ABSTRACT:
Loader for signatures and the like, comprises, between the signature feeding path and the signature raising path, a step capable of breaking and dividing the signature pack, so as to form a stack portion of very reduced weight. The adhesion of the signatures to be conveyed on the raising path is improved by applying a negative pressure. There is further provided a sensor for detecting the presence of signatures on the raising path which sensor is swingably supported and is capable of acting as an abutment for the signatures forming the pack portion.
