(under the class definition) Coating apparatus combined with means to apply a stress tending to cause elongation of the work.
(1) Note. Here may be found, for example, patents for tentering cloth during the coating operation, and also means for maintaining a web under tension as it passes through the coating device.
(2) Note. Mere means for pulling a web through a coating 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 web, and such devices will be found in appropriate subclasses below, for handling web or strand form work.
