Three-Drum Transfer

A method of transferring sheets from one printing unit to another on a sheetfed press (especially that used in offset lithography) in which a set of three transfer cylinders carries the printed sheet from one impression cylinder to the next. The actual sizes of the transfer cylinders vary according to press design, and may be designed to hold one or more sheets at any one time. The transfer cylinders typically possess one of a variety of devices or means to avoid marking or smudging wet ink, and may contain a gripper-bowing device. They may also be air-transport drums. (See also Air-Transport Drum, Chain Transfer, Three-Drum Transfer, and Transfer Cylinder.)
