Feed regulator of a sewing machine |
摘要 |
A feed regulator of a sewing machine capable of varying a seam length at the stitching operation employs a first driving device for swingably driving a feed regulating table by way of a link mechanism so that a feed dog can switch the feed direction, whereby a reverse stitching operation can be performed in the same way as the conventional feed regulator. The feed regulator also employs a link mechanism having one surface for retaining the projection of the link member having a slit, one surface of which can retain the projection of the link mechanism, and a second driving device for driving the link member, whereby the reverse stitching operation can be performed by second driving device in the arbitrary seam length.
