Abstract (en)
[origin: GB2036102A] The inventive method is used for producing of measuring values depending on the linear density of a fibre sliver transported through a measuring funnel. A measuring signal transmitted from the measuring funnel (2) is transformed into a proportional electric voltage signal and is continually integrated. The inventive apparatus comprises the so-called measuring funnel connected pneumatically with a pneumatic/electric transducer (4). The transducer transmits its signal to an integration circuit arrangement (6). A control logic device (13) on one hand cooperates with a gear (11) of a gear arrangement (10) of a spinning preparatory machine and on the other hand is connected with the integrating circuit arrangement. A proximity initiator (12) transmits an impulse to the control logic arrangement at each passage of a tooth. The integrating circuit supplies measuring values suitable as a control signal for spinning preparatory machines, which signal is independent of the speed of the fibre sliver.
