Abstract: An apparatus including a raceway comprising a flexible surface, and a mechanism located under the flexible surface that forms waves of motion in the flexible surface. The waves can be random or controlled, with varying heights. This application provides several embodiments of the mechanisms of the invention. The disclosed apparatus can be utilized for recreational, sports or industrial purposes and for other applications.

Abstract: “UNDULATING TRACK AND MECHANISMS FOR FORMATION OF THE WAVES ON THIS TRACK”, describes apparatus that can be used with recreational purposes, sports, industrial, among other applications, comprising a rolling track or raceway (1), consisting of flexible material mounted on a compatible structure, also flexible, track-type tubes (2) being supported by the ends of the conveyor pipe (2) in lateral supports (3) of the beam type or the wall or similar structure; and to contain a cart (4) with wheels (41) supported on rails (5) mounted underneath the bearing race (1) and having a wave forming mechanism, random or controlled, mounted on said cart (4) moving said wave-forming mechanism along the bearing track (1) by means of a traction mechanism of the type carried by chains or steel cables.
