ABSTRACT:
A mattress support table with conveyor receives a mattress from a feed conveyor. The support table then indexes to a central position whereat a sewing machine passes around the periphery to sew the uppermost fabric panel to the border panel. The table then indexes to the exit conveyor and discharges the sewn mattress to be turned over, whereupon the mattress is returned to the support table to sew a bottom fabric panel. The table conveyor may be moved with a sewing machine so that an edge of the mattress is presented to the table periphery thereby allowing the sewing machine access to the edge.
