TECHNICAL TEXTILES

Welding instead of sewing

With Leister heat guns and welding machines, posters, tents, covers, tarpaulins, sun protection and many other products made of thermoplastic coated fabrics can be processed and welded. With all these products, the edges of the panels are joined or hemmed together.

However, the individual fabric webs do not necessarily have to be sewn or joined with high frequency, but can be welded with hot air or hot wedges. Thanks to many years of experience and a high level of industry know-how, Leister is the global innovation and technology leader in the market. Developing groundbreaking and reliable equipment and machines for many different and unique applications in order to find optimal solutions for various textile applications is a priority at Leister.

Flexible Tank Welding
Compared to steel tanks, flexible tanks are comparatively light and portable, easy to store (can be folded) and require little effort to set up. They are robust and long lasting; ideal for use in demanding situations or those requiring a high degree of safety. This includes, for example, military purposes, or in the context of infrastructure, technical, sanitary or organizational emergencies, on construction sites, at harbors and more.

Welding Inflatables
Inflatable objects like boats, emergency slides, advertisements, bounce castles, sports equipment, balloons, mats, structures and even air domes. For objects that are filled with air, the absolute seam tightness must be guaranteed. Leister hot-air machines meet these requirements. Even with welding machines, Leister offers the possibility of tightly welding and bonding overlap seams, fillet seams and hem seams made of different film materials.
