Optical reflection plate and method of producing the same
First Claim
1. A method for manufacturing a light reflector plate characterized in that narrow cuts are intermittently formed in a light-reflecting plastic foam film or sheet along a straight line in such a manner as to penetrate from one side surface of the film or sheet to the opposite side surface thereof, and subsequently the film or sheet is bent along the cuts to thereby obtain a bent reflector plate.

Abstract
An object of the present invention is to provide a light reflector plate having the following advantages A to D: A. no need for high initial investment for dies or the like required for forming a three-dimensional shape; B. simple working and low cost of working; C. accurate shape retention of a reflector plate after bending work, and excellent dimensional stability even under severe conditions of use; and D. simple and low-cost attaching work for shape retention. To achieve the above object, according to the present invention, narrow cuts 4 are intermittently formed in a light-reflecting plastic foam film or sheet 2 along straight lines in such a manner as to penetrate from one side surface of the film or sheet 2 to the opposite side surface thereof. Subsequently the film or sheet is bent along the cuts.
