Method and apparatus for butt-jointing profiles made of elastomeric material

Abstract

A process for butt-jointing profiles or profile sections made of elastomeric material including providing profiles having cut surfaces in jointing areas, moving the profiles toward each other leaving a bonding gap between the cut surfaces, introducing a jointing material into the bonding gap, and moving the profiles even closer together until their cut surfaces come into bonding contact with the jointing material. The jointing material is introduced directly into the bonding gap in a viscous state, preferably extruded into the bonding gap as a film. An apparatus for butt-jointing profiles or profile sections including a pair of clamps that can move toward each other and for receiving the profiles, and an extruder having an extruder die positioned to introduce jointing material into the bonding gap between cut surfaces of the profiles.
