The present invention provides an improved belted reel which is particularly well suited for the winding of soft, bulky tissue webs and overcomes the limitations of the prior art. The belted reel is capable of providing coordinated web tension and nip control by providing the winding parent roll with two nip pointsthe first nip formed between the winding roll and the second between the winding roll and a second support drum. Preferably the drum encircled by the endless belt lies above the second support drum and the first and second nip points lie in the same vertical plane.

A slitter-winder for winding of pulp webs or corresponding webs with a thickness of at least 0.5 mm, in which the winder is a two-drum winder having two winding drums on support of which at least two pulp web rolls are wound. At least one of the winding drums is a nip acceptance winding drum (NAWD), that is a winding drum with a cover having a hardness of 40-80 Shore A and a thickness of 3-50 mm. The winding drums and a steel core or a shaft of the at least two pulp web rolls have parallel rotation axes and are in a rolling contact where the at least one winding drum is driven.

A device is for automatically introducing a reinforcing sheet into a coreless coil applicable to a coreless winding machine. The winding machine includes such a device. In particular, a device is for introducing a reinforcing paper sheet into a coreless roll being wound with a continuous strip material by a coreless winding machine. The device includes a feeding tray for paper sheets, a feeder of the paper sheets taken from the feeding tray, and an introduction member of a paper sheet loaded into a roll being wound in the winding machine.

The present invention relates to a rewinding machine equipped with a support system for the reel and the ribbon-like product.

In particular, the invention relates to a rewinding machine (1) for a ribbon-like product (N), comprising: a fixed support structure which supports an unwinding unit (SV) and a rewinding unit (RB); an independent first carrier roller (2), movable along a direction parallel to a support surface of the rewinding machine (1); a second independent carrier roller (4), movable in the opposite direction with respect to the first carrier roller (2); a third roller (3), placed between the first (2) and second (4) carrier rollers and movable integrally with the first carrier roller (2); a set of driving rollers (110) placed along a path between the unwinding unit (SV) and the rewinding unit (RB); a web (10), forming at least one loop, made of a material with an air-permeable texture, said web (10) unwinding between the second carrier roller (4), the third roller (3), and the set of driving rollers (110); one or more suction boxes (6) placed under the web (10) to retain the ribbon-like product (N).

A coilbox is provided for winding a metal strip to form a coil and for unwinding the metal strip from the coil. In order to further develop a known coilbox in such a manner that the position of the coil is known at all times, in particular during its passive transfer from the winding station to the unwinding station, at least one additional roller rotatably mounted on the frame is provided.
