  • Microprocessor-assisted sewing machine control equipment
    Patent number: 6647908
    Abstract: A microprocessor-assisted sewing machine control equipment is flexibly applicable for controlling the sewing machine driving motor and further electric motors which are controlled independently of or in dependence on the rotary position. To this end, a control system is allocated to each electric motor, comprising an open-loop control unit for rotary-position-independent controlling, a closed-loop control unit for controlling the electric motor in dependence on the rotary position, and a selection unit. The selection unit couples for control either the closed-loop control unit or the open-loop control unit with the electric motor, depending on whether the electric motor is controlled by closed-loop control in dependence on the rotary position or by open-loop control independently of the rotary position.

  • Method of sewing supplementary parts on a workpiece
    Patent number: 6637358
    Abstract: In a method of sewing at least one supplementary part on a workpiece, a workpiece identification is fed into a computer and a program is activated thereby, which indicates, on the display screen, the respective supplementary part that is to be sewn on next, and which permits a sewing operation only when the supplementary part is placed on in a correct arrangement and, possibly, in the correct position on the workpiece.
