ABSTRACT:
A circular knitting machine having a device for electronically issuing a pattern-forming command is provided with a needle selection verification pulse detector. The needle selection verification pulse detector produces a needle selection verification pulse B.sub.1 in response to a needle-selecting coil exciting-voltage B affected by a pulse induced in a needle-selecting coil and to a needle-selecting coil command voltage A not affected by the pulse thus induced when a needle selector in a needle-selecting system moves. When the presence or absence of the command voltage A does not coincide with the presence or absence of the verification pulse B.sub.1 respectively, occurrence of a knitting error is immediately detected.
