Abstract

There are disclosed a strip capable of serving as a waist seal or glass run channel of a motor vehicle, the strip having a substrate (1), a flock (3) of a different colour from the substrate, and an adhesive (2) securing the flock to the substrate, the adhesive being of a colour similar or identical to that of the flock; as well as a strip capable of serving as a waist seal or glass run channel of a motor vehicle, the strip comprising a substrate (1) having a colour other than black, flock (3) of a colour similar or identical to that of the substrate, and an adhesive (2) for applying the flock to the substrate, the adhesive being clear or of a colour similar or identical to that of the substrate. The strips should, when fitted to a vehicle, present a generally uniform colour. <IMAGE>

Description

SPECIFICATION Strips with coloured flock This invention relates to strips with coloured flock and is more particularly, but not exclusively, concerned with sealing strips with coloured flock.

It is known to provide motor vehicles with sealing strips either for the purpose of draught exclusion or forthe purpose of guiding sheets of glazing material.

Guiding strips are often provided on certain oftheir surface regions with flock in order to assist in the smooth movement of the sheet of glazing material.

Hitherto, flock has usually been applied to the substrate by means of an adhesive and, in the past, the substrate and the flock have been black, with the adhesive being clear or also black.

Strips used on motor vehicles are normally produced by extrusion and such strips traditionally have a black appearance.

In the production ofmotorvehiclesthere is nowadays a greater consideration given to aesthetic considerations and it is felt that it would be attractive to provide strips having a flock which is coloured differentlyfromthesubstrate of the strip, for instance a blue or grey flock, when the substrate is black.

According to one aspect of the present invention, there is provided a strip having a substrate, a flock of a differentcolourfrom the substrate, and an adhesive securing the flock to the substrate, the adhesive being of a colour similar or identical to that of the flock.

The intention of thins one aspect of the present invention is that, even if there are small areas where the density offlockfibres is less than sufficientto coverfully the substrate, the adhesive will nonetheless provide a colour generally similarto thatoftheflock.

The substrate is likely to be black, but need not be so.

The substrate could, for instance, be formed of the material traditionally employed in the production of sealing strips and glass run channelsformotor vehicles, for instance styrene butadiene rubbers and ethylene/propylene, dienemonomer rubbers.

The adhesive can be of the type traditionally employed but with the incorporation of a suitable colouring agent, itselfwell known.

Coloured flocks are known, such as in the production of wall papers, and the flockto be employed as a component of the present invention can be readily obtained from normal market sources.

The techniques applied in the production of strips according to the different aspects of the present invention can be conventional, in that, after extrusion of the substrate, adhesive is accurately applied to those regions of the substrate to which the flock is to be adhered and, thereafter, the flock is applied to the substrate and the adheres to the regions provided with the adhesive.

Although waist seals and glass run channels are types of strip normally provided with flock, nonetheless the invention can, if desired, be applied to other types of strips found on motor vehicles or in other applications.

Nowadays, certain components of motor vehicles are formed, at least in their surface regions, with a colour which matches other parts of the vehicle; for instance, the bumpers offenders of motor vehicles sometimes match the colour of the bodywork panels of the vehicle.

In the case in which the substrate of a strip is a colour other than black, then, when flock is to be applied to it, the flock could be an identical orsimilar colourto the substrate and the adhesive could be eitherthe same or similar colour asthe substrate or could be clear.

Thus, according to a second aspect of the present invention,there is provided a strip comprising a substrate having a colour otherthan black, flock of a colour similar or identical to that of the substrate, and an adhesive for applying the flock to the substrate, the adhesive being clear or of a colour similar or identical to that of the substrate.

For a better understanding of the present invention and to show howthe same may be carried into effect, reference will now be made, by way of example, to the sole figure which is a cross-section through one embodiment of a strip in accordance with the present invention.

In the drawing, a glass run channel, generally indicated bythe reference numeral 1, is provided on certain regions (shown on a grossly magnified scale) with an adhesive layer 2which secures a flock3to those regions. By way of illustration, the substrate 1 can be black and the adhesive 2 and flock 3 can be blueorsomeothercolourotherthan black. Asthe concept of the present invention can be applied to numerous applications, it will be appreciated thatthe cross-section of the substrate could vary enormously from one caseto another, as could also the magnitude of the area to which the adhesive and flock are applied.

There is a tendency these days for certain motor vehicles to be produced with an overall white appearance so that the body, bumpers orfenders, and wheels are all formed white. In such a case the strips employed in the car could aiso be formed of a white material and, where those strips incorporate flock,forexampie in the region where there are movable sheets of glazing material, the flock could be white and the adhesive could be clear or white, applied to a white substrate. Instead of the motor vehicle having an overall white appearance, the vehicle could have an overall appearance in another colour. White, for present purposes, is regarded as a colour.

1. A strip having a substrate, a flock of a different colour from the substrate, and an adhesive securing the flockto the substrate, the adhesive being of a colour similar or identical to that af the flock.

2. Astripaccording to Claim 1, wherein the substrate is black.
