ABSTRACT:
An apparatus for securing the free ends of an elongated strip of flexible material to form a band, such as an elastic band for various types of apparel. The machine includes a securing station, such as a sewing station including a sewing machine, and an apparatus for drawing a strip of flexible material longitudinally beneath the securing station in a measuring path. A measuring device deflects a predetermined length of the strip downward away from the measuring path to form a measured open loop. A knife mechanism cuts the trailing end portion of the loop. Loading and clamping mechanisms position the free ends of the loop in the securing station for attachment, such as by stitching. An ejection mechanism withdraws the finished loop from the sewing station for discharge. The measuring device is provided with adjustment means for adjusting the length of the deflected loop and therefore the size of the completed band. The apparatus preferably includes an extraction mechanism for withdrawing the clamped, measured loop from the measuring path while the loop is being secured to permit initiation of the next measuring cycle.
