摘要： A wet crepe, impingement-air dried process for producing absorbent paper sheet is disclosed. In preferred embodiments, the process utilizes recycle furnish and the web is delaminated as it is wet-creped from a Yankee dryer. Particular embodiments include high consistency (after-crepe) wet-shaping prior to impingement air drying on a drilled vacuum roll.

摘要： 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.

摘要： An apparatus for increasing bulk of a foreshortened fibrous web comprises a working surface designed to receive a foreshortened web thereon, a means for adding moisture to at least selected portions of the web thereby relaxing the crepe in the selected portions, and a means for retaining the crepe in the rest of the web. A preferred apparatus comprises a pair of opposite surfaces, at least one of which having expansion conduits therethrough, the web being impressed between the surfaces. A temperature differential is created between the two opposite surfaces, sufficient to drive the moisture added to the selected portions therethrough, thus relaxing the crepe in the selected portions which expand into the expansion conduits, while the crepe is retained in the rest of the web impressed between the two surfaces.
摘要翻译：用于增加纤维幅材的大部分的装置包括设计成在其上接收经过缩短的幅材的工作表面，用于将水分添加到至少选定的幅材部分中以减轻选定部分中的绉纹的装置，以及用于保持在网页的其余部分绉纹。优选的装置包括一对相对的表面，其中至少一个具有穿过其中的膨胀导管，所述幅材被压在表面之间。在两个相对的表面之间产生足够的温度差异，足以驱动添加到所选择的部分中的水分通过其中，从而在选定的部分中松弛膨胀到膨胀管道中的绉纱，同时绉纹保留在其余的纤维网中在两个表面之间。
