Abstract: A system and method for preventing a deposition of a coating medium on at least a predetermined area of workpieces to be at least partially spray coated with the coating medium during a continuous spray coating operation. A covering arrangement is applied to the at least one predetermined area of the respective workpieces upon which the deposition of the coating medium is to be prevented prior to the continuous spray coating operation. The covering arrangement and the workpieces are simultaneously and synchronously advanced to the spray coating station so as to enable the continuous spray coating operation of the workpieces, with the predetermined areas covered by the covering arrangement being protected from deposition and/or contamination by the coating medium.

Abstract: The present invention provides an apparatus and method of forming tube, for example, muffler shells by the use of forming sheet over a mandrel by rolling a pair of symmetrical rollers from a point on the mandrel over an arcuate surface thereof to form the sheet thereof, the rolling being performed by roller means which are elongated to extend from the length of the mandrel and which are biased one towards the other with sufficient force to form the sheet as they are rolled over the surface of the mandrel.
