ABSTRACT:
The invention relates to a machine for removing basecups from plastic bottles in which basecups are bonded or adhered to the bottom thereof. The machine includes conveyor means adapted to pass bottles towards a cutting station. The machine further includes laterally spaced apart stripping rails positioned below and spaced apart from the conveyor means, the arrangement being such that necks of bottles are gripped by and between the conveyor means, while the stripping rails engage over or above the basecups, passage of the bottles towards the cutting station by the conveyor means, causing the stripping rails to force the basecups downwardly and away from the bottles, thereby breaking any bond or adhesion therebetween and separating the basecups from the bottles. The cutting station includes means which thereafter remove a lower portion of the bottle as contaminated with bonding agent or adhesive, as a result of the bond between the bottles and the basecups.
