Abstract:
The device for satinizing and embossing metallized or surface-treated packaging foils comprises three embossing rolls, all three embossing rolls cooperating with one another and the packaging foil being capable of being passed under pressure between the first and the second and between the first and the third embossing rolls in order to produce a satin-finish and a pattern. The first, driven embossing roll has a tooth array composed of individual teeth that are arranged in a homogenous grid, and the other two embossing rolls each have a surface structure that differs from that of the first embossing roll. At least one of the additional embossing rolls has structural elements that are arranged individually or in groups but not in the same grid as on the first roll, the structural element being composed of individual teeth and being arranged circularly on the embossing roll. Such an arrangement provides an effective breaking of the paper substrate of the foil and thus a surface having improved properties. Such a surface is particularly suitable for shadow embossing and for embossing authentication and identification features.
Abstract:
The present invention relates to a high speed embossing and adhesive printing process, said process comprising the steps of (a) applying an adhesive to a conformable heated glue application roll; (b) applying said adhesive to a first patterned embossing roll, having an outer surface, which is engaged with a second patterned embossing roll having a complementary pattern to said first embossing roll; (c) passing a web of sheet material between said first and second embossing rolls at a tangential line speed to simultaneously emboss said web and apply said adhesive to said web, such that said adhesive forms an adhesive pattern between embossments; and (d) applying a renewable release agent to the outer surface of the first patterned embossing roll.
Abstract:
엠보싱 및 접착제 도포 방법은 제2 패턴 형성된 엠보싱 롤과 맞물리는 제1 패턴 형성된 엠보싱 롤에 접착제를 도포하는 단계로서, 상기 제2 패턴 형성된 엠보싱 롤은 제1 패턴 형성된 엠보싱 롤과 상보적인 패턴을 갖는 도포 단계와, 웨브를 엠보싱하는 동시에 접착제를 웨브에 대항하여 배향시키기 위하여 시트 재료의 웨브를 제1 및 제2 엠보싱 롤 사이에서 접선 속도로 통과시키는 단계와, 접착제의 적어도 일부가 제1 엠보싱 롤 상에 남게 되고 접착제의 일부가 웨브 상에 남게 되어 웨브 상의 돌출부들 사이에 접착제 패턴을 형성하도록 접착제를 분할되게 하는 단계를 포함한다.

본 발명은 평평한 재료의 엠보싱 및 새티닝을 위한 장치에 관한 것으로서, 보다 상세하게는 핀 업(pin up) 장치인 이(teeth)(2)를 가지는 롤(18)과 상기 이(teeth)에 대응되는 핀 다운(pin down) 장치인 오목부(recesses)(4)를 가지는 롤(19)을 포함하여 구성되는 평평한 재료, 특히 담배, 식품 및 약품을 위한 안쪽 라이너의 엠보싱 및 새티닝을 위한 장치에 있어서, 상기 롤 중 오직 하나에 있어서의 로고에 대응되는 부분은 상기 로고를 형성하도록 가공되고, 반면에 다른 롤 상의 상기 오목부(recesses) 또는 이(teeth)는 그 형상이 변경되지 않는 것을 특징으로 한다. 엠보싱, 새티닝, 로고, 핀 업 롤, 핀 다운 롤
Abstract:
A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.
Abstract:
A process for manufacturing multi-ply disintegratable absorbent sheets is provided. Each said sheet includes at least five plies including two exterior plies and at least three interior plies. Each of at least three of the plies in the sheet is in at least one group of plies and each of the at least three plies is joined to another ply by mechanical deformation.
Abstract:
The foil embossing device has an embossing unit (34) comprising at least two rollers (40, 41) at least one of which (40) is an embossing roller and is driven by a drive (5), at least the embossing roller having teeth (B) that project from the base cylinder for producing logos on the foil in a logo area (27) with teeth (39) that are different from the regularly arranged teeth (A) in order to produce a variable specific embossing pressure on the foil, the rollers having both axially and radially acting centering elements (4, 8) for centering the embossing roller (40) with respect to the other roller (41). It is thus possible to emboss logos in a substantially greater variety of designs and with higher accuracy than in the prior art and thus to achieve a sophisticated esthetic impression.
Abstract:
Methods of mechanically deforming a material are disclosed. The methods of mechanically deforming a material involve using forming members that are moving at different surface speeds relative to each other to form deformed web materials.
Abstract:
A process to mate a plurality of tissue webs includes in one embodiment providing first and second steel rolls and a second steel roll. The first steel roll has first protrusions, and the second steel roll has recesses. The embodiment includes forming a rotary nip between the first steel roll and the second steel roll, and advancing the plurality of tissue webs through the nip. The embodiment includes embossing first and second embossments into the plurality of tissue webs to connect the tissue webs to one another. The first protrusions press a first series of portions of the plurality of tissue webs into the recesses. The second embossments are created by one of pin-to-flat and pin-to-pin embossing. An apparatus suitable for carrying out the process is also disclosed.
