Abstract: The invention is a machine for producing decorative aggregate G-layer on top surfaces of claddings in cooperation with a cladding manufacturing machine. The G-layer production machine may be integrated into the cladding manufacturing machine or a standalone machine. In both options, the machines synchronize the overlaying of the top G-layer with the manufacturing process of the claddings to ensure continuous production of multi-layer claddings with a decorative aggregate layer. The overlaying itself is done under controlled condition to produce homogenous distribution of the aggregates on the top surface of the claddings to provide them an aesthetic look.

Abstract: A flexible interlocking element (10) having opposing, interlocking ends (12, 14). Element end (12), features a contour, including element top surface segment (16), extending to bend (18), then defining a tongue element (34) extending downwardly along an incline (19), to inverted bend (20), which defines a tongue side (60) having a tangent (62). The contour of the tongue, further extending downward and around to bend (22), which defines a tongue tip (58). The tongue tip (58) having a bottom (54) with a tangent (56). The tongue further extending upward along incline (26), then further extending horizontally to bend (28), then further extending vertically downward to bend (30). Bend (30) defines the lower edge of bottom surface segment (32). Element end (14) features a contour including element top surface segment (36) extending horizontally to bend (38).
