ABSTRACT:
In an automatic pick-up sewing system for curved edges of a fabric piece such as an outer pocket on clothing such as a jacket, the clothing kept in a horizontal state with the fabric piece pressed against a sewing needle is displaced two dimensionally during pick-up sewing as programmed under computer control while the sewing needle is driven for concurrent horizontal rotation so that the point of the sewing needle should always be directed in tangential directions of a sewing line on the fabric piece. Beautiful pick-up sewing is achieved quite at high efficiency without any need for highly skilled manual operation.
