ABSTRACT:
A carding machine drive having an instantaneous braking system is illustrated wherein the driven main cylinder and carding components driven therefrom may be stopped instantaneously in about three seconds or less avoiding breakage of the web. A disk element is employed having opposed braking surfaces which are clampingly engaged by caliper means which are fixed to the card frame. The disk element has fixed connection and transverse alignment concentrically with the main cylinder. By driving carding components including the doffer directly from the main cylinder, simultaneous stopping thereof may be achieved. By utilizing conductor bars on component covers removal thereof automatically institutes braking.
