Abstract: To optimize the cleaning of cotton in a spinning milk, there is entered into a control original data concerning fiber characteristics and proportions of different types of contamination inherent to the origin of fiber cotton bales. Also there is entered into the control a desired degree of cleaning and a throughput quantity of the carded fiber sliver. The control delivers predetermined control signals based upon the entered original data, the throughput quantity of the carded sliver and the desired degree of cleaning. These control signals set adjustable operating members governing the rate of opening of the cotton bales by bale opening machines, the degree of cleaning of the cotton fibers by cleaning machines and the rate of processing of the cotton fibers by at least one carding machine.

Abstract: The separation of impurities through an opening in the casing of a rotating roller or drum is increased by guide grooves or guide gaps in the casing. The guide grooves or guide gaps extend in the direction of movement of the conveyed fibers and open out into the separating opening. The guide grooves may be formed directly in the casing in the surface facing the rotating roller or drum or may be formed by separate elements which are mounted on the casing and extend into the separating opening.

Abstract: Machine setting values containing similar functions are grouped together as a group in a setting value table and as many tables, as present groups, are correlated to machine operating elements. Parameter vectors are obtained from each table, effectuating a predetermined machine setting and the totality of the parameter vectors represent (for instance along a diagram axis) settings for the associated operating element. The group formation of setting values for a fine cleaning machine encompasses, for instance, setting values of the knife or carding element-distance from the beater circle, the point density of the carding element, the clamping distance of the feed trough or funnel from the clothing of the opening roller, and the rotational speed of the opening roller. These setting values are grouped together in a first group and included in a first table for forming parameter vectors for the cleaning intensity.

The plurality of parameters includes ambient, processing and measurement parameters. The parameters are converted and combined during processing. The resulting data relates only to individual property parameters and their changes per unit of time and are reduced to standard conditions with respect to ambient and processing parameters. The apparatus includes a plurality of sensors, a calibrating unit and a processing unit that function to continuously measure a quantity of material per length of the sliver and a variation in a fineness of the fiber per unit of time.

Abstract: The method for mixing textile fibers utilizes a computer which is inputted with data concerning the characteristics of the fibers of the individual fiber bales to be processed as well as the data indicative of the desired characteristics of the board sliver or yarn which is to be manufactured from the fiber mixture obtained from the fibers of the individual bales. From the inputted data, the computer, in accordance with a predetermined computing algorithm, calculates a component distribution which comes close to the estimated component distribution and which satisfies the desired characteristics of the car sliver or yarn characteristics. The computer may also effect a correction of the computed component distribution taking into account boundary conditions with additional inputted information.

Abstract: In order to grind clothing of a carding element, such as a cylinder of a textile machine, such as a card, during operation of the cylinder, a slide is moved back-and-forth across the clothing. The slide is reciprocated back-and-forth by an inner run of a drive belt guided in guides such that the drive belt together with a grinding element, like a grinding stone, closes a housing totally covering the arrangement. As a result, neither grinding dust nor fibers can enter the housing. Each time the grinding stone moves past a grinding member, such as a diamond rake or diamond roller this grinding stone is re-ground, so that the clothing is maintained sharpened by the continuous grinding operation and the grinding stone itself is cleaned or re-ground by the grinding member. Also, structure detects the degree of wear of the grinding element so that upon reaching a predetermined value such grinding element can be replaced.

Abstract: A method for enabling the cleaning of fibers in a fiber cleaning machine in which a cleaning stream moves tufts around a rotating cleaning cylinder, the tufts being cleaned and opened. The cleaning action can be adapted to fibers of varying origin and to an increasing degree of opening in the course of cleaning. The cleaning stream is, to a large extent, controlled and controllable by decoupling it from the dynamic behavior of the transport streams which transport material to and away from the cleaning process. Compensation for variations in the cleaning stream, and in the material supplied for cleaning, are achieved by control of the cleaning intensity, in order that the tufts emerging from the cleaning process are constant and optimally cleaned and opened. The invention concerns also suitable fiber cleaning apparatus for the realization of the described method. The apparatus includes a cleaning cylinder positioned in a casing and a plurality of cleaning elements extending from the cylinder.

Abstract: The cleaning or blow room line comprises at least one bale opening machine connected by ducts and at least one cleaning machine and a blender with a plurality of cards. The transport of the fiber flocks extracted by the at least one bale opening machine through the cleaning line is achieved by suction ventilators provided for such cleaning line. After at least one cleaning location a pressure sensor is arranged in an associated duct and delivers a signal to a control or regulator which controls or regulates, as the case may be, the size of a false air opening which co-dictates the air flow through the ducts. The false air opening can be constructed as an adjustable element in the form of a hinged flap or a slide element positioned relative to an opening in a duct, whereby the regulator controls the extent to which the flap or slide member is pivoted or slid, thereby adjusting the amount of air that is drawn into the duct.

Abstract: A fiber opening and cleaning machine includes an opening roll provided with inclined beater elements. Such beater elements have a wave shaped design and are considerably less in diameter than the relatively larger diameter beater rods customarily used in such machines. The advantage of the wave shaped beater elements lies in the grasping and spiral conveying of the fiber flocks fed into the machine.
