| 20090114347 | Embossing Roller And Method For The Manufacturing Thereof - A method for obtaining an incision in an embossing roller using a hob, with a low-cost technique that enables protuberances that are rounded on top to be obtained, which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances is obtained by machining the cylindrical surface of the roller that is placed between the tailstocks of the lathe using a hob that has teeth, the profile of which in cross-sectional view is complementary to that of the cross-section of the protuberances illustrated in FIG. | 05-07-2009 |
| 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 |

| 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 |

| 20120031564 | 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. | 02-09-2012 |

| 20110128180 | REPLY DETECTION IN A SECONDARY SURVEILLANCE RADAR - The present invention relates to a detecting device for detecting an SSR signal having a characteristic structure. The detecting device comprises filtering means matched to the characteristic structure of the SSR signal, and means for maintaining a false-alarm rate at a substantially constant value. The characteristic structure of the SSR signal comprises either a preamble or an initial pulse and a final pulse separated by a fixed dwell time. The means for maintaining a false-alarm rate at a substantially constant value comprise computing means configured to compute a detection threshold on the basis of a signal supplied by the filtering means, and decision means configured to detect the SSR signal on the basis of the detection threshold and of the signal supplied by the filtering means. | 06-02-2011 |
