Abstract:
A device for rerouting signatures comprising:a first conveyor belt system having first conveyor belts, and a second conveyor belt system having second conveyor belts, said first and second conveyor belts cooperating to clamp signatures and to move the clamped signatures in a signature conveying direction along a signature infeed track;a first signature conveying track and a second signature conveying track;a stationary guide wedge system extending transversely to said conveying direction of travel of said first and second conveyor belts, said stationary guide wedge system having an upper guide surface, a lower guide surface, a thin, leading edge and a thick trailing edge, said first conveyor belts and said second conveyor belts diverging at said thin leading edge, said first conveyor belts extending along said first signature conveying track and said second conveyor belts extending along said second signature conveying track;upper grooves on said upper guide surface adjacent said leading edge, and lower grooves on said lower guides surface adjacent said leading edge;an upper plane defined by said upper guide surface, and a lower plane defined by said lower guide surface, said upper and lower planes defining a wedge-shaped space surrounding said stationary guide web;a first cam row and a second cam row, said first cam row engaging said first conveyor belts and said second cam row engaging said second conveyor belts, each of said cam rows having spaced cams, each said spaced cam having a high cam surface and a low cam surface; andmeans for rotating said first cam row and said second cam row to alternatingly introduce said first conveyor belts and said second conveyor belts into said wedge-shaped space and into said upper grooves and said lower grooves.
