Abstract
A numerically controlled stitching machine tool comprises a head and a ta movable in relation to each other along two coordinate axes. The head is provided with a stitching needle and an optical follower placed in an invariable position in relation to the needle and receives the image of a drawing of the pattern when the drawing is placed on the table. The machine comprises, for each coordinate axis, a motor for moving the head and the table in relation to each other along that axis, transducer means for supplying an electrical signal whose amplitude depends on the movement along this axis, for A/D conversion and non-volatile storage, means for controlling the motor from the stored signals bringing into action said transducer and conversion means.
