Abstract: A machine for folding, cutting, and stacking napkins is provided. The machine has a feeding station, at least one pair of folding rollers pivoting about horizontal rotational axes, a blade, and a pair of spacers having fingers configured to support the napkins stably downstream of the blade, with respect to a horizontal plane perpendicular to a direction of travel, the folding rollers being provided with circumferential slots for inserting the spacers.

Abstract: The feeding unit (10) comprises: support means (12) for rotatably supporting a first reel (R1) of two-layer tissue web and a second reel (R2) of two-layer tissue web about respective axes of rotation (x1, x2); cutting means (32, 42) for cutting the two layers (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use, the cutting means (32, 42) being configured to cut the two layers (L1_1, L2_1) of the tissue web (W1) along two cut lines spaced apart from each other in the longitudinal direction of the web (W1); joining means (44_1, 44_2) for joining each of the two layers (L1_2, L2_2) of the tissue web (W2) of the other reel (R2) of said first and second reels (R1, R2), and precisely of the new reel, to a respective layer (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use; and tissue web accumulation means (30) for accumulating a given amount of web (W1) downstream of the cutting means (32, 42) and the joining means (44_1, 44_2) so as to ensure the feeding of the machine with the tissue web (W1) wh

Abstract: An unwinding device (10) is described for unwinding rolls (12, 14) of one-ply or two-ply web-like material (24). The device (10) comprises: a support group for sustaining a first roll (12) and a second roll (14), the support group being composed of a support pin (16) for each roll (12, 14), the support pins (16) being bound on two opposite sides of a vertical column (18) made integral with the base (20) of the unwinding device (10); an unwinding mechanism (22) for each roll (12, 14), adapted to unwind the web-like material (24) from the rolls (12, 14); a joining mechanism (26), adapted to join specific web-like material portions (24) together that respectively come from the first roll (12) and from the second roll (14).

Abstract: A device (2) is described for separating and conveying towards a packaging station (5) a predetermined number of flat objects fed in piles (13. 13?) by a folding unit (1). The device (2) comprises: a conveying surface (20, 120) provided with a plurality of slots (21), a plurality of shoes or carriages (24) which support a plurality of racks (31) moveable from a lowered position to a raised position in which the prongs (32) of the racks pass through the slots (21) of the conveying surface (20, 120) to protrude upward therefrom. A predetermined number of flat objects are separated from a pile (13, 13?) being formed to form a pack (113, 113?) between a pair of racks (31) supported by a pair of carriages (24), which are made to translate so as to convey the pack (113, 113?) towards the packaging station (5).

Abstract: A method and a device for cleaning a cylinder of a printing press—in particular of a flexographic printing press—are described wherein a layer of ink to be transferred to a web substrate to be printed—such as paper, plastic film and the like—is deposited on said cylinder (1) and wherein a fluid suitable to detach impurities from the area concerned is sent onto the surface of the cylinder (1) to be cleaned and a suction is provided to remove said impurities from the cylinder surface, said cleaning fluid being vapour.
