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: A control unit maintains the fiber flock column in a feed chute at a set height. The control unit includes a row of light barriers located about a set height for emitting signals in response to interruption of the light barriers by fiber flock. An evaluation unit evaluates the signals to determine the actual height of the flock column and emits a control signal to adjust the feed rollers in the feed chute.

The latter has a licker-in, a feed table and a feed roller cooperating with one another in feeding the fiber lap to the licker-in; a drive motor connected to the feed roller; and an arrangement providing for a relative movement of the feed roller and the feed table towards or away from one another as a function of the thickness of the fiber material passing therebetween. There is further provided an excursion measuring device for generating signals representing the magnitude of the relative movement; and a control device connected to the excursion measuring device. The control device is connected to the drive motor for regulating the rpm of the feed roller as a function of the relative motion between feed roller and feed table. A delay device is connected between the excursion measuring device and the control device for delaying transmittal of signals from the excursion measuring device to the control device. An angular displacement measuring device for generating signals corresponding to an angular displacement of the feed roller is connected to the delay device for varying the extent of delay of transmittal of signals by the delay device as a function of the signals generated by the angular displacement measuring device.

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.
