastic bags, webs of first and second panel materials are superposed and fed longitudinally. A plastic film is slit to form longitudinal slit lines so as to be divided into the web of the first panel material and a plurality of webs of a bottom gusset material before the webs of the first and second panel materials are superposed. Then, the webs of the bottom gusset material are guided and supplied to the webs of the first or second panel material by bottom gusset material guide devices. The bottom gusset material is not supplied from another supply roll, and a pattern discrepancy is not caused.

A multi-function zipper inspection machine, comprising: an unwinding, a pull-out roller, an first variable frequency motor A, a first swing roller, a first conveying roller A, a dotted hole punching device, a lateral up zipper device, a heat sealing device, a cooling device, a color mark detecting device, a second conveying roller B, a second swing roller, a winder, a second variable frequency motor B; a first potentiometer A and a second potentiometer B are respectively provided above the first swing roller and the second swing roller to transmit up and down swing amplitude data of the first swing roller and the second swing roller respectively to the first variable frequency motor A and the second variable frequency motor B, so as to control speeds of the unwinding and the winding respectively.

A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.

A controller for a pouch-making machine for manufacturing a pouch while feeding a pair of film materials each provided with a reference mark that indicates a reference position for layering the film materials together, includes a driven roller shift unit for independently shifting each shaft of a pair of driven rollers that rotate being driven by the pair of film materials being fed and a control unit for controlling the driven roller shift unit based on a result of an image-shooting unit shooting images of the reference marks, so that positions of the reference marks provided on the pair of film materials coincide.

A method and apparatus for accurately performing multiple tasks on a web of material are described herein. The method and apparatus include at least a first detector for detecting a detectable feature on the web of material for performing a first operation at a first location on the web of material, and a second detector for detecting a detectable feature on the web of material for performing a second operation at a second location on the web of material. The method and apparatus further include an automated compensating device that cooperates at least indirectly with the detectors. The compensating device reduces any variations in position along the length of the web of material between at least one of said first locations and/or said second locations.
