A modern breaker card is illustrated in Fig. 14. The feed or back of
the card is on the extreme right, the delivery or front of the card on the extreme left, while the gear side of the card is facing the observer. The protecting cages were removed so that the wheels would be seen as clearly as possible. Some of the stricks of fibre are seen distinctly on the feed side of the figure; they are accommodated, as mentioned, in a channel-shaped stand on the far side of the inclined feed sheet, or feed cloth, which leads up to and conveys the stricks into the grip of the feeding apparatus. This particular type is termed a "shell" feed because the upper contour of the guiding feed bracket is shaped somewhat like a shell. There is a gradually decreasing and suitably-sized gap between the upper part of the shell and the pins of the feed roller. The root ends of the pins in this roller lead, and the stricks of fibre are gripped between the pins and the shell, and simultaneously carried into the machine where they come into contact with the points of the pins in the rapidly-revolving large roller, termed a cylinder. The above-mentioned combing and splitting action takes place at this point as well as for a distance of, say, 24 inches to 30 inches below. The fibres which are separated at this stage are carried a little further round until they come into contact with the points of the pins in the above-mentioned slowly-moving roller, termed a "worker," and while the fibres are moving slowly forward under the restraining influence of the worker, they are further combed and split. A portion of the fibres is carried round by the pins of the worker from which such fibres are removed by the quicker moving pins of the second roller of the pair, termed a |
