<p><P>PROBLEM TO BE SOLVED: To efficiently form even an elongated ruled line, and to prevent the break of a resin corrugated cardboard at the periphery of a ruled line by equalizing the movement amount and the revolution amount of a heating roller with respect to the resin corrugated cardboard to avoid the occurrence of revolution resistance when the heating roller is used to form the ruled line. <P>SOLUTION: In the ruled line forming device for forming a ruled line to become a crease by moving a ruled line roller in the two dimensional direction while pressing the ruled line roller to the resin corrugated cardboard placed on a table, the ruled line roller is drive-connected to an electric motor rotating at rotation speed synchronized with moving speed of the ruled line roller with respect to the resin corrugated card board. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
