Abstract
A control system for use in textile processing equipment including a card and a chute feed delivering a batt of fiber thereto. The operating speed of the card is sensed to generate a signal that is used to drive the motor for the oscillating densification plate and the feed roll of the chute feed at speeds having a predetermined ratio of the operating speed of the card. The weight of the batt formed by the chute feed is sensed and a signal is generated in proportion to the sensed weight, and this signal is used to override the primary drive for the oscillating plate and thereby vary the ratio between the operating speed of the card and speed of oscillation of the plate. The chute feed includes a device for sensing the level of accumulated fiber in the chute feed, and this device generates a signal that is utilized to override the primary drive for the feed roll of the chute feed and thereby vary the ratio between the operating speed of the card and the speed of such feed roll. In another embodiment, the 'on-off' operating condition of the card is sensed, and the feed roll and oscillating plate are operated at a predetermined speed in response to the 'on' condition of the card being sensed. The signal generated by the batt-weight sensing means is then used to vary the predetermined speeds of the feed roll and the oscillating plate.
