5 Card Cutting
To punch the holes in jacquard cards, according to specified designs, and in the order they are to operate the needles. There are two types of machines used, the plate and the piano. Plate Machine - The operation on this machine is slow, the plate being usually reset for every distinct pick in the design; but if there are many similar picks in the design it is obviously the quicker, as one setting of the plate will enable all similar picks to be cut in a few moments. Piano Machine - This machine feeds the card into the line of 8, 10, or 12 cutting punches controlled by the fingers, so that the fingers indicate the correct punches; one foot cuts and the other foot (or treadle) controls the movement forward of the card. A good cutter will cut from 100 up to 120 cards per hour (300's cards). The sketch shows this machine
