Problems solved by technology

However, in conventional equipment the membrane can also be prevented from slack, but there will be a certain loss in the membrane due to the torsional force acting on the membrane, which will elongate the membrane
As a result, productivity drops

Abstract

The present invention relates to the device for preventing film damage in certain degree during making continuous holographic film. During making wide holographic film, tension regulating roller is set between the original film roller and the guide roller. The sensor senses the pressure on the tension regulating roller, so that the rotation speed of the winding roller is regulated. The film producing the pressure is guide with the tension regulating roller between the guide and the winding roller. Regulating the rotation speed based on the pressure on the tension regulating roller can avoid the damage of the film in certain degree.

Description

technical field [0001] The present invention relates to a device for preventing film damage to a certain extent during continuous production of holographic films, in particular to a device for preventing film damage to a certain extent by adjusting the rotating speed of rolls, wherein the film damage is when the film is damaged to a certain extent Caused by stopping the winding roll when the maximum suction force is applied by the tension roll, where, when making a wider holographic film continuously, a tension roll is provided between the raw film roll and the guide roll, and a suction force suitable for sensing the film is provided Level sensor, where the film is guided by a tension roller arranged between a guide roller and a take-up roller. Background technique [0002] When making a wider holographic film, since all the rolls in the equipment are longitudinally composed, the original film passes through the guide roll, the hologram disc roll, and the pressure roll in se...
