摘要： An apparatus for feeding a fiber batt to a fiber processing machine includes a feed roll; a feed table formed of a plurality of separately movable feed table segments each cooperating with the feed roll and defining therewith a nip through which the fiber batt passes; a plurality of springs each being affixed to the feed table segment to form integral components therewith; and an elongated holding element extending spaced from, and generally parallel to the feed roll. Each spring is affixed to the holding element. The feed table segments are individually movable away from the feed roll against a force of respective springs in response to thickness variations in the fiber batt as the fiber batt passes through the nip. There is further provided a support for rotatably supporting the holding element. The feed table segments impart torques on the holding element through the respective springs as a function of movements of the feed table segments and the holding element is rotated by the torques to an extent representing a sum of the torques. A sensor is connected to the holding element for generating a signal as a function of rotary displacements of the holding element.

摘要： The invention relates to the correction of an error-prone measuring signal of a pair of scanning rollers. The measuring signal is influenced by the circularity error of the pair of scanning rollers and/or by the eccentric mounting of the pair of scanning rollers. The pair of scanning rollers is used to measure the thickness of a fiber fleece or fiber sliver on a pre-spinning machine in the textile industry. The occurrence of a periodic error value in the measuring signal due to circularity error and/or eccentricity of the pair of scanning rollers is detected. The error value is stored in a position-related manner for one revolution of the scanning rollers and the stored error value is used in the operation of the scanning rollers within the cycles of rotation for the correction of the current, position-synchronous measuring signals.

摘要： 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.

摘要： Non-woven fabrics are manufactured using a carding machine with outlet comb, a blamire feed or spreader/batt-making machine with cylinders for depositing a web of fibers, and one or more needling devices. The surface weight of the web delivered by the carding machine to the blamire feed is modified by varying the speed of the comb as a function of the changing positions of the cylinders whereby a batt of variable surface weight over its width is obtained so as to counteract the distortions of surface weight distribution produced by the needling devices.

摘要： A first pair of complementary transistors with their collectors connected to one terminal of the motor winding are alternately switched on by a rectangular wave produced by a Hall-IC responding to the magnetic field of a permanent magnet rotor, the square wave being coupled to these transistors through a resistor network and series capacitors. At the same time, another pair of complementary transistors, having their emitters connected to the other terminal of the motor winding, is directly switched by the Hall-IC, so that they operate as voltage followers to complete the path of the current pulses of the winding through the other half of a full-bridge circuit. Thus, one signal from a single sensor of rotor position operates a stator winding with full protection of the components while using a minimum of circuit elements. Such a motor makes possible ventilating fans of small axial length for use in compact apparatus.
