DRAWING MACHINE OF SHEET SHAPED MATERIAL TO DRAW THERMOPLASTIC REISN FILM

摘要

PURPOSE: A drawing machine is provided to instantly correct the synchronization of stepless link devices in the ends of a film though a sliding resistance is increased and the connected portion of the stepless link devices are worn. CONSTITUTION: A sensor(10) to detect a specific link is installed in the rear stream of a maximum bending portion in a section to draw a sheet shaped material(1). A controller(11) is installed to control the synchronization of stepless link devices in the ends by a signal from the sensor. Thereby, the synchronization of the stepless link devices are corrected immediately. Therefore, the productivity of a film is maintained and the damage for the stepless link devices is minimized.
