ABSTRACT:
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.
