  • Patent number: 4137487
    Abstract: A method and apparatus for automatically leveling a band of fibers such as sliver, roving and the like by varying the drafting speed of a drafting mechanism responsive to variations in the thickness of the band. Analogue signals are produced by variations in the thickness of the band and are converted to digital signals for being stored in a digital register. After a period of time, corresponding with the time for conveyance of the scanned point in the sliver up to and into the draft zone, the information is read out of the storage register and converted back to an analogue signal. The analogue signal is compared with another signal representing the actual drafting speed for producing a compared signal for controlling the drafting speed.

  • Patent number: 4126915
    Abstract: An apparatus is illustrated which is especially useful for cleaning the flats of a textile carding machine wherein a rotatable suction conduit has circumferentially spaced slots therein which are successively exposed in cleaning relation to successive flat or carding surfaces by means of a substantially imperforate flexible cover sheet extending about the rotatable suction conduit, being fixed on one end so that the cover extends as a shroud preferably extending in the direction of rotation of the conduit away from the fixed end so as to leave an opening between opposed ends of the shroud. The shroud covers the slots rendering them inactive so that only that slot portion between opposed ends of the shroud actively exert suction. Thus, the suction is concentrated at a specific area, between the ends of the cover, adjacent a limited portion of a flat while permitting rotation of the suction conduit without buildup of excessive lint accumulation as to interfere with the operation of the conduit.
