Abstract
An embroidery sewing machine is provided for automatically driving an embroidery frame along X and Y axes. The bed of the machine is provided with a pair of parallel slots extending parallel to the X axis. A pair of carriages extend through said slots and the opposite ends of a single Y-axis guide rod which extends parallel to the Y-axis are secured to said carriages. A traveller is movably guided along the guide rod and one of said carriages is movably guided along a similar X-axis guide rod mounted below the bed. A pair of servo motors each having a drive roller are disposed under the bed and the carriages and traveller are each provided with a plurality of rollers. Wires extend around the rollers and rotation of one of the servo motors drives the carriages upon which the Y-axis guide rod is mounted along the X-axis guide rod. The rotation of the other servo motor causes the traveller to be driven in the Y-axis direction along the Y-axis guide rod. The embroidery frame is magnetically secured to the traveller for easy detachment. The servo motors operate under the control of a magnetic tape.
