ABSTRACT:
Apparatus and method for applying plastic base cups to plastic containers, such plastic containers being blow-molded, having round bottoms and being unable to stand erect, such base cups providing a flat, stable base for the container. Cups are supplied automatically to holders or sockets at a cup receiving station; they are then indexed to an adhesive applying station where a circular line of adhesive is applied to the bottom of the cup by spinning the cup; the cup is then indexed to a container delivery station, where a container is deposited in the cup, and air under pressure is applied to the interior of the container to apply pressure to the glue line, such pressure also acting to smooth out irregularities in the container. Each container-cup assembly is removed at a removal station. Detector means may be employed at or ahead of the adhesive applying station to determine whether a cup is present in a holder. Following the container delivery station, pressure testing, leak testing and/or alignment testing stations may be provided.
