ABSTRACT:
A closure plate to close the open end of a feed chute for a bottle crusher or the like. The closure plate includes a plurality of sheets of relatively stiff but resilient material each having a plurality of equally spaced apart slits extending radially outwardly from the center thereof toward the outer edge of the sheet to form a plurality of flexible tongue segments with the slits of one sheet being offset relative to the slits of the adjacent sheet so that the tongue segments of one sheet overlap the slits of the adjacent sheet. The closure plate may be formed by casting or molding the sheets individually or by providing core plates and a molding cavity and molding a unitary structure with a layer of the stiff, resilient material on each side of each core plate, then slitting the layers to form the tongue segments and then removing the core plates. Alternatively, when molding a unitary structure, the core plates may have outwardly projecting ribs so that the slits in the layers are formed during the molding step.
