Abstract: A personal binding machine for assembling a preformed coil into a stack of prepunched sheets which includes a loading tube assembly that properly orients the coil to be driven into the stack of sheets, a drive assembly which drives the coil into the stack of sheets, and crimping assemblies for crimping the ends of the coil once inserted into the sheets. The drive assembly includes a three surface contact system having a coil guide substantially adjacent the edge of the stack of sheets, a drive roller and an idler roller. While the coil guide is stationary within the housing, the location of the drive and idler rollers may be adjusted via a camming system to accommodate various coil sizes. The crimping assemblies include a cradle and blade mechanism wherein the blade presses an end of the coil into a cradle to bend or crimp the end. The drive roller may alternately be directly accessed to manually drive the coil through a stack of sheets.
