Abstract: The steel type band moves in front of the rectangular, block-shaped printing platen over which passes the paper web to be printed. The band has a track of individual type symbols below which are located the timing tracks. The impact surfaces on the platen has on its front and rear sides, layes made of bearing material esp. lead bronze against which the printing hammers impact the printing type on the type band. The use of such a platen markedly increases the service lift of the type band and improves print quality by offering uniform frictional characteristics.
