Image Number 2 for United States Patent #4068783.
A pressure plate is mounted on a vertical support for holding material. A material deflector is pivotally mounted with respect to the support and is adapted to deflect the material against the pressure plate. The pressure plate and the material deflector are formed with cooperating opposed faces for folding the material and with a needle guide for passage of a needle through the folds. A needle to which thread is fed, is held on a carrier and is movably mounted on the support to carry the needle into and out of the needle guide. A clamping device is arranged at the rear end of the needle guide to grasp the thread, and a cutter means is located at the front end of the needle guide to cut the thread. All of the elements are sequentially operated by a single actuator.
