In one embodiment of the rolls a predetermined number of threaded apertures is formed in the surface of the roll and each tooth member has a threaded mounting stud formed thereon, which threadably engages the aperture. The threaded apertures can be formed by the insertion of a cylindrical plug in a predetermined number of the product pickup apertures, each of the cylindrical plugs having a threaded aperture formed longitudinally therein…
