The machines used for rubbing the seams out for " bagged" or " stitched-on and turned-over edge" work are known as bagging or beading machines. There are two types in general use, the Watson and the Columbia. The former consists of a couple of fingers made to press out the seam, and on a line with this arrangement is the hammer for hammering same flat. The latter machine has the folding-out levers arranged in front of the anvil and hammer, enabling smaller curves to be operated upon with greater freedom.
