REVERSING DEVICE OF SHEET-FED PRESS AND SHEET-FED PRESS

摘要

Disclosed is a reversing device of a sheet-fed press (1) which comprises a reversing double cylinder intermediate cylinder (37) and a reversing cylinder (38) and is capable of reversing the front and back of a sheet (S) by tearing the sheet (S) off from the reversing double cylinder intermediate cylinder (37) by turning the rear end of the sheet (S) which is held on the outer circumference of the reversing double cylinder intermediate cylinder (37) while holding the rear end of the sheet (S) by means of the reversing cylinder (38), and then conveying the sheet (S) thus torn off along the air conveyance route (K) of the sheet (S) formed between the reversing double cylinder intermediate cylinder (37) and the reversing cylinder (38), wherein a vacuum wheel (39) which can suck the sheet (S) is provided arranged in a manner as to touch the margin of the sheet (S) flying along the air conveyance route (K), and a margin extending in the conveyance direction of the sheet (S) is formed in the printed sheet (S) which is conveyed by means of the reversing double cylinder intermediate cylinder (37).
