ABSTRACT:
Sandwich-structured double layer floor covering with the upper surface layer of fleece made of synthetic polymer fiber of at least 5 mm thickness having, on the upper surface, needle work of with a minimum of 2 million stitches per square meter, and with a lower layer of cellular polyethylene having a maximum density of 35 kilograms per cubic meter and a thickness of at least 5 millimeters. The combination of the two different layers and needling make it particularly suitable as a floor covering for sports-grounds especially with regard to sliding friction on the top surface and the shock-absorption property of the lower layer.
