An apparatus for automatically sewing a succession of fabric pieces to a continuous slide fastener chain comprises a sewing machine for feeding and sewing the fabric pieces and slide fastener chain together; a guiding apparatus disposed upstream of the sewing machine and including a pair of opposed guide rollers urged towards each other with the slide fastener chain interposed therebetween so as to be driven via the slide fastener chain by the sewing machine while guiding the slide fastener chain towards the sewing machine; and a feeding apparatus disposed between the guiding apparatus and the sewing machine and including a pair of opposed feed rollers urged towards each other so as to convergently place therebetween the slide fastener chain into superimposed relation to the fabric pieces and to feed the fabric pieces with the slide fastener chain thus superimposed thereon to the sewing machine. One feed roller of the two feed rollers of the feeding apparatus which the fabric pieces ride on and one guide roller of the guide rollers of guiding apparatus are so linked as to rotate with each other.
