Multiple pattern sewing machine |
摘要 |
A control apparatus for a multiple pattern sewing machine. Included in the sewing machine are a means for controlling the displacement of a feed mechanism for feeding a cloth and a means for controlling the displacement of a bight mechanism for swinging a sewing needle in the direction crossing the cloth feeding direction. A plurality of switching devices are provided for selectively coupling to the feed control means a plurality of different amplitude reference signals for controlling the feed mechanism. A plurality of switching devices are provided for selectively coupling to the bight control means a plurality of different amplitude reference signals for controlling the bight mechanism. Counter means, which are responsive to a timing signal generated for each stitch in the pattern, are provided for making a stepping operation for selectively rendering conductive the switching devices of the feed switching means and the bight switching means for each stepping operation.
