#CMT# #/CMT# The device has a pressing device (28) includes a partial-width coil with an effective running surface. The pressing device presses webs (2, 12, 13) i.e. papers, printed with images (3) of printing image width (bs) in a printing unit (1) of a printing machine. The coil is in cooperation with rollers (26, 56, 57, 59) and arranged downstream to the printing unit in a web path such that the printed webs are guided between the rollers and the coil and pressed at the rollers in an engaging position of the coil. A cleaning device cleans the running surface of the coil. #CMT# : #/CMT# An independent claim is also included for a printing machine. #CMT#USE : #/CMT# Printing machine device e.g. web rotary press device and newspaper printing press, for printing images on webs i.e. papers, of a printing product i.e. card e.g. post card, flyer, card with odor, envelope or voucher card. #CMT#ADVANTAGE : #/CMT# The utilization of the pressing device achieves high quality requirements of a printing product i.e. card. The utilization of the cleaning device secures the card in printed areas with corresponding counter pressure without impairing quality of the card. The design of the printing machine device precisely increases maintenance intervals up to exchange of cleaning elements, and decreases color contaminations of a decelerated coil in a short washing period. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a web rotary press. bs : Printing image width 1 : Printing unit 2, 12, 13 : Webs 3 : Images 26, 56, 57, 59 : Rollers 28 : Pressing device. |
