The covering material, designed to be resistant to slashing, consists of a layer of a supple material backed by a reinforcement made from strips (1) or filaments which are set at intervals and made from a material which resists the passage of a cutting implement. The strips or filaments are wavy in shape, either in curved lines or having straight segments (2, 3) which are regularly repeated along their length. The reinforcing strips or filaments are situated so that a cutting implement inserted in the material will inevitably encounter one of them in whichever direction it is moved. They are independent of one another and attached to the supple material layer by one or more layers of adhesive or plastics in which they are at least partially embedded. The strips can be made, for example, from plain or reinforcing plastic or a composition material reinforced with glass or carbon fibres, e.g. Kevlar (RTM). |
