Abstract

PURPOSE:To efficiently provide the ALC panel having an L-shaped section without requiring skill by removing a part of a rectangular parallelepiped while cutting this part and while relatively moving the ALC block of the rectangular parallelepiped and a rotary cutting blade. CONSTITUTION:This invention relates to the process for production of the corner panel of lightweight foam concrete, i.e., ALC, formed by aging in an autoclave and the process for production of this panel. The conventional cutting system consists in setting the ALC block 1 on a truck 2, as shown in Fig., horizontally cutting B the block by a horizontal cutting blade 3, then vertically cutting C the block by a vertical cutting blade 4 and carrying out an operation E to take an end material 5 out of the corner worked part of the resulted D by a manual operation. This invention consists in obtaining the panel having the L-shaped section on the corner worked surface (b) by rotation of the cutting blade 6 set in a prescribed position in an arrow direction while transporting the ALC block (a) in a flow direction of an arrow by means of a roller conveyor. As a result, the need for an operation to remove unnecessary parts and an operation to pulverize these parts is eliminated and the non-efficiency of the batch operation and the waving of the cut surface are prevented.
