1. An apparatus for thermo-forming and/or thermo-adhesive bonding of semi-finished products,
wherein the apparatus is configured for heating semi-finished products provided with thermo-plastic or thermo-adhesive elements, so as to determine an at least partial melting and a subsequent cross-linking of thermoplastic polymers of said thermo-plastic or thermo-adhesive elements, and
wherein the apparatus comprises:
an oven having walls delimiting a chamber configured to house at least one semi-finished product, the walls comprising a pair of lateral internal walls extending vertically on opposite sides of the chamber;
devices for generating a flow of heated fluid in the chamber, wherein at least one of the lateral internal walls of the oven has a plurality of openings in fluid communication with said devices; and
baffles and closing elements mounted on a face of the at least one of the lateral internal walls near at least some of the plurality of openings;
wherein the baffles are configured to divert the heated fluid leaving the plurality of openings into the chamber and wherein the closing elements are configured to obstruct some of said openings,
wherein the baffles and the closing elements are replaceable, in order to change conditions of the flow of the heated fluid in the chamber,
wherein the apparatus further comprises a plurality of coupling elements arranged on the face of the at least one of the lateral internal walls and wherein the baffles and the closing elements are hooked in a removable way to said coupling elements,
wherein each of the coupling elements comprises a lamina arranged parallel to the face of the at least one of the lateral internal walls, the lamina defining a pocket configured for housing a portion of the baffle or the closing element, and
wherein the portion of the baffle or of the closing element is slidably insertable in the pocket or slidably removable from the pocket.
