Abstract
Method and apparatus for processing textile materials and, in particular, controlling the density of fiber in a carding system. A fiber feeder is provided which includes a blower and an oscillating plate, both of which act to compress fiber collected in the chute of the fiber feeder. A first sensing device is utilized at the discharge of the fiber feeder to sense the density of the batt being fed therefrom to a card, and a second sensing device is utilized at the trumpet of the card to sense the density of the fiber which forms the sliver in such trumpet. Control means is provided to regulate the operating speed of the blower and the oscillating plate in response to the signals generated by the first and second sensing devices.
