摘要:PROBLEM TO BE SOLVED: To clear the scales on the surface of a measuring tape for easy reading by avoiding reflection on the surface. SOLUTION: Either side of a polyester or polyamide thin film is ground with sand rolls of different grain sizes in succession to have a frosted side that had been a glossy one. When glued to the surface of a measuring tape where its scales are printed, the polyester or polyamide thin film with the fronted side makes on the measuring tape a nonreflexive surface of a sort, which by contraries makes the scales easier to read.
