Abstract: The belt is of those which have a flat configuration and is closed by means of staples (6) or similar. Said belt comprises a mesh fabric (1), with warp (12) and weft (11), in which a plurality of holes (2) of size and determined density are defined, said fabric (1) being covered and thermofixed by a coating (3) of nonslip and temperature-resistant material. The weft (11) has some reinforced areas (4) alternating with some clearer areas (5), in which the weft (11) has a lower concentration of threads or fibres and, jointly with the warp (12), it defines the holes (2). The invention includes a method of manufacturing said belt (1).
