Simplified mount for a web-supporting roller

Abstract

A web transport apparatus including a simplified mount for a web-supporting roller, providing the axis of such roller with two degrees of freedom of movement. The simplified roller mount comprises an elongated, substantially planar, flexure member having a stiffening rib located along its longitudinal axis to limit flex of the member to movement about its longitudinal axis. A pin is supported by the flexure member. The pin lies substantially in the plane of the flexure member with the longitudinal axis of the pin perpendicular to the longitudinal axis of the flexure member. The web-supporting roller is carried, for example by a yoke supported on the pin for movement with a first degree of freedom about the longitudinal axis of the pin and with a second degree of freedom about the longitudinal axis of the flexure member.
