ABSTRACT:
A vehicle or a conveyer has a pair of rolls which are spaced from each other and provided with central axes of rotation situated in a given common plane. An endless belt extends between and is guided around these rolls with this belt having on opposite sides of the above plane a pair of runs which respectively travel in opposite directions during rotation of the pair of rolls. This endless belt has a pair of opposed endless side edge regions and midway between the latter an elongated endless central region which is flexible but substantially non-stretchable. Between the central region and each of its side edge regions the endless belt has a lateral endless elastic portion which is capable of stretching and contracting longitudinally.
