    • 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.
    • 在纺丝制备机上的装置中,至少一个机器元件位于与辊子的衣服相对且间隔开的位置,并且机器元件的端部的轴承表面与固定轴承的相应支承表面接合。 在每个端部的区域中布置有调节装置,用于改变辊的衣服和机器元件之间的径向间隔。 为了在热引起的尺寸变化的情况下使梳理辊隙适应或保持恒定,机器元件和轴承各自具有倾斜的支承表面,并且机器元件在其沿纵向方向发生热致膨胀的情况下 沿着倾斜表面可移动,径向间隔保持相同。

    • Automatic modification of volumetric air flow in an apparatus for pneumatically feeding a spinning preparation machine, by means of fiber-flock charging shafts located upstream of individual spinning preparation machines and connected to a pneumatic fiber-transporting line, the transporting line connected by way of a fiber material feed fan to the fiber-processing machine upstream.A set of characteristic curves describing air flow is stored in a characteristic curve set element; a measurement signal for the pressure difference at the fan and values relating to rotation of the fan are ascertained in a computer unit. The computer unit determines value of the volumetric air flow from the characteristic curves. In the event of departure from a desired value for the volumetric air flow, the operating point for the speed of rotation of the fan is displaced to the desired value.
