Abstract
In the apparatus for drawing down knitted fabrics, a fixed position roller, a pressure roller and a drive for the rollers are located below mountainously opposed needle heads. The contact pressure between the rollers is controlled by a pivot mechanism including a cam driven by a motor and a spring connected to the cam and also connected to a pivot arm supporting the pressure roller. Rotation of the cam controls the spring force exerted on the pivot arm by the spring and thus controls movement of the pivot arm to lessen or increase contact pressure between the rollers.
