Product Name
- Leister Variant T1 - Pressure Rollers (138.938 & 140.429)
Brief Description
- These are high-quality, ergonomically designed pressure rollers, essential accessories for Leister hot-air welding machines, particularly the Variant T1. They are used to apply consistent, uniform pressure during plastic welding processes to ensure strong, smooth, and wrinkle-free seams on various thermoplastic materials. These rollers are crucial for achieving a professional finish by pressing down materials for a secure, even bond.
Popular Applications & Uses
- Plastic welding projects, including overlap, hemming, and pipe welding.- Repairing and fabricating tarpaulins, banners, and signs.- Smoothing edges and ensuring adhesion in roofing and flooring installations.- Civil engineering and geomembrane welding projects.- Welding technical textiles and industrial fabrics, such as commercial vehicle side curtains, boat covers, and marquee repairs.- Laminating and creating custom seals.- Waterproofing applications for roofs and swimming pools.
Industries that Commonly Use It
- Construction/ Building Services- Tarp, Fabric, Awning Manufacturing- Sign & Display- General Manufacturing- Plastic Fabrication- Cladding- Automotive Service/Repair- Marine- Pool/Spa/Plumbing
Special and Unique Features
- Ergonomic design for comfortable handling during extended use.- Sweat-absorbent design feature to reduce slippage.- Engineered to reduce operator exertion, with the rollers taking on more of the burden.- Available in various widths and materials to suit different project requirements.- Equipped with ultra-smooth action bearings for consistent pressure application.- Durable construction, often with wooden handles for excellent grip and comfort, particularly in low temperatures.- Bow shape design suitable for both left and right-handed operators.
Key Properties
- **Material:** Commonly silicone (50 shore A), but also available in stainless steel, brass, and PTFE.- **Function:** Applies uniform and consistent pressure to weld seams.- **Durability:** Built for longevity and professional use.- **Precision:** Essential for achieving clean, professional, and wrinkle-free finishes.- **Temperature Resistance:** PTFE rollers offer more temperature resistance than brass, preventing damage to membranes.
Surface Compatibility
- PVC (Polyvinyl Chloride) tarpaulins, banners, and membranes.- PP (Polypropylene) tarpaulins and membranes.- PE (Polyethylene) tarpaulins and membranes.- Thermoplastic membranes (e.g., TPO).- Industrial fabrics and technical textiles.- Geomembranes.
Known backups / known substitutes
- Other Leister hand pressure rollers of varying widths (e.g., 8mm, 16mm, 28mm, 40mm, 80mm) and materials (silicone, brass, PTFE, steel).- Specific Leister rollers like the 140.160 (40mm silicone pressure roller) or 140.161 (28mm silicone pressure roller).- Replacement silicone sleeves (e.g., 140.599) for existing rollers.- Rollers from Leister's subsidiary brand, Weldy, may offer similar functionality.
Comparison Note
- Leister pressure rollers are distinguished by their high-quality construction, ergonomic design, and precision engineering, which contribute to superior weld seam quality and reduced operator fatigue compared to generic alternatives. They are specifically designed to complement Leister's range of hot-air welding tools, ensuring optimal performance and durability for demanding professional applications.
