(57) Abstract The pad stitch machine (10) which at least possesses the single needle stitch formation component of 1 sets is offered. As for this stitch formation component it includes the needle (36), and the looper (39) which in the separate head (35,38) are installed becoming independent in cross direction on the bridge (30) vis-a-vis the panel, it can move the head. As for the bridge (30) be able to move to longitudinal direction due to servo (32), as for the head (35,38) it can move on the bridge (30) to cross direction due to separate servo (43,44). The control control equipment (60) driving servo, pattern is done the chain stitch, the head is made to move to cross direction separately in order in addition to compensate deflecting the needle of cross direction. The drive of the needle and the looper can decide phase in order to compensate deflecting the needle of longitudinal direction. This control control equipment retains the data which is decided empirically, in addition the control signal and (or) responds to the sensor (81,82) and decision or estimates, and calculates the compensating value of deflecting the needle.
