DEFINITION

Classification: 242/482.4

Cam-operated guide:

(under subclass 476.7) Subject matter including (1) a guide for the material moveable along the take-up and (2) a mechanism for generating the movement of the guide parallel to the axis of rotation of the take-up which mechanism includes two relatively moveable elements in sliding contact with each other such that the region of contact moves over the surface of at least one of the elements and the relative motion and contact between the elements compels the elements to move relative to each other with a non-rotary component.

(1) Note. Included in this subclass, for example, are mechanisms in which (1) the guide is moved by action of a threaded shaft on a non-rotating follower connected to the guide, (2) a rotary guide having a threaded hub is supported by and moved axially along a complementarily threaded stationary shaft, or (3) a non-rotating threaded shaft (cam) is moved axially by a pawl or pin rotating about the axis of the shaft and engaging the thread of the shaft.

480.9, for a mechanism for moving a guide including a sensor that follows a mark on a moving body in a manner analogous to the operation of a cam and follower.
