Abstract
A needle selecting system having a pair of rockable selector jacks mounted in tandem in each needle groove below the needle retained therein. The adjacent ends of the jacks are formed with butts engageable selectively by projecting elements of a pattern wheel mounted adjacent the needle cylinder, which causes the selector jacks to engage in appropriate paths in the cam system, thus displacing the needle. The cam system is arranged with surfaces which push back the selector jacks into their original position, which surfaces are formed in front of the clearing point for each yarn feed.
Claims3
A knitting machine having multiple yarn feeds, a needle cylinder in which a plurality of needles are mounted in respective grooves, each displaceable into knitting positions in cooperation with a sinker or opposed needle by a cooperating cam system, and a needle selecting system, said needle selecting system comprising a pair of rockable selector jacks mounted in tandem in each needle groove below the needle retained therein, control butts formed on the adjacent ends of each of said selector jacks of said pair, a patterning wheel mounted adjacent the needle cylinder having projecting elements engageable selectively with said butts which cause the selector jacks to engage in appropriate paths of the cam system and be moved to displace the needle, said cam system having retracting surfaces which push back the selected selector jacks into their original position formed in front of the clearing point for each yarn feed.
