Abstract

A wear plate for use in a rotary capping machine used to apply caps onto the upper threaded neck of a series of plastic containers, having a generally cylindrical body with an outer cylindrical periphery with a diameter and a pedaloid base with spaced pads separated by radial recesses extending from a center recess, as the containers are moved along a circular path by a star wheel with outwardly protruding pockets supporting the necks of the containers. The wear plate being a flat ring rotated in unison with the star wheel about a machine axis and adapted to support the containers, the ring having an upwardly facing flat surface and a series of container receiving nests movable in the circular path as the ring is rotated, each of the nests having an inner flat area and at least one elongated bar-like abutment projecting upwardly from the flat surface a given vertical distance and extending in a direction radial of the inner area.
