LEAD CUTTER.

A mitering machine and lead-cutter are among the necessary adjuncts of a printing-office.

Perforating Rule is slightly higher than type, and is used in printing coupons and tickets which require to be partially severed while going through the press. It is made of brass or steel. A more convenient (as well as more expensive) article is Ames’s Patent Perforator: its knife, or perforator, lies below the surface of the type while the rollers pass over the form, and rises and makes a clean cut when the impression is on, without injuring the rollers.

Machines for perforating round holes are manufactured of several sizes. The lowest-priced machine may be worked on a counter, and will perforate every kind of card-board or paper. We give a cut of this style.
