Correct initial elongation for conveyor and drive belts

Situation 1: Correct installation of a Habasit conveyor belt: The tension of a conveyor belt is determined by feel It is important to make sure that the driving pulley can drive the belt without slipping even under a maximum load The minimum and maximum admissible initial elongationElongation of Conveyor Belt We use NN (nylon x nylon) belts at our sandwich belt highangle conveyors This is precisely because of the low elastic modulus which facilitates the tighter convex curves of the troughed belts The elastic stretch is desirable, the permanent stretch is not but is worth itElongation of Conveyor Belt bulkonline Forumselongation at fitting ε of the belt, resulting from the belt load To establish ε, see pages 7 and 8 2 The production tolerances (Tol) of the belt as regards the length 3 any external influences that might necessitate greater elongation (tensioning) than usual, or might require a safety margin, such as for example the impact of temperature,CaLCULaTIOn METHODS – COnvEYOR bELTS
