Abstract
An industrial automatic pattern stitching sewing machine in which the speed of a cloth holder feeding cloth at a sewing needle is limited to a predetermined maximum speed in any direction so that the movement of the cloth holder is always in synchronization with that of the sewing needle. With this arrangement, pattern irregularities and jamming caused by nonsynchronization between the cloth holder and sewing needle are eliminated. Pulse numbers from a stored stitching pattern are examined to determine which of the X and Y pulse numbers is the larger. The larger of these is compared with a stored maximum value. If the larger number is less than the stored value, the two pulse numbers are outputted directly. Otherwise, at least one of them is limited to the maximum value.
