Abstract
A sheet guide unit for a sheet-fed press which will prevent the sheet from flapping or fluttering, and allow sheets of thinner paper to be conveyed smoothly even when using a skeleton cylinder, The sheet guide unit is provided under an intermediate cylinder or a delivery cylinder, and has a curved sheet guide surface with which the lower surface of the cylinder creates a small sheet guide space, the space through which an air stream is directed. An air supply chamber and a pair of air aspiration chambers are provided for directing air through the sheet guide space. An air guide fin which is an outer extended portion of the curved sheet guide surface directs the air from the sheet guide into the aspiration chambers.
