CONICITY MARKING DEVICE

摘要

PURPOSE: A conicity marking device is provided to make the length of marking tape wound around a tape winding roll regular so that the markings stamped on a tire is formed by fixed distance. CONSTITUTION: A tension roll(39) is closely installed to a driving roll(38) of a marking part(30). The tension roll is movable leftward/rightward by a variable axis(39a) supporting the tension roll. A tension spring(39b) is installed to the variable axis so that the tension roll is always pressed on the driving roll. The rotation frequency of the driving roll is limited by the tension roll to adjust the amount of marking tape(34) wound around a tape winding roll(33) to be fixed.
