Abstract:
1. 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.
