PURPOSE:To increase the accuracy of scales, by coinciding the front surface of a tape measure with the back surface for scale, through the same scale on both end sides of one side of a tape, folding of the tape by the scale on front side into two, and coating of a transparent resin on the outside. CONSTITUTION:Both end sides of one side of a resin-made tape 1 molded with extrusion are applied for the same scales 2. The scales 2 are printed by gravure or by sticking a scale tape on the tape. An adhesive is applied to the tape 1, and the tape 1 is folded into two at almost the center line in lengthwise direction by taking the scales 2 as upside. A transparent resin layer 3 is coated by extrusion on the external surface of the folded tape 1. With such a manufacture, the scales on the front and back are coincident with highly accurate scales. |
