Chipboard panel edge reinforcing compact automatic system - injects strengthening agent in stages at intervals using gp. of successive nozzles w.r.t. edge length, for fireproofing

摘要

Reinforcement comprises injecting a strengthening agent into panels via individual nozzles. W.r.t. edge length, a gp. of successive nozzles is activated, to operate in stages. Injection at intervals equal to half that between the nozzles, is evenly distributed, and the agent used can be highly fire-resistant and free of formaldehyde, to form a fireproof door. ADVANTAGE - Compact and widely adaptable, avoiding manual adjustment. (8pp Dwg.No.1/3)
