ABSTRACT:
A web weight control system and method are disclosed wherein the actual weight of fibers supplied to a carding machine (36) are measured in a weight pan (20) or while moving on a conveyor (22) by a sensor (92). the supply roll (14) is controlled by computer (A) to supply a preset weight of fibers. The weighed fibers are supplied on an apron feed (22) to a pneumatic delivery system (28). The delivery of weighed fibers by apron feeder (22) may be adjusted by adjusting the speed of an apron feed roll (50a). This maintains a prescribed quantity or level of fiber in a fiber storage chute feed (32). Pressure sensed by a pressure gauge (52) is used to indicate quantity of fiber in chute feed (32) and pressure signal (53) is fed to computer (A) for control of delivery roll (50a). Card feed roll (62) which feeds fibers in the form of a batt (35) from chute feed (32) to the carding machine is controlled by computer (A) in synchronization with the speed of the carding machine as sensed by doffer roll (68). A preset web weight signal (48) is compared to an actual weight signal (46) representing the actual weight of fibers supplied. Any difference between is compensated for by adjustment of the operation of card feed roll (62), and adjustment of fiber supply roll (14).
