20120021887 | DEVICE FOR SEPARATING PACKS OF SHEET PRODUCTS AND MACHINE USING SAID DEVICE - The device includes a feed path for the products, along which the products move forward, divided into single packs with the interposition of at least one separator finger between one pack and the next; an oscillating support to receive packs of products and tip them onto a conveyor below; a front retaining element, which can be inserted and removed with respect to the feed path of the products to frontally retain the pile of products while the oscillating support performs an oscillation movement and deposits a pack on the conveyor below. The front retaining element is inserted in a space formed between the first and the second pack of the pile. The space is obtained by oscillating the support downwards. The oscillating support moves downwards by a first downwards angular movement and a second angular movement. | 01-26-2012 |
20120186751 | Coreless roll of web material, machine and method for its production - A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll. | 07-26-2012 |
20120297944 | MACHINE FOR CUTTING WEB ROLLS - The cutting machine includes at least one log feed channel; a cutting station along the feed channel, with at least one cutting blade for dividing each, log into individual rolls plus front and rear trims; a log feed device along the feed channel, including at least one rear member for pushing the logs to be cut, movable along the feed channel to push each log through the cutting station. The feed device also includes at least one front member for engaging with the log to be cut, arranged and controlled so as to engage frontally with each log, or series of rolls obtained after the log has been cut, for at least a part of its travel along the feed channel. | 11-29-2012 |
20140000830 | METHOD AND DEVICE FOR JOINING PLIES OF PAPER | 01-02-2014 |
20140044923 | Embossing Roller, Embossing Unit, Embossing Method And Embossed Product - The embossing unit includes at least one embossing roller with a rotation axis and a substantially cylindrical surface with a plurality of embossing protuberances with linear extension; a pressure roller with a yielding surface; an embossing nip defined between the pressure roller and the embossing roller; a feed path of a web material extending through said the embossing nip. Along the linear extension thereof the embossing protuberances have a variable inclination with respect to the rotation axis of the embossing roller and a variable cross section along the longitudinal extension of the embossing protuberances. | 02-13-2014 |
20150041045 | GLUING DEVICE FOR LOGS OF WOUND WEB-LIKE MATERIAL - The gluing device includes a log feeding path that extends at least partially between a flexible conveying member and a feeding surface; and a log inserter that sequentially introduces logs between the flexible conveying member and the feeding surface. The inserter includes a flexible input member, provided with pushing elements for pushing single logs between the flexible conveying member and the feeding surface. | 02-12-2015 |

20120168553 | WINDING MANDREL FOR THE PRODUCTION OF REELS OF WEB MATERIAL - The winding mandrel includes a substantially cylindrical wall with expandable members for the torsional locking of tubular winding cores. At least one portion of the wall is made of carbon fiber in a polymer resin matrix. | 07-05-2012 |
20120308348 | STORAGE UNIT FOR TUBULAR WINDING CORES - A storage unit for tubular winding cores is described, which includes an entrance, an exit and an accumulation area between the entrance and the exit. In the accumulation area, a feeding path is provided for the tubular winding cores, formed by feeding channels overlapping and connected by descending branches arranged for falling due to gravity from one feeding channel to another feeding channel therebelow. The tubular winding cores gather along the feeding path, arranging themselves in contact one with another. | 12-06-2012 |
20130020427 | REWINDING MACHINE AND WINDING METHOD - 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. | 01-24-2013 |
