Treadmill belt with layer of thermoplastic foamed material

An endless treadmill belt comprising:

• an endless layered composite, including:
• a) a first foamed layer (11, 12, 13, 14, 15, 16, 17, 18) of a thermoplastic foam and having a top side (25, 26) and a bottom side (34, 35, 36);
• and
• b) a first traction layer (41, 42, 43, 44, 46, 47, 48) comprising a woven fabric and having a traction layer bottom side (54, 56, 58) which forms a surface able to come into contact with rollers or a deck of an exercise treadmill;
• wherein the first traction layer (41, 42, 43, 44, 46, 47, 48) is adhered to the bottom side (34, 36) by a crosslinked adhesive (61, 62, 63, 64, 66);
• whereby the layered composite is made endless by only making the first foamed layer (11, 12, 13, 14, 15, 16, 17, 18) endless by direct welding using the material of the first foamed layer as a hot-melt adhesive, and without using any other adhesive.
