摘要： A system for embossing a substantially continuous web (10,16) of material including a supply for supplying at least one substantially continuous web (10,16) of material, feeding the substantially continuous web of material (10,16), an embossing device for embossing a predetermined pattern in the web material (10,16) and a take-up device for taking-up the embossed web material; wherein at least one roll (100) of the system includes an elongated core (107) formed of a substantially rigid material and an elongated sleeve (103) formed of a material less rigid than the elongated core (107) with the elongated sleeve (103) being releasably secured to the core (107) such that the elongated sleeve (103) is axially and circumferentially fixed with respect to the core (107) when in operation and can be selectively axially removed from the core (107). Preferably, the sleeve (103) includes an embossing pattern laser engraved thereon so as to permit the embossing pattern being run by the system to be readily changed.

EP0770477A2 Method and apparatus for pinch perforating multi-ply web material 失效

摘要： A method and apparatus for pinch perforating multi-ply web material (2) to increase the perforation ply bond and/or perforation ply bond retention by pinching the multiple plies of web material together and then perforating the material using an anvil (25) and perforator blade (7) design provided on a perforating apparatus. Specifically, the apparatus comprises a roll mounted contoured perforator blade (7) which cooperates with a beveled anvil (25) to produce perforation ply bonds perpendicular to the length of the multiple plies of web material (2). The desired anvil/perforator blade interface angle between 0° and 20° is provided by beveling the anvil. A 15° beveled anvil is preferred to provide a 5° anvil/perforator blade interface angle. By pinching and bonding the leading edges and other predetermined points of the multi-ply tissue paper together before cutting, the likelihood of ply separation, missing plies and ply mismatch is greatly reduced.
摘要翻译：一种用于夹紧多层腹板材料（2）的方法和装置，以通过将多层纤维网材料夹在一起然后使用砧座（25）和穿孔器对材料进行穿孔来增加穿孔层粘结和/或穿孔层粘结保持力提供在穿孔装置上的刀片（7）设计。具体地说，该装置包括一个滚轮安装轮廓的穿孔刀片（7），它与一个斜面的砧座（25）配合，以产生垂直于纤维网材料（2）的多个层的长度的穿孔层。通过对砧座进行斜切来提供0°至20°之间所需的砧座/穿孔机刀片接口角度。 15°倾斜砧座优选提供5°砧座/穿孔机叶片接口角度。通过在切割之前将多层薄纸的前缘和其他预定点捏合在一起，可大大降低层间分离，缺失层和层错配的可能性。
