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 method and a box template production system comprising a converting part which is configured for converting a fanfolded sheet material into box templates, wherein said converting is accomplished to the sheet material when a feed direction of the sheet material through the converting part of the system is along an axis having an angle towards a plane of a floor onto which the system stands, wherein said angle is between 20 and 90 degrees.

An overwrap container includes a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom connected to the side wall. An overwrap is positioned over the side wall of the base container and has a second side seam aligned longitudinally with the first side seam. Connecting elements are positioned between the side wall of the base container and the overwrap, and join the side wall of the base container and the overwrap together except in an area along the aligned first and second seams to define an uniform spacing extending continuously between the side wall and the overwrap forming an air gap there between.

In order to successively make plastic bags each of which includes panel portions, side gusset portions and a zipper portion, a web of panel material 9 is folded and folded back along longitudinal folded lines 14, 15 and 16 and longitudinal folded back lines 17 and 18 into superposed two layers having opposite side edges at each of which a folded portion is formed. The web of panel material 9 is slit along the longitudinal folded line 16 into two divided parts after being folded and folded back. The divided parts are separated and spaced from each other. In addition, the folded portions are split at positions into sprit portions and removed at the positions partially, a body of zipper material being disposed between the sprit portions.

A system for creating custom-sized cardboard blanks for folding packagings comprises a first and at least a second supply for fanfold cardboard, a control unit (e.g., microprocessor) that calculates, based on order information regarding the desired minimum dimensions of a current packaging, under predefined optimization criteria a first blank layout for folding the packaging, said blank layout comprising a leading edge and an ending edge and transverse and longitudinal crease lines dividing the blank having a desired length and width into panels, defines, based on predefined criteria, areas around the transverse crease lines and the leading and ending edges, in which no transverse folds from fanfolding the cardboard should be present, sensors communicatively coupled with said control unit that sense information indicative of a presence of transverse folds in cardboard, a cutter to cut-off the piece of cardboard from the first or the second web and form the desired blank.

A device for inserting a web of printing material into a flat-bed die-cutting and/or embossing machine includes a compensator for converting a continuous movement of the web of printing material into an iterative movement of the web of printing material. A clamping unit clamps the web of printing material, a cutting unit carries out a cross cut through the web of printing material, and an inserting unit transports the web of printing material into the flat-bed die-cutting and/or embossing machine. The device advantageously allows the web of printing material to be automatically clamped, cut and fed to the flat-bed die-cutting and/or embossing machine. As a result, no further stopping of an upstream printing press is required and the amount of waste is reduced. A manufacturing system for producing packages and a method for feeding a web of printing material are also provided.

In a method of handling a tubular carton blank, one side of an erected tubular carton blank is gripped with a gripper mounted to a pivot such that a fold line of a flap of the one side is aligned with an axis of rotation of the pivot. The gripper, and thereby the erected tubular carton blank, is then pivoted about the pivot. The flap is brought into abutting relation with an abutment during the pivoting so that the flap is progressively folded about the fold line by the abutment during the pivoting.
