摘要： A machine (1) for producing packages of napkins, tissues, towels, or similar products, comprises a support frame (100) to support a feeding group (10) which feeds a first and a second web of paper (5a, 5b). The support frame (100) supports, furthermore, a cutting group (20) which cuts the first and second webs of paper (5a, 5b) respectively in a first and a second plurality of sheets (6) of predetermined length, and a folding or interfolding group (30) which folds or interfolds the sheets of paper (6) at a folding or interfolding zone, (35) in such a way to obtain a stack (150) of folded or interfolded sheets, according to a predetermined folding or interfolding configuration. The cutting group (20) and the folding or interfolding group (30) are mounted on the same support body (110) to move between an assembled position in which is supported by the support frame (100), and a disassembled position, in which is not supported by the support frame (100). A displacement group (50) is, furthermore, provided to displace the support body (110) between the assembled position and the disassembled position. The displacement group (50) and the support body (110) are provided with respective engagement portions (58,118) to engage with each other in such a way to allow the displacement group (50) to displace the support body (110) between the assembled position and the disassembled position

摘要： A machine to produce stacks of folded pop-up wipes from material that is threaded along a path having a direction through the machine. The machine includes a holder, a first tension unit, a perforation unit to generate perforations in the material in a direction orthogonal to the direction of the path, and a folding unit to fold the material in a direction orthogonal to the direction of the path. The material is threaded along a path through the machine via the first tension unit, the perforation unit and the folding unit. A control unit controls the machine to produce folded pop-up wipes by individually controlling tension of material along one or more sections of the path and to increase tension of the material in a section of the path located after the perforation unit to stretch a generated perforation in the section of the path by a target distance.

摘要： The present invention relates to a device (20) for winding a longitudinally cut material web having multiple longitudinal strips (12) on a plurality of winding tubes (16) to form in each case a wound roll. The device comprises an axle (24) and, mounted on the axle, a plurality of ring-shaped winding drives (22) that are individually controllable in their operating position. Each winding drive (22) forms an external-rotor electric motor and comprises a static interior tube (40) and a rotatable external tube (50). The external tube (50) that is rotatable on the rolling bearings (48) bears, on its interior, a device for providing an excitation magnetic field (52) that forms the external rotor of the electric motor.

摘要： A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.
