    Since the modern-day folding kayak, the option for skin construction was limited by the fabrics available. Stitching and gluing were the only means for joining skin sections. Since davison-machinery’s inception, the idea of High Frequency Welding a skin has been a davison-machinery dream.

    Working to davison-machinery’s specifications, our suppliers have come up with supple, robust urethane fabrics for our decks and hulls.

    The technology for welding urethane has been in place for quite some time. But with the recent development of a supple, robust urethane fabric, we’ve just now been given the fabric option we’ve been waiting for. Our goal was to make a skin-on-frame kayak that is completely dry. This has now been realized.

    Radio Frequency power is applied for a period of time to join polyurethane fabrics. The fabrics are held under pressure, coating to coating, with conductor dies.

    Davison worked with the equipment manufacturer and in our own shop to master this cutting edge technology. As heat is applied to two urethane fabric surfaces, they are pulled through rollers and bonded together. Temperature, speed and pressure are computer controlled.
