Abstract: An upstanding knitting cylinder carries a multiplicity of needle jacks on its circumference. In order to selectively move the needle jacks up and down on the knitting cylinder during the rotation thereof, a vertical row of selector fingers capable of engagement with butts on the needle jacks are rigidly mounted to respective sleeves which in turn are rotatably mounted on fixed horizontal shafts disposed in parallel spaced relation to one another in a vertical plane. Disposed opposite the respective sleeves on the fixed shafts are several pairs of electromagnet assemblies which are arranged in two diagonal rows in order to reduce the vertical dimension of the needle selector. An armature secured to each sleeve is held opposite each pair of electromagnet assemblies so as to be alternately attracted thereby, with the consequent bidirectional rotation of the sleeves and, therefore, the pivotal motion of the selector fingers to engage and disengage the needle jack butts.

Abstract: A machine for progressively roughing marginal portions of shoe bottoms comprising a shoe support (18) having toe support means (470) and a heel support arrangement including two sets of clamps (390, 392), one set (392) of which serves also as sensing means for sensing, by engagement with an off-set portion of the shoe last whether the shoe thus supported is a left or a right. An inductance sensing device (610) associated with the second set of clamps (392) supplies a signal to control means of the machine, the signal being dependent upon whether the shoe is a left or a right. The control means ensures that, in the operation of the machine, a roughing operation is carried out on the shoe bottom in such a manner that the inside waist region of the shoe bottom is traversed always in the same directiion, regardless of whether the shoe is a left or a right (and of course similarly the outside waist region is consistently operated upon).

Abstract: Process for making a sock of the type with two layers. A first course knitted by the needles, and corresponding to the end of the tip of a first layer, is transferred onto the central transfer plate of the machine where it is maintained in standby. Knitting of the first layer is continued, from the tip to the mock-rib edges. Then knitting is continued from the mock-rib edges of the second layer up to the tip, the knitted tubular structure being constantly suspended, by one (circular) end, from the central transfer plate and, by the other circular end, from the needle cylinder in the course of work, thus shaping the two concentric layers engaged in one another. The initial course in standby on the plate is transferred to the needles of the cylinder to effect join of the two layers to form one sole terminal layer.

Abstract: The method of production of a double knit fabric for sports garment, namely sweater and hockey includes repeating a pattern of predetermined courses containing wales of consecutive selected groups of tuck and welt stitches to form holes in and throughout the knitted fabric. The pattern is repeated to provide a fabric with a considerable number of holes aligned in a predetermined geometrical arrangement. The method making holes resides in knitting one to two adjacent wales on the cylinder by a combination of many tuck stitches in consecutive courses with welt and knit stitches associated thereto in the courses preceding and following same tuck stitches. The fabric can be knitted in uniform color but may also be knitted to provide horizontal color bands of various widths and colors depending on the yarn color and the number of consecutive courses with a different color of yarn and the desired color arrangements.
