The invention relates to a reel-up 3 for receiving and winding into a roll 4 a paper web W that arrives from a drying cylinder 2 in a paper making machine and which drying cylinder 2 is located upstream of the reel-up 3 and which paper web W follows a path of travel from the drying cylinder 2 to the reel-up 3. The reel-up 3 comprises a rotatably mounted reel spool 5 onto which a paper web W can be wound to create a paper roll 4 of increasing diameter and an endless flexible belt 6 mounted for rotation along a predetermined path of travel such that the flexible belt 6 forms a loop. The flexible belt 6 is positioned adjacent to the reel spool 5 to engage the paper web W against the reel spool 5 during winding. The reel-up 3 is arranged to receive the paper web W at the end of a path of travel of the paper web W which ends in a point of contact P with the flexible belt 6 where the paper web W meets the flexible belt 6 such that a wedge-shaped space WS is formed between the flexible belt 6 and the paper web W. From the point of contact P, the paper web W will be carried by the flexible belt 6 to the reel-spool 5. According to the invention, the reel-up 3 further comprises an air deflector 8 for diverting or evacuating air away from the wedge-shaped space WS formed between the flexible belt 6 and the paper web W. The invention also relates to a method of reeling a paper web.

In some implementations, a reeling device may receive material via a receiving end of a set of guiding blocks positioned around a reel. The set of guiding blocks are configured with an opening at the receiving end and with one or more inner surfaces configured to guide the material on a path around a surface of the reel. The one or more inner surfaces of the set of guiding blocks are arc-shaped to generally follow the surface of the reel. The reeling device may operate a motor that rotates the reel in a loading direction to facilitate loading the material onto the reel. The set of guiding blocks travel generally away from the surface of the reel based on the material being received and/or the motor operating in the loading direction.

Method for rolling up definite lengths of a mats in a unidirectional rolled roll, where mats are advanced one after another into a rolling mechanism in flattened out condition and released from the mechanism in rolled up condition. A rolled up mat is ejected from the rolling mechanism and caused to roll out therefrom on top of a succeeding flattened out mat which advances towards the rolling mechanism. A mat rolling station for performing the method is provided, where a ramp conveyer is provided which advances a flattened mat towards the rolling mechanism. At the rolling mechanism, bending conveyers are provided for advancing the forwardly moving mat sections into a circular bend on the ramp conveyer. A difference of surface speeds of the bending conveyers and the ramp conveyer is controllable by a signal provoked by the advance of a succeeding mat on the ramp conveyer before the rolling mechanism.

Rolling assembly for packaging web material in a roll having a base member with concave arcuate feed surface defining an upwardly-extending ramp, first intermediate member movably coupled to base member, and top member moveably coupled to at least one of base member or first intermediate member, top member having a concave arcuate pressure surface facing feed surface of base member. The base member, first intermediate member and top member collectively forming an iris with a feed space, the iris moveable between a first condition and a second condition, and configured to receive web material along the feed surface and direct the web material upwardly toward the top member to form a roll within the feed space, the iris moving toward a second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.

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.
