PROCESS AND APPARATUS FOR MOLDING A SHINGLE, FOR COOLING A SHINGLE, FOR APPLYING A CURVATURE THERETO AND CARRIER PLATE FOR FACILITATING THE PROCESS |
摘要 |
Shingle material, preferably comprising a core with a capstock applied thereto is extruded preferably by means of a co-extrusion process onto a series of Individual carrier plates, with the shingle material then being severed such that each carrier plate carries its own layer of shingle material thereon and the carrier plates are then delivered to a compression mold in which the shingle is molded. The carrier plate and shingle Is then removed from the mold and carried through a series of hold-down stations, after which the shingle is delivered to a trimmer, where flashing is simultaneously trimmed from its edges. The shingle Is then cooled, preferably by sandwiching it between upper and lower retention members which are cooled via a cooling tower. The reten-tion members impart a curvature to the shingle. The carrier plates are returned via a return conveyor to be heated, for re-use |
