20090173819 | Method and Device for Producing Logs of Web Material With a Mechanism for Interrupting the Web Material Activated by Passage of the Winding Cores - The rewinding machine includes: a winding unit; a feed path of the web material; an insertion path of the winding cores; a separator device to sever the web material upon completion of winding each log. The separator device is disposed and produced to be activated by passage of a winding core. | 07-09-2009 |
20100025515 | Method and device for gluing the free edge of a log of web material in a rewinding machine - A rewinding machine for producing logs of web material is described which includes a winding unit; a feed path of the web material towards the winding unit; a severing device to sever the web material upon completion of winding each log; and a glue dispenser to apply a glue to the web material. The machine also includes a diverter member disposed and controlled to temporarily divert the web material towards the glue dispenser. | 02-04-2010 |
20100101705 | METHOD AND DEVICE FOR CLOSING THE TAIL END OF A LOG WEB MATERIAL AND LOG OF OBTAINED - To close the tail end (L) of the web material forming the log (R) there is provided mechanical ply-bonding between the tail end and a portion of the last turn of web material, preferably a portion forming a fold (F) projecting from the log. | 04-29-2010 |
20100222194 | Machine for the Production of Tubes by Winding Strips of Weblike Material - The machine for producing tubes includes a winding spindle, around which strips of weblike material are wound to form the tube, which is made to advance along the spindle; a device for supply and winding of the strips around the spindle, and at least one knife for cutting lengths of the tube being formed. The knife is provided with a reciprocating movement parallel to the spindle. There is moreover envisaged a counter-knife within the tube being formed, provided with a movement of translation synchronized to the movement of translation of the knife. The counter-knife is magnetically constrained to a mover member, which transmits the motion to the counter-knife. | 09-02-2010 |
20110265954 | Method and device for closing the tail end of a log of web material and log obtained - To close the tail end (L) of the web material forming the log (R) there is provided mechanical ply-bonding between the tail end and a portion of the last turn of web material, preferably a portion forming a fold (F) projecting from the log. | 11-03-2011 |
