Full Description

This innovative solution automatically eject cans with seaming defects and/or internal foreign materials.


Seam inspection: The Lizotte Can Grader have been installed in many countries worldwide, to check the double-overlap closure seam on various can sizes and shapes. The grader acquires a perimeter view of the seam by using six synchronized cameras and a creatively designed lighting chamber. In the images, our specialized software finds the top and underside of the seam, and evaluates the seam for overall straightness, for width, and for variations in height, any of which could indicate a defect.

Inspection for Foreign Materials: Lizotte uses non-destructive x-ray to inspect tin cans of various sizes and shapes for internal foreign materials.
