The invention relates to a reinforcement layer for elastomeric products, in particular for the belt bandage (8), having cords as reinforcement, where the cords have at least two yarns, where a first yarn of the yarns is made of polyamide and where the ends of all yarns of a cord are twisted together. The problem addressed by the invention is that of providing a reinforcement layer for elastomeric products which exhibits a relatively high tensile force value for an elongation of 4% or more and which exhibits relatively low shrinkage based on linear density of the reinforcement. This is achieved in that the cords are hybrid cords having precisely three yarns, in that the hybrid cord has the first yarn and a second yarn made of HMLS-PET, in that the hybrid cord has a first yarn or a second yarn as third yarn, and in that the linear density of each hybrid cord is at least 5000 dtex.
