Abstract

See full text

An apparatus for reflow smoothing a molded article made by first heating a face of a mold at a first station, then applying a fusible synthetic resin to the heated face and thereby melting the resin into a continuous coating covering the heated mold face at a second station spaced angularly from the first station, and cooling the coating and mold at the second station until the coating hardens. To reflow smooth the article, the surface of the cooled coating is then smoothed by confining the mold and hardened coating in a substantially closed chamber at the second station and reheating the confined coating until its surface flows. Thereafter the coating is cooled again at a third station angularly spaced from and downstream of the second station until it hardens and the hardened covering is stripped from the mold at a fourth station angularly spaced downstream of the third station and upstream of the first station.
