Abstract: In the process and apparatus for loading a ring spinning machine with roving-supply bobbins at least two bobbins rows extending longitudinally on each side of the spinning machine supply roving to the work stations and a auxiliary bobbin row which can travel in with full bobbons and out with empty bobbins are provided. According to our invention an exchange process is provided comprising replacing the roving of the bobbins in one of the bobbins rows supplying the roving which is being consumed by the roving of the auxiliary bobbin row which has been brought in with full bobbins. Thus the auxiliary bobbin row becomes one of the bobbin rows dispensing the roving while the bobbin row being replaced now becomes the auxiliary bobbin row with empty bobbins and is taken away. A new auxiliary bobbin row with full bobbins is then brought in. The exchange process is repeated for each of the bobbin rows as the roving is exhausted. A simple space saving apparatus for performing this process is described.

Abstract: A draw frame of a sliver-drafting apparatus has three cascaded roller pairs whose lower rollers are driven by respective motors at speeds determined by associated frequency dividers and/or multipliers in the output of a common oscillator of adjustable operating frequency. The slivers drafted by the roller pairs form, after doubling or plying, a fiber bundle traversing a thickness sensor whose output, integrated over predetermined time periods, is used by a microcomputer to ascertain optimum nip-line spacings and contact pressures reducing the thickness variations to a minimum. These parameters can be varied by horizontal slides supporting the roller pairs and spring-loaded blocks acting upon the shafts of the upper rollers; the positions of the slides and the pressures of the loading springs are adjustable by servomotors, under the control of the microcomputer, on the basis of a running-in program in which different combinations of values for the spacings and the pressures are successively set up and the combinations yielding the highest degree of uniformity are subsequently re-established.

Abstract: The method of automatically measuring tube wall thickness includes axially introducing an radio-active radiation source into the tube to be measured and directing its radiation at about 45 degrees toward the tube wall. Other steps include distributing a plurality of scintillation counters uniformly around the tube, and measuring the transmitted radiation by said counters. The measurement values compensated for a specific wall thickness being amplified proportionally to the radiation intensity and are each adapted to be fed in a predetermined measuring time through a measuring capacitor, the charge values of the capacitors being indicated in succession and fed to a statistical measurement value detecting arrangement. Included is the preliminary step of automatically calibrating the measuring arrangement by axially introducing said radiation source into a corresponding tube with standard dimension, and measuring the radiation therethrough; and apparatus therefore.
