摘要： A stationary working surface of a one roll microcreper member is of plastic resin having low wear and friction properties. As a primary pressing member subject to concentrated force it is 0.040 inch thick. One or both opposed retarder members of a bladed microcreper are of the plastic. Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed. By a load-spreading surface, the thermoplastic primary member is restrained without distortion. A primary member shown is sheet form, mounted between sheet metal members, one with a restraint surface. Sheet materials of polyolefins, wood pulp, etc. are dry microcreped at improved rates and materials not heretofore capable of being processed can now be processed. By introducing a sheet material having abrasive quality, wear-in of a primary pressing member provides a curved primary pressing surface fitted to the local shape of the drive roll, for improved feeding and microcreping of the material.
摘要翻译：单辊微量清洗器构件的固定工作表面是具有低磨损和摩擦性能的塑料树脂。作为集中力的主压制件，厚度为0.040英寸。叶片式微反应器的一个或两个相对的缓速构件是塑料。热塑性塑料会磨损和摩擦限制，例如超高密度聚乙烯。主要构件延伸部分，一些具有开口，槽或孔用作柔性延迟器以接合经处理的材料。优选地通过水射流切割形成的平行狭缝限定机器方向的手指提供了特别的优点，当手指开始在起皱腔的上游时，通常最大，并且观察到所述的尺寸限制。通过负载扩展表面，热塑性主要部件被抑制而没有变形。所示的主要构件是片状，安装在钣金构件之间，一个具有约束表面。聚烯烃，木浆等的片材以提高的速率进行干式微量冲洗，现在可以处理迄今为止不能加工的材料。通过引入具有磨料质量的片材，初级加压件的磨损提供了适配于驱动辊的局部形状的弯曲的初级按压表面，用于改善材料的进给和微量冲洗。

摘要： A rolled paper embossing dispenser in which the paper is embossed and from which the paper is simultaneously dispensed. The dispenser includes a nip formed by a first embossing roll and a second embossing roll, both rotatably mounted within a cabinet. The first embossing roll has a plurality of spaced-apart annular bands with each annular band including discrete, spaced-apart knuckle projections extending radially from the roll. The second embossing roll includes annular slots and annular extensions arranged in alternating relationship with each annular slot having sufficient width to receive the knuckle projections without contacting any portion thereof as paper is fed through the nip and embossed. A lever or crank is provided for a user to rotationally drive one of the embossing rolls, the other embossing roll rotating only in response to the paper being drawn through the nip such that rotational slippage of one roll with respect to the other will not result in breaking or tearing the web.
摘要翻译：一种卷纸印花分配器，其中纸被压花并同时分配纸张。分配器包括由第一压花辊和第二压花辊形成的辊隙，两者都可旋转地安装在机壳内。第一压花辊具有多个间隔开的环形带，每个环形带包括从辊径向延伸的离散的间隔开的转向节突起。第二压纹辊包括环形槽和环形延伸部，其与具有足够宽度的每个环形槽相互交替地布置，以便在纸张被馈送通过辊隙并压花时接收转向节突起而不接触其任何部分。杠杆或曲柄被设置用于使用者旋转地驱动一个压花辊，另一个压花辊仅仅响应于纸张被拉过辊隙而旋转，使得一个辊相对于另一个辊的旋转滑动不会导致打破或撕裂网。
