https://www.contitech.de/mediaservice/suche.aspx is a good place to start finding out.
This is a very good question. I think the carcass tension on exit from the press would be very low and the tension on the entry side would be that imparted to the workpiece as it is drawn through the plattens without slip. If the tension is too high the belt would distort on cooling and if too low the rubber would do some start up work all on it's own.
Belt manufacture is fascinating, some people need carcass elements just to induce preload during cooling, which in turn helps to maintain a particular profile. You have to talk to the experts: they're always helpful. ■
Pulling force while Belt manufacturing
During fabric belt manufacturing, what is the pulling force (to keep the plies taut ) given by the manufacturers between front and back of the vulcanising press, so that belt elongation will be under control when the belt is put into service?
Is there any DIN standard for the above value in relation with the belt rating? ■
