PURPOSE:To prevent alternate production for right and left longitudinal frames from being effected by mistake in the captioned device for a door of a room furnished in foreign style by providing a right longitudinal frame assembling jig and an aligning jig on one of the face and back of a workbench and likewise a jig for a left longitudinal frame on the other, and constructing the workbench freely to be reversed in the face and back thereof. CONSTITUTION:A right longitudinal frame 2 is assembled in a right jig 3 while turning the right jig 3 up, and an aligning jig 7 is projected and fitted in a notch 6 formed in the right longitudinal frame 2. Provided that the longitudinal frame is then mistaken in its right and left, the aligning jig 7 is not fitted in the notch 6 of the right longitudinal frame 2 whereby erroneous work can be prevented. Completed the right longitudinal frame 2, the workbench 1 is reversed by a motor rotated whereby the right longitudinal frame 2 is dropped on a left conveyor 19. Likewise, a left longitudinal frame 4 is assembled by use of left jigs 5, 9. With the arrangement described above, erroneous work can be prevented. |
