Abstract (en)
[origin: EP0332168A1] Known devices comprise a transport channel (4), a nozzle channel (5) adjoining the latter in the transport direction (T), and a flow generator for producing a flow of transport gas in the transport channel. A lateral orifice (13), which permits the gas flow to flow off, is provided in the opening region of the nozzle channel (5). <??>To be able to carry out pressure measurements in a measuring funnel using a known device, the device has a control (40) by means of which the lateral orifices (13) can be closed. Once the orifice is closed, a pressure builds up in the narrowing nozzle channel which can be measured with a pressure sensor (42). The measured pressure corresponds to the thickness of the sliver and can be used to control a preceding card. <??>The device is applied for the conveyance of card slivers. <IMAGE>
