Product Name
Leister (140.771 & 141.558) Variant T1 - Overlap & Hem Heat Nozzles
Brief Description
These are specialized heat nozzles designed for the Leister Variant T1 automatic hot air welding machine, enabling precise and efficient overlap and hem welding of various thermoplastic industrial fabrics.
Popular Applications & Uses
- Welding of truck tarpaulins and lorry side curtains.- Fabrication of advertising banners and large format signs.- Production of tents, marquees, and awnings.- Hemming and pole pocket creation for industrial textiles.- Welding of flexible tanks and plastic fabric hoses.- Protective cover welding.- Textile roofing and facade welding.- Pool waterproofing.
Industries that Commonly Use It
- Tarp, Fabric, Awning Manufacturing- Construction/ Building Services (specifically for roofing and facade applications)- Plastic Fabrication (for flexible thermoplastic materials)- Sign & Display- Cladding (for textile roofing and facade welding)
Special and Unique Features
- Designed for precise overlap and hem welding.- Available in specific widths (20mm - 140.771 and 40mm - 141.558) for varied application requirements.- Optimized for use with the Leister Variant T1 automatic welding machine, ensuring high welding speeds (up to 18 m/min or 59 ft/min) and consistent quality.- Process-optimized nozzle design for wrinkle-free welds.- Made from durable materials for professional use.
Key Properties
- Material: Typically stainless steel for high-temperature resilience.- Welding Widths: 20mm (140.771) and 40mm (141.558).- Compatibility: Specifically designed for the Leister Variant T1 automatic welder.- Heat Resistance: Capable of withstanding high operating temperatures required for hot air welding (e.g., 400-730°C / 700-1350°F).- Durability: Sturdy build for professional and industrial use.
Surface Compatibility
- PVC (Polyvinyl Chloride)- PP (Polypropylene)- PE (Polyethylene)- TPO (Thermoplastic Polyolefin)- ECB (Ethylene Copolymer Bitumen)- EPDM (Ethylene Propylene Diene Monomer)- CSPE (Chlorosulfonated Polyethylene)- Various coated industrial fabrics and technical textiles.
Known backups / known substitutes
- Other Leister overlap and hem welding nozzles of different widths or designs.- Nozzles for other Leister hot air tools like TRIAC ST, TRIAC AT, DIODE for manual welding applications.- Hot wedge welding machines for industrial fabrics, which use a heated ceramic wedge instead of hot air.- RF (Radio Frequency) welding, another method for joining coated fabrics.- Hot bar welding, using a heated metal bar.
Comparison Note
- These nozzles, when used with the Leister Variant T1, offer significantly higher welding speeds (up to 18 m/min) compared to manual hot air welding tools, increasing productivity for large-scale fabrication.- They provide consistent, high-quality, and wrinkle-free seams, often stronger than the base material, which is crucial for durable industrial products like tarpaulins and banners.- The precise heat and pressure application of hot air welding, facilitated by these nozzles, creates homogeneous, waterproof bonds without the need for adhesives or stitching.
