    摘要： An axle or roll assembly has an axle which is split along part of its length to form two elements. Curvature is introduced into the axle by tensioning one axle element and applying a reaction in compression to another. The axle is supported adjustably in end supports so that the orientation of its plane of curvature may be altered. An adjusting means is threaded axially on a free end of one of the axle elements, and bears axially against a free end of the other. Releasable clamping means restrain the axle against rotation, so that rotation of the adjusting means changes the degree of curvature of the roll. Upon release of the clamping means, rotation of the adjusting means rotates the axle bodily to change the orientation of its plane of curvature, without changing the amount of curvature.

    摘要： An apparatus for controlling the lateral position of a web of material, having a sensing head with three pneumatically operated sensing elements each of which senses the presence or absence of the web in the head. First and second sensing elements are nominally disposed with one longitudinal edge of the web therebetween and the third sensing element is disposed inwardly of the element nominally sensing the presence of the web so as to do likewise. Signals from the first and second elements are fed to a control means which activates an adjusting device to maintain the web in a desired lateral position while signal from the third sensing element indicating absence of the web is used to inhibit the operation of the adjusting device.
