A treadmill (10) having a belt (12) and deck (14) with a relatively long, usefullifetime is disclosed. The belt of this assembly has a tread layer (54) formed of PVC plastic or other material that serves as the layer of the belt upon which a person actually steps, and a fabric layer (62). The fabric layer has weft threads (64) that extend laterally across the belt and that are substantially embedded in the plastic material and warp threads (66) that extend longitudinally along the belt that have exposed sections that extend outside of the plastic material. The fabric layer is woven so that the exposed sections of the warp threads are equal to at least 50% of their overall length. The deck of this treadmill is formed with a plywood substrate (70) and a wax-embedded hardboard (72). The substrate provides structural support for thehardboard and the persons using this treadmill. The hardboard serves as the surface along which the belt rides when a person steps on the treadmill.
L'objet de la présente invention est un tapis roulant (10) avec bande (12) et plateau (14), ayant une durée utile relativement longue. La bande de cet ensemble présente une couche (54) en PVC ou en un autre matériau qui sert de couche de traction circulable sur laquelle la personne marche, et une couche de tissu (62). La couche de tissu comporte des trames (64) qui se prolongent latéralement en travers de la bande et qui sont sensiblement noyés dans le matériau de plastique, ainsi que des fils de chaîne (66) qui se prolongent longitudinalement sur la bande et qui ont des sections apparentes qui se prolongent à l'extérieur du matériau de plastique. La couche de tissu est tissée de manière que les sections apparentes des fils de chaîne sont égales à au moins 50 % de leur longueur globale. La plate-forme de ca tapis roulant est formée d'un subjectile en contreplaqué (70) et d'un panneau dur enduit de cire (72). Le subjectile assure le support structurel du carton et des personnes utilisant le tapis roulant. Le panneau dur sert de surface sur laquelle circule le tapis roulant lorsqu'une personne marche dessus.
