  • Patent number: 4819301
    Abstract: The present invention relates to a method and an apparatus for controlling the drafing of sliver in a draw frame in which sliver first travels through an advance sensing means that senses variations in the mass, then passes through a drafting means which is located after the advance sensing means and is provided with an adjustable draft, and finally travels through an after sensing means located after the drafting means which senses the mass per unit of length, whereby the draft of the drafting means is varied to compensate for variations in mass of sliver in response to the sensed variations in mass evaluated in a time-delayed manner and of the difference of the measured mass per unit length of the output and of a selectable theoretical value for the mass per unit of length.

  • Patent number: 4815170
    Abstract: A carding machine includes a licker-in and a waste separator cooperating therewith. The waste separator includes first and second plates arranged consecutively along a periphery of the licker-in. The first and second plates are spaced from one another by a clearance constituting a waste outlet opening through which waste is discharged with the aid of a circumferential air stream generated by the rotation of the licker-in. The first and second plates each have a pivotally supported end for adjusting their angular position, whereby a radial distance from the periphery of the licker-in is varied for controlling the discharge of waste through the outlet opening. A nozzle is arranged at the licker-in at a location generally diametrically opposite the waste outlet opening. The nozzle has an outlet aperture merging into a space situated immediately radially outwardly of the periphery of the licker-in.

  • Patent number: 4809404
    Abstract: Apparatus for compacting a nonwoven textile fabric mat is disclosed which includes an arrangement of rollers having a pair of juxtaposed rollers (2,3) and a superposed roller (4) arranged in a fiber compacting arrangement. Juxtaposed rollers (2,3) are spaced apart to define a space (9) in which central superposed roller (4) extends for compacting fibers. Perforations (5) extend through the surface of a shell (6) of each of the rollers. A first conveyor (16,19) conveys the textile fibers to the roller arrangement and a second conveyor belt (17,20) conveys the fibers away from the roller arrangement. Belts (19,20) may be perforated and surround rollers (2,3), respectively. Suction applied to the interior of the rollers assists in compacting the fibers in the mat as air is drawn through perforations (5) which are of a predetermined diameter and shape.
