Abstract

A machine for binding a packet of sheets of binding elements has a transfer belt designed to magnetically fix the binding elements and to move between a disengagement position in which it receives the binding elements and an engagement position in which it is positioned in a closure zone, closure devices disposed upstream of the transfer belt and designed, in the closure zone, to close the elements, a magnetic binding table disposed upstream of the closure devices, and comprising a fixing zone for holding a series of ends of the elements, and a magnetic top guide disposed upstream of the closure devices and above the binding table, and comprising a fixing zone for holding the other series of ends of the elements, the packet of perforated sheets being inserted between the table and the top guide.

Claims18

Dependent claims

Machine for binding a packet of perforated sheets using metal binding elements formed by a series of curved fingers and comprising a first series of ends forming points, a second series of ends forming bases, and intermediate zones connecting the first ends to the second ends, the binding machine comprising:

a transfer belt mounted on a transfer assembly and designed to magnetically fix the binding elements at the intermediate zones, the transfer assembly comprising movement means designed for moving said transfer belt between a disengagement position in which the transfer belt is not positioned in a closure zone and receives the binding elements and an engagement position in which the transfer belt is positioned in the closure zone,
closure means disposed upstream of the transfer belt and designed, in the closure zone, to close the binding elements by crushing when the transfer belt is in the disengagement position,
a magnetic binding table disposed upstream of the closure means, the magnetic binding table comprising a fixing zone designed to magnetically hold a first one of the two series of ends, and
a magnetic top guide disposed upstream of the closure means and above the magnetic binding table, the magnetic top guide comprising a fixing zone designed to magnetically hold a second one of the two series of ends, the packet of perforated sheets being inserted between the magnetic binding table and the magnetic top guide in the closure zone.

Method of binding a packet of perforated sheets by means of metal binding elements formed by a series of curved fingers and comprising a first series of ends forming points, a second series of ends forming bases, and intermediate zones connecting the first ends to the second ends, the binding method being executed by a binding machine and comprising the steps of:

supplying binding elements on a magnetic transfer belt disposed in a disengagement position,
running the magnetic transfer belt with the binding elements thus supplied so as to position the binding elements with respect to positions of perforations of the sheets,
moving the magnetic transfer belt to an engagement position in a closure zone,
inserting the packet of perforated sheets in the closure zone between a magnetic binding table and a magnetic top guide, with the magnetic binding table and the magnetic top guide being disposed upstream of the magnetic transfer belt,
moving the magnetic transfer belt to the disengagement position,
closing the binding elements by closure means disposed upstream of the magnetic transfer belt and downstream of the magnetic binding table and the magnetic top guide,
moving the whole of the magnetic transfer belt to the engagement position,
running the magnetic transfer belt so as to eject the bound assembly from the binding machine,
moving the magnetic transfer belt to the disengagement position, and
looping back onto the step of supplying binding elements.
