ABSTRACT:
A right angle folder gluer of the type having a pair of pressure nip rolls at the end of the first folding section and mechanism for transferring each individual and successive blank delivered from the nip into the transfer zone at right angles into the second folding zone, in a direction parallel to the axis of the nip has apparatus for preventing inadvertent re-entry of the blank into the nip during transfer in the form of sharp pointers riding on the upper surface of the blank in rear of the nip to slightly embed therein and unyieldably prevent re-entry while yieldably enabling movement of the blank in the transfer zone in the direction of the second folding section.
