Abstract:
1. A folding blade cylinder comprising: a rotatable cylinder body having a cylinder body periphery; five groups of tools distributed evenly on said cylinder body periphery, each of said five groups of tools being supported for working movement with respect to said cylinder body periphery; a separate control arm connected to each of said five groups of tools and usable to effect said working movement of each of said five groups of tools; a stationary cam disk associated with said cylinder body, said stationary cam disk being operable to control said working movement of each of said five groups of tools, said stationary cam disk being traced by each said separate control arm of each of said five groups of tools; a rotatable cover disk including multiple covering cams, said rotatable cover disk being selectively rotatable in relation to said rotatable cylinder body, each of said covering cams being selectively movable between an inactive position, in which it prevents said control of said working movement by said stationary cam disk, and an active position in which it permits said control of said working movement by said stationary cam disk; a first group of said plurality of covering cams and having four of said covering cams each positioned at an angular spacing from an adjacent one of said first group of covering cams of one of 60° and 120°; and a second group of said plurality of covering cams and having three of said covering cams each positioned at an angular spacing from an adjacent one of said second group of covering cams of one of 90° and 180°, each of said second group of covering cams being positioned between two adjacent ones of said first group of covering cams, said first group of covering cams and said second group of covering cams cooperating to adapt said folding blade cylinder for one of non-collect, single-collect, double-collect and triple-collect operation.
