ABSTRACT:
An apparatus and associated method for indexing a strip of sheet material in fixed amounts along the support surface of a table enable an instrument supported from a carriage spanning the support surface to work on the material in precisely controlled segments and utilize one or two stops fixed in the table and movable engagement means operatively associated with the stops to limit the advancement of the sheet material as the material is indexed. The apparatus includes a transport mechanism connected for movement with the engagement means, and the sheet material is coupled to the transport mechanism for movement along the support surface. The stops define limits of travel of the engagement means and the transport mechanism to precisely fix the amount of advancement of the sheet material between work positions. The indexing operation includes positioning the engagement means at one of the limits of travel, coupling the material to the transport mechanism, and moving the mechanism and material along the support surface until the engagement means reaches another limit of travel.
