Abstract
An apparatus for applying covers to books of signatures transported along a binding line includes cover feeders for feeding at least two covers upon a conveyor line and a fastening arrangement for joining the covers in substantially superimposed registration on the signatures at a covering station on the binding line. A spacer bar is supported on the conveyor line for temporarily separating the covers before they are joined to the signatures.
Claims22
A method for applying covers to at least one signature transported along a binding line, said binding line having a covering station, the method comprising the steps of:
- delivering at least a first cover to a conveyor means;
- delivering at least a second cover to said conveyor means;
- and
- joining said first cover and said second cover together in substantially flattened, substantially superimposed registration on said at least one signature at said covering station.
A method for applying covers to at least one signature transported along a binding line, said binding line having a covering station, the method comprising the steps of:
- delivering at least a first cover to a conveyor means;
- delivering at least a second cover to a conveyor means in substantially flattened, substantially superimposed registration substantially adjacent said first cover;
- temporarily spacing said first cover and said second cover;
- joining said first cover and said second cover together in substantially flattened, substantially superimposed registration;
- and
- applying said first cover and said second cover joined together to said at least one signature at said covering station.
A method for applying covers to a book of signatures transported along a binding line, said binding line having a covering station, the method comprising the steps of:
- delivering at least a first cover to a conveyor means;
- applying at least a first adhesive to said first cover;
- providing at least a second cover to said conveyor means in substantially superimposed registration substantially adjacent said first cover;
- temporarily separating said first cover and said second cover from each other during said providing;
- joining said first cover and said second cover in substantially superimposed registration by means of said first adhesive to form a cover assembly;
- applying a second adhesive to said book;
- and
- applying said cover assembly to said book.
An apparatus for delivering covers to a conveyor means and applying said covers to at least one signature, said at least one signature being transported along a binding line, said binding line having a covering station, the apparatus comprising:
- cover feeding means for feeding at least a first cover and a second cover upon said conveyor means;
- and
- fastening means for joining at least said first cover and said second cover in substantially superimposed registration on said at least one signature at said covering station.
An apparatus for delivering covers to a conveyor means and applying said covers to books of signatures transported along a binding line, said binding line having a covering station, the apparatus comprising:
- first cover feeding means for feeding at least a first cover to said conveyor means;
- second cover feeding means for feeding at least a second cover in substantially flattened, substantially superimposed registration substantially adjacent said first cover on said conveyor means, said second cover feeding means being downstream of said first cover feeding means;
- spacer means for temporarily separating said first cover and said second cover, said spacer means being located along said binding line intermediate said second cover feeding means and said covering station;
- fastening means for joining said first cover and said second cover in substantially superimposed registration, said fastening means being located downstream of said spacer means intermediate said second cover feeding means and said covering station;
- and
- application means for applying said first cover and said second cover to said books at said covering station.
