The New UNIPLAN 300 Industrial Fabric Welder from Leister Welds Tarpaulins, Banners, Tents and PVC Coated Materials

The all new UNIPLAN 300 technical textile and industrial fabric welder from Leister has been radically redesigned to make it faster (up to 16m/min), easier and more intuitive to use. It now also comes with the ability to weld up to 40mm seams.

Leister has an enviable reputation for designing industrial quality machines and this is especially true when it comes to welding PVC coated or reinforced materials such as those used in making PVC banners, lorry tarpaulins, manufacturing marquee’s or inflatable structures such as tennis domes or sports hall coverings.

For flexibility the machine is also suitable for floor or bench top operation. The UNIPLAN 300 comes with an automatic swivel-in control for the nozzle (controlled at the rear of the machine) to make it safer, easier and more reliable for the user. There is also an option for an integrated material lifter for tarpaulins etc. 

In addition, the introduction of a cleverly designed sliding swivel caster that can be moved out of the way of obstacles like grommets, hooks or other accessories that may otherwise cause an issue with the welding process.

Faster production processes are now achievable as the UNIPLAN 300 can quickly be changed from overlap welding to pipe or hem welding in one easy step. In addition, the introduction of an adjustable starting delay / preheat means the welding process can be accurately adapted for light or heavy materials.

A cost effective and simple to install upgrade is the option of an integrated weight section directly over the pressure wheel. This then allows additional (optional) weights (2 x 1.25kg) to be added to adjust the welding pressure.

An additional extra is a rotatable handle for ease of lifting and guiding. A longer handle is also available as an additional optional extra. As with all the latest Leister automatic welding machines the UNIPLAN 300 is digitally controlled.

Whilst it doesn't have the more sophisticated E-Drive system of it's larger brother, with it's ability to store welding parameter settings, the UNIPLAN 300's digital control interface allows the adjustment of drive speed, blower speed and temperature.

All control settings are closed loop for accurate welding. It also comes with a low-maintenance brushed motor.
