VORRICHTUNG ZUM VERSCHWEISSEN VON PROFILEN AUS THERMOPLASTISCHEM KUNSTSTOFF

摘要

The ends of thermoplastic profiles to be joined are placed into contact with a heated element so that the thermoplastic material will be softened. During this softening the outward displacement of the thermoplastic material beyond the outer contour of the respective profile is prevented. Upon softening the ends are moved out of contact with the heated element and are placed into abutment with one another. During the subsequent hardening of the softened material outward displacement beyond the outer contour of the profiles is again prevented.
