A method and a device are specified for depositing a flexible material web, wherein the material web (2) is supplied by means of a supply means and deposited in a zigzag shape at a depositing location (2) by means of a laying means, wherein the material web (2) after exiting from the supply means is contacted by at least two engagement elements (5, 6), which can be moved at least in opposite laying directions (A, B), of the laying means and is guided to the depositing location (2). The engagement elements (5, 6) change their position during the contact with the material web (1) between an engagement position (E) and a release position (F), the quality of the deposited material web remaining largely unaffected, because each engagement element (5, 6) has a contact section (7, 8), which can be brought into a contact position (K) in the engagement position (E) and into an idle position (L) in the release position (F), wherein the movement direction (C, D) of the contact section (7, 8) is oriented at a downward angle to the laying direction (A, B).

A sheet processing apparatus includes: an output unit that renders one side of a sheet convex and outputs the sheet, the sheet having the one side and other side; a first folding unit that mountain-folds the one side of the sheet, which is rendered to be convex, to form a first fold in the sheet; and a second folding unit that mountain-folds the one side of the sheet, which includes the first fold formed therein, to form a second fold in the sheet.

A process for the production of books (22) with digital printing from signatures, in which the book comprises signature groups (33), each formed with basic sheets (34), are parts of respective signature sheets (42). The process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for cutting transversally the signatures sheets, and transversal and longitudinal folding equipment (46) for the formation of respective signatures (48). For a book with at least a sheet section devoid of text and/or figures in a last signature group, the method provides: a) identify a reduced signature group (59) including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip (23) to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment (46) limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment (46) for a single sheet section; and d) actuate the longitudinal folding equipment (47) for folding longitudinally the reduced signature group.

A system for stacking a fanfolded continuous web of sheet material of indefinite length, such as corrugated cardboard, includes a feeding device that guides the continuous web longitudinally, a creasing device downstream of the feeding device to form transverse creases on the continuous web with a constant longitudinal pitch to define a succession of adjacent partitions, a folding device downstream of the creasing device for progressively and alternately fanfolding adjacent partitions along the creases, and a collection device for collecting the folded web. The collection device includes a vertical column for retaining the stack of fanfolded adjacent partitions, and a cutting unit is mounted at the top of the column to act on the fly on the top adjacent partition of the stack while tracking stack-formation without stopping the folding device. A method of stacking a sheet material, such as a fanfolded continuous web of corrugated cardboard of indefinite length.

A folding apparatus includes a pair of clamping parts facing each other with the terrace therebetween, and a folding mechanism disposed outside the pair of clamping parts to fold the terrace. Each of the clamping parts includes: a body, a first protrusion, and a second protrusion. The body rotates around a rotary shaft parallel to the terrace. The first protrusion protrudes from one side portion of the body and clamps the terrace, and the second protrusion protrudesing from the other side portion of the body. When the body rotates, the second protrusion clamps an inner portion of the terrace closer to a center region of the pouch type battery cell than the first protrusion does.
