Abstract
An apparatus for forming an annular liner is equipped with a molding assembly which includes a press tool assembly and an anvil. The container closure shell is fed onto the anvil. The press tool assembly has a resin flow path and a means for forcibly flowing a synthetic resin material through the resin flow path. A notch is formed in the upstream portion of the resin flow path. When the molding assembly moves with respect to the feeding nozzle, the synthetic resin material discharged from the discharge port of a feeding nozzle enters into the upstream portion of the resin flow path via the notch, and is cut away from the feeding nozzle.
