ABSTRACT:
A continuous flexible metal band surrounding a molding wheel and rotating therewith engages the wheel through an arc less than 180.degree., e.g. 110.degree., and is maintained with a substantial inward radius of curvature throughout its entire length. This permits the employment of bands with cavities therein and having thicknesses several times greater than 0.001 times the diameter of the molding wheel without fatigue and failure of the band.
