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.

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.

Provided is a rewinding machine including a winding zone wherein a continuous strip is wound around a core; a movement unit of the continuous strip defining a sliding surface for the continuous strip; a support unit defining a support surface for the core; the support surface is opposite and spaced from the sliding surface so as to define a sliding channel, configured to guide the core in the winding zone; a contrast unit defining a contrast surface; and a tearing tooth configured to press the continuous strip against the contrast surface causing the tearing of the continuous strip; said sliding surface being interposed between the support surface and the contrast surface.

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.

Device for controlling the separation of the sheets of paper webs rolled in the form of logs, comprising a guide roller (RA) cooperating with further means (R4, R5) for rolling a paper web (2) so as to form a paper log and cooperating with means for providing pre-incision lines on the paper web (2) so as to divide it in multiple separable sheets. The device comprises pneumatic separation means (SP) adapted to direct a fluid jet (J) toward a pre-incision line (p) which separates the last sheet (LS) of a log (RO) in the course of formation from the first sheet (FS) of a subsequent log to be formed. The pneumatic separation means (SP) are inside the guide roller (RA) and the latter has an outer surface (72) with a plurality of through holes (73) allowing the fluid jet (J) produced by the pneumatic separation means (SP) to be directed towards the pre-incision lines (p). The device comprises suction means (200, 201) arranged downstream of the separation means (SP) relative to a direction (K) of rotation of the guide roller (RA). The suction means (200, 201) are inside the guide roller (RA). The suction means (200, 201) provoke a suction through the holes (73).

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.

A rewinding machine is described with a winding cradle defined by three rollers and including a fourth winding roller defining with the first winding roller a cradle in which the web material is pushed by a winding core to the beginning of each winding cycle, to cause severing of the web material without the need for controlled mechanical parts.

A paper tape turn-up construct including a cover flap and a multi-bend structure to both protect an adhesive layer and to build an optimized elevated structure to present the adhesive layer during initiation of the paper web turn up process. Methods and apparatus to form the constructs and apply the constructs to paper production equipment are also included. The multi-bend paper turn up construct includes layers of adhesive and pulpable substrate with strategically located release materials, such as silicon that enhance a bridging of a gap between a rotating paper web and an empty spool surface.

A rewinding machine includes a drawing assembly (1), a winding assembly, a core-change assembly (5), and pneumatic elements for interrupting the continuity of the ply at the end of a winding cycle, and for starting a new winding cycle.
