Abstract

1478903 Pneumatic fibre conveying MASCHINENFABRIK RIETER AG 2 Aug 1974 [22 Aug 1973] 34166/74 Heading D1N [Also in Division B8] The supply rate of fiber to a preparatory spinning machine is maintained constant by feeding the fiber into a duct 1 carrying a fan generated airstream, measuring a parameter characteristic of the operating conditions of the fan 2 and dependent on the quality of fiber supplied, comparing this with a set valve parameter and on deviation of one from the other adjusting the fiber feed to maintain the desired constant value. As shown in Fig. 1 a static pressure sensor 12 produces a signal in transducer 13, which feeds a zero comparator 19 and a set point comparator 21 whose signal operates a control device 23, which operates on the fibre feed roll motor 10. Additionally a pressure display instrument 15" and chart plotting instrument 15' are operated. In the Fig. 4 embodiment pressure sensors are placed at 68, 69 to determine the pressure changes through a fan 53, the fiber being introduced prior to the fan in a suction zone. Other embodiments measure the pressure change past an orifice or the torque or power requirements of the fan which are dependent on the pressure prevailing in the device.
