The large‑width rubber scraper gun delivers ultra‑wide one‑pass hot‑melt scraping coating for large‑format substrates. It adopts reverse‑suction internal flow channels to reduce residual glue stagnation and carbonization risk. Multiple independent scraper modules assemble on shared manifold, supporting segmented or full‑width treatment up to 700 mm total coverage. Dual Ni120 & PT100 sensors deliver accurate temperature control across 38‑230 °C, tolerating adhesive viscosity as high as 15 000 mPa.s.
Major benefits: replace multiple narrow slot guns to simplify piping layout; each scraper unit can be switched on/off individually to save adhesive for narrower workpieces. It bears peak glue pressure 90 bar and matches gear‑type or pneumatic hot‑melt hosts.
Main application fields: mattress full‑surface composite, hygiene‑product non‑woven lamination, large furniture veneer bonding, hard‑cover book and wide‑format filter processing. It is designed for roll‑to‑roll composite lines with heavy‑duty high‑viscosity hot‑melt coating requirements.
