  • Rewinding machine and method for the formation of logs of web material with means for severing the web material
    Patent number: 7318562
    Abstract: The rewinding machine for the formation of logs (L) of web material (N) wound on a core (A), includes a first winder roller (15) around which the web material (N) is fed, and a second winder roller (17) forming, with the first winder roller, a nip (19) through which the core (A) and the web material (N) pass. A web material-severing device (43) cooperates with the first roller (15). Located upstream of the nip (19), with respect to the direction of movement of the web material (N), is a surface (33) defining, with the roller (15), a channel (39) into which the core (A) is inserted. A conveyor (47; 57; 67) introduces a core into the channel (39). The material-severing device (43) cooperates with the roller (15) along the channel (39) between the region of insertion of a new core and the nip (19).

  • Rewinder for producing logs of web material, selectively with or without a winding core
    Patent number: 5603467
    Abstract: A surface automatic rewinder for winding web material (N) in logs or rolls (R) is described, including a first winder roller (1), a second winder roller (3) which defines, with the first winder roller, a nip (5) through which the web material is fed, core feeder (19, 21) to feed the cores (A) on which the web material is wound for the formation of rolls or logs, and an inserter (27) for inserting the cores into the nip (5). The rewinder is characterized in that the inserter (27) may be moved to an inoperative position whereupon the winding of the web material can be accomplished without a winding core.
