DEFINITION

Classification: 160/246

(under subclass 242) Roll type devices in which the only motion of the roll other than rotation about its own axis, is a straight line motion in the plane of the fabric that is unwound therefrom and in a direction at right angles to the axis of the roll.

SEE OR SEARCH THIS CLASS, SUBCLASS:

30, and 99+, for roll type devices mounted on sliding rigid closures.

242, for all other single types of translatory roll motion and for all rolls having two or more types of translating motion.

243+, for arrangements in which roll-translation is necessary

to cause the winding and unwinding operation.
