ABSTRACT:
A needle selection control apparatus for circular pattern knitting machines which controls the timing of selection of a series of needles mounted on a needle cylinder. Needle synchronizing signals produced by sensor means which senses each cylinder needle rotating with said needle cylinder are electrically processed so that input pulse signals are formed whose phases have angles of lead controlled by the apparatus in accordance with the number of revolutions of the needle cylinder, and the input pulse signals are also electrically processed so as to remove unnecessary contents of the signals due to the eccentricity of the needle cylinder therefrom. The input pulse signals thus obtained are supplied to needle selector means for actuating the same at very high rotating speeds of the cylinder without error.
