    摘要： A process is for manufacturing bags and a bag forming web. A bag is produced therefrom. The process includes conveying a continuous printed web including printed features along a conveying direction. The continuous printed web is cut into printed web sections along the conveying direction, and at least two of the printed web sections include(s) portion(s) of the printed features. The printed web sections are spaced-apart and a second continuous web is inserted between adjacent ones of the spaced-apart printed web sections, while an alignment between the printed web sections including printed features is maintained one relative to the other, along the conveying direction. The second continuous web is secured to the adjacent and spaced-apart printed web sections along longitudinal adjacent edges, thus forming a combined continuous bag forming web. Bags are formed from the combined continuous bag forming web, and the features on the different printed sections of the bags are in alignment.

    摘要： 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.

    摘要： An apparatus successively makes plastic bags each of which includes an end surface provided with a protrusion, without specially supplying a web of bottom gusset material. A first web of panel material is folded along a first folded line at a position adjacent to a side edge of the first web, while a second web of panel material is folded along a second folded line at a position adjacent to a corresponding side edge of the second web. A first folded portion is formed in the first web. There exists a distance between the side edge and the first folded line, which is larger than twice a distance between the corresponding side edge and the second folded line by a predetermined distance, after being folded. The end surface is formed by the first folded portion, the protrusion being formed by the predetermined distance.

    摘要： 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.

    摘要： 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.

    摘要： 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.
