The charge-end of Antonini Annealing Lehrs is composed of:
• A roller, manufactured using anti-deformation techniques, fitted onto a support system that self-compensates elongation due to the temperature. 
• An efficacious albeit simple support system that keeps the belt from sagging between the roller and the sliding bed of the first module of Tunnel.
• One or more insulated “sandwich” doors, which can be raised manually or by motor, to reduce heat dispersion. Solutions with pneumatic doors, used for hand charge, are also available.
• A front hood, which can be provided on request.
