DEFINITION
Classification: 83/277
(under subclass 276) Device including opposed solid members arranged to hold frictionally a portion of the work to draw the work with them and thus present the work to the tool.
(1) Note. A gripper is a device comprising a plurality of opposed jaws or surface elements relatively movable to engage opposed surfaces of a workpiece and thereby apply sufficient force to enable advancement of the workpiece by said jaws or surfaces through their frictional engagement with said workpiece, i.e., in a direction substantially parallel to the surface elements or jaw faces.
