PUSH RULE LINE MEMBER, RULING MOLD, RULING DEVICE, AND CORRUGATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a push rule line member enabled to form a horizontal rule capable of being precisely folded with respect to a corrugated sheet.;SOLUTION: One end portion of a metallic belt-like plate 11 is formed into a ruling part 12, and this ruling part 12 is formed in a long direction with a plurality of rib shaping recesses 13 having planar V-shaped grooves 14a₁ and 14b₁ formed of one pair of oblique grooves inclined in a reverse direction toward the two side portions, and a straight-shaped projection 15 is formed between the adjoining V-shaped grooves 14a₁ and 14b₁. By pushing the ruling part 12 into the corrugated sheet A, V-shaped ribs 16a₁ and 16b₁ of a V-shaped plan state are formed in a groove bottom surface B of the horizontal rule L, and a linear groove 17 is formed between the adjoining V-shaped ribs 16a₁ and 16b₁.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
