A joystick allows memorization of a wide variety of stitching patterns on a self-learning basis. In this way, each stitching pattern may be programmed to have a variable number of stitches and the distance between them may be adjusted as desired.
This versatile machine also makes it possible to add or remove stitches at the end of the program and has a pick-up unit for loading the shoulder-pad onto a sliding clamp unit.
This clamp carries the pad into the sewing area for sewing purposes and takes it away from it when sewing has been completed. Once the shoulder-pad has been sewn, the thread is automatically cut and the shoulder-pad expelled from the machine.
All these operations are fully controlled by an electronic programmer.
Machine is equipped with a PFAFF 333 sewing machine with a 12 cm longer arm, complete with electronic stop and rotating speed converter for speed adjustment of the sewing head, software for saving programs and for transferring them to a PC.
It is also possible to sew some of the stitches within a program or to correct possible mistakes in the stitching by running the program at a slower speed than set (that is to say, the double-stitching at the beginning or end of a program, the double-stitching halfway through a program to pass from the right shoulder-pad to the left piece as well as some stitches within the program may be sewn at a slower speed for more accurate control).
Model PTX505-3A can sew with an axis movement of 95 mm. The sewing range of this machine is about 50 cm in length and about 27 cm in width.

– Output: 165 to 210 pairs of shoulder-pads per hour (this number may vary according to the kind of fabric used for the shoulder-pads, the thickness of the shoulder -pads, the type of thread used, the type of stitching pattern chosen, etc.)
The piece to be sewn is laid upon curved arm, inserted in two pins, after pressed START push button the pick-up unit load the shoulder-pad upon the clamp-unit with six clamps.
Thanks to the synchronized movement of the two axes, the shoulder-pad will be shifted in the sewing unit as the sewing program loaded. At the end of the sewing the thread cutter automatically cuts the thread and then air blowing unload the shoulder-pad behind the machine.
Note: Memorization of the sewing program does not require any skilled labour, as it takes place on a self-learning basis. Even an unskilled worker can memorize a program in 2 or 3 minutes and then immediately run it in automatic mode.
