ABSTRACT:
A large scale X-Y plotting table is provided with electro-pneumatically controlled clamping bars at opposite ends, with roller-formed troughs adjacent thereto for supporting supply and take-up rolls of sail cloth or the like. The clamping bars are coupled to foot operated switches for locking the bars alternatively in the clamping or releasing position. Index marks plotted at the fabric edge and an index line on the table, as well as a longitudinal fence, facilitate indexing the fabric between adjacent plotting fields corresponding to window fields of the associated CAD equipment.
