ABSTRACT:
A machine for squeeze testing glass containers comprising a test station, including a fixed pad having a curved container engaging surface and an opposed wheel selectively spaced from the surface, rotating at a predetermined surface speed and in the direction required to roll a container delivered to the station along the curved surface until it is released therefrom. A conveyor delivers containers to the test station and carrys released containers away from the test station. A roller is rotatable about an axis parallel to the axis of rotation of the wheel and defines with the wheel a path through which released containers will pass. The roller is biased forward to a selected location whereat the distance between the roller and the wheel is less than the outer diameter of a released container, and the roller is rotated at a surface speed selected to reduce the rotation of a released container, which passes between the wheel and the roller.
