Punched and incised portions can be formed properly, in which it is not necessary to replace an anvil depending on a type of a sheet material. A punching unit 51 comprises: a punching blade 50 for punching a first panel material 11, a second panel material 12, an open tape and a mounting base portion so as to form a punching portion; a incising portion 51 for incising the second panel material 12 and the mounting base portion disposed on the open tape so as to form a incising portion; and an adjusting portion 54 for adjusting a first gap 56 in a punching direction 5Z between edges 50A and 51A of the punching and incising blades 50 and 51.

A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

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.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

The present invention relates to a method and to a system for calibrating an automatic pouch forming machine. The present invention also relates to a device for characterizing a pouch precursor made of flexible heat-sealable film, said device comprising: a punch; a heat source for heating at least a tip of the punch to a given temperature; an actuator for pressing the punch against the pouch precursor made of heat-sealable film, with a given pressure; a measurement device for measuring the penetration of the punch in the pouch precursor, under the given conditions of temperature and pressure.
