Bloch, Jacob

fl. 1888
European inventor of a machine for cutting layers of cloth.
In mass production of garments, layers of cloth are laid out on top of each other and multiples of each different part are cut out at the same time. The first portable cutting machine was invented by Joseph Bloch in 1888. It was operated from a DC electricity supply and had a circular knife, which was difficult to use when cutting round curves. Therefore the cloth had to be raised on curves so that it would reach the furthest part of the circular blade. In the same year in the USA, G.P.Eastman produced a vertically reciprocating cutting machine with a straight blade.
