PURPOSE:To mount a plate on a plate cylinder at a high accuracy without skill by positioning and fixing a pair of pin bases on the gripping spot side in a notch on the circumference of the plate cylinder to support a reference pin in such a manner as to move freely into or out of it. CONSTITUTION:A pair of pin bases 29 are positioned and fixed on the gripping spot in a notch 2 on the circumference of a plate cylinder and a reference pin 36 to be engaged with a reference pin hole 26 on the plate 23 is supported thereon in such a manner as to move freely into or out of it. It allows the three point positioning of a plate 23 on the plate cylinder 1 with such a simple operation as only matching the reference pin hole with the reference pin thereby ensuring a highly accurate mounting for a short time. |
