Preservation Equipment Ltd’s polyester sealing machines are recognised and trusted worldwide. After years of experience with the previous Crossweld we have now introduced the ultimate sealing machine. This new machine has been designed with health and safety approval, we no longer use a foot switch which could easily be activated by accidentally stepping on it (health and safety liked that). The jaws previously slammed down by touching the foot switch and could cause nipping of fingers, this cannot happen with this new machine. Not using jaws means you are not restricted by the jaw width and can continually weld very wide sheets, up to a maximum of 1400mm. The new style of operation allows much more room to work with the material you are sealing. We have increased the weld length to 700mm and you are no longer restricted to the width between the jaws as on the old machine. For wider material you can now continuously weld in any position from the edge to the centre, this is because the jaws are no longer used.
