A method is disclosed for forming a windowed packaging material. According to the method a web of packaging material is cut in substantially the machine direction along a non-linear path. The cutting action provides two subwebs, each having protruding edge portions and recessed edge portions. The two subwebs are displaced relative to one another so that the protruding edge portions face one another. In this configuration opposing recessed edge portions form windows. The two subwebs are adhered to one another at the opposing protruding edge portions. The resulting windows may be covered with a material that is transparent and/or breathable. A strip of handle material may be applied spanning the respective windows.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

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.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

A device for making tobacco pouches from a film includes a first folding station for receiving the film and providing a bottom fold in the film; a buffer station for buffering a length of film having the bottom fold; a second folding station for receiving the film having the bottom fold from the buffer station and providing a first fold; a second fold and a third fold in the film for defining the block-bottom, the first fold and third fold having a same fold direction and the second fold being located between the first and third fold and having a counter fold direction, where the first folding station is provided upstream of the buffer station and the second folding station is provided downstream from the buffer station.

The present invention relates to a method for manufacturing a packaging container having an inlay, said method comprising the steps of: arranging a first layer of packaging material and a second layer of packaging material to form a packaging container; positioning an inlay between the first and second layers of packaging material; joining at least a first region of the inlay to the first layer of packaging material; manufacturing a packaging container by joining the first and second layers of packaging material such that a filling opening of the packaging container is formed between the second region of the inlay and the second layer of packaging material; and joining at least a second region of the inlay to the second layer of packaging material of the filled packaging container. The invention also relates to an insertion device and to a packaging machine.

An apparatus 10) and a method for manufacturing plastic bags (20) from at least two layers of plastic film (30, 40). The apparatus (10) comprises a lower tool plate (300) and an upper tool plate (400); the lower tool plate (300) is driven by a crank (650) on a servomotor (675). The servomotor (675) is connected to a measuring device (680) for measuring the power consumption.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

A method for producing a bag from a tube including transverse lines of perforations delimiting tabs of the future bag, a rear tab of a first bag being opposite a front tab of the second bag following the first. A first step involves separating the first and second bags; a second step involves separating a piece of waste remaining on one of the bags between the two tabs. The first and second steps are carried out between a first pair of separation cylinders and a second pair of cylinders, the piece of waste being clamped between the cylinders of the first pair during the first step in order to be held on the second bag, then clamped and torn off by the second pair during the second step.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.
