Abstract
Methods of and apparatus for manufacturing a knitted fabric from a strand of yarn by forming the yarn into series of interlaced loops. The apparatus includes an array of apertures through which sinusoidal loops of the strand are ejected sequentially, by a combination of an expanding stream of fluid and centrifugal force. As each loop is ejected through an aperture in the array, the loop is restrained on one side of the aperture by a reciprocation shoe and then lifted upwardly by the shoe while being held open by the shoe. A subsequent loop is then ejected through the first loop, and the shoe is moved downwardly to restrain the subsequent loop and to release the first loop. As the shoe moves downwardly, the first loop is pulled through the aperture by a reciprocating hook which engages the foot of the first loop on the other side of the aperture. The subsequent loop is then lifted as the shoe passes through the loop in preparation to receive another loop, so that the process of interlacing loops is continued.
