Seam Inspection

Precision, reliability and versatility

This system has been installed in many countries worldwide, to check the double-overlap closure seam on various can sizes and shapes.



The Lizotte Can 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.

At an optional station, an image from the top is acquired and inspects for defects including dents, absent or miss-placed pull-tab, and over-filling.

Lizotte specializes in custom-built equipment. Hence, we would be pleased to supply a personalized system that would fulfill your operational requirements.
