A machine for binding a sheath of punched sheets together by means of a spine binder includes a closing assembly for closing the spine binder over the sheath of punched sheets. The closing assembly includes a rail and a closing tool carried by and movable along the rail, and adapted to engage the spine binder for closing the spine binder over the sheath as the closing tool is moved along the rail.

Binding machine and method

Devices for hanging a display board frame wherein a first bracket is mounted on a wall and has a hook on one end supportingly engaging a channel on a corresponding first edge of a display board frame and a second cooperating bracket having a slotted portion is slidingly mounted on the wall in a position corresponding to a second edge of the display board frame spaced apart and opposed to the first display board edge and the second bracket has a hook on its end in alignment with a channel on the second edge of the display board frame; and the display board is releasably secured on the wall when the upper bracket is slid against the display board frame until its hook engages the channel on the second edge of the display board frame, The invention also includes a method for hanging a display board frame including the steps of securing the first bracket on the wall with its hook engaging the channel on one edge of the frame, securing the second slotted bracket on the wall with its hook spaced away from the second edge of the frame, and sliding the second bracket against the channel on the second edge of the frame to secure the frame on the wall.

The present invention provides an unitary spine binder which comprises an elongated dorsal hinge bearing pairs of opposing and complementary male and female ring elements having known male fastener and female fastener, respectively. Each pair of ring elements also comprise a concave distal end on one element, and a complementary convex distal end on the other element. When the distal ends of the ring elements are moved towards each other, the male and female fasteners reversibly engage with each other so that each pair of ring elements, in cooperation with the dorsal hinge, forms substantially a ring to secure sheet paper by occupying a pre-punched hole in the paper. At the same time, the concave and convex distal ends also engage, so that the sidewalls of the concave distal end engages the convex distal end to protect the fasteners against disengagement by torsional and lateral forces.
