For a mode of making Woollen Roping, or Stubbing, by the " Spiral Slubbing Machine;" Austin Steele, Waterbury, New Haven county, Connecticut, April 1.
The main cylinder, doffers, combs, and small rollers, in this machine, are represented exactly like those in the drawing accompanying Mr. Charles Atwood's specification; but instead of the tubes between the doffers and small rollers, the wool, as it is separated by the combs, is received upon a short revolving apron; it passes along this apron, across which " is another apron, or belt, which presses upon and revolves on the said web, and rolls, or twists it; or a roller, working obliquely, may be used for the same purpose. The effect produced by the motion of the upper apron or roller, is to twist or roll up the roping or slubbing spirally." The claim is to " the mode of making woollen roping, or stubbing, by rolling it up spirally, as above described." Mr. Atwood refers to this mode of rubbing, and objects to it, as producing a degree of felting injurious in the subsequent operations upon the slubbing, and upon the fabric manufactured from it; so far as we may be allowed to judge without experience, we are inclined to prefer Mr. Atwood's plan.
