the channel 46 the wedge 28a is then retracted and in this way acting on the fins 48 causes resilient divergence of the projecting portions of the yarn supply members 30s and 30d as shown in fig1 and 13 the extensions 52 are thereby moved outside the needles 4s 4d considered as a pair and thus the outside of the gap formed by the needles in the meanwhile according to a selection desired the needles can be raised completely or partially and thus in the embodiment illustrated both the needles 4s and 4d or only one thereof may have been raised this depending upon the article to be produced in the diverged configuration of the yarn supply members they may be retracted with the extensions 52 on the outside of the pair of needles 4s and 4d by means of the ramps 42y or 44y while simultaneously the wedge 28a is retracted by the corresponding ramp of the channel 46 consequently a yarn tv1 and or tv2 which is carried by the members 50 54 of a yarn supply member 30s or 30d is brought in close proximity to the needle which has been raised such as the needle 4s of fig1 to 15 above the latch of the raised needles the yarns tv1 and or tv2 remain engaged by the needles even if the latter come down and then go up without being cleared while these needles all take up a knitting yarn such as m1 the needles in particular may be relevelled.
