摘要： A computer controlled pattern stitching machine includes input means 30 for supplying BCD X and Y-axis scaling signals to enlarge or contract a pattern to be sewn, control means 28 including a CPU 58, a RAM 60 and a memory 62, and drive means 32 including X and Y-axis stepping motors for moving a gripped fabric relative to a needle bar in response to signals from the control means. The stepping motors 42, 44 drive respective timing belts 66, 78, and belt 66 carries orthogonally mounted X and Y-axis rail members 70, 84 on which a cloth holding device 68 is secured.

摘要： A pattern sewing machine comprises a cloth feeding mechanism for moving a piece of cloth; a sewing machine mechanism driven independently of the cloth feeding mechanism; a memory element in which control data including pattern data and sewing machine drive data are stored; a control circuit for synchronously driving the cloth feeding mechanism and the sewing machine mechanism according to the control data stored in the memory element; a temporary stop instruction for stopping the sewing machine mechanism during sewing; and a minute movement instruction for driving the cloth feeding mechanism only, the control circuit having a function of driving the cloth feeding mechanism according to the minute movement instruction after the cloth feeding mechanism has been stopped by the temporary stop instruction, and a function of driving the cloth feeding mechanism according to the pattern data thereafter.

摘要： 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.
