ABSTRACT:
An apparatus as disclosed for controlling the distribution of fibers in a fiber felt forming process, which comprises a guide duct through which a gas current with felt fibers entrained is directed. The gas passes through a perforated conveyor, which retains the fibers.
The duct is caused to oscillate by a connecting rod affixed to the guide duct and a rotary element by universal joints at either end, connection being effected by cardans, by which the rotary element entrains the connecting rod in its rotary movement. By moving the axis of rotation of the rotary element away from the center of the guide duct/connecting rod joint, an oscillating movement is imparted to the guide duct. The entire apparatus, including a motor for inducing rotary movement may be caused to undergo translational movement by a pair of opposed hydraulic jacks, the operation of which may alter the median direction of the movement of the oscillating guide duct.
The apparatus as disclosed provides for automated movement and correction during operation of the device, providing better control over the distribution of fibers.
