摘要 |
In order to produce a packing ring having a stiffening ring by a method which dispenses with the use of a complicated and expensive mold, an extrusion having the desired cross-section of the packing ring and having a cavity, extending in the extrusion direction, for the reception of the stiffening ring is firstly produced. The extruded material cut to length in accordance with the desired circumference of the packing ring is slipped onto a wire which is similarly cut to length and bent into a circle. The ends of the extruded material are pushed back while the ends of the wire are welded together, so that a closed stiffening ring is produced. Then the material ends are joined together and are bonded or vulcanized to one another. |
