Abstract:
Apparatus for attachment to a yarn spinning or spooling frame adjacent to a path of a longitudinally moving yarn being processed therein for measuring and evaluating a plurality of properties of such yarn, said apparatus comprising:a support unit for attachment to said frame; a first generally planar carrier fixed to said support unit and having fastened thereto: a first sensor selected from the group consisting of capacitive and optical sensors for measuring a property of said moving yarn, first processor means exclusively providing digital output signals derived from the values of the property of the longitudinally moving yarn sensed by said first sensor, a computer in the form of a digital signal processor for evaluating said digital output signals from said first processor means and producing digital evaluation signals, and an output connector through which the evaluation signals pass for delivery to a control unit of the spinning or spooling frame; a second generally planar carrier fixed to said support unit and having fastened thereto: a second sensor selected from the group consisting of optical and capacitive sensors for detecting a second property of said longitudinally moving yarn, and second processor means exclusively for providing digital output signals derived from the values of said second property of the longitudinally moving yarn sensed by said second sensor; and means for connecting said digital output signals from said second processor on said second carrier means to said computer on said first carrier for evaluation by said computer and delivery to a control unit of the spinning or spooling frame through said output connector on said first carrier.
