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.

Method of and installation for optimizing the process of cleaning cotton

An apparatus for precisely orienting working elements, such as carding elements, to a rotating fiber-opening roller, such as a licker-in, with regard to both distancing and centering without necessitating complex adjustment mechanisms. The working element is precisely positioned by virtue of respective abutting engagement surfaces of the axle boxes or roller retainers and the carrier of the working elements.

Apparatus for attaching working elements

Improved connection between a revolving flat card and a drive belt. A connection between a flat rod of a revolving flat card and a flexible drive belt for the flat rods, having a flexible connecting element formed integrally with the drive belt and the connecting element being received directly in a part of the flat rod, for forming a snap-on connection, with the drive belt being arranged on a side opposite of the flat rod and including a flexible projection, with the projection being adapted for a frictional engagement, in a clampable manner, with a respective receiving element located at the ends of the flat rod.

Connection between a revolving flat car and a drive belt

An apparatus for attaching working elements, such as carding elements, to a rotating fiber-opening roller, such as a licker-in, wherein the working element is attached on the axle boxes or retainers of the roller by means of an end cap at least partially encompassing the axle boxes or axle retainers.

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 offset distance between a fiber guide and knife and the length of the separation gap between the knife and fiber guide are grouped together in a second group and included in a second table for the formation of parameter vectors for the quantity of waste. The setting elements of the fine cleaning machine can be linked by these parameter vectors and characteristic numbers of the parameter vectors are correlated to a respective operating element, which operating elements, due to linking of the setting elements by the table-linking, in each setting collectively define a working point of the fine cleaning machine.

Apparatus for controlling machines for cleaning of fibers

A carding machine is provided with a built-in clothing grinding system which can move a grinding element from a waiting position over the processing width of a carding machine, with a control unit being provided for controlling the work of the grinding element.

Controlled grinding of clothing

A bale opening machine is provided with a safety apparatus, by means of which there are produced safety barriers or fences parallel to lengthwise sides of a row of bales to be opened and/or substantially perpendicular to the direction of movement of the bale opening machine. The safety apparatus moves in conjunction with the bale opening machine. The safety apparatus can comprise mechanical and/or sensory protective structure. The sensory protective structure comprises one or more electro-acoustical transducers arranged in a sonic chute together with one or more reference reflectors such that transmitted acoustical signals are split into a measuring signal and a reference signal. The reference signal is reflected at one of the reference reflectors, whereas the measuring signal is reflected at a deflection reflector into the monitored area and back again by an object located in the monitored area.

The working width of a carding machine for short staple fiber carding is reduced. As a result, the precision of the working elements and the complete arrangement is increased. The productivity of the carding machine is thus also increased.

Ultra-high performance carding machine

A method and apparatus for converting measurement data pertaining to slivers and fibers originating from a continuous measurement that is dependent upon a plurality of parameters to calibration values. 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.

Method and apparatus for continuously determining the fineness of fibers

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. The component distribution found by the computer is used for the adjustment or regulation of the supply of individual fiber components to a mixer in order to obtain the calculated component distribution in the fiber mixture which si delivered by the mixer.

Method of blending textile fibers

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.

Apparatus for grinding clothing, such as the clothing of a carding

The present invention is directed to a drawframe having a sliver delivery device and a computer part for maintaining a predetermined quality of sliver, wherein there is a predetermined overproduction from a card and/or a drawframe relative to a spinning machine. The arrangement temporarily decreases production to temporarily compensate for the overproductions. The sliver which is produced during the decrease in production may be delivered to a separate can.
