Abstract
The rewinding machine includes a winding system and a feed path for a web material towards the winding system. Along the feed path is a channel for insertion of the cores and an interruption member which acts on the web material.
Claims62
A rewinding machine for winding a web material into logs comprising:
- a feed path for feeding web material towards a winding system;
- an interruption member to interrupt the web material at an end of winding of a log;
- a core feeder to sequentially insert winding cores in a channel defined by a rolling surface and a movable core feed member constructed and arranged so that when a core is inserted in said channel the web material is between said core and said feed member and in contact with said feed member, said feed path extending along said channel;
- wherein said interruption member is associated with said feed member, wherein said interruption member is arranged on a side of said feed path which includes said feed member and said side of said feed path being opposite said rolling surface and said interruption member being positioned at least partly on an opposite side of said feed member with respect to said channel to act on the web material through said feed member, and wherein said interruption member is timed to operate when the web material is to be severed.

A method for producing logs of wound web material comprising:
- feeding a web material to a winding system along a feed path extending along a channel defined between a rolling surface and a movable core feed member;
- winding a first log of web material around a first winding core;
- inserting a new winding core in said channel and feeding said core along said channel with the web material between said core and said feed member;
- and
- interrupting the web material at an end of winding of said first log forming a final free edge of said first log and an initial free edge for winding of a second log,
- wherein said web material is interrupted by an interruption member which is activated at predetermined times to act on the web material along the channel on a side of the feed path which includes said interruption member and said feed member and opposite said rolling surface which is across from said feed member.
