Abstract
A sewing machine includes a sewing machine head, a sewing machine bed, a catching member, a cutwork device including a cutting needle having a blade, a cutting needle up-down movement mechanism moving the cutting needle up and down, and a switching mechanism configured to switch the catching member between a working position where the catching member is disposed at the cutting position at the side of the upper surface of the workpiece cloth and a retreat position retreated upward from the working position. The cutwork device is configured to form a cut in the workpiece cloth by the cutting needle at a cutting position from below the workpiece cloth. The switching mechanism is configured to switch a position of the catching member by the movement of the presser bar by the presser mechanism.
Claims5
A sewing machine comprising:
- a sewing machine head including a needle bar to which a sewing needle is attachable;
- a presser bar provided on the sewing machine head and having a lower end to which a presser foot configured to press a workpiece cloth is attachable;
- a presser mechanism provided in the sewing machine head and configured to move the presser bar between a raised position and a lowered position;
- a sewing machine bed having an upper surface on which the workpiece cloth is placed so that sewing may be performed on the workpiece cloth;
- a cutwork device provided on the sewing machine bed and including a cutting needle with a distal end having a blade and a cutting needle up-down movement mechanism moving the cutting needle up and down, the cutwork device being configured to form a cut in the workpiece cloth by the cutting needle at a cutting position from below the workpiece cloth, the cutting position being spaced a predetermined distance rearward from a needle location of the sewing needle on the sewing machine bed;
- a catching member configured to suppress upward floating of the workpiece cloth caused by the cutting needle during operation of the cutwork device;
- and
- a switching mechanism configured to switch the catching member between:
- (i) a working position where the catching member is disposed at the cutting position at the side of the upper surface of the workpiece cloth, and a retreat position retreated upwards from the working position, thereby switching a position of the catching member by a movement of the presser bar by the presser mechanism.
