Abstract: In an apparatus on a spinning preparation machine, at least one machine element lies opposite and spaced apart from the clothing of a roller, and bearing surfaces of the end portions of the machine element are in engagement with respective bearing surfaces of stationary bearings. An adjustment means is arranged in the region of each of the end portions for altering the radial spacing between the clothing of the roller and the machine element. To enable the carding nip to be adapted or kept constant in the event of thermally induced changes in dimensions, the machine element and the bearings each have inclined bearing surfaces, and the machine element, in the event of undergoing thermally induced expansion in its longitudinal direction, is so displaceable along the sloping surfaces that the radial spacing remains the same.

Abstract: A card top bar for a carding machine, has a carrying member and a releasable clothing portion in which card top bar there are provided two card top heads, each of which slides on a slideway, the card top heads comprise at least one sliding region, which is in contact with the slideway, and at least one fixing region, which is in engagement with the rest of the card top bar and which at the same time holds the sliding region. In order to improve the card top bar, the card top heads are in engagement with the carrier for the clothing.

Abstract: In an apparatus on a carding machine for textile fibres, for example, cotton, synthetic fibres and the like, comprising revolving card flat bars equipped with clothing, in which a space is present between the tips of the card flat clothings and the tips of the cylinder clothing and the card flat clothings form an adjustable angle with the cylinder clothing, the ends of the card-flat bars each slide with one part on a first curved slideway and with another part on a second curved slideway and the sliding-contact surfaces of the slideways—viewed circumferentially—are different distances from one another. To produce an apparatus that is structurally simple and easy to assemble, enables the carding intensity of the card flat bars to be individually adjusted and allows wear of the clothing of the card flat bars to be reduced, the sliding-contact surfaces are arranged so that the distances between the sliding-contact surfaces both increase and decrease.

The machine may have further elements influencing the carding nip. In order to make possible a carding nip between the cylinder and the clothed and/or unclothed counterpart element that remains constant or virtually constant when heat is generated, the parts influencing the carding nip are so construed that they have thermal expansion characteristics which are such that, when subjected to the heat acting on them in use, the carding nip remains substantially constant.

In order to improve measurement of the mass of fibre material in a cleaning system, especially between a bale opener and carding machine, and to use that measurement for closed-loop and/or open-loop control, the fibre material is present in the form of fibre flocks and the fibre flocks pass through a measurement pathway having a measuring device having the at least one microwave resonator.

Abstract: In the case of an apparatus for a sliver-forming textile machine, especially a draw frame, flat card or the like, a fibre structure (fibre web) coming from the delivery rollers of a drafting system passes through a web guide and a sliver funnel with take-off rollers, the web guide has an inner wall (deflection and/or guide face), and a frictional resistance offered by the inner wall acts on the fibre structure. In order to allow in a simple manner an improved web guidance and sliver quality, and to permit the web guide to be adapted to different technical parameters, such as fibre material properties, working speed, a parameter relating to contact between fibre structure and inner wall is alterable.
