ABSTRACT:
A belt-type printing machine, having a stationary web-handling assembly, including a pair of impression rolls, and a plurality of belt-supporting assemblies which are mobile and separable from the web-handling assembly, is disclosed. The belt-supporting assemblies each carry a plate support roll and an endless conveyor belt to which a number of printing plates are bonded. The belt-supporting assemblies are each stabilized in a printing position adjacent the web-handling assembly, by locking the plate roll adjacent an impression roll to form between the rolls, a nip through which the web and belt pass. The rolls are locked together in such a way that the rolls of the belt-supporting assembly and web-handling assembly are driven, in unison. A pair of mobile, belt-supporting assemblies are provided for each impression roll of the web-handling assembly, so that one of the belt-supporting assemblies can be removed to a remote location for rebelting while the other is in operation.
