The folding machine comprises; a pair of counter-rotating folding cylinders (1, 3), each provided with at least one gripping member (43) to fold a continuous web material (N) in a zigzag manner; and a cutting member (60) disposed in front of the folding cylinders to cut the zigzag folded web material and divide it into two piles (M) of folded articles. Each gripping member is a suction member which retains the web material by suction at the level of the respective folding line.

The folding machine comprises at least one folding cylinder (1, 3; 505) provided with at least one gripping member (43; 513) to mechanically grasp the web material (N) along a folding line. An electrostatic attraction member (79; 515) is associated with the gripping member (43; 513) to attract the web material towards said gripping member (43; 513).

The unwinding device comprises: a rotating element (3) with supports (13, 15) for at least two reels (B1; B2; B3); a splicing member (31, 33, 35) to join a first web material (N1) coming from an expiring reel (B1) to the initial free end (T) of a second web material (N2) wound on a new reel (B2). At least one mechanical member (21) is associated with each support (13; 15), to retain the initial free end (T) of the reel disposed on the support, to hold the initial free end until splicing of the two web materials.

The device includes a feed path for the products, along which the products move forward, divided into single packs with the interposition of at least one separator finger between one pack and the next; an oscillating support to receive packs of products and tip them onto a conveyor below; a front retaining element, which can be inserted and removed with respect to the feed path of the products to frontally retain the pile of products while the oscillating support performs an oscillation movement and deposits a pack on the conveyor below. The front retaining element is inserted in a space formed between the first and the second pack of the pile. The space is obtained by oscillating the support downwards. The oscillating support moves downwards by a first downwards angular movement and a second angular movement.

The folding machine comprises a pair of folding rollers (1, 3) rotating about axes essentially parallel to each other and defining a nip (5) through which a web material (N) to be folded passes. Disposed on each of the folding rollers are folding members (61, 61A; 63, 63A) which form folds on the web material parallel to the axis of rotation of the folding rollers. For each folding roller (1, 3) a transferring device (11, 13) is also provided to transfer packs of products folded by the folding rollers towards an unloading area (9), which comprises a plurality of separating fingers (15) movable along a closed path, from an area of engagement with the folded products to an unloading area of the folded products. Each of the transferring devices extends inside an annular groove (1G, 3G) of the respective folding roller (1, 3).
摘要:
The device comprises an essentially rigid smooth first cylinder (1) and an essentially rigid second cylinder 83), the latter having points (3P). the first and second cylinders rotate in opposite directions about respective axes of rotation (1A, 3A) and are pressed against each other, thus defining between themselves a lamination nip (5), through which said at least two layers are passed. There is also a pressure roller 87), with a surface (7A) that is less rigid than the first and second cylinders (1, 3), this roller interacting with the second cylinder and being pressed against it. The pressure roller forms with the second cylinder (3) an embossing nip (9) through which the layers (V1, V2) previously laminated in the lamination nip (5) are passed and in which they are embossed.
