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.
