Sliv′er-box.
The machine in which slivers of [2214] long-stapled wool are lapped on each other and then elongated. It is like the drawing-frame of the cotton manufacture, except that the slivers of worsted being made by hand-cards, taper toward each end and are not continuous. Each sliver is laid upon the one preceding, so that its end reaches to the middle of the one in advance. The rate of acceleration of the relative speeds of the pairs of rollers is such as to make a uniform sliver eight times the length of the slivers as fed into the first pair of rollers.Finishing-card. |
