摘要:
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.

摘要:
An automobile glazing pane, ready for installation, is pre-equipped with a mounting frame of an elastomer. The mounting frame is disposed only on the side of the glass pane facing towards the fixing flange of the window frame, without engaging around the edge of the glass pane and is bonded to the glass pane. It possesses a mounting groove for the clamped fixing of the pre-equipped glass pane to the fixing flange of the window pane.

摘要:
A thin film for covering a clear or colored glass sheet to form a monolithic automobile glazing. The film is based upon metallic tantalum. It may be covered with a layer based upon oxides of various metals. The solar energy transmission and also the reflection of light through the glazing are low, whereas the reflectance is similar to that of the base glass.

This invention relates to a pane comprising a glass substrate (1) coated with at least one transparent, thin, low-emissivity and/or conducting "functional" film (3), and with an "intermediate" film (2) disposed between substrate (1) and functional film (3). The intermediate film (2) has an optical thickness between 150 and 195 nm, preferably at approximately 168 or 185 nm, so that the residual color of the reflected appearance of the substrate from the "film side" of the pane is in the range of the blues.
摘要:
A method of and a device for curving glass sheets preheated to curving temperature operate by passage of the glass sheets simultaneously over a principal shaping bed having a longitudinal trajectory which is substantially circular or substantially a cone of revolution, and one or more secondary shaping beds, the generatrices of which are inclined relative to those of the principal bed. The invention is applicable, notably, to the production of automobile panes having angled corners.
摘要:
A pulverulent organometallic compound containing tin and a halogen, notably fluorine, is pyrolyzed by heating on the surface of a transparent substrate, notably of glass, in order to form a film of tin oxide doped with a halogen. The coated substrate has improved infrared radiation and/or electrical properties. The granulometry of the organometallic compound is chosen such that the diameter of the particles d.sub.90 is between 40 and 200 microns.
摘要:
Tubular coverings for conveyor rollers for glass sheets heated to the softening point in a bending and/or heat treatment furnace, which have the special feature of having an outer surface, i.e. the surface that contacts the glass sheets, which is based on metal wires exhibit a reduced risk of marking the glass sheets and also exhibit a high temperature and wear resistance. Such tubular coverings are preferably used for covering the rollers present in the frontal and/or lateral positioning zones of the glass sheets on the conveyor.
摘要:
For the extrusion of a calibrated profile of a thermoplastic polymer onto articles, the polymer, which is melted in an extruder (17), is fed, via a heated pressure hose (22), to an extruder head guided by a robot (5) and, by means of said extruder head, extruded and deposited on the article. At the end of each extrusion operation, the material flow to the extruder head is maintained and, by means of a change-over valve within the extruder head, redirected into an outlet orifice provided in the vicinity of the die orifice until the commencement of the subsequent extrusion operation. The redirected material flow emerges from a pipe connector (29) which is arranged on the extruder head and is coupled to a coupling piece (33). The material collected in this manner may be pelletized and fed back to the feed hopper (16) of the extruder (17).
