    • A method of controlling a moving web in relation to a selected transverse position comprising positioning a first positioning guide proximate a second positioning guide wherein the second positioning guide has a mechanism for positioning the web having minimal backlash. The web is passed through the first positioning guide and the second positioning guide. A sensor detects the transverse position of the moving web at the second positioning guide. The sensor transmits the transverse location of the web at the second positioning guide to a controller. The controller manipulates a zero-backlash actuator wherein the zero-backlash actuator is coupled to the second positioning guide such that the transverse position of the web is controllable to within a preselected dimension of the selected transverse position.
    • 一种相对于所选择的横向位置控制移动幅材的方法,包括将第一定位引导件定位在第二定位引导件附近,其中所述第二定位引导件具有用于定位具有最小间隙的所述幅材的机构。 纸幅通过第一定位引导件和第二定位引导件。 传感器检测在第二定位引导件处的移动幅材的横向位置。 传感器将纸张在第二定位导轨上的横向位置传送到控制器。 控制器操纵零间隙驱动器,其中零间隙驱动器联接到第二定位引导件,使得幅材的横向位置可控制到所选横向位置的预选尺寸内。

    • A system and method for controlling curl in multi-layer webs. The method can include providing a coated web, bending the web to induce a strain or pre-curl in the web, and curing the coating to form a multi-layer web. Some coatings at least partially shrink when cured such that curing the coating induces a curl in the multi-layer web. Bending the web occurs prior to curing the coating, and the pre-curl can be configured to at least partially counteract the curl induced by curing to form a multi-layer web having a desired curvature. The system can include a curing section configured to cure a coating, and can further include a web bending section configured to bend the web to induce a strain in the web. The web bending section can be positioned upstream of the curing section such that the web is bent prior to the coating being cured.
    • 一种用于控制多层腹板卷曲的系统和方法。 该方法可以包括提供涂布的网,弯曲网以在网中引起应变或预卷曲,并固化涂层以形成多层网。 当固化时,一些涂层至少部分地收缩,使得固化涂层在多层织物中引起卷曲。 在固化涂层之前发生卷曲,并且预卷曲可以构造成至少部分地抵消由固化引起的卷曲,以形成具有期望曲率的多层织物。 该系统可以包括被配置为固化涂层的固化部分,并且还可以包括网状物弯曲部分,其被配置为弯曲卷材以在卷筒纸中引起应变。 腹板弯曲部分可以位于固化部分的上游,使得在涂层被固化之前纤维网被弯曲。
