Abstract
A method of providing for corrective laterally movement of a web of substrate material which is adapted to continuously move in a longitudinal direction through a vapor deposition processor without substantially buckling or tensioning either of the longitudinal edges thereof. The lateral displacement is accomplished without buckling or tensioning the edges of the web despite the fact that the web is magnetically urged into a generally planar path of travel as it moves through the deposition regions of the processor.
Claims12
A method adapted to provide for corrective lateral movement of a continuously and longitudinally moving web without buckling or tensioning either of the longitudinal edges thereof;
- said web being operatively disposed within a processor wherein material is vapor deposited thereonto in a deposition region thereof;
- the method including the steps of:
- providing means for urging the web into a substantially planar path of travel;
- movably mounting said web urging means for lateral displacement, whereby corrective lateral movement of the web relative to said longitudinal direction of travel may be achieved without buckling or tensioning the longitudinal edges thereof.
