Method of fabricating bitumen impregnated ridge tiles, and machines for fabricating them

A method of fabricating bitumen impregnated cellulose ridge tiles,

• each ridge tile having the general shape of a profiled ridge tile plate of cross-section that is symmetrical about a vertical longitudinal midplane,
• and that comprises a downwardly concave central ridge extended laterally on either side by a flat that terminates in a downwardly concave corrugation,
• said ridge tile further including a series of transverse ribs at each of its longitudinal ends,
• the method being wherein a shaped, dried, and bitumen impregnated cellulose panel is made, the panel being in the form of a section member of cross-section that is formed by juxtaposing at least two cross-sections, each identical to the cross-section of said ridge tile plate,
• with a series of transverse ribs being formed in the vicinity of both longitudinal ends of the panel and on either side of at least one virtual transverse separation line extending between the two longitudinal edges of the panel,
• and in that the shaped, dried, and bitumen impregnated panel is cut along a longitudinal line of cut situated between the juxtaposed ridge tile sections, between the corrugations of the ridge tile plates so as to form at least two ridge tile subassemblies, each including at least one ridge tile.
