Machines and equipment designed for assembly processes, for joining the front sides and linings or for reinforcing and consolidating parts of manufactured items, can operate either cold or hot - in this last case, for instance, intervening on semi-finished articles treated with thermo-adhesives or polyurethane cements to reactivate them. From a structural and operative point of view, the feature of the machines can be: rotary plates, or alternatives, with a vertical pressing movement; plates hinged along one side and with a folding door construction; presser roller with continuous feed.
