Lagging-reinforced structure

A lagging-reinforced conveyor comprising:

• (a) a flexible substrate having a predetermined width,
• (b) a lining layer coated on a first surface of said substrate, said lining layer being made of a flexible resilient material, and
• (c) a plurality of laggings embedded in said lining layer, said laggings each having a first flange portion of a width substantially equal to the width of said substrate, a second flange portion of a length substantially equal to the width of said substrate and facing said substrate, said second flange portion being parallel to and spaced from said first flange portion, and a vertical rib portion which has first and second opposite edges integrally connected to central portions of said first and second flange portions, respectively, said laggings being made of a material of high hardness and high wear resistance, each of said laggings defining first and second rectangular grooves on opposite respective sides of said vertical rib portion into which portions of said lining layer extend, said portions of said lining layer having the same shape and size as said rectangular grooves and being firmly engaged therein, the sum of the depths of said grooves being large as compared with the transverse dimensions of said first and second flanges, whereby the removal of said laggings from said lining layer is prevented by the engagement of said portion of said lining layer with said grooves.
