The PQ-18 is a simple and cost effective tool for welding of Polycord round belts. The joining operation is by blunt welding: Ends of the belt are melted by pressing them against the surface of a precisely regulated hot welding plate. After sufficient heating belt ends are pressed against each other with a defined pressure and left to cool in a defined position. After removing the resulting bead with a knife or by grinding an optimum quality round belt is ready for use.
The PQ-18 is well suitable for on-site installation and small to medium size series fabrication in the workshop.
