Abstract
Abstract A sealing, trimming or finishing strip has a metal carrier advantageously made up of U-shaped side-by-side metal elements interconnected by integral connecting links. The carrier is completely embedded in flexible material, such as rubber or plastics material, which defines inner gripping and sealing lips. A sealing portion is also provided. Substantially all of the material on the inside of the carrier (including the material of the lips) is sufficiently transparent or translucent to enable the carrier, or at least the connecting links thereof, to be visible through it. This facilitates cutting of the strip into lengths, because it enables the cutter to be located so as to cut through the connecting links of the carrier, rather than through the U-shaped elements thereof. The channel-shaped material externally of the carrier is visually opaque.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
A channel-shaped strip, comprising a reinforcing channel-shaped carrier, and channel-shaped flexible material in which the carrier is embedded, substantially all of the flexible material on the inside of the carrier being such that the carrier is visually apparent through it and substantially all of the channel-shaped flexible material on the outside of the carrier visually concealing the carrier.
Claim 2
Dependent Claim
58 words
A channel-shaped strip, comprising a reinforcing channel-shaped carrier, and channel-shaped flexible material in which the carrier is embedded, substantially all of the flexible material on the inside of the carrier being such that the carrier is visually apparent through it and substantially all of the channel-shaped flexible material on the outside of the carrier visually concealing the carrier.
Claim 3
Dependent Claim
36 words
A strip according to claim 1, in which the flexible material integrally defines at least one lip which runs longitudinally along the channel, the lip projecting inwardly of the channel from an inside side wall thereof.
Claim 4
Dependent Claim
35 words
A strip according to claim 1, in which substantially all of the flexible material on the inside of the carrier is of softer consistency than the channel-shaped flexible material on the outside of the carrier.
Claim 5
Dependent Claim
23 words
A strip according to claim 1, including a sealing portion attached to one of its outside walls and running longitudinally along the strip.
Claim 6
Dependent Claim
17 words
A strip according to claim 4, in which the sealing portion is integral with the flexible material.
Claim 7
Dependent Claim
18 words
A strip according to claim 4, in which the sealing portion is adhesively attached to the flexible material.
Claim 8
Dependent Claim
90 words
A channel-shaped strip, comprising a reinforcing material carrier made up of a plurality of side-by-side U-shaped elements which are interconnected to each other by means of integral connecting links, substantially channel-shaped flexible material completely embedding the carrier and defining integral lips running along opposite inside walls of the channel, substantially all of the flexible material on the inside of the carrier being sufficiently translucent that the connecting links are visible through it and being of softer consistency than the remainder of the channel-shaped flexible material, the said remainder being opaque.
Claim 9
Dependent Claim
90 words
A channel-shaped strip, comprising a reinforcing material carrier made up of a plurality of side-by-side U-shaped elements which are interconnected to each other by means of integral connecting links, substantially channel-shaped flexible material completely embedding the carrier and defining integral lips running along opposite inside walls of the channel, substantially all of the flexible material on the inside of the carrier being sufficiently translucent that the connecting links are visible through it and being of softer consistency than the remainder of the channel-shaped flexible material, the said remainder being opaque.
Claim 10
Dependent Claim
18 words
A strip according to claim 7, having a sealing portion running longitudinally along one of its outside walls.
