ABSTRACT:
Apparatus for sensing the amount of fibers fed to a textile carding machine is disclosed which includes a feed roll (10) affixed to the frame of the carding machine for feeding fibers through a nip (26) between the feed roll and a feed plate (24). A rotational drive (B) is affixed at a free end of a feed roll shaft (40) in a free manner relative to the carding machine frame. Reaction force sensors (C) is mechanically coupled between rotational drive (B) and carding machine frame (12). Sensor means (C) senses the reaction forces on the rotational drive caused by the torque of feed roll (10) during feeding of fibrous mass (F) through nip (26). Sensor (C) includes a displaceable torque arm (50) and a sensor member (56). Sensor (56) senses the displacements of torque arm (50) which is affixed to rotational drive (B).
