Abstract
A guide carriage assembly that permits adjustment of a relative position of a bearing device, typically a guide wheel, relative to a carriage body is provided. The guide carriage assembly includes a carriage body, at least one support shaft and a guide wheel mounted to the support shaft. The support shaft provides a locating axis about which the support shaft may rotate when mounted to the carriage body. The support shaft further defines an offset bearing axis about which the guide wheel rotates. The offset relationship between the bearing axis and locating axis permits adjustment of the relative position of the guide wheel, or support surface, and the carriage body by rotating the support shaft about the locating axis. The guide carriage assembly may further including locking structure that applies opposing torques about the locating axis to secure the support shaft, and consequently the guide wheel, in the desired location.
