A fiber level sensing device is provided adjacent the area of wall perforations to control the flow of fibers from the opening roller to the chute.

Fiber feeding apparatus with fiber leveling means

Method and apparatus for feeding, weighing and releasing a predetermined quantity of fiber in reoccurring cycles for use in a fiber blending operation or the like whereby the quantity of fiber released in each cycle is maintained at an essentially constant and preselected level, which includes means for sensing the actual weight of fiber dumped from a weigh pan or container, comparing such weight with a constant preset desired weight setting, and varying the weight of fiber delivered during the next cycle to compensate for any differences between the preset weight and the actual weight dumped during the preceding cycle.

Method and apparatus for feeding, weighing and releasing fiber

A chute feed having a chute formed in part by an upper perforated wall portion and a lower oscillating wall portion. Two compartments are formed adjacent the chute and are separated therefrom by the upper and lower wall portions, and a divider wall is disposed to extend from the front of the chute feed to a location between the upper and lower edges of the upper perforated wall portion, such divider wall separating the two compartments and permitting the compartments to be exposed to upper and lower parts of the perforated wall portion, respectively. A blower having an inlet connected to a location outside the chute feed directs a path of air around the opening roller of the chute feed, through the perforated wall portion, and into the upper compartment where the air, and any dust or micro-dust entrained therein is sucked from the upper compartment by an air outlet conduit adapted to be connected to the vacuum of the extractor associated with the card being fed by the chute feed, whereby the air flow serves to level the fiber in the chute and also to remove and exhaust dust and micro-dust from the fiber. The lower compartment causes air to be forced into the chute through the lower part of the perforated wall portion during movement of the oscillating wall portion in its non-densifying direction, such air acting to assist in compacting the fiber in the chute.

Fiber feeding apparatus with controlled air flow

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.

Control system for fiber processing apparatus

Apparatus for removing fiber portions from a selected plurality of bales and delivering the fiber to a receiver, such apparatus including a head that is lowered into contact with the top surface of such bales to grasp fibers therefrom. A control system is provided which generates a signal when the head has traveled a predetermined vertical distance toward a bale, and the signal is used to vary the sequence of pick-up or the amount of fiber picked up, from the plurality of bales to assure that the plurality of bales are maintained at substantially even heights during the sequential pick-up of fiber therefrom.
