ABSTRACT:
A sewing machine includes a base, a sewing device installed on this base to sew material, and a pair of material setting/transfer assemblies provided on the base. Each material setting/transfer assembly comprises a sewing portion setting mechanism fixed on the base which is able to position portions of the material to be sewn including tucking ends; a transfer mechanism mounted on the base movably between this sewing portion setting mechanism and the sewing device; and a tuck-in mechanism movably attached on the base for approaching to and retreating from the sewing portion setting mechanism. The tuck-in mechanism serves to fold the tucking ends in for forming the portions to be sewn into tucked sewing portions in cooperation with the sewing portion setting mechanism, so that the transfer mechanism continues to hold these tucked sewing portions together with the tuck-in mechanism until, at least, the tucked sewing portions are released from the sewing portion setting mechanism for enabling the transfer mechanism to carry the tucked sewing portions to the sewing device.
