IMPROVED PLAITING MACHINE.

The principal object the inventors of the machine we illustrate herewith
had in view in designing it was to arrange a mode of working the grip
motion positively, so that the cloth shall be received freely and without
strain or friction before or up to the very instant at which each fold is
completed, and shall then be seized and firmly held. In existing machines
there is not we believe, any arrangement for the accomplishment of this
purpose; it is true, the table upon which the cloth is folded is relieved
at the termination of the stroke of the plaiting knife, but the upper
gripper bar, against which the folds of cloth are pressed upon the return
of the table to its normal position, is stationary, being rigidly fixed
to the sides of the machine. One result of this rigidity is that the
cloth has to be forcibly thrust by the plaiting knife under the upper
gripper bar, and in consequence of the violence involved the fold just
made at the opposite end is dragged out from the grip, making a short
fold, and further, in the case of delicate finishes, giving rise to
damaged goods. Another result of this arrangement, when the cloth is not
pressed against the upper bar, is that it returns with the return stroke
of the plaiting knife, the grip not being made until the knife is clear
of the upper bar; thus the plaits or folds are made of irregular length.
