NOISE REDUCTION DEVICE FOR FILM WINDING SWITCHING MACHINE

摘要

PROBLEM TO BE SOLVED: To see through the inside of a machine and attain safety, noise prevention and easy maintenance. SOLUTION: This home warp film winding switching machine A involves a transparent sound absorbing member 2 of triple structure which is formed by sandwiching a transparent film material between a small-hole-diameter expansion metal and a large-hole-diameter expansion metal and which is affixed onto at least the internal surface of the opening of a see-through window in a box-shaped safety cover 1 surrounding the periphery of the winding machine. It is thus possible to see through the inside of the cover and reduce leakage, to the outside, of noise generated from the winding switching machine.
