Abstract: A rubber wear layer is molded to a metal sheet, which is relatively thin, in comparison with a side rail for tensioning a vibrating screen, then attached to the side rail, as above a flange which provides a connection with the screen. The rubber layer and sheet may be wider than the width desired for the rail, in which event the wear layer and sheet are trimmed to the desired width, as by shearing. The rubber layer may also have a width less than the sheet, so as to leave a lip along one edge. The aforesaid attachment is made by pins propelled by an explosive charge through the bonded layer, the sheet and the plate at spaced positions. A head of each pin abuts the sheet and the portion which extends past the plate is removed, as by grinding. The sheet may be additionally attached to the rail by spot welds at spaced psitions on the lip, which prevents the heat of welding from adversely affecting the rubber. The lip is placed on the plate opposite the flange which connects with the screen.
