摘要

#CMT# #/CMT# The folding unit (1) has support cylinders (30.1-30.5) and cutting cylinders (20.1-20.3), of which one pair of cutting cylinders are cooperated with folding devices and retaining units to form respective folds of train by transverse cutting of strand sections. The first and second pairs of cylinders are provided with respective folding devices and cutting units for cross-cutting a web strand to separate strand portions. The support cylinders (20.1,20.2) are located in a common strand running space (LS) with respect to cutting cylinders for processing web strand (BS). #CMT#USE : #/CMT# Folding unit for web-fed rotary printing machine such as newspaper printing machine or commercial printing machine. #CMT#ADVANTAGE : #/CMT# The folding unit can be accommodated in less space. The folding unit can be set up easily. The cost-effective and compact versatile folding can be created with string sections or print products can be selectively folded. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of folding mechanism. 1 : Folding unit 20.1-20.3 : Cutting cylinders 30.1-30.5 : Support cylinders BS : Web strand LS : Running space.
