ABSTRACT:
A feeding device of a wide sewing material comprises a first belt conveyer unit provided on a supporting member vertically driven by a first elevating unit, a first base plate vertically driven by a second elevating unit provided on the supporting member, a horizontally driving unit for horizontally driving a second base plate and a second belt conveyer unit which is supported by the second base plate and is arranged on the side of the edge portion to be sewn of the wide sewing material in parallel therewith and which is driven to rotate by a rotary device. Since the feeding device can secure a large space from the edge portion by retracting the second belt conveyer units, next operation can be performed with ease. As a result, it is possible to perform the feeding and sewing of a wide sewing material, which is difficult to work at the edge portion thereof automatically, with accuracy and efficiency.
