PURPOSE:To facilitate selection of templates by a feeler and improve accuracy in profile processing, by attaching the feeler in an eccentric way to a holding device thereof which can be rotatably positioned with an angle of 180 deg., so that the feeler can selectively oppose respective templates which are disposed in parallel. CONSTITUTION:An edge line 26 of a feeler 23 is disposed to oppose the side face of a template T1, and the feeler is slidably moved to make the copying motion when hydraulically advanced by a copying ram 1. When the profile of another template T2 is desired, the ram 1 is retreated, a fixing handle 18 loosened, and a slidable washer 17 shifted to provide a space for a fixing shaft to be axially moved. Then a feeler holding device 21 is pushed toward the side of the template together with a positioning device 15, whereby an angle 14 provided on the positioning device 15 is disengaged from a trapezoidal groove 7 provided on a support 3. If then the positioning device 15 is rotated 180 deg., the feeler 23 comes to face the side face of the template T2 by virtue of an eccentricity e. Then the handle 18 is refastened to complete the positioning. Thus, facility in selection of the templates by the feeler, high rigidity in the positioning, and accuracy in profile processing can be provided. |
