Cutting device for creating a slit opening for a buttonhole |
摘要 |
A cutting device in a sewing machine for creating a slit opening for a buttonhole in a workpiece. First and second tool parts are spaced apart from each other in an open position and can be brought together in a closed position. One tool part has a block and the other tool part has a cutting edge. The block is formed in the shape of a strip, is accepted into a slit located on the sewing machine and is attached there with a clamping device. A slit opening can be created in a workpiece in a block-cutting mode by the cutting edge and the block. The cutting device can also be used for making a slit opening in a workpiece in a slit-cutting mode by removing the block and providing a different cutting edge, which can be performed in a simple manner.
