    摘要： A coated abrasive article comprises a backing, a first binder on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable preferably, melt-processable resin containing an epoxy resin, an ethylene-vinyl acetate copolymer, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The above binder precursors of the invention are preferably free of homopolymers and copolymers of olefinic monomers. In another aspect, the invention also describes an energy curable first binder precursor containing an epoxy resin, an ethylene-vinyl acetate copolymer, a polyfunctional acrylate component and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated backing material.

    摘要： Web tension in web material passing through a web transport system is determined in real time using position sensors coupled to driven rollers that define a beginning and an end of a tension zone. The position sensors on the rollers provide information related to the amount of strained web material that has been added and subtracted from the web material present in the tension zone. The amount of web material added to, subtracted from and present in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the present amount of unstrained web material present in the tension zone. Because the length of the tension zone is both fixed and known, the tension in the web material is determined from the present amount of unstrained web material in the tension zone.

    摘要翻译： 通过纸幅传送系统的纸幅材料中的网张力通过与定义张紧区域的开始和结束的从动辊连接的位置传感器实时确定。 辊子上的位置传感器提供了与从张力区域中存在的纤维网材料中加入和减去的应变幅材材料量相关的信息。 然后将在样品时间段内从拉伸区域中减去和存在的纤维网材料的量转化为无限量的纤维网材料，当其组合时，提供存在于张力区域中的当前量的未应变纤维网材料的估计值 。 由于张力区域的长度是固定的并且是已知的，因此幅材材料中的张力是根据张力区域中的当前无量纲的纤维网材料量确定的。
