Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A signature loading device to be applied to signature loading apparatus for bookbinding machines comprising a conveyor belt for continuously feeding edge arranged signatures and provided with side guiding members for restraining and guiding said signatures, at the outlet end of said guiding members there being provided a narrowing width portion for bending said signatures with a convexity facing said signature feeding direction and for loading said signatures on a further upwardly slanted conveyor belt, said narrowing width portion engaging said signatures for a heigth substantially equal to that of said guiding members, said narrowing width portion consisting of a pair of endless driven opposite converging belts arranged as extensions of a respective said guiding member, each said converging belt extending between two vertical axis driving and driven rollers, the driven roller of said rollers being adjustably mounted on a respective slotted bracket member.
Claim 2
Dependent Claim

A signature loading device to be applied to signature loading apparatus for bookbinding machines comprising a conveyor belt for continuously feeding edge arranged signatures and provided with side guiding members for restraining and guiding said signatures, at the outlet end of said guiding members there being provided a narrowing width portion for bending said signatures with a convexity facing said signature feeding direction and for loading said signatures on a further upwardly slanted conveyor belt, said narrowing width portion engaging said signatures for a heigth substantially equal to that of said guiding members, said narrowing width portion consisting of a pair of endless driven opposite converging belts arranged as extensions of a respective said guiding member, each said converging belt extending between two vertical axis driving and driven rollers, the driven roller of said rollers being adjustably mounted on a respective slotted bracket member.
Claim 3
Dependent Claim
54 words
A signature loading device according to claim 1 wherein said narrowing width portion consists of a converging portion integrally formed with said guiding members, and having a heigth substantially equal to that of said guiding members, said signature driving means consisting of feeding vertical axis rollers arranged at the outlet of said converging portion.
Claim 4
Dependent Claim
83 words
A signature loading device according to claim 1 wherein said narrowing width portion consists of a pair of baffle wings arranged as extensions at the outlet portions of said guiding members and having a heigth substantially like to the heigth of said guiding members, said wings being supported by slanted rods in such a way as to be able of reciprocating and translating, said signature driving means consisting of entraining belts and rollers engaging with the top edge of said signatures being fed.
Claim 5
Dependent Claim
52 words
A signature loading device according to claim 2 wherein a signature tilting endless belt is provided at the outlet of said narrowing width converging portion, said tilting belt being provided with lugs effective to engage with the top edges of said bent signatures for tilting them on said upwardly slanted conveyor belt.
Claim 6
Dependent Claim
57 words
A signature loading device according to claim 1, wherein, at the outlet end of said upwardly slanted conveyor belt, there is provided a further conveyor belt of adjustable length for fitting said upwardly slanted conveyor belt to a signature processing apparatus, said adjustable length conveyor belt being entrained on a roller rotatably supported on a movable frame.
