In a seal removal station positioned along a bottle conveyor line upstream of a filling operation, oversized adhesive seals covering the mouths of plastic bottles are lifted off each bottle and transferred to a collector bin. Vacuum pressure generated in a plenum chamber formed in a stator member is transmitted to the non-adhesive upper surface of each seal through a perforated rotor surface rotating beneath the stator. Air jet means directing fluid pressure upward against overlapping marginal portions of each seal and guide surfaces to flatten out curled portions of the seal are utilized to assure seal lift off by virtue of fluid pressure differentials. A removed seal is kept adhered to the moving rotor surface by the maintenance of vacuum pressure above the seal. Adjacent to the collector bin, a further plenum having pressure air therein communicates through the rotor perforations with the adhered seal to propel the seal into the bin.

A method of removing oversized adhesive seals from container openings in a seal removal station as the containers are passed in seriatim into said seal removal station, said method comprising: rotating a rotor member over said flow of containers in said station, said rotor member having a circular surface formed with fluid passages extending therethrough, mounting a stator member in a fixed position relative to said rotor in adjacent abutting relation to said rotor circular surface at a side opposed from said flow of containers and communicating with the other side through said fluid passages, said stator having formed therein first and second spaced apart plenum chambers, communicating said first plenum with sub-atmospheric pressure and said second plenum with above atmospheric pressure, passing said seals beneath said first plenum, and directing pressure air beneath each said seal on its respective container opening as said each seal passes beneath said first plenum.
