Abstract
Abstract A covering profile for structures is manufactured by pressing a non-swelling mixture of fibrous materials and thermosetting binding agent. The covering profile has an elongated body whose upper surface is provided with grooves extending parallel to the elongation of the body and being regularly spaced from each other. Associated to each groove in the upper surface are two countergrooves in the rear surface of the body. The method for manufacturing a so-shaped covering profile includes the prepressing in a prepressing tool having plane surfaces while the grooves and countergrooves are produced in the hot pressing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A plate-shaped covering profile for covering structures, said covering profile being pressed from a non-swelling mixture of fibrous material and a thermosetting binding agent, the covering profile comprising a one-piece elongated body having an upper surface provided with at least one upper groove extending transversely to the elongation of said body and having a predetermined contour, and a rear surface provided with at least two countergrooves each extending parallel to and located at a different respective side of said upper groove when projecting said upper groove on the rear surface of said body so as to form on said rear surface a bulge corresponding to the contour of said upper groove, so that said upper surface with at least one said upper groove and said lower surface with at least two said countergrooves have different shapes.
Claim 2
Dependent Claim
136 words
A plate-shaped covering profile for covering structures, said covering profile being pressed from a non-swelling mixture of fibrous material and a thermosetting binding agent, the covering profile comprising a one-piece elongated body having an upper surface provided with at least one upper groove extending transversely to the elongation of said body and having a predetermined contour, and a rear surface provided with at least two countergrooves each extending parallel to and located at a different respective side of said upper groove when projecting said upper groove on the rear surface of said body so as to form on said rear surface a bulge corresponding to the contour of said upper groove, so that said upper surface with at least one said upper groove and said lower surface with at least two said countergrooves have different shapes.
Claim 3
Dependent Claim
93 words
A covering profile as defined in claim 1, wherein said elongated body has a main portion and two end sections spaced from each other in longitudinal direction, at least one of said end sections being provided with a segment part arranged offset relative to the main portion of said body in longitudinal direction, said segment part being provided with an upper recess in the upper surface and extending transversely to the elongation of said body and with a rear counterrecess in the rear surface, said rear counterrecess extending parallel to said upper recess.
Claim 4
Dependent Claim
135 words
A covering profile as defined in claim 1, wherein said upper surface is provided with at least one further upper groove extending at a distance from said first-mentioned upper groove transversely to the elongation of said body and having a predetermined contour, and said rear surface is provided with at least two further countergrooves extending at a distance from said first-mentioned two countergrooves each parallel to and located at a different respective side of said further upper groove when projecting said further upper groove on the rear surface of said body so as to form on said rear surface a bulge corresponding to the contour of said further upper groove, so that said upper surface with at least two said upper grooves and said lower surface with at least four said countergrooves have different shapes.
