Process for producing a thermobonding product by extruding a thermofusible mass (1) and scraping it in molten state onto an incised cylinder (2) regulated as to temperature between about C. and C., calendaring the mass (1) with this cylinder (2) and an elastomeric silicone cylinder (3), while transferring it onto the elastomeric cylinder (3), which simultaneously effects a consolidation of the product (1) by cooling. The product is then transferred either onto a conveyor band (4) and brought by the conveyor, after passage through thermal treatment zones (5), to a roll winding-up station (6), or directly, in the form of continuous or discontinuous structure, onto a final utilization or transfer support (17). The invention is particularly applicable in the field of the textile industry, particularly for bonding or reinforcing.
