  In recent years, in industrialized houses, so-called prefabricated houses, the thickness of the outer walls has been increased from the viewpoint of improving the strength and texture of outer walls. For example, the plate thickness has been conventionally 12 mm, but recently, the plate thickness has become 33 mm.

  On the other hand, since the structural frame such as a steel frame is the same as the conventional one, it is necessary to cut the joint portion of the outer wall material with the structural frame such as the steel frame.

  Therefore, various processing apparatuses for outer wall materials have been proposed (for example, Patent Document 1).

  However, there is no known processing apparatus capable of processing the outer wall corner material having an L shape.

In addition, the angle formed by both sides of the L-shaped outer wall corner material, that is, the corner angle, is allowed up to a certain angle smaller than a right angle, so that the edge of the outer wall corner material manufactured at the smaller angle is cut with a certain width. Processing is also an issue.
