Abstract: A storage unit for tubular winding cores is described, which includes an entrance, an exit and an accumulation area between the entrance and the exit. In the accumulation area, a feeding path is provided for the tubular winding cores, formed by feeding channels overlapping and connected by descending branches arranged for falling due to gravity from one feeding channel to another feeding channel therebelow. The tubular winding cores gather along the feeding path, arranging themselves in contact one with another.
Abstract: The cutting machine includes at least one log feed channel; a cutting station along the feed channel, with at least one cutting blade for dividing each, log into individual rolls plus front and rear trims; a log feed device along the feed channel, including at least one rear member for pushing the logs to be cut, movable along the feed channel to push each log through the cutting station. The feed device also includes at least one front member for engaging with the log to be cut, arranged and controlled so as to engage frontally with each log, or series of rolls obtained after the log has been cut, for at least a part of its travel along the feed channel.

Abstract: A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll.
Abstract: A rewinder machine for the production of rolls of web material is described, comprising: a winder unit (3, 5, 7); a path for delivering the web material (N) to said winder unit; a system for continuously feeding said web material into said winder unit; a distributor (31) of a sheet material (F) for wrapping the rolls formed by said winder unit, installed and operated so as to deliver a length of sheet material to said winder unit on completion of the winding of each roll without stopping the forward feed of the web material.
Abstract: The winding mandrel includes a substantially cylindrical wall with expandable members for the torsional locking of tubular winding cores. At least one portion of the wall is made of carbon fiber in a polymer resin matrix.
Abstract: A rewinding machine for producing logs of web material is described which includes a winding unit; a feed path of the web material towards the winding unit; a severing device to sever the web material upon completion of winding each log; and a glue dispenser to apply a glue to the web material. The machine also includes a diverter member disposed and controlled to temporarily divert the web material towards the glue dispenser.

Abstract: 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.

Abstract: A method for producing an article made of a web material, comprising at least one ply, wherein a superabsorbent material in powder form is associated with said ply.
Abstract: A method is described for obtaining a coreless roll (R) of web material with a first portion of web material forming an inner nucleus (R1) of said roll and a second portion of web material (R2) wound around the outside of said nucleus. The two portions (R1, R2) can be separated from one another and, for said purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll, between said inner nucleus and said second portion of web material, so as to facilitate the extraction of the inner nucleus from the outer portion of the roll.
Abstract: The rewinding machine includes a weakening device for weakening the web material along a substantially transverse weakening line, along which the web material is severed at the end of the winding of a log. The weakening device is controlled so as to generate the weakening line in a manner synchronized with the completion of winding of the log.
Abstract: The device comprises at least a continuous movable flexible member (23) carrying a series of contact members (29, 29A, 29B) for the products (R; R1; RN) aligned with one another. A section of the movable flexible member is devoid of said contact members to allow the trimmings (Rc, Rt) to fall. At least a longitudinal supporting element (21) of the products (R; R1, RN), is also provided, parallel to the movable flexible member, the reciprocal position of said flexible member and of said longitudinal element being such that the products advance in contact with the contact members (29, 29A, 29B) of the flexible member and with the longitudinal element. A pusher (11) inserts the series of products with the respective trimmings between the flexible member and the longitudinal supporting member. The flexible member (23) is controlled with a variable speed to carry the section thereof devoid of contact members time by time to the level of the head and tail trimmings (Rc; Rt) of two consecutive series of products.

Abstract: The rewinding machine comprises: a first winding roller (11) and a second winding roller (13) defining a nip (15) through which said cores are inserted and through which said web material (N) is fed; and at least one pair of motorized engaging members (57), to engage the ends of a winding core and transmit a rotational movement to the core during at least part of the winding cycle of each log. The engaging members and the first and second winding roller are produced and disposed so that the log being formed is in contact with said first and said second winding roller. Moreover, a third winding roller (17) is provided, defining a winding space with said first and said second winding roller, said third winding roller being movable to allow increase and completion of winding of each log in said winding space.
