ABSTRACT:
A transfer and molding apparatus for transferring an image or pattern from an elongate transfer film to a molded article. The transferring and molding apparatus includes a film feed-out mechanism for feeding the transfer film wound around a supply drum and introducing the transfer film between a stationary mold member and a movable mold member and a film take-up mechanism for taking up the transfer film positioned between the stationary mold member and the movable mold member onto a take-up drum. A longitudinal direction feeding device has a controlling motor for feeding the transfer film in a longitudinal direction thereof from the film feed-out mechanism toward the film take-up mechanism by a predetermined length during each molding cycle, and a longitudinal direction sensor for detects a position setting mark on the transfer film. When the mold is open to separate the stationary and movable mold members, the controlling motor is rotated at a high speed until immediately before an amount of the transfer film being fed reaches a predetermined value and thereafter it is switched to a low speed. Then when the longitudinal direction sensor detects the position setting mark, the controlling motor is once stopped, and thereafter the controlling motor is further rotated by a preset rotational angle.
