  • Method for the manufacture of a weather strip for motor vehicles
    Patent number: 4765936
    Abstract: The method enables the manufacture of a weather strip including a profiled section with a cross-section in the form of a web terminating in a head, the extent of the web being variable between a minimum value and a maximum value. For this purpose, an extrusion is formed which includes a tab part having a transverse extent greater than the maximum value: immediately the tab has been extruded, it is divided into first and second flows of extruded material; the section of the first of these flows has an area at least equal to the area of the section of the profiled section of the weather strip to be manufactured. The proportions into which the tab is divided in the two flows are altered in dependence on the advance of the extrusion, in correspondence with the variations in the transverse extent of the web of the profiled section it is desired to produce.

  • Method for the continuous extrusion of an extrusion, particularly a weather strip for motor vehicle bodies
    Patent number: 4584150
    Abstract: The method consists of:providing an elongate member (tracer) of a material which is substantially inextensible or extensible to a foreseeable extent,feeding the member to the extrusion head of an extruder simultaneously with the material to be extruded so that the member is incorporated in the extrusion during extrusion,detecting the advance of the member upstream of the extrusion head, andsynchronizing the operation of adjusting means operable to modify the section of the outlet orifice of the extrusion head with the advance of the member.The invention also relates to apparatus for carrying out the method.

  • Extruded weather strip for motor vehicle bodies and an extrusion head for forming the weather strip
    Patent number: 4531326
    Abstract: The weather strip is intended to be applied to the edge of an aperture or closure element of the body of a motor vehicle and comprises an anchoring section of elastomeric material with a channel section, and a tubular sealing section also of elastomeric material coextruded with the anchoring section. In the portions of the weather strip intended to be applied to corner portions of the edge of the aperture or closure element, or to portions of the edge close to which there are obstacles, the tubular sealing section is curved relative to the anchoring section and is connected to the anchoring section along a curved line.The invention also relates to an extrusion head for extruding a weather strip of the said type.
