Abstract

A flat-bed knitting machine has been described which is provided with needle sinkers arranged in a knitting cam system of a cam box carriage featuring several cams adjustable by means of stepping motors and having an electronic control unit, which features a storage device for controlling the stepping motors. In order to make the knitting density variable not only in the longitudinal direction, i.e. uniformly as a whole, row by row, but also in the transverse direction across the knitting with knitting machines of this type, the stepping motors are controlled by the storage device, one motor of which, in each case, is associated with a pair of needle sinkers consisting of preceding and trailing needle sinkers during the stroke of the cam box carriage and in synchronism with the individual needles.
