Welding Acrylic Fabric with the UNIPLAN and De-reeler

Items Required:

• UNIPLAN E automatic welder
• De-reeler accessory
• Heat activated adhesive tape
• 2 pieces of acrylic fabric (e.g., Sunbrella)

Procedure:

1. Install the de-reeler onto the UNIPLAN and the 3M adhesive tape onto the de-reeler spool. A copy of the installation instructions can be found here and are included with purchase of the de-reeler.  
   
   
2. Lay out the material to be welded. Place the two pieces one on top of the other, face side together aligning the edge to be welded. Secure both pieces of material with tape or weights to prevent movement during welding. 
   
   
3. Use the trolley lever to raise the UNIPLAN and position the tool. The body of the UNIPLAN should be on top of the fabric with the nozzle positioned so it can swing down and under at the edge of the fabric. The de-reeler arm should be positioned between the two pieces of fabric.
   
   
4. Run the adhesive tape through the de-reeler under the drive wheel of the UNIPLAN, pull the tape through at least 6 to 8 inches passed the drive wheel. This should sandwich the adhesive tape between the two pieces of acrylic fabric. 
   
   
5. Lower the UNIPLAN (using the trolley lever) making sure both the UNIPLAN’s drive and guide rollers are properly aligned along the edge of the material. 
   
   
6. Turn on the UNIPLAN. 
   
   
7. Set the proper temperature, speed, and airflow parameters according to the adhesive tape type and thickness of acrylic. This step will require experimentation and testing to determine the correct settings. See our article on Choosing Welding Parameters for more details. 
   
   
8. Move the welding nozzle down and slide inward completely under all three pieces of acrylic and adhesive tape. This will activate the drive of the UNIPLAN. 
   
   
9. As the UNIPLAN starts moving carefully guide it along the welding seam making sure all edges of acrylic fabric and adhesive tape are in line with the drive and front guide wheels. 
   ​
10. After completion inspect the weld by performing a tear test. If the weld is not satisfactory adjust the parameters accordingly and repeat the procedure.
