  • Sewing apparatus employing twin needles
    Patent number: 4043283
    Abstract: A sewing head employing twin needles for use with a material feed assembly at a sewing station, employing a linkage drive configuration enabling original rotary motion to be converted into linear rather than arcuate during formation of tacks. The same drive source is employed for both longitudinal and lateral motion, with a movable link added into the main feed link assembly. By means of a guide member, one portion of the main drive is confined to longitudinal motion only, while the other portion is free to go through the lateral motion separately. By employing an additional movable link and designing the main feed link as a two part link, while at the same time employing the same drive source for longitudinal and lateral motion, it is possible to achieve the necessary linear parallel motion. By the aforementioned arrangement, the drive link achieves linear motion and provides for a uniform tacking pattern for both needles.
