These machines are essential for the textile and packaging industries, providing a reliable solution for coating applications. Featuring precision coating technology, our machines ensure high-quality results. Explore more about our equipment on the blogs section of our website.
Backing coating machines are complete sets of equipment that evenly apply molten plastic or hot-melt adhesive to the backside of substrates such as carpets, mats, paper, and films, imparting anti-slip, waterproofing, enhanced dimensional stability, or aesthetics. Depending on the coating material and the end product, mainstream models on the market can be categorized into three main types: PE/TPE/EVA car mat backing coating machines, PVC backing coating machines, and TPR/TPE carpet backing coating machines.
1. PE/TPE/EVA Car Mat Coating Machine
Applicable Materials: LDPE, EVA, TPE, or their foam blends
Product Specifications: Weight 300–1200 g/m², Web Width 1.5–2.6 m, Single- or Double-Sided Anti-Slip Texture Available
Core Configuration:
High-efficiency single-screw extruder (L/D 32–36) with melt pump and hydraulic screen changer, output 200–350 kg/h
Coat-hanger-style wide-width die head with built-in throttle bar, enabling online coating thickness adjustment from 0–5 mm
Three-roller embossing/cooling unit with interchangeable anti-slip textures (diamond, dot, fine straight)
Dual-station friction winding + automatic edge trimming for non-stop roll changes
Technical Highlights: Low-temperature plasticization maintains EVA expansion ratio; servo tension control prevents substrate deformation
Main Applications: Car driver's and passenger's floor mats, trunk mats, high-speed rail/yacht anti-slip mats
Applicable Materials: Soft PVC granules (containing plasticizer and CaCO₃), PVC paste resin, or hot melt adhesive
Product Specifications: Coating thickness 0.4–2.0 mm, web width 1.6–4.2 m, can be covered with mesh or foam
Core Configuration:
Large aspect ratio exhaust screw (L/D 34) with ceramic heating ring for uniform melt temperature, output 400–600 kg/h
Dual unwinding station with EPC automatic web correction; cloth storage rack ensures non-stop roll changes
Comma blade/roller coating lamination head with optional reverse roll or slot extrusion mode, surface flatness ±0.02 mm
Multi-stage hot air circulation oven (length 18–30 m), adjustable temperature 80–180°C, solvent residue ≤ 5 ppm
Cooling tunnel + embossing/printing unit + dual-station center rewind
Technical Highlights: Online thickness measurement and closed-loop control; optional UV curing or infrared preheating for increased productivity 20%
Main applications: Carpet tiles, commercial flooring, PVC wall coverings, brochure covers, and waterproof tarpaulins
3. TPR/TPE Carpet Back Coating Machine
Applicable Materials: TPR, TPE, TPV, or their foam pellets; 10–30% recycled rubber powder can be added.
Product Specifications: Backing weight 400–1000 g/m², width 2–5 m. Anti-slip textures, logos, or drainage grooves can be formed in one step.
Core Configuration:
Low-temperature, high-efficiency single-screw extruder (L/D 30–33) with melt pump and 2-zone die temperature control, output 300–600 kg/h.
Specialized "extrusion + embossing" integrated die head allows for micro-melt bonding of TPR and carpet pile at 200°C, with a peel strength of ≥30 N.
Three-roller cooling and shaping system; spiral flow channels within the rollers maintain a constant temperature of ±1°C. In-line non-woven or mesh fabric coating is possible.
Vertical and horizontal trimming + Fixed-length flying saws allow for direct palletizing or coiling of finished products.
Technical Highlights: No primer required, achieving anti-slip, waterproof, and soundproofing in one step; Line speeds of 5–15 m/min, 15% lower energy consumption.
Main Applications: Doormats, corridor rugs, artificial turf with adhesive backing, exhibition rugs, and anti-slip bathroom rugs.
Summary
Backing coating machines are developing towards "large-width, high-capacity, low-energy, and environmentally friendly hot melt adhesives."
Car mat back coating machines emphasize low-temperature plasticization and three-dimensional anti-slip patterns;
PVC back coating machines highlight multi-layer lamination, high-filling properties, and in-line embossing;
TPR/TPE carpet back coating machines focus on "one-step" anti-slip and waterproofing, as well as environmental friendliness and odorlessness, catering to the high-end carpet market in Europe and the United States.
