DEVICE FOR TRANSMISSION OF SEPARATE SHEETS TO PRINTING CYLINDER OF SHEET ROTARY PRINTING MACHINE Russian patent published in 1999 - IPC

Abstract RU 2129490 C1

FIELD: printing equipment. SUBSTANCE: device has cylinder 2 for transmission of sheets by means of mobile setting plate 3, which is equipped with sheet clamps 4 and side ends which may be separately altered for each rotation of transmission cylinder 2 by means of roller lever 9 towards circle, so that sheet to be transmitted to printing cylinder is positioned according to precise printing drive. Goal of invention is achieved by design of roller lever which is mounted on transmission cylinder 2 for movement and is driven towards axle 1 of cylinder by runner of actuating member 15, 19 which is hanged with possibility of deviation above axle 1 of cylinder. Said actuating member is equipped with separately controlled rests 19a, 19d, which deflect corresponding actuating member 15, 19 for preset size due to interaction with rotating cams 24a-24d for each turn of transmission cylinder 2. This results in movement of corresponding end of setting plate 3. EFFECT: increased precision of automatic setting of sheet position. 6 cl, 5 dwg
