Abstract
The invention relates to a glass fibre-reinforced, extruded plastics material hollow profiled strip for the production of window frames, glass doors, or the like. In order to be able to butt-weld profiled strips of this type together when producing the frame and to ensure a reliable bonding between the glass fibres and the plastics material of the profiled strips a synthetic resin is used as the bonding agent which causes this bonding, which synthetic resin has thermoplastic or thermoelastic properties and thus enables the glass fibres to be deflected during butt-welding and pressing together of the ends of the frame pieces.
Claims13
Extruded plastics material profiled strip for butt-welded window frames, said strip having a profile body with profile walls forming a longitudinal chamber and consisting at least essentially of a thermoplastics material, at least one profile wall being provided with a reinforcement element which is integrally connected to said profile wall, characterized in that the reinforcement element consists of reinforcement fibres bonded to each other by a synthetic resin cement selected from the group comprising synthetic resins having thermoplastic properties and synthetic resins that manifest thermoelastic properties at the welding temperature of said profile walls so that the reinforcement fibres can be deflected during butt-welding, and said reinforcement element being continuous and separate from said thermoplastic material forming said profile walls and said reinforcement element extending along said profile wall throughout its length.
