Rotary fiber forming spinner
First Claim
1. A spinner for the centrifugal production of fibers comprising an apertured circumferential wall and a bottom wall, the bottom wall being adapted with a plurality of inwardly-extending projections defining a series of convolutions extending outwardly from the center of the spinner, said convolutions having convolute paths therebetween, said convolutions having a convex edge which forms a leading edge of said projection upon rotation of said spinner.

2. A spinner for the centrifugal production of fibers comprising an apertured circumferential wall, a bottom wall and a centrally positioned support means, being adapted with a plurality of circular rows of discontinuous projections, said rows being positioned circumferential to said support means, the projections of any one row being alternately spaced in relation to the projections of the next adjacent row.
- 3. A spinner for the centrifugal production of fiber comprising an apertured circumferential wall, a bottom wall and a centrally positioned support means, the bottom wall being adapted with a plurality of projections in the form of truncated pyramids, having outwardly curved bases and forming a plurality of paths therebetween.
