  • Patent number: 4103636
    Abstract: Apparatus for making a seam from two threads, each thread being formed into bridging loops and prone loops, each prone loop of one thread embracing a doubled portion between two bridging loops of the other thread, such doubled portions forming the prone loops. The apparatus has opposed sewing-machine-type needles which move together and apart, crossing a reference plane between the needles in a pattern whereby a loop between the eye of one needle and the previously made seam, is penetrated when the first needle starts to retreat from its furthermost excursion past the reference plane, by the other needle during its approach to the reference plane. The needles of a pair are slightly staggered laterally so that they pass one another, preferably with light contact, during loop penetration.The example relates to a seam which is made upon a base fabric and in which the bridging loops of both threads are held slack to form pile loops by means of loopers.

  • Patent number: 4100814
    Abstract: A mechanism is described for effecting movement of an object, article or device in a closed loop planar path while maintaining the major axis of the object, article or device in substantially fixed attitude in the execution of at least an appreciable portion of the path, the mechanism comprising a six-bar linkage the dimensions of which are derived from a four-bar linkage to ensure the fixed attitude motion during motion through at least the appreciable portion of the closed loop path.
