Claims

[Scope of Claim for Utility Model Registration] After the sewing machine is driven in connection with the starting operation and a predetermined number of stitches are formed within the frame of a frame-shaped presser foot while moving the fabric, the sewing machine is operated in connection with the completion of stitch formation. In a cycle sewing machine that performs cycle sewing, a presser foot is supported at the tip, and the presser foot is movable up and down between a lowered position where it touches the fabric on the sewing machine bed and a raised position where it is separated by the force of the writing force, and is always elastic to the raised position. A presser arm that receives force, an operating position that is linked to the main shaft of the sewing machine and can move up and down in synchronization with the up and down movement of the needle so that it touches and separates from the cloth on the sewing machine bed at the point near the needle drop, and an arm that is separated above it. The auxiliary presser is movable to the working position and always receives an elastic force to the non-working position, and the auxiliary presser is arranged between the main shaft and the auxiliary presser so as to connect the main shaft and the auxiliary presser in the working position of the auxiliary presser and to disconnect them in the non-working position. a releasing means, an electromagnetic means that is energized in connection with the starting operation and deenergized in connection with the completion of stitch formation, and an action that resists each elastic force on the presser arm and the auxiliary presser in connection with the energization of the electromagnetic means. A presser foot device for a cycle sewing machine, comprising: an action means for applying a force to move to a lowered position and an action position, and releasing the action force in connection with deenergization.
