摘要:
The unwinder device includes an unwinding station (7), with unwinding members for unwinding reels and a splicing device (151) for splicing together web-like materials (N1 and N2) coming from a first reel (B1) and from a second reel (B2). At least two supports (49, 51) are arranged in the unwinding station for the respective reels of web-like material, associated with respective unwinding members (83, 99). The supports are constructed and arranged to simultaneously support two reels being unwound, during at least a phase of the unwinding, and each of said supports is able and constructed to load a new reel in an engagement position, support it during the unwinding and unload it in a release position.

The unwinding device to unwind reels of web material comprises: unwinding members (505; 525) to simultaneously unwind a first reel (B1) and a second reel (B2); a splicing device (563) to join together a first web material (N1) coming from the first reel (B1) and a second web material (N2) coming from the second reel (B2); at least one accumulation member (540, 541) to accumulate the web material delivered from the second reel before splicing with the web material delivered from the first reel; a first path (585) and a second path (589) for the web material delivered simultaneously from the first and from the second reel towards a machine downstream.
摘要:
The rewinding machine includes a first winding roller, around which the web material is guided, and defining at least in part a winding cradle; a support surface of the winding cores arranged to receive a winding core and to convey the core toward the winding cradle, the support surface defining with the first winding roller a feed channel of winding cores, a severing member of the web material, which can be inserted in the channel to sever the web material, the severing member interacting with the web material to cause severing thereof; a motor for controlling the severing member, the motor controlling the severing member modifying the speed of the severing member when it is positioned inside the channel.
摘要:
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.
