ABSTRACT:
An apparatus for making a fabricless surface covering from particles of synthetic resin utilizes an oven assembly having a plurality of heating units which are automatically and/or manually adjustable for establishing and maintaining a preselected across the several successive heating zones progressively increasing temperature within the oven assembly. The particles of synthetic resin are deposited from a hopper onto a conveyer means which transports them through a leveler assembly and a compactor before reaching the oven assembly. After being fused by the application thereto of heat as it passes through an oven assembly, the synthetic resin is fed through an embossing unit, around a cooling drum and to a trimmer. Then after being trimmed, the fused synthetic resin passes through a coater assembly which applies a coating to a fused resin before the latter leaves the apparatus.
