It is well known that woolen rovings in their untwisted state, cannot, at present, be used for weaving, knitting, c, but have previously to go through what may be called a spinning process, by which the fibres ot the wool are twisted together. John H. Blood-good, of Rahway, Essex Co., N. J., has taken measures to secure a patent, by which the rovings can be used for weaving without the necessity of performing the above operation, simply by felting them as they come from the carding machine. This is done by steaming the rovings, and at the same time applying a pressure which, by its peculiar action, felts them together into a thread fit for any purpose for which twisted threads are now employed. The advantages are the cheapness of the process, as all the expenses of spinning are saved, and the fabrication of a material that may be advantageously employed as a weft when cotton warping is used. Cloth made of this felted roving thread, it is stated, is more easily knapped by the teasks, and also . takes a finer finish in the dressing. It should be understood that no new improvements in machinery are claimed.
