Abstract

PURPOSE:To form the groove with a good appearance in a simple manner by a method wherein the groove is formed on the foamed polystyrene sheet by biting both edges of the with of the groove width two sheets of thin biting edges having cutting edges of an acute angle while skiving the whole width of the groove with a skiving edge. CONSTITUTION:Knotches c, c' at both edges of the groove width b are bitten by two sheets of the biting edges 10, 10' having cutting edges of an acute angle, thereafter, the whole said width of the groove is skived by the skiving edge 11 opposing to the bitting edges 10, 10' under removing a skived chip a continuously by reeling it into a spiral roll at a retrieving section, thereby forming the groove d on the sheet. Accroding to this method, the groove d such as of U-shape or the like is formed on the foamed polystyrene sheet A. The sheet A formed with this groove d is used as the peripheral side board for forming the vessel such as the folding box or the like which has the groove d for inserting the bottom board D for the box. From a view point to promote the natural drop of the skived chip a, it is preferable to attach each cutting edge so as to keep an upward direction.
