Apparatus for testing glass containers for structural defects which may occur in the sidewalls thereof and which may render the containers incapable of withstanding a normal handling through a filling line and packing where the containers will be subjected to abuse. The apparatus is particularly designed to handle non-round bottles or containers and essentially takes the form of a pair of vertically oriented, rotatable, bottle-engaging rollers which, upon engagement with opposite sides of the bottle, will move the bottle through the gap between the two rollers. One of the rollers is laterally movable and biased toward the other roller, which has its axis fixed. An adjustable pneumatic pillow having a controllable pressure is positioned to be used to bias the mounting for the movable roller. The movable roller and its mounting structure has limited movement about a vertical pivot that is non-coincident with the vertical axis of the roller. When a defective container is engaged by the two rollers, the container will be broken. By slight modifications of the drive system for rotating the two opposed rollers, the apparatus is adaptable for testing round containers and convex-concave flasks. The positioning of the rollers relative to a conveyor that brings the bottles to the area between the rollers is such that the bottles, when gripped between the two rotating rollers, are close to or adjacent the edge of the conveyor such that broken glass may fall from the conveyor into a cullet chute and not be carried on the top of the conveyor.
