Sealing or finishing strips and carriers therefor

A carrier for a channel-shaped trimming or sealing strip is manufactured by leading a main wire between meshing teeth so as to give the wire a zig-zag configuration. The emerging wire is pushed between guide walls. Simultaneously, looped edge wires are fed in, along the walls, and mesh with the ends of the loops of the main wire. The meshed wires are fed into the mouth of a cross-head extruder. This extrudes plastics or rubber material around the meshed wires so as to hold them in meshing engagement. The resultant generally flat strip can then be bent into channel-shape. |
|
DETAILED DESCRIPTION What is claimed is: 1.
A trimming or sealing strip, comprising a carrier for reinforcing the strip and covering material in which the carrier is completely embedded, the carrier comprising a first wire looped to and fro with a predetermined pitch between lines extending alongside each other and spaced apart by a predetermined distance, and at least one second wire which is looped with substantially the same predetermined pitch, has an amplitude substantially less than the spacing between the two said lines, and is positioned along one of the said lines so as to be in meshing but non-interwoven engagement there with the loops of the first wire, the first and second wires being held in said meshing engagement by the covering material.
2.
A strip according to claim 1, in which there is another, and substantially identical, second wire, this other second wire being positioned along the other said line so as to be in meshing but non-interwoven engagement there with the loops of the first wire, the first wire and this other second wire being held in meshing engagement by the covering material.
3.
A strip according to claim 1, in which the covering material is extruded plastics or rubber material of predetermined shape.
4.
A strip according to claim 1, in which each wire has a square or rectangular cross-section.
5.
A strip according to claim 3, in which the said predetermined shape of the extruded plastics or rubber material is a channel shape and the carrier is of substantially the same shape with the said lines thereof being lines which together define the width of the mouth of its channel shape and in which the extruded plastics or rubber material defines at least one gripping lip which runs along the length of the channel on one inside wall thereof.
6.
A strip according to claim 5, in which the said second wire is configured so that each loop thereof has a first portion in the said meshing engagement and a second portion bent relative to the first portion and embedded within the plastics or rubber material defining the said gripping lip
