Abstract
A support carrying a cloth clamping member is moved in the X and Y directions of rectangular coordinates by a pair of pulse motors which are controlled by a control system to perform a profile sewing of a predetermined pattern. Reciprocation and stopping of the needle at the upper or lower dead center are also controlled by the control system which comprises a memory device for storing information regarding the numbers of pulses required to drive the pulse motors for moving the support in the X and Y directions by one sewing pitch and regarding repeated numbers of the sewing pitch in the X and Y directions, the pulses being produced by converting the profile into the amounts of movements in the X and Y directions, and information which commands the starting of the sewing operation, thread cutting, vertical reciprocation of the needle and the stopping of the needle at a upper or a lower dead center, in the form of binary codes and according to the predetermined sequences of the sewing operation.
