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. A registration arrangement maintains the alignment of the covers upon the conveyor line.
Claims7
An apparatus for feeding covers in a binding system, the apparatus comprising
- means for delivering at least a first cover to a conveyor line, the first cover having a trailing edge and a pair of side edges defining a first cover width, and for delivering a second cover to the conveyor line, the second cover having a trailing edge and a pair of side edges defining a second cover width, and
- means for guiding the first and second covers into substantially superimposed relation when the first and second covers are moved to the conveyor line, the means for guiding the first and second covers including registration means engageable with the respective trailing edges of the first and second covers and engageable with the respective side edges of the first and second covers and for maintaining said covers in substantially superimposed alignment on the conveyor line, the registration means being adaptable to accommodate first and second covers defining unequal first and second cover widths.
An apparatus for delivering covers having respective side edges to a conveyor means and for applying the covers to at least one signature, the apparatus comprising:
- cover feeding means for delivering at least a first cover and a second cover upon the conveyor means;
- registration means for effecting substantial registration of the first cover and the second cover and for maintaining the first and second covers in substantially superimposed registration on the conveyor means, said registration means including a pair of laterally spaced-apart, elongated cover guides adapted to engage the respective side edges of one of the first and second covers,
- means for supporting said cover guides and for affording variation of the lateral spacing of said pair of cover guides;
- and
- fastening means for joining at least said first cover and said second cover in substantially superimposed registration on said at least one signature.
An apparatus for feeding at least a first cover and a second cover in a binding system including a conveyor line carrying at least one signature, the first and second covers each having a pair of spaced-apart side edges defining a cover width, a leading edge, and a trailing edge, the apparatus including:
- cover feeding means for delivering at least a first cover and a second cover upon the conveyor line;
- registration means for effecting substantial registration of the first cover and said second cover and for maintaining the first and second covers in substantially superimposed registration on the conveyor line, said registration means including a pair of elongated, laterally spaced-apart cover guides, and said registration means including adjustable means for supporting said pair of cover guides and for affording variation of the lateral spacing of said pair of cover guides, said adjustable means including means for independently positioning each respective cover guide;
- and
- fastening means for joining at least said first cover and said second cover in substantially superimposed registration on the at least one signature.
