GAP COVER FOR BLANKET CYLINDERS IN SHEET-FED OFFSET ROTARY PRESSES

摘要

A blanket cylinder is covered by a blanket having ends secured by spindles in a wide gap extending parallel to the central axis of the cylinder. The cylinder includes a cover rail having a substantially mushroom-shaped cross-section disposed along the length of the gap. The cover rail is attached to the base of the gap so that the cover rail bears against the blanket secured on the spindles and sealing material is provided between the end walls of the cylinder and the adjacent surfaces of the cover rail.
