ABSTRACT:
A hole-punching and binding apparatus for papers includes a hole-punching device drivable to move along a vertical direction. The hole-punching device includes a cutter seat carrying thereon a number of cutters that are equidistantly spaced in a row to punch a row of holes in a stack of papers. Each cutter being freely movable in a row of compartments in the cutter seat so as to optionally follow a hole-punching travel of the cutter seat under control of a slidable shield. A lever-like resilient load-on plate is used to press and thus close open ends of helical coils and to help the user extend the helical coils through a stack of punched papers. The coil-closing device is drivable to move along a horizontal direction. The coil-closing device cooperates with a fixed plate to turn the open ended helical coils into closed ended helical coils.
