ABSTRACT:
A power transmission belt having the form of a Mobius strip with a single half twist consisting of a laminated structure assembled from a single strip of flexible material. The flexible material may be an adhesive tape or similar material having an adhesive surface on one side thereof, and a friction surface on the other side thereof. The laminated structure is assembled by first, forming an open loop with a first end portion of the flexible strip of material, and secondly, twisting said end portion 180.degree. about its longitudinal axis so as to place the adhesive surface of the twisted end in intimate face-to-face contact with the adhesive surface of a remaining portion of the flexible material, and thirdly, pressing together the adhesive surfaces of the remaining portion of the strip of material and the closed preformed loop in a manner whereby a laminated structure is formed from several congruent layers of said flexible material.
