BENDING RULED-LINE WORKING METHOD AND THERMOPLASTIC RESIN SHEET HAVING BENDING RULED-LINE

摘要

PURPOSE: To provide a method for working bending ruled-lines with which a sheet having bendable property can be obtained easily, and a thermoplastic resin sheet having bending ruled lines which can be obtained by the above- mentioned method. ;CONSTITUTION: A device to be used comprises a cradle 11, a latticed gauze 12, and a ruling blade 13. The gauze 12 is formed of wire rods 14 braided laterally and longitudinally. The ruling blade 13 is arranged directly above one longitudinal or lateral wire rod 14 in the direction along this wire rod 14. By using this device, a thermoplastic resin sheet 15 is placed on the gauze 12, the ruling blade 13 is lowered so as to press the resin sheet 15. Thus, on one face of the resin sheet 15, a first bending ruled-line on which the ruling blade 13 is transferred is formed. On the other face of the resin sheet 15, a second bending rule-line on which the wire rod 14 is transferred is formed.;COPYRIGHT: (C)1996,JPO
