Abstract: The invention relates to a signature hopper loader and method for feeding signatures to a hopper on a binding line. The hopper loader includes a conveyor and a deblocker that work together to feed signatures to the hopper. The deblocker is preferably positioned adjacent the conveyor such that the deblocker serves to laterally shift the signatures facilitating deblocking and/or alignment of the signatures.

Abstract: The invention provides for an improved signature hopper loader for feeding signatures to a hopper on a binding line. The hopper loader includes two conveyor assemblies that work together to feed signatures to the hopper. The first conveyor assembly is connected to the second conveyor assembly such that there is an angle in the range of 110-120 degrees between the first and second conveyor assemblies. The first and second conveyor assemblies also include forming guides that serve to fan, or deblock, the signatures that are traveling along the first or second conveyor assembly. As the signatures travel over the forming guides, they are bent to give the signatures rigidity and to further facilitate deblocking. The hopper loader further includes an opposing belt that is held on top of at least a portion of one of the transporting belts. The opposing belt is hinged to the frame of the hopper loader and preferably swings down on top of the center belt in the second conveyor.
