Abstract

The machine has a pair of drive rollers coupled with a tensioning device. The tensioning device consists of an arm (24) pivoted at the centre (23) and spring loaded at one end. The arm carries two rollers (20, 21) and the position of the arm varies the distance between these rollers. The tension is regulated by mechanical or electrical control stations along the path of the film from the roll (3) to the exit rollers.
