Definitions

  • a machine of this type is, for example, described in the Applicants Belgian patents Nos. 675,851 and The rib ends knitted on such a machine are intended for jersy machines. As it is sometimes desirable, for reasons of extensibility or elasticity, to knit the rib ends on a larger width than that of the jersey panels, to which they must be fitted, it is necessary to bring the last row of each rib end to the exact width of the said jersey panels, whilst respecting the gauge.
  • the object of the present invention is to mechanize the doubling process.
  • a process which, after a rib end has been knitted on some of the needles of a machine of the considered type, consists of simultaneously transferring some of the loops of one needle bed on to the free needles of the other needle bed; of racking one needle bed in relation to the other; of then transferring the remaining loops from oneneedle bed on to the al-' ready laden needles of the other; of simultaneously picking up all the loops on one needle bed in a manner known per se; of bringing closer together the groups of loops thus picked up, so as to have a distance of one needle spacing between any two varied stitches, and of needle bed 2 and carries them with the rest of the rib end, of course, opposite to the teeth of magazine comb 8.
  • the transferdevice 9 passes the said loops from reed 7 to reed 8.
  • a l X l fabric is first knitted as shown in FIG. 2.
  • the loaded needles are divided into groups of seven, separated each time by two needle spacings the last needle of each group bearing two loops.
  • high heel needles are used for loops concerned with the first transfer and low heel needles for the other loops. Opposite the low heel neephases;
  • arib' end machine of the type under consideration comprises, per knitting headza front needle bed 1 and a'rear needle bed 2; two needle raising devices 3 and 4 comprising U-shaped needle catch bars 5 and 6 intended to cover the needle heels of the corresponding needle bed, to bring theseneedles into high or low position; a transfer reed 7; a magazine reed 8 and a transfer device -9. Thisunit-is'well-known.
  • raising device 3 in its first upward movement, raising device 3 .carries along all the high heel needles, whereas in its second upward movement, after racking the front needle bed, it will carry along all the needles, since grooves ents no difficulty for a craftsman.
  • each of-these, blocks has seven teeth 13. These blocks 12 are guided between two flats l4 and 15.
  • each block 12 On its lower side,-each block 12 has two transversal 1 grooves 18 and 19.
  • blocks 12 separate to a distance such that there is a space equal to two needle spacings between two groups of neighbouring teeth, whilst a movement in the opposite direction reduces this space to one needle spacing.
  • a process for making rib ends on a double needle bed rib and knitting machine and transferring the rib ends onto a magazine reed having a smaller width than said rib ends as knit by means of a variable width transfer reed comprising knitting a rib end on selected needle bed needles, simulatneously transferring groups of loops of one needle bed onto the free needles of the other needle bed; racking said one needle bed in relation to said other needle bed at least one needle spacing; transferring the remaining loops from said one needle bed onto the already laden needles of said other needle bed to thereby make varied loops in said groups 3 5 of loops; simultaneously picking up all the loops from said one needle bed in a manner known per se by said transfer reed; bringing closer together on said transfer reed the said groups of loops thus picked up until a distance of one needle spacing exists between any two varied loops; and transferring all the loops thus picked up and brought closer together onto the said magazine reed from said transfer reed in
  • a rib end knitting machine having a double needle bed, means for transferring selected loops of formed rib ends of one needle bed to the other needle bed to form groups of loops; means for racking said one needle bed with respect to said other needle bed at least one needle spacing and transferring the remaining loops on said one needle bed to the already laden needles of said other needle bed to thereby form at least one varied loop in each of said groups of loops on said other needle bed; said groups of loops being separated by more than one needle spacing between said varied loops; an adjustable width transfer reed for simultaneously picking up said groups of loops from said other needle bed, said transferreed having means for adjusting its width whereby the spacings between said groups of loops may each be reduced to a single needle spacing; a magazine reed of less width than said rib ends as knitted; and means for transferring said groups of loops to said magazine reed, whereby said groups of loops may be transferred to said magazine reed after said transfer reed has been adjusted to leave only single
  • said adjustable width transfer reed comprises a plurality of teeth holding blocks, and means for moving said blocks with respect to each other to at least a first position where a distance equal to a single needle spacing exists between all of said blocks, and to at least a second position where a spacing equal to some multiple of said needle spacing exists between said blocks, said blocks further each having groups of teeth corresponding in number to the number of loops in each of said groups of loops, and each of said teeth in said groups of teeth being spaced one needle spacing apart.
  • adjustable width transfer reed includes means interconnecting said blocks for causing all said blocks to move together or further apart substantially simultaneously when the width of said transfer reed is adjusted.
