A rewinding machine winds web material into a log. The machine has a winding drum that is rotatable about a center axis and about which the web material to be wound is directed. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the web material is directed when winding the web material into the log. The continuous loop is configured to move in a direction generally opposite of a direction of the winding drum at the nip. The continuous loop is configured to change speed relative to a speed of the winding drum during winding the web material into the log about a lead edge of the web material. The continuous loop is positionable relative to the winding drum at the nip to accommodate winding the web material into the log about the lead edge of the web material and to sever the web material.

Equipment for removing paper from parent reels used for the production of paper logs of paper material, including a support system adapted to support an exhausted parent reel, where the exhausted parent reel includes a tubular core on which residual paper to be removed is wound, and including removal capabilities for removing the residual paper from the core when the exhausted parent reel is placed on the support system. The removal capabilities include a suction cylinder having a horizontal axis onto which the paper is transferred by effect of the contact between the suction cylinder and the exhausted parent reel and by effect of the rotation of the suction cylinder around the horizontal axis.

A device for rewinding and forming a paper roll in a rewinding machine comprising three rollers with parallel axes and perpendicular to the paper feeding direction, wherein two lower and upper winding rollers supported on a frame cooperate with a third swivel roller in pressure on a roll being formed, the paper being wound provided with a series of transverse piercing and weakening lines spaced apart according to regular intervals along their longitudinal development passing on the upper winding roller and finished roll exiting from an output opening defined between the lower roller and the third roller, the cores for the rolls fed one after the other by a conveyor, wherein mechanical tearing means are placed in the upper roller along its development facing towards the side of the paper facing towards the upper roller to positively act directly at a piercing line and cause the tearing of the paper.

The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller, and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

An apparatus and method for assembling, dispensing and using a laminated paper web transfer tape, an embodiment of the apparatus having a pair of transfer tape spools enclosed within a housing, one transfer tape spool containing a first tape component of the laminated transfer tape and the other transfer tape spool containing a second tape component of the laminated transfer tape, the first tape component being the combination of a substrate having adhesive on both sides and a release liner, the second tape component being a cover flap member having a release coating over at least a majority of one side. The components are unwound from the spools and pressed together such that they become joined along a longitudinal edge strip, then dispensed from the housing. The cover flap member covers one of the adhesive sides of the transfer tape substrate until the moment just prior to transfer of a continuous paper web from a full web spool to an empty web spool, the cover flap member being opened to expose the adhesive by air pressure or resistance.

Rewinding machine comprising a drive unit (1) for supplying a paper veil (2); a winding unit (3) for winding the paper veil supplied by the drive unit into a coil (W) around a winding core (4), comprising a primary roller (6) and a secondary roller (7) rotating in contact with the winding core (4), and a pressure unit (30) provided with a rotating roller (A, B, C) on the coil (W) that is being formed; a core exchange unit (5) for ejecting the formed coil (W) from the machine at the end of a winding cycle and inserting a new core to be wound; separation means (11) for interrupting the continuity of the paper veil at the end of a winding cycle; means for winding a drawing flap (34) of the veil (2) on the new core (4) at the beginning of a new winding cycle.

A web break apparatus is disclosed for cutting and severing a web. The web break apparatus includes a first rotating device that rotates generally at the same speed as a moving web. Positioned on the circumference of the first rotating device is a web engaging device and a straining element. When a web break is desired, the web engaging device and straining element are brought into contact with the web. The web engaging device engages the web, while the straining element causes a web break. The web break apparatus may be used in any suitable winding system. For instance, the winding system may be for winding a web to produce rolled products.

The rewinding machine includes a first winding cradle formed between a first winding roller, a second winding roller and a third winding roller. The first winding roller and the second winding roller define a nip through which there pass the winding cores with the web material being wound around them. The rewinding machine also includes a feed path of the winding cores that pass between the first winding roller and the third winding roller. A second winding cradle is formed between the first winding roller, the second winding roller and a fourth winding roller. The rewinding machine also includes a rolling surface extending around the first winding roller and defining a feed channel of the winding cores.

The invention relates to a method for successively winding a film web onto a plurality of spools, wherein the film web is wound to form a first spool, and a tube and/or winding shaft for forming a subsequent second spool and the film web are moved closer to one another and/or are brought into contact with one another upstream of the first spool. The film web is cut, and thus an end of the film web is produced, with end is wound onto the first spool, and a new start of the file web is produced, which is wound onto the second tube. In order to cut the film web, the film web is cut partially in the transverse direction, at least one cut edge and at least one uncut region remaining in the transverse direction, the uncut region being subsequently torn off or cut off.
