321-big

After a decade of experience in designing and building heavy duty welding and cutting machines to process flexible PVC we introduced SM-321-HA, a multiple tool digital welding station for the full-automatic production of tarpaulins, truck covers and roofs, and pergolas.

SM-321-HA caused a revolution in the truck cover industry by drastically reducing the necessary cycle time and number of operators needed for the job. Since its introduction in 2010 the machine has seen several upgrades that make it the fastest, most efficient manufacturing solution for quality tarpaulins available on the market today. With its unparalleled welding quality and exceptional productivity, its wide variety of cutting and welding tools and accessories, SM-321-HA is a machine unlike any other on the market.

A range of specifically designed software programs make SM-321-HA a complete manufacturing solution for your production requirements. It will streamline your production processes and deliver the efficiency and quality you are looking for.

INDUSTRIAL WELDING AND CUTTING TOOLS

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.

Main features

Continuous production cycles

The industrial, heat resistant conveyor belt enables the machine to perform a continuous pull-and-weld operation and work in full automatic cycles. The vacuumed belt and pneumatic rollers pull the fabric off of the roll, the welding, marking and cutting tools do their job until the programmed sequenced is done or until the fabric on the roll finishes.

High speed welding. Exceptional productivity

With its continuous production cycles the machine is able to create one cover after another, and only stops when the fabric on the roll finishes. The high power vertical welding heads allow for great welding speed and drastically reduce the necessary production time.

High level of automation

Only one operator is needed to supervise the machine during the welding cycles. Instead of needing multiple operators for the multitude of cutting and welding jobs necessary to produce a truck cover, SM-321-HA carries out all steps in the process automatically.

Creation of very large shapes in a limited space

With its continuous fabric feeding operation, the industrial conveyor belt allows for the creation of very large patterns in a very limited space. End products of infinite length can easily be created by this machine with very limited footprint.

Heavy duty industrial structure

The exceptional manufacturing performance of SM-321-HA series stems from the symbiosis of superior control systems, a very robust machine structure and components, precision mechanics and highly reliable welding tools. With its sturdy, heat resistant, multiple-layer conveyor belt, SM-321-HA will apply straps in X and Y direction on PVC panels of infinite length. Top of the bill electronic and pneumatic components, high precision tools, and an industrial unwinding system for jumbo rolls complete this machine.

Highly customizable

Whether you first apply a vertical or a horizontal strap, whichever the size of the straps is, whether you apply a specific profile or need to weld a pocket or a hem, SMRE can build the structure, the tools, and the accessories to fit your specific production requirements and allow you to create the end products you desire.

Extremely small tolerances even on great lengths

With its vacuumed conveyor belt and its motorized unwinder with electronic edge correction and digital fabric tension control, straps are applied with absolute precision and the length tolerance is close to zero.

Unparalleled welding quality

The smooth, digitally controlled fabric feed and the patented Intelligent Torque technology on the welding wheels ensure a superior welding quality during the application of all straps – whether these are standard PVC or anti-vandalism profiles with steel cables, or omega profiles for pergolas – in X and Y direction.

SOFTWARE SOLUTIONS

SOFTWARE SOLUTIONS

SM-321-HA is managed with an easy-to-use software that is operated from a touch screen control panel. The machine imports and reads CAD drawings of the finished product, translates the drawings into welding jobs and sets all vital parameters automatically. To further automate the production cycle, a barcode reading system is available that avoids unskilled operators from having to program the machine. All the operator has to do is point the gun at the barcode, place the material on the conveyor belt, check the correct positioning of the tools, and push the START button.
