Abstract
The present invention provides a gauging jig, for gauging whether projections of first and second rollers, which are disposed in parallel on both sides of a carrying surface of a platform, coincide on the surface. The gauging jig includes a pointer instrument which is provided on a side of the platform and perpendicular to the carrying surface. The pointer instrument has a first end and a second end. The first end is connected to the first roller and intersects with a central axis of the first roller, while the second end extends close to the second roller. With the gauging jig, an operator can promptly and accurately gauge whether the projections of the first and second rollers coincide on the carrying surface. Therefore, gauging time can be saved while times of trial production can be reduced or even omitted, thereby improving the production efficiency and reducing cost.
