ABSTRACT:
A rotary stripper, which can be chucked to a drive shaft, comprises a pair of discs spaced by a centrally positioned intermediate hub which has radial slots. Immediately outward of the hub and arranged in a ring concentric thereto are a series of equidistantly spaced pins, the axes of which are parallel to the central axis of the hub. The location of the pins, in a circular sense, places one thereof at and in adjacent relation to the outer end of each slot, offset from a direct alignment with the slot. The offset in each case is in a direction counter to that in which the hub is intended to rotate in use.
Stripper elements which are relatively rigid but have a minor degree of flexibility are simultaneously slip fit to each pin and in the slot adjacent thereto and are resiliently mounted thereby to the hub. The stripper elements are contained by the discs to either end of the hub. One of these discs is integral with the hub and the other releasably attached to the pins, the axial length of which is slightly greater than that of the hub.
In preferred embodiments the stripper elements are free to float in a sense axially of the hub.
