| 摘要 |
The invention comprises resilient lining panels formed preferably from polyurethane of certain specified hardness and provided with leading and trailing sides between which a material-engaging surface is formed which has a smoothly curved wave configuration cresting nearer the trailing than the leading side, the leading side terminating in a relatively thin wedge-shaped flange which is overlaid with a thicker clamping flange on the trailing side, and a metallic clamping member is positioned within the panels, extending between opposite ends thereof, and having flat ribs extending laterally and oppositely from a channel arrangement into at least the overlapping flanges of the trailing side of the panel to effect firm clamping against the flange on the leading side of each panel.
