SHEET MATERIAL MEANDERING CORRECTING DEVICE AND MEANDERING CORRECTING METHOD

摘要

PROBLEM TO BE SOLVED: To correct meandering rapidly in a vacuum atmosphere so as to convey traveling sheet material stably by providing a sheet material winding-out part, an edge part detector, a sheet material winding-out mechanism and winding-out part guide mechanism in a vacuum chamber. ;SOLUTION: While confirming the present position of an edge part detector 1 by an edge part detector present position detecting means and a present position display means 13, a push button 14 of an arithmetic part 12 is pressed to move the edge part detector 1 into a reference position corresponding to the width of sheet material. When the sheet material travels by the operation of a vacuum evaporation device and meandering is generated, the edge part detector 1 detects a film edge part, arithmetic processing is performed by the arithmetic part 12 installed in an atmospheric pressure atmosphere, and the result is transmitted to a winding-out moving means 10. Winding part guide mechanism 7 is operated to move a winding-out part 5 in a sheet material width direction, and the meandering quantity is corrected so that the edge part of the sheet material is always in a specified reference position.;COPYRIGHT: (C)1997,JPO
