ABSTRACT:
The disclosed apparatus is capable of uniting a cover with a sheaf of pages having through holes at purely optional locations. A flexible stem binds the pages and has its ends engaged by separate runners positioned adjacent the sheaf. The cover is connected to the runners at a position opposite the sheath so that the stem ends need not pass through the cover. The elastic flexibility of the stem permits the cover to open without bending.
