A method and apparatus for assembling hollow balls from molded hemispheres which are fed to the apparatus. The hemispheres fed to the apparatus are received in a plurality of slots located about the circumference of a wheel. While the hemispheres are in the slots, an applicator disc applies a solvent to the hemispheres and pressure cams force the hemispheres together, thereby forming complete balls. The balls are then discharged from the apparatus. The same apparatus may be used to assemble hollow balls from hemispheres which are adapted to be snapped together. In that case, no solvent is applied by the applicator disc and the pressure applied by the pressure cams is used to snap the hemispheres together into hollow balls. |
