Full Description

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 inspect for defects including dents, absent or miss-placed pull-tab and over-filling.
