An assembly for handling reel spools, comprising linear support rails, having a first end and a second end, arranged parallel to each other, and a reel spool cart arranged on the support rails, the support rails being arranged at a first distance from each other, the first distance being greater than axial length of the reel spool, and the cart being provided with a hoisting device configured to hoist the reel spool vertically from beneath of at least one of the support rails to at least partly above at least one of the support rails.

The machine (1) comprises an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N), an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one winding station (15). The winding station in turn comprises a winding device (41, 51), to which a longitudinal strip (S) of web material is fed. In the winding station, a respective spool (B) of web material is formed. The winding station (15) further comprises: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversally, thus forming a tail edge, which remains on the spool (B) under formation, and a leading edge; and a holding device (85) for holding the leading edge of the longitudinal strip (S), to transfer the leading edge onto a tubular winding core (T) of a new spool to be wound.

A holding and supporting group of a winding spindle in a machine for winding plastic film onto spools includes a winding reel positioned between two uprights, wherein a first upright carries a rotating plate which cantilever-supports three spindles and a central shaft, wherein the central shaft is supported at the other end by the second upright, wherein, in correspondence with a free end of the central shaft, there is a star-shaped plate with three supporting arms for each free end of the three spindles through a respective toggle lever mechanism driven by an actuator carried on a lever articulated with respect to the star-shaped plate, and in turn caused to oscillate between an operative blocking position of the respective spindle and a rest position for releasing the respective spindle by an additional actuator.

Techniques for processing a web with a laser are provided. In an example, an apparatus for processing web material can include multiple processing stages and a laser assembly. Each of the multiple processing stages can be configured to process a moving web of material along a web path. The laser assembly can be configured to process the moving web of material with a laser at a first stage of the multiple stages. The laser assembly can include a laser configured to generate a laser beam, a gimble assembly configured to direct the laser beam along a cut path at a position of a web path of the moving web of material, and a servo driven mirror assembly configured to provide an adjustable field of view for the laser stage at the position of the web path.

The invention pertains to the field of industrial machinery for converting paper and/or for processing strip materials, and relates to a paper mill rewinder for forming reels of paper strip material, in particular, but not exclusively, tissue paper, of conventional or structured type, non-woven, TAD (Through Air Drying), or other similar materials characterized by having a very light weight and low density, with continuous, or non-stop, reel change device. Said rewinder (1) comprises: a supporting frame (3); feed means (4) for a winding rod (A); a main forming cradle (C1) for a reel (B) around said winding rod (A), comprising a first (5) and a second (6) winding roller; means for unloading (7) said reel (B) once formed; a control unit, a secondary pre-forming cradle (C2) for said reel (B), comprising a third winder roller (8) and lateral supporting means for said reel (B); means for transferring said reel (B) from said secondary pre-forming cradle (C2) to said main forming cradle (C1), where said transfer takes place without interruption to the winding, of the strip (N) onto said rod (A).

A method of forming a gum roll is provided. The method includes providing a strip stock having a first end, a first surface, and a second surface opposite to the first surface. The first end of the strip stock is coupled to a core fixture so the first surface interfaces with the core fixture. The strip stock is rotated to wind the strip stock onto the core fixture such that the first surface interfaces with the second surface to form the gum roll. The method further includes cutting the strip stock to form the second end when the gum roll is wound to an outer roll diameter, the outer roll diameter being greater than a diameter of the core fixture.

Disclosed is a wind-up system and a method for winding-up a strip. The wind-up system includes a first work station and a first supply member for supplying the strip to said first work station. The first work station includes a first collection area for holding a first collection reel to collect and wind-up the strip; a first liner area for holding a first liner reel to unwind a liner, and a first guide area extending from the first liner area into the first collection area, wherein the unwound liner is unwound from the first liner reel through the first guide area onto the first collection reel. The wind-up system further includes a pick-and-place member for picking-up a leading end from the first supply member and for placing the picked-up leading end of the strip onto the liner within the first guide area.
