Designing the Big Squeeze |
||||
|
|
The purpose of a book press is to apply pressure and to distribute it evenly. |
||||
|
In a bookbinding press, the screw applies the pressure and the platen distributes it. The amount of pressure applied to the work and its even distribution is a function of design. Ideally, the effort applied at the handwheel should be multiplied by the mechanical advantage of the screw/handwheel combination and translate into a weight evenly distributed across the surface of the object pressed. However, mechanical inefficiencies can easily reduce the ideal mechanical advantage by as much as 75%. If the platens are poorly designed the remaining 25% may be concentrated on the center of the pressed object with only minimal pressure at its periphery. The handwheel/screw of The Big Squeeze is designed to maximize efficiency while the platens are designed to maximize weight distribution.
