Several techniques or combination of techniques enable the production of fabric expansion joints. Which way of production is chosen depends on:

1. The application of the expansion joint
   - e.g. is 100 % air- or liquid tight required?
2. What material of construction is required.

Laser en cutting techniques

• Automated unwinding and cutting of fabric (with pizza or rotating knife);
• Automated cutting of fabric using a laser cutter (cutting table 3 x 15 meter).

Sealing techniques

Buitink Technology uses all kinds of possible techniques to seal and combine canvas, foils and fabric to make sleeves and fabric expansion joints.

Amongst others these techniques are:

• Stitching and sawing with standard (polyester) cotton yarns, but also PTFE, glass fiber and Tenara yarns. Several types of sewing machines we have available: zigzag stitch as well as free-arm.
• High frequent welding(HF welding)
• Ultrasonic welding;
• Hot air welding;
• Seamtec welding;
• Miller welding;
• Gluing;
• Clamping;

below you find pictures of several bonding techniques we use in our production facilities.
