Product Name
Leister (156.472 & 157.879) Hem and Piping Guide for Hemtek
Brief Description
These are specialized accessory guides designed for the Leister Hemtek ST stationary hot-air welding machine, enabling precise and efficient creation of hems, pole pockets, and piping on various thermoplastic industrial fabrics. The guides facilitate tool-free adjustment and are available in two main variants: 156.472 for light and medium materials, and 157.879 for heavy and thick materials.
Popular Applications & Uses
- Creating hems on banners, billboards, and promotional materials.- Forming pole pockets for banners and signs, up to 100 mm (4 inches).- Welding piping into fabric seams (keder welding).- Fabricating tarpaulins, tents, awnings, and protective covers.- Producing textile roofing and facade elements.- Manufacturing truck tarpaulins.
Industries that Commonly Use It
- Tarp, Fabric, Awning Manufacturing- Sign & Display- Plastic Fabrication- Construction/ Building Services- Transportation/ Specialty Vehicle
Special and Unique Features
- Tool-free adjustment and changing of guides on the Leister Hemtek ST machine, enhancing ease of use and productivity.- Designed for specific applications: hem welding, pole pocket creation, and piping insertion, offering a 3-in-1 functionality with one guide.- Available in variants optimized for different material thicknesses (156.472 for light/medium and 157.879 for heavy/thick materials), ensuring versatility across various projects.- Enables high-quality, consistent, and strong welds when used with the Leister Hemtek ST, contributing to durable end products.- Contributes to a streamlined, single-step welding process, eliminating the need for additional preparation or finishing with hot-air hand tools.
Key Properties
- Accessory for the Leister Hemtek ST hot-air welding machine.- Facilitates precise material guidance during the welding process.- Constructed for durability and industrial use.- Specific models cater to different material thicknesses: 156.472 for light/medium and 157.879 for heavy/thick materials.- Enables various seam types including closed hems (20/30/40 mm), open hems up to 100 mm, pole pockets, and hems with rope/piping.
Surface Compatibility
- Compatible with a wide range of thermoplastic materials, including PVC, PE, PP, and other coated technical textiles.- Suitable for welding membrane liners, foils (with or without reinforcement), and homogenous or coated PVC-P, ECB, EPDM, CSPE, and PE.- Not recommended for natural fibers such as wool and cotton, as these materials do not melt under heat to form molecular bonds.
Known backups / known substitutes
- Other specialized guides for the Leister Hemtek ST, such as overlap seam guides (e.g., 155.800) or tape welding guides (e.g., 159.780), for different welding applications.- Alternative industrial fabric welding methods and machines, including hot wedge welders (e.g., Miller Weldmaster Triad), ultrasonic welding, radio frequency (RF) welding, or solvent welding, depending on the specific material and application requirements.- Traditional sewing methods, although these typically offer less strength, durability, and water resistance compared to welded seams for industrial fabrics.
Comparison Note
These Leister Hem and Piping Guides, when used with the Leister Hemtek ST hot-air welding machine, provide a highly efficient, precise, and automated solution for creating specific seam types (hems, pole pockets, and piping) on thermoplastic fabrics.- Compared to manual hot-air welding or traditional sewing, this system offers superior consistency, speed, and weld quality, resulting in seams that are often stronger, more aesthetically appealing, and highly resistant to weathering and tearing.- The tool-free adjustment and specialized design for different material thicknesses significantly enhance productivity and versatility for fabricators working with a variety of industrial textiles.
