摘要： A drip ring for use with a hydraulic cylinder is provided. The drip ring is prefabricated from a flexible material. To size the prefabricated drip ring, the drip ring is cut and wrapped around the hydraulic cylinder that is to be fitted. The amount of excess drip ring material is measured and removed. The properly sized drip ring is then placed around the cylinder such that the two cut edges are positioned within a bonding fixture that has been pre-filled with a bonding compound. The inner flange of the drip ring is secured against the hydraulic cylinder with an adjustable, metal restraining strap. If desired, a drain fixture coupled to a drain pipe is attached to the fitted drip ring.
摘要翻译：提供了一个用于液压缸的滴水环。滴水环从柔性材料预制。为了调整预制滴水口的尺寸，将滴水环切割并包裹在要安装的液压缸上。测量和除去过量滴水环材料的量。然后将适当尺寸的滴水环放置在圆筒周围，使得两个切割边缘位于已经预先填充有接合化合物的接合夹具内。滴水环的内部凸缘通过可调节的金属制动带固定在液压缸上。如果需要，联接到排水管的排水装置连接到装配的滴水环上。

摘要： A process for producing a creped sheet as well as a creping blade and creped paper product formed by such blade is set forth with the process including the steps of adhering a cellulosic web to a moving surface, providing a stepped creping blade disposed to crepe the cellulosic web from the moving surface and creping the cellulosic web from the moving surface forms a creped paper product having greater bulk and absorbency than previously prepared creped paper products. The stepped creping blade used in carrying out the process of the present invention includes an elongated body adapted to be engagable against, and span the width of, the moving surface, the elongated body having a cross section including a relief surface generally facing toward the moving surface, a back surface substantially parallel to the relief surface and generally facing away from the moving surface, a top surface adjacent both the relief surface and a recessed surface with the recessed surface being adjacent both the top surface and the back surface and forming a contact edge with the top surface such that the contact edge engages against the moving surface for creping the cellulosic web from the moving surface. The top surface and the recessed surface form a back step edge while the recessed surface and the back surface form a trailing edge. When utilizing such a blade configuration, the process further includes the steps of first contacting the cellulosic web conveyed by the moving surface with the contact edge, then optionally contacting the cellulosic web creped by the contact edge with the back step edge and subsequently contacting the cellulosic web creped by the contact edge with the trailing edge.
摘要翻译：提出了一种用于生产起皱片材以及由这种刀片形成的起皱刀片和起皱纸制品的方法，该方法包括以下步骤：将纤维素纤维网粘附到移动表面，提供设置成绉纤维素的阶梯式起皱刀片来自活动表面的纤维网和从移动表面起皱纤维素网形成具有比预先制备的起皱纸产品更大的本体和吸收性的起皱纸产品。在实施本发明的方法中使用的阶梯式起皱刀片包括适于可接合并跨越移动表面的宽度的细长主体，细长主体具有横截面，该横截面包括通常面向移动表面，大致平行于所述浮雕表面并且大体上背离所述移动表面的后表面，邻近所述浮雕表面和凹入表面的顶表面，所述凹表面与所述顶表面和所述后表面相邻并且形成触点边缘与顶部表面接触，使得接触边缘抵靠移动表面接合，以使纤维素网从移动表面起皱。顶表面和凹面形成后台阶边缘，而凹面和后表面形成后缘。当使用这种刀片构造时，该方法还包括以下步骤：首先使由移动表面传送的纤维素纤维网与接触边缘接触，然后任选地使由接触边缘起绉的纤维素纤维网与后台阶边缘接触，随后使纤维素纤维网通过与后缘的接触边缘起皱。

摘要： An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.

摘要： The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.
