Matrix pendulum de-burring machine, Plant No.2084, made by The Monotype Corporation Ltd., Salford, Redhill, Surrey, 1955. Equipped for the automatic feed of matrices from input to output galleys, part of the production system for 0.2 x 0.2-inch Monotype matrices, for the hand-finishing the character face and for the counter-sinking of the cone. Mounted on bench with machines Nos. 1134 and 2958.

There are 82 separate processes needed to transform a designer’s drawing (of a letter, figure, punctuation, or symbol) into a piece of Monotype metal type for printing. A pantograph is used to trace and cut the letter from a copper pattern into a piece of steel called a punch. After being hardened, the punch is driven into a piece of bronze using a crank press to produce a matrix. The finished matrix is ready to go to the Monotype Composition Caster where molten metal is pumped through a mould against the matrix to produce a piece of type.

This machine is one of many machines used in the process to make a 0.2 inch or 0.4 inch matrix.

The Type Archive has a functioning Monotype matrix workshop containing around 70 machines and pieces of equipment. It is the only one of its kind in the world and matrices are still produced for customers.
