A wool card includes a rotatable Morel roller and first and second burr beaters rotatable relative to the Morel roller and relative to each other and spaced apart about the periphery of the Morel roller. The wool to be carded moves in one direction about the Morel roller and between the first burr beater and the Morel roller and then between the second burr beater and the Morel roller. The first burr beater turns at a lower speed than the second burr beater. The burr beaters have blades thereon which contact the wool to remove impurities from the wool. The number of blades on the first burr beater is less than the number of blades on the second burr beater.

The present invention concerns a wool card applicable in the field of the textile industry. The card is characterized in that it is equipped with at least three Morel rollers (1), in that it does not have an intermediate comb and in that the tangential velocities of the feeder rollers (2) and the large drum (3) are equal, the reduction in speed of the fiber web between the large drum (3) and the following Morel roller (1) being relatively low.

The combination of a rotatable spindle and a bobbin receivable on the spindle for winding fibers on the bobbin. The spindle has an upper free end, and on this upper free end there is an elastically deformable drive for the bobbin, comprising a circular array of spaced resilient spring leaves. The bobbin is hollow and has on its interior a correspondingly spaced series of recesses that receive the spring leaves so that rotation of the spindle is transmitted to the bobbin via the spring leaves and recesses. The spring leaves are secured to the spindle at their lower ends and extend upwardly and radially outwardly from their lower ends and terminate in free ends that extend upwardly and radially inwardly relative to the axis of rotation of the spindle.

Process and apparatus for the automatic removal of bobbins from a bank of spindles. A transporting fork has a plurality of recesses for simultaneously handling a plurality of spindles. The transporting fork is movable in a vertical direction and in at least one horizontal direction parallel to a bank of spindles on a spindle carrying carriage. A cup is insertable over each spindle for the support and manipulation of bobbins. A conveyor evacuates full bobbins and supplies empty bobbins. The fork releasably retains a cup in each recess whereby each cup can be penetrated by and disengaged from the fork upon movement of the fork in a horizontal direction.

A textile machine has a bank of spindles each provided with a flyer having a presser finger and a fork having a plurality of elongated teeth thereon for simultaneously removing full bobbins from the spindles and for supplying empty bobbins to the spindles. A safety device is provided for moving the presser fingers out of the paths of the empty bobbins as the empty bobbins are inserted into the flyers, comprising deformable elements extending longitudinally of the teeth of the fork. The presser fingers have members thereon so positioned as to be engaged by the deformable elements and to swing the presser fingers out of the paths of the empty bobbins when the empty bobbins are inserted into the flyers by movement of the fork in one direction. The presser finger members are also so positioned as to engage the deformable elements upon movement of the fork in a direction opposite that one direction after emplacement of the empty bobbins on the spindles in the flyers, to urge the presser fingers to swing toward the empty bobbins. The deformable elements are in the form of an elongated brush.
