Apparatus for separating card strips during carding of fibrous materials

Claim 1

Apparatus for removing card strips, such as fiber naps, fiber adhesions, short fibers, foreign particles, waste fibers and the like from fibrous material during a carding operation comprising a carding cylinder carrying carding means in opposed relationship to carding means disposed about the exterior of said carding cylinder, means for rotating said carding cylinder whereby said carding means cooperatively perform a carding operation upon fibrous material conveyed through the apparatus by said rotating carding cylinder, means for directly removing card strips from the fibrous material carried by the rotating carding cylinder independent of said carding means but during the performance of said carding operation by said carding means, said removing means including a strips roller disposed adjacent said carding cylinder and defining therewith a gap through which said fibrous material is carried by said rotating carding cylinder, means for rotating said strips roller, vacuum means for removing card strips from said strips roller, stripper plate means contiguous said gap for dividing the fibrous material into two portions from only one portion of which is removed the card strips by said strips roller, means for adjusting the position of said stripper plate means to selectively alter the amount of fibrous material in each of said two portions whereby a select precentage of card strips are removed from said fibrous material depending upon the amount of fibrous material in said only one portion, said removing means includes another strips roller disposed adjacent said first-mentioned strips roller and adjacent said carding cylinder, said another strips roller and carding cylinder define another gap through which said fibrous material is carried by said rotating carding cylinder, means for rotating said another strips roller, said vacuum means being operative to remove card strips from said another strips roller, and said stripper plate means being disposed between said first-mentioned and another strips roller.
