Abstract: The device for producing a uniform or profiled fleece or a fiber flock mat includes a material dispensing device which produces a fleece and a transport device for the further transport of the fleece. The device also includes a measuring device to determine a transverse profile and a longitudinal profile of the fleece by measuring the mass per unit area of the fleece across its width, and a profile-changing device for supplying individualized fibers or fiber flocks to the fleece. A control unit controls the profile-changing device on the basis of the results of the measuring device in such a way that the profile-changing device supplies the individualized fibers or fiber flocks section by section in a targeted manner. Thus, depending on the purpose of the application, a uniform fleece or a fleece with a nonuniform transverse profile or longitudinal profile can be produced.

Abstract: The feed device for scattering individualized fibers or fiber flocks comprises a scattering section, in which a driven feed roller and a driven opening roller cooperating with the feed roller are arranged. A dispensing device for storing and dispensing a fiber sliver is assigned to the feed roller in such a way that the feed roller pulls in the fiber sliver provided by the dispensing device, as a result of which the feed roller is fed with the fiber sliver or the fiber fleece strip. The opening roller is arranged adjacent to the feed roller in such a way that it opens up the fiber sliver pulled in by the feed roller to form individual fibers or fiber flocks and scatters them.

Abstract: A control system and method for controlling the rate (Y) of fiber input (24) into a delivery system (28) in response to sensed fiber quantity (56) is disclosed. The control system generates a step control signal (C,D) in response to first deviations about a prescribed fiber quantity condition (1 or 1,2). Deviations of small magnitude caused by various fiber delivery conditions, i.e. fiber opening, duct friction, etc., are taken into account without overreacting to the variation. In response to deviations outside the range of the first deviations, an integrated ramp signal (E, F or 128, 124) is produced which automatically seeks a new level of fiber input rate. Such deviations are normally caused by changes in system requirements such as the changing consumption and production requirements of an associated carding machine (48) to which fibers are fed from a chute feed (42).

Abstract: A control system for a textile chute feed is disclosed which includes first and second fiber quantity signals generators (A, B) which generate first and second fiber quantity signals (52, 54) proportional to sensed fiber volumes in chute (16). A fiber delivery weight signal generator (C) generates a delivery weight signal (60) proportional to the delivery weight of the fibers in the fiber batt (44). A delivery roll signal generator (D) generates a signal proportional to the rotational speed of the delivery roll (38). The fiber quantity signal (52) is integrated with a delivery roll signal (68) in a first controller device (70) to produce a feed roll control signal (71). The delivery weight signal (60) and the delivery roll signal (68) are integrated in a controller (74) to produce a control signal (75) which controls the oscillation of an oscillating fiber compaction plate (28). When the delivery weight signal (60) falls below a preset delivery weight signal (78), an airflow control signal (76) is produced by the controller (74) to control an air pump (22) and increase the air pressure in the formation chamber (16) to assist in compacting the fibers (42). When the rotation of the delivery roll (38) falls below a preset delivery roll signal (80), the feed roll control signal (71) is modified to rotate the feed roll (18) in an intermittent manner. When the second fiber quantity level represented by signal (54) is reached, the controller (70) terminates the rotation of the feed roll (18) until the fiber supply is reduced to a safe level.

Abstract: A loading station for forming a fiber mass for micronaire testing. The loading station has a hopper for receiving an unformed fiber mass. A forming chamber receives the unformed fiber mass from the hopper. The forming chamber includes a non-movable back wall and a non-movable bottom plate with ports formed therein. The ports draw an airflow from the hopper into the forming chamber. A selectively movable isolation plate isolates the forming chamber from the hopper, and a selectively movable horizontal forming wall horizontally compacts the fiber mass into a desired horizontal cross-section. A selectively movable vertical forming wall vertically compacts the fiber mass into a desired vertical cross-section. A selectively movable plunger presses axially along the shaped fiber mass.

Abstract: A throttle valve is provided within a discharge air duct located adjacent a fiber duct receiving a fiber laden air stream. The throttle valve cooperates with a stop in a lowered position to form a gap to allow a minimal air flow therethrough. In addition, a weight is provided on an arm attached to the throttle valve for pivoting therewith. The weight is disposed to counterbalance a substantial portion of the weight of the flap valve in the raised position of the valve so that the air flow maintains the valve in the open condition.
