    Elastic elongations of a belt loaded with a longitudinal force cause a reduction of forces in the zone where the belt comes off the drive pulley . This necessitates causing much greater forces of preliminary belt tensioning. Permanent deformations of the belt are periodically compensated by moving the tensioning pulley during conveyor stoppages.
