Abstract
A book binding sleeve accessory receives, aligns, grips, and holds an unbound stack of pages before and during a book binding process. The accessory has an arc-shaped inner bottom wall bridging and connecting between two generally opposing and similarly sized rectangular planar side walls that respectively depend away from said bottom wall and incline towards one another and terminate in two respective and proximate top free edges establishing an at rest position and said side walls can be flexed to a flexed apart position to receive interposed between said side walls an unbound stack to be bound. Preferably the side walls are offset to assist in shaping an unbound stack to align binding holes to match the pitch of a spiral coil used to bind the stack.
