Bolster

A piece of wood placed between the ribs of a press to prevent the table running out too far, and to ease the sudden strain which would otherwise be caused on the girthing. Also a contrivance consisting of hard paper rolled up and pasted on to the frisket, to guard the outsides of light and open pages when there is an inclination to slur. In a forme of border rules they are laid in the middle of the pages each time after the forme is rolled, to prevent the sheet from being soiled by dipping upon the furniture. Some Pressmen use cork for this purpose; others use sponge, which, from its elasticity, is very useful.
