<p>A moving belt which is tubularized and detubularized or otherwise shaped as by moving it through right angle turns is relieved of induced stresses and strains by passing the belt over a belt contouring device such as a set of coaxial pulleys of varying diameters with a preselected profile such that it distorts the belt in a manner which compensates for the distortion of the previous tubularization or the like.</p> |
