(under the class definition) Device including means to advance the workpiece at an angle to the direction of motion of the tool(s) during the actuation of the selected tool(s).
(1) Note. This subclass does not include patent for a device wherein the only movement of the work is incidental to the
approach of one tool to its cooperating tool, (e.g., work carried by a moving die plate against fixed punches).
(2) Note. This subclass contains, for example, patents directed to means for recording the actuations of piano keys by selectively punching a moving paper strip.
