DEFINITION

Classification: 226/162

(under subclass 158) Device provided with means for driving a clamping portion of the material-mover into contact with the material.

(1) Note. In this and indented subclasses are patents for devices which clearly disclose that the material-advancing elements(s) move into and out of contact with the material. Thus, a patent disclosing a spring-biased gripping element will be placed herein only if it clearly discloses and claims means for moving the element out of material-engaging position.
