Claims13
A sewing machine comprising:
- a sewing bed on which a plurality of cloth pieces are placed is a manner of being overlaid on each other;
- a felting needle;
- a woolen yarn guide provided at a lower end of a safety cover for covering the felting needle;
- and
- a device configured to raise and lower the felting needle toward the plurality of overlaid cloth pieces, wherein
- the woolen yarn guide is configured to guide a woolen yarn from a bobbin or a woolen yarn ball to a sewing location,
- the woolen yarn guide includes a groove extending in a horizontal direction parallel to the sewing bed and having opposing open ends such that the woolen yarn guided by the groove extends in the horizontal direction parallel to the sewing bed, and
- the device is configured to raise and lower the felting needle so that, in a state that the plurality of cloth pieces are overlaid on each other and the woolen yarn is put on the sewing location of the overlaid cloth pieces, needle felting in which the felting needle is thrusted into the plurality of cloth pieces and the woolen yarn is performed, and that fibers of the woolen yarn are caused to tangle with fibers of the plurality of cloth pieces and thereby the plurality of cloth pieces are sewn together.
