Title: METHOD, APPARATUS AND SYSTEM FOR PRODUCING A POLYURETHANE SPORTS FLOORING
Abstract:
Method for producing a polyurethane flooring for a sports ground, wherein a polyurethane foam (128) is applied to a ground in at least two lanes arranged adjacent to each other, comprising the following steps: providing polyurethane reactive components comprising a isocyanate component and a polyol component, determining environmental data, determining process parameters for mixing the polyurethane reactive components, wherein the process parameters depend on the environmental data, mixing the foam (128) by mixing the polyurethane reactive components using a froth foam process with the process parameters, applying a first lane of the liquid foam (128), applying a second lane of the liquid foam (128), wherein a side edge of the second lane gets in contact with a side edge of the first lane, wherein the process parameter are determined so that the foam (128) of the first lane is not cured before applying the foam (128) of the second lane.
