(under subclass 349) Apparatus combined with means subjecting the work to a stress causing or tending to cause extension of the work.
(1) Note. Mere means for pulling a workpiece through a laminating device against the normal resistance of the device are not considered tensioning devices unless some specific means are present to place a drag on the workpiece and such devices may be found in appropriate subclasses below for handling the particular work.
