ABSTRACT
A multi-coloured, patterned flooring consists of a web of a first
colour and a differently coloured granulate which is embedded into the
web in an essentially even distribution at least at the surface of the
web. The web and the granulate are made of cross linkable elastomers.
The granulate includes at least two fractions of particles which have
colours different from one another and from the web. The amounts and
colours of the particles in the fractions are selected such that the
mixed colour achievable upon homogeneous mixing of all components of the
flooring essentially corresponds to the first colour. This permits the
complete recycling of edge clippings and production left-overs for the
manufacture of the same flooring without color deviations in the base
material of the web. A process for the manufacture of this type of
flooring is also disclosed.
Couvre-planchers à motifs décoratifs et à couleurs multiples constitué d'une bande d'une première couleur et d'un granulé d'une couleur différente qui est encastré dans la bande dans une distribution essentiellement uniforme, au moins à la surface de la bande. La bande et le granulé sont composés d'élastomères réticulés. Le granulé inclut au moins deux fractions de particules ayant des couleurs différentes l'une de l'autre ainsi que de la bande. Les quantités et les couleurs de ces particules sont choisies de façon que la couleur du mélange homogène de tous les éléments du couvre-plancher corresponde essentiellement à la première couleur. Il est ainsi possible de recycler toutes les rognures et les restants de production afin de fabriquer le même type de couvre-plancher sans qu'il y ait une différence de couleur dans le matériau de base de la bande. L'invention présente également un processus pour la fabrication de ce type de couvre-plancher.
