ABSTRACT:
A method and apparatus for extruding a plastic spacer directly on an object, in particular on the periphery of window glazing, such as automobile glazing intended to be glued into the opening of a vehicle. In particular the invention relates to properly producing the connection zone between the end and the beginning of the extruded spacer when it forms a closed loop. According to the invention the beginning of the spacer and the remainder of the loop are extruded, with the exception of the connection zone. The object is then provided with an applied anti-adhesive deposit surface that is continuous with the surface of the object. The path of the extrusion head is diverted in relation to the surface of the object so that the extrusion occurs on the applied deposit surface, proximate to and beyond the beginning of the spacer loop. The extruded spacer is then allowed to harden and the extremities of the spacer are cut and adjusted to properly complete the connection. After extrusion, the applied deposit surface may be eliminated or neutralized and the spacer, whose path was diverted on the surface of the object, is glued in position to complete the connection zone.
