The Panel Side Trim machine provides the user with the option of trimming the longitudinal sides of the panel producing a uniform consistent panel. As the panel assembly is indexed through the production line, the longitudinal sides of the panel are trimmed via cutting wheels. The panel is guided on edge of the panel before and after the trim operation. Scrap is collected in collection bins (scrap is manually removed from the machine). The interval of scrap removal from the production line will depend on the production rate.
