Latest Patents
Roger E. Lemay holds a patent for a "Method and apparatus for controlling an automatic bar tacking machine." This invention relates to an automatic sewing machine where the workpiece is moved under the sewing head by a clamp driven by stepping motors along two coordinate axes through a predetermined pattern. The stepping motors are connected to the workpiece clamp through a non-linear linkage assembly. The motors are controlled by a coded Programmable Read Only Memory (PROM), which generates signals in timed relation to the operation of the sewing machine. The PROM is coded by digitizing the stitch coordinates of the predetermined pattern and modifying each coordinate value to compensate for the non-linearity of the linkage system.
