Latest Patents
Hagiwara holds a patent for an electronic sewing machine. This machine features a rotatable shaft that operates a stitch forming device. It includes a feed dog for feeding fabric to be sewn and a needle for forming stitches in the fabric. The machine is equipped with a first electronic memory that stores stitch control data, including needle position control data for different patterns. It also has a pattern selecting element that reads the first memory stitch control data for a selected pattern. Additionally, the machine comprises a timing element that operates synchronously with the shaft to produce a timing signal for progressively reading the stitch control data from the first memory.
The sewing machine also features a stitch mode changing switch element that determines the elongation rate of a selected pattern in the fabric feeding direction. A second memory element temporarily stores designated stitch control data from the first memory element. Furthermore, a counter element counts the ordinals of the stitches of the selected pattern in relation to the timing signals and the pattern elongation rate. This allows for the designation of the pattern elongation rate and the stitch control data to be stored into the second memory element progressively during the formation of the stitches. Lastly, a calculating element works with the counter element to produce second stitches between the first stitches formed by the stitch control data.
