Abstract

PURPOSE:To easily stamp characters and patterns on a workpiece of fabric or paper by providing a needle bar stamping motion mechanism which brings a needle bar into a vertical reciprocating motion synchronizing with a stamping motion, and a mode changeover device which alternately changes the feed rate of a feeding device either to the feed rate for the sewing mode or the feed rate for the stamping mode. CONSTITUTION:When a needle 7 is taken off from a needle bar 6, a stamp 10 is attached on the lower end of the needle bar 6 by a stamp attachment 9, and the sewing mode is changed over to the stamping mode by a mode changeover switch 43, a fabric feed dog 12 is driven by a motor 15 at a higher speed for the stamping mode than that for the sewing mode, and the needle bar 6 is driven up and down by a motor 22 at a lower speed for the stamping mode than that for the sewing mode. As a result, the stamp 10 is stamped at regular intervals on a workpiece of fabric placed on a sewing machine table. The track of the stamp face is located in the middle between the upper face of a throat plate 11 and the surface of the workpiece of fabric so that the stamp face is certainly formed above the surface of the workpiece of fabric. Thereby, characters or patterns are easily stamped on the surface of the workpiece of fabric.
