Main features

With its multiple welding technologies SM-216-SA can bond an infinite range of specialty fabrics. Operators can choose from a variety of accessories to make overlaps, hems, pockets, pockets-with-rope or cable, or apply zippers, keders, extruded profiles, omega-profiles or reinforcing straps. Guides, welding wheels and other tools are tailor-made according to your production requirements and allow you to fully customize the finished products you create.
The patented Intelligent Torque technology and the floating welding wheels ensure that seams made with SM-216-SA are of unparalleled quality, both aesthetically and in strength. SM-216-SA is a must-have to create unique, highly professional products.
Its solid structure makes the machine suitable for the most challenging welding work. All machine components are in solid steel and aluminum. Top of the bill electronic and pneumatic components and precision welding tools and accessories make this machine the best available on the market. SM-216-SA has a standard usable length of 6,0 meters. Extension modules of 2,0 m each make the machine as long as required. To weld XXL panels, the machine is available in a version with increased work surface (SM-210-SA).
Motion is generated by steel rack-and-pinion transmission and multiple heavy duty chrome plated rails for optimal speed and control. Whether you make overlaps, hems or pockets or apply omega or other profiles, SM-216-SA will deliver the quality you expect.
A series of specific parameters can be chosen from the touch screen to create the ideal setting for every type of fabric or application. Multiple operational menus can be stored in the machine’s computer. Each menu can be given a specific name so that the operator only has to choose the menu most suitable for the fabric or application at hand and the machine will set the parameters by itself, allowing even unskilled operators to create superior products with this highly professional digital welder.
The welding wheels have to exert exactly the right pressure. If the pressure is too high, the seam will show the imprint of the wheels. If the pressure is not high enough, the weld will lack in strength. The SMRE welders install floating wheels whereby the pressure is determined pneumatically, not mechanically. By adjusting the pneumatic pressure, the upper wheel will “float” over the seam, and exert exactly the same pressure on the fabric during the whole cycle, even when the wheel encounters an overlap or other obstacles in the fabric.
The fabric is spread and clamped on the worktop. All the operator has to do is choose the right menu for the application at hand and push the START button. The Intelligent Torque technology pulls the fabric under exactly the right tension. The welding head travels the full length of the fabric until the clamps open at the end of the cycle and the product is ready.


SMRE offers a wide selection of industrial tools: they can be installed individually or simultaneously, in a variety of combinations, providing an enormous versatility of applications.

Ensures high quality bonding in terms of strength, precision and aesthetics. As opposed to technologies such as impulse and high frequency (HF), hot air welding does not produce any heat stress and only affects those sides of the material that are bonded together. Since the inner part of the fabric is not affected by the heat in any way, its physical and aesthetic properties remain intact. In combination with the patented Intelligent Torque, hot air welding technology avoids puckering of the fabric and fading or altering of the colors, and ensures seams of superior quality. The technology is commonly used on PVC or PVC coated fabrics and gives excellent results when used to weld glue coated zippers to fabrics or to apply glue tape to bond acrylic and polyester.
Hot melt (liquid glue)

Liquid glue technology is used in place of conventional sewing with needle and thread and guarantees incomparable strength, durability and aesthetical results when used on textiles like acrylic and polyester. Besides a significant aesthetical improvement, the liquid glue bonding process ensures waterproof seams since it does not puncture the fabrics (as happens with sewing needles). Tests carried out by independent laboratories show that liquid glue accounts for an increase in durability of up to 60% compared to traditional stitched seams. SMRE was the first manufacturer in the world to develop a system to glue textiles for outdoor awnings. Today, our customers have welded more than 14 million meters of fabric, making our liquid glue system the undisputed champion in glue bonding of technical fabrics. Liquid glue is suitable to bond uncoated acrylic and polyester fabrics. For Teflon coated and other hard-to-weld fabrics, a specifically developed system for polyurethane glue is available.

Besides the usual parameters installed in welding machines built by other manufacturers – speed of the welding head and of the wheels, temperature of the air or of the glue, pressure of the wheels on the fabric – SMRE added another parameter: Intelligent Torque. Intelligent Torque is the force with which the wheels pull the processed fabric under tension during the welding cycle. Fabric tension is of fundamental importance to guarantee high quality seams. If the tension is too high, the fabric tends to stretch during the weld and shrink after the welding process, causing wrinkles in the seam. If the tension is not enough the fabric tends to run out of the guide, compromising the precision of the seam. By digitally controlling the tension in the processed fabric, the patented Intelligent Torque technology guarantees seams of the highest quality, both aesthetically and in terms of strength.
