Abstract in simplified Chinese:高膨松度薄织物经由连续地通过分离之压延与压纹拷花单位的处理,以便能仅量达成缠绕张力之薄板测径厚度与模型花样明晰度之压纹拷花组件高度间的最佳平衡,其结果形成一具有改良压纹拷花模型清晰度的拷花、高膨松度薄织制品。此多重步骤的改造制程,可利用一具有高度约为0.04英吋或更高的凸状压纹拷花组件。此薄织物具有一剩余波纹值为12微米或更大,其可归因于平均表面波纹值为30微米或更大的点状浮凸花纹。
Abstract:
An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern includes the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.
Abstract:
A fibrous product includes at least one top ply with an embossing pattern forming pillow-like chambers at least partially surrounded by first embossing protuberances; at least one middle ply embossed in register with the at least one top ply so that second embossing protuberances of the at least one middle ply nest into the pillow-like chambers of the at least one top ply; and at least one bottom ply in register with the at least one top ply and the at least one middle ply being bonded to both the at least one top ply and the at least one middle ply at bonding regions. The at least one bottom ply includes non-embossed areas and embossed areas provided with a micro-embossing pattern, whereby the unembossed areas of the bottom ply are in register with the top ply and the middle ply.
Abstract:
An embossing device, such as a cylinder or a sleeve, includes on an outer peripheral surface an embossing raised and recessed pattern, to be reproduced on a deformable planar substrate. The cylinder or sleeve bears a photopolymer coating the outer surface which has the raised embossing pattern.

Abstract:
The rotating cylinder for processing a web material comprises an essentially rigid cylindrical core (13), on which is fitted an interchangeable sleeve (45) of elastically expandable material whose rigidity is less than that of the material of the core; the sleeve is axially and angularly fixable to the core and is provided on its outer surface with a relief pattern. For each end of the 3 cylinder, there is provided at least one corresponding mechanical locking member which can be fixed to the corresponding end of the core of the cylinder and which interacts with the corresponding end of the interchangeable sleeve to lock the interchangeable sleeve angularly with respect to the core of the cylinder.
Abstract:
A method of embossing an absorbent web with a machine direction undulatory structure is described. The web has a plurality of ridges extending in its machine direction occurring at a frequency, F, across the web and the method includes providing the web to an embossing station where the web is embossed between a first and second embossing roll, each of which rolls may be provided with a plurality of embossing elements configured to define a plurality of embossing nips. At least a portion of the embossing nips are substantially oriented in a cross-machine direction with respect to the web and have a cross direction length, L. The product F×L is from about 0.1 to about 5.
Abstract:
In a method for the manufacture of an embossing due for the cold and hot embossing of paper and cardboard a plane material impregnated with a duroplastic resin is brought into close contact with a shaping die, both are pressed together to obtain a press die from a plane material impregnated with duroplastic resin after hardening of the materials brought into contact with each other.
