disappear as the fibre proceeds on its way through the different
machines. [Illustration: FIG. 8 BALE OPENER _By permission of Messrs. Urquhart, Lindsay & Co., Ltd_.] The layers of heads are often beaten with a heavy sledge hammer in hand batching, but for machine batching a bale opener is used, and this operation constitutes the preliminary opening. As already indicated, the heads of jute are fed into the machine from the left in Fig. 8, each head being laid on a travelling feed cloth which carries the heads of jute successively between a pair of feed rollers from which they are delivered to two pairs of very deeply-fluted crushing rollers or breakers. The last pair of deep-fluted rollers is seen clearly on the right in the figure. These two pairs of heavy rollers crush and bend the compressed heads of jute and deliver them in a much softer condition to the delivery sheet on the right. The delivery sheet is an endless cloth which has a continuous motion, and thus the softened heads are carried to the extreme right, at which position they are taken from the sheet by the operatives. The upper rollers in the machine may rise in their bearings against the downward pressure of the volute springs on the bearings; this provision is essential because of the thick and thin places of the heads. A different type of bale opener, made by Messrs. Charles Parker, Sons, & Co., Dundee, and designed from the Butchart patent is illustrated in Fig. 9. It differs mainly from the machine illustrated in Fig. 8 in the shape of the crushing or opening rollers. |
