ABSTRACT:
An apparatus for trimming the neck of a blow molded plastic bottle in which a reverse punch is mounted on an end of a shaft. A knife is also mounted to the shaft adjacent to the reverse punch and includes a cutting edge recessed from the cutting edge of the reverse punch. A stripper arm is mounted on the shaft and axially moves with the shaft. The stripper arm's distal end is adjacent to the reverse punch and recessed from the cutting edge of the reverse punch. An actuator causes the distal end of the stripper arm to move to a position located radially outward from the cutting surface when a trimmer ring from the neck of a bottle is to be removed from the apparatus.
