Abstract: A flock transportation device with a switching device for the flock stream includes a monitoring apparatus which detects the degree of contamination of the fiber material. The monitoring apparatus includes an evaluation device which determines the cleaning requirements of the detected material and which controls the switching device accordingly. A flock processing installation is contemplated with several transportation paths which comprise different treatment characteristics. Additionally, the flock processing installation can be controlled by way of a central control systems.

Abstract: A flock extraction apparatus includes a pair of ducts which extend along a track for conveying fiber flock and a diverter chamber at one end of the ducts for directing the flock into one or the other of a pair of transport ducts extending from the diverter chamber. Plates are used to block communication between the diverter chamber and the respective transport ducts as well as to sub-divide the diverter chamber for communication with a respective duct extending along the track.

Abstract: The flock delivery system employs a microcomputer with a storage cell for each marker and a storage cell for each stretch of path (containing one or more bale groups) between the markers. The control system is conditional selectively to "permit" or "inhibit" extraction of flocks from bales in each block individually. Various flock bending combinations can be obtained from time-to-time by programming of the control system.

Abstract: The fiber processing installation monitors the operation of a discontinuously operating stop/go stage to obtain an actual value signal corresponding to the ratio of operative time to inoperative time as well as the total production of a continuously operating downstream stage, such as a card room, to establish a set value signal. A deviation of the actual value from the set value provides a control signal to adjust the ratio of operative time to inoperative time of the upstream stage so as to maintain the total production of the installation constant.
