Abstract
The rewinding machine comprises: winding elements (1, 3, 5) to wind the web material (N) and form the logs (L1, L2); at least a first glue dispenser (31B) to apply a first glue (C2) to a portion of said web material, in proximity to a severing line, along which the web material is severed upon termination of winding a log. The first glue dispenser comprises a mechanical element (31B) that touches the web material (N) upon termination of winding each log (L1, L2), to transfer the first glue to the web material (N).
Claims36
A peripheral rewinding machine for producing logs of wound web material comprising:
- a winding cradle to wind web material and form said logs, including at least a first winding element around which said web material is fed;
- a feeder to feed tubular winding cores, around which said logs are to be wound, towards said winding cradle;
- a means to sever the web material upon termination of winding each log;
- at least one first glue dispenser including a mechanical member that touches the web material at end of winding of said each log, to apply a first glue to a portion of said web material, in proximity to a severing line, along which the web material is severed upon termination of winding said each log to form a final free edge and-an initial free edge, said first glue gluing the final free edge of the log;
- wherein said mechanical member is integral with said feeder.

A rewinding machine for producing logs of wound web material, comprising:
- a winding cradle to wind web material and form said logs, including at least one first winding element around which said web material is fed;
- means to sever the web material upon termination of winding each log, including a rotating severing element, cooperating with said first winding element
- at least one first glue dispenser including a mechanical member that touches the web material at end of winding of said each log, to apply a first glue to a portion of said web material, in proximity to a severing line, along which the web material is severed upon termination of winding said each log to form a final free edge and an initial free edge, said first glue gluing the final free edge of the log;
- wherein said mechanical member of said first glue dispenser is integral with said severing element or is part of said severing element.
1 more element
Rewinding machine to produce logs of web material wound on a winding core, comprising:
- winding elements to wind web material and form said logs;
- a severing element to sever the web material upon termination of winding each log, to form a final edge of a finished log and an initial edge of a subsequent log;
- a feeder to feed tubular winding cores towards said winding elements;
- at least a first glue dispenser to apply a first glue to said winding cores, as at least one longitudinal band;
- said feeder and said severing element being disposed and controlled so that upon termination of winding said each log, the web material is severed and said longitudinal band of glue applied to said core is brought into contact with said web material after the web material has been severed, so that at least part of said first glue is transferred to the web material in a vicinity of the final free edge of the finished log, to glue the final free edge of the log.

Method for producing logs of wound web material, comprising:
- winding a quantity of web material to form a first log in a winding area;
- upon termination of winding said first log, severing the web material to create a final edge of the first log and an initial edge to form a second log;
- applying a first glue to a portion of the web material destined to remain wound on the first log, in proximity to the final free edge, which is glued to the first log upon termination of winding,
- wherein said first glue is applied to the web material by means of a feeder of said tubular cores, during insertion of a core towards said winding area.

Method for producing logs of wound web material, comprising:
- winding a quantity of web material to form a first log in a winding area;
- upon termination of winding said first log, severing the web material to create a final edge of the first log and an initial edge to form a second log;
- applying a first glue to a portion of the web material destined to remain wound on the first log, in proximity to the final free edge, which is glued to the first log upon termination of winding,
- wherein said first glue is applied to the web material by a severing element that also severs the web material upon termination of winding each log.
1 more element
Method to produce logs of wound web material, comprising:
- winding a quantity of web material around a first winding core to form a first log in a winding area;
- upon termination of winding said first log, severing the web material to produce a final edge of the first log and an initial edge to form a second log;
- a applying a first glue to a second winding core, said first glue being applied according to at least one longitudinal band essentially parallel to the axis of said core;
- after severing of said web material, bringing said longitudinal band of first glue applied to the second core into contact with said web material;
- transferring at least part of the first glue from said core to said web material, in proximity or at a level of said final free edge, to close the final free edge of the first log.
