ABSTRACT:
A method of and apparatus for electronic scanning of control-fields of a control member on cylinder and straight bar knitting machines, in which the boundaries of the control-fields coincide with the boundaries of the needle pitches of the machine and electronic pulses are generated which are maintained during the run of the cam across a whole needle pitch or respectively across a number of whole needle pitches. The control pulses electronically amplified are fed to an obliquely positioned electromagnet or a piezoelectric movement-element having a wedge, arranged in a cam casing close to selector members, so that those selector members which coincide with a current pulse are moved away from the tips of inoperative members, a movement which arises both from the oblique guidance of the pole edges as well as the wedge. The tips of the members to be selected are removed so far from the tips of the inoperative members that before leaving the pole edges or before the magnetic pulse ceases at that point, a separator tip of a deflector connected with the cam passes behind the tips of each member thus preselected and thus secures a small separation, whereupon the deflector by its succeeding wedge drives the member towards the butt of the needle. Thus the tip of a foot of the needle moves behind the tip of the edge of the apex of a needle deflecton device, and the latter drives the needle into operation.
