Abstract

An elongate edging strip for trimming the edges of building panels such as tiles comprises an extruded profile made from a vinylaromatic homopolymer or copolymer. The profile comprises a leg section (1), intended to locate under the building panel and an upstanding section (2), both of solid material. The upstanding section (2) is turned inwards to form a groove containing a fillet (7) of foamed material. In an alternative aspect, a method of making an elongate edging strip is described, said method comprising extruding a profile comprising a base section and two spaced upstanding sections, forming a longitudinal line of weakness in the base section, and breaking the profile apart at said line of weakness to form two edging strips.

Claims

1. A method of making an elongate edging strip comprising, in profile, a leg section and an upstanding section, said method comprising forming by extrusion an elongate profile comprising a base section and two spaced upstanding sections, said base section being formed with a longitudinal line of weakness extending between said upstanding sections, and breaking the profile apart along the line of weakness to form a pair of said edging strips.

2. A method according to claim 1, wherein said extruded elongate profile is of a material selected from vinylaromatic homopolymers and vinylaromatic copolymers.

3. A method according to claim 2, wherein the material is styrene based.

4. A method according to claim 3, wherein the material is one of the group comprising polystyrene, polystyrene alloy and acrylonitrile butadiene styrene (ABS).

5. A method according to claim 1, wherein said base defines, with each said upstanding section, a groove which is filled with a fillet.

6. A method according to claim 5 wherein the fillets are co-extruded with the profile.

7. A method according to claim 5 wherein the fillets are formed of a foamed synthetic resin material.

8. A method according to claim 1, wherein the upstanding section is extruded in a shape that presents to the exterior a substantially planar front surface and a substantially planar top surface.

9. A method according to claim 1, wherein the upstanding section is extruded in a shape that presents to the exterior a curved surface.
