Japanese Patent JPS5342968
Kind Code:
A
Abstract:
For an automatic stitching apparatus of a type comprising at least one sewing machine having a stitching needle operable to perform a stitching operation to form an embroidery pattern on a fabric supported on an embroidery frame, a frame positioning device includes a holder for holding the frame in position relative to the stitching needle, X-axis and Y-axis drive mechanisms each including pulse responsive stepping motors mechanically connected to each other to provide an X-axis or Y-axis output drive necessary to move the frame in a predetermined direction to a given coordinate position, and first and second linkage mechanisms for transmitting the X-axis and Y-axis drives, respectively, to the frame holder. The stepping motor for each drive mechanism is connected in such a manner that the associated rotors are angularly offset from each other with respect to the axis of rotation of the rotors.
