<p>In a method and assembly for covering a substrate, an insert and, in operation, the substrate are positioned in the direction of recovery of a heat-recoverable member. The insert comprises a material that is fusible or a material that becomes less viscous on heating, and may be corrugated or may include at least one protuberance, which may comprise a material that can become flowable or an infusible material. Corrugations or protuberances are such that they can be detected through the heat-recoverable member before application of an amount of heat which is sufficient to cause the said material to flow, but can indicate, for example by fusing so that they are no longer detectable, when sufficient heat has been applied to cause the said material, and/or the corrugations or protuberances, to flow.</p> |
