A folding machine folding a sheet P1 into a predetermined folding pattern to form a signature P3, a saddle stitching machine 3 arranged downstream of the folding machine to staple and fold the signature and a control unit 15 controlling the folding machine and saddle stitching machine are provided. The folding machine has parameters adjustable depending on a thickness of the sheet. The saddle stitching machine has parameters adjustable depending on a thickness of the signature P3, P4. The control unit sets the parameters of the folding machine based on the information about the thickness of the sheet and sets the parameters of the saddle stitching machine based on the information about the thickness of the signature calculated using the information about the thickness of the sheet and the information about the folding pattern of the folding machine.

Embodiments of the present invention provide new and improved folding apparatuses and methods for interfolding a continuous stream of sheets into a single-fold interfolded pattern of sheets while passing all of the sheets substantially along a single sheet path. More particularly, all sheets in the continuous stream of sheets pass through the nips between adjacent components.

The present invention refers to a sheetlike composite, comprising as a layer sequence in a direction from an outer surface of the sheetlike composite to an inner surface of the sheetlike composite a) an outer polymer layer, b) a colour application, c) a carrier layer, and d) a barrier layer; wherein the sheetlike composite comprises at least one longitudinal crease line; wherein the at least one longitudinal crease line is oriented in a first direction; wherein the sheetlike composite has a first bending resistance in the first direction; wherein a further direction is perpendicular to the first direction; wherein the sheetlike composite has a further bending resistance in the further direction; wherein the first bending resistance is less than the further bending resistance. The invention further refers to a container precursor and to a closed container, in each case comprising the preceding sheetlike composite; and to a container precursor and a closed container, in each case having a sheetlike composite with a first bending resistance along a first direction which is less than a further bending resistance along a further direction.

Provided are a device for producing a disposable wearable article and a method for producing a disposable wearable article capable of suppressing the occurrence of a sealing failure by making it difficult for a doubled sheet to open against an elastic force of an absorber. A device for producing a disposable wearable article includes a jointing/cutting unit (60) provided in a line (L1) for continuously conveying a sheet (W) and configured to join parts of the doubled sheet (W) at opposite sides of an absorber (C) and then cut the joined parts and a pressing unit (70) arranged upstream of the jointing/cutting unit (60) in a conveying direction (a). The pressing unit (70) includes a pressing mechanism (71, 72) configured to press the sheet (W) together with the absorber (C) in a thickness direction.

An assembly for folding polymeric film for machines for forming pouches and the like includes a fixed frame for supporting a magazine for the polymeric film, an element for folding the film that arrives from the magazine, and at least one heat-sealing device for the stable coupling of juxtaposed portions of the folded film that arrives from the folding element. The folding element is mounted on a carriage, which can translate along a respective guide which is integral with the frame, along the sliding direction of the film, with a speed that is variable in intensity and sign. The at least one heat-sealing device acts on portions folded onto themselves of the film during a temporary stop thereof. The carriage retracts with respect to the sliding direction of the film for the entire duration of the temporary stop step provided for the heat-sealing of the film.

An improved imbricating method, folding method, and device for producing imbricated streams (3) which are produced from singulated and preferably folded blanks (2) is provided. The method includes taking imbricated bundles of blanks including of a number of overlapping blanks corresponding to the number of the individual streams formed by the blanks of a first individual stream being transported at a distance from one another along a transport surface through a compiling station. In the process, the blanks of the at least one remaining individual stream are first of all deflected vertically with respect to the transport surface by a deflecting device of the compiling station and are then guided in the direction of the first individual stream and are subsequently deposited with an offset onto the blanks of the first individual stream.
