Abstract:
A process for making continuous stretchable substrate products comprising the steps of supplying a web of stretchable substrate having a first surface and a second surface, embossing at least one of the surfaces of the web substrate with an embossed image using at least one embossing roller, printing at least one of the surfaces of the web substrate with a printed image using at least one printing roller; wherein the embossed image and the printed image are disposed onto the substrate relative to each other such that a print/emboss registration is created, measuring the angular location of one embossing roller and translating that location into a digital signal, measuring the angular location of one printing roller and translating that location into a digital signal, manually zeroing the print/emboss registration; and automatically controlling the print and emboss rolls to maintain registration using a control program that comprises the steps of i) comparing the digital signal from the embossing roller and the digital signal from the printing roller, and ii) correcting the angular location and angular speed of either the embossing roller or the printing roller.
Abstract:
The invention relates to apparatus clamping at least one paper or non-woven sheet and including two cylinders which run substantially tangent to one another. At least one of the cylinders has on its surface and in a zone that makes contact with the sheet a clamping band having first salient elements. The interaction of the two cylinders in the presence or absence of the sheet subtends an active surface during the rotation of the cylinders. In the invention, at least one of the cylinders has on its surface and in a zone (nip) that makes contact with the other cylinder by means or not of the sheet a load compensating band having second salient elements. This band is selected so that the variation of the consecutive instantaneous active surfaces of the clamping band and of the load compensating band is less than the variation of the consecutive instantaneous active surfaces of the clamping band alone. The invention applies in particular to converting paper or non-woven sheets in the manufacture of absorbent paper items, such as tissues or table napkins.
Abstract:
A paper sheet having several distinct layers comprised of at least two plies of paper glued together in discrete areas and characterized by having patterns which correspond to areas of reduced thickness on both outer surfaces of the plies of paper.
Abstract:
A method of printing color images which includes the formation of a pattern of three primary color separated halftones of the image from a medium applied to a substrate. The medium is embossed to form a surface relief configuration on each halftone image. Each surface relief configuration reflects one specific primary color at a specific angle. In one embodiment, the medium is applied to a substrate in the pattern of color separated halftone images in a single printing pass by a composite offset printing plate. The medium is then embossed by an embossing plate to create the surface relief configurations thereon. In a second embodiment, the medium is applied to the substrate and embossed by a single plate in a single printing pass. In a third embodiment, the medium is applied to the substrate in a relatively continuous layer and thereafter embossed to simultaneously create a pattern of color separated halftones of the image and a different surface relief configuration on each halftone image. In a fourth embodiment, the medium is applied to the substrate in a relatively continuous layer and thereafter embossed to form a plurality of surface relief configurations thereon. The halftone images are then formed on the embossed medium to produce a full color image by applying a coating over the portions of the medium where the primary colors should not be reflected.
Abstract:
A MACHINE FOR PRODUCING LAMINATED EMBOSSED WEBS USEFUL AS TOWELING, NAPKINS, PLACEMATS AND THE LIKE. THE MACHINE EMPLOYS A NOVEL ARRANGEMENT OF EMBOSSING AND LAMINATOR ROLLS TO ACHIEVE A NESTED CONFIGURATION OF THE EMBOSSED, INWARDLY-EXTENDING PROJECTIONS AND AVOIDS THE SPEED LIMITATIONS INHERENT IN PRIOR MACHINES.
Abstract:
For the production of a sheet product including at least two layers (V1, V2) it is suggested, among other things, an embossing device including a first pressure roller (5; 105) interacting with a first and a second embossing cylinder (1, 3; 101, 103) provided with respective points (1P, 3P, 101P, 103P) on their cylindrical surface.
Abstract:
(과제) 합성수지 레이스 모양지의 성형과 그 표면을 다색으로 착색 인쇄하는 것이 동시에 행해지게 한다. (해결수단) 성형롤(4)의 둘레표면에 평탄한 레이스부(2)와 입체적 부출모양부(3)를 형성시키는 오목형(h1∼h3)을 설치하고, 그 성형롤(4)의 둘레표면은 평탄한 레이스부(2)를 형성시키는 오목형(h1) 부분을 약 20μ정도 깎아 성형롤(4)의 둘레표면 보다 평탄한 레이스부(2)의 오목형(h1)을 부출모양(3)의 오목형(h2, h3) 보다 안쪽에 위치시킴으로써 부출모양부(3)와 평탄한 레이스부(2)에 경계선을 형성하고, 또한 그 성형롤(4)상에 복수의 착색기구(12a∼12c)를 설치하여 각 오목형(h1∼h3)에 상이한 색조(A), (B), (C)의 잉크를 공급하여 전사시켜 그 오목형(h1∼h3)에 용융한 합성수지를 충전시킴으로써 색 엇갈림이나 혼색에 의한 인쇄 빗나감을 없애고 선명하게 착색된 착색 레이스 모양지(1)를 제조한다.
