SED-1100JDJ-R — Revestidora de fita adesiva

Substrate paper unwinds from one of two unwind stations (3" air shaft, 76 mm core, 100 N·m magnetic powder brake, electric loading + auto web steering). Block hot-melt adhesive is loaded into the 150 kg aluminum tank and heated by cast-in heaters in three independently PID-controlled zones (max 230 °C). A high-temperature gear metering pump (VFD-controlled) feeds adhesive through a 3 m PTFE-cored heated hose (1200 W trace heat) to the alloy steel coating head. The blade-coating head dispenses adhesive onto the substrate via internal flow channels with multiple local-zone temperature and flow valves; substrate passes through a Φ215 mm chrome-plated steel coating roll backed by Φ215 mm silicone composite roll (water-cooled, dynamically balanced). The web then passes through the engraved perforation roll (Φ215 mm, oil-cooled) against a silicone backing roll, then to one of two rewind stations (3" air shaft, 76 mm core, dual 100 N·m magnetic powder clutches). Touchscreen (Delta) and Inovance VFDs synchronize coating-head and main drive speeds. Pneumatic cylinders (AirTAC, Φ100 mm × 2) lift the coating head and composite roll for substrate threading.
