Description

June 18, 1. I
Filed Sept. 7, 1958 arrangement the discs Ia and 2a are rotated in synohronism by a driven gear l8 which meshes with a gear wheel secured on a shaft carrying the beveled gear IS. The geveled gear l4 engages thebeveled gear teeth of the gear l6 and thus rotates the shaft 4 and the disc 2a which drives the disc la by means of the teeth 5a. The knife 9 secured to the shaft I1 is rotated in synchronism with the discs la and 20. by means of a gear [9 which meshes with the driven gear l8.
A plurality of cutting devices such as shown in Figs. 2 and 6 may be arranged adjacent each other as illustrated in Fig. 3 wherein the severed pieces of the fibrous material are delivered onto moving bands M which converge so as to group the separated pieces. The timing of the individual cutting devices'may be so adjusted that the cuts in the various strands do not conincide but are staggered as illustrated in Figs. 4 and5.
While detailed structural arrangements have been described for carrying out the invention it is apparent that changes may be made therein and modifications may be adopted without departing from the spirit and scope of the invention as set forth in the appended claims.
I claim:
1. Apparatus for cutting fibrous strands of artificial filaments comprising, two discs having circiunferentially spaced recesses in the peripheries thereof. said discs being arranged with the faces thereof adjacent each other and with the axis inclined with respect to each other so that the inner faces of the discs adjacent the peripheries thereof engage the fibrous strand. an annular projection carried by one of the discs adjacent the periphery thereof and projecting towards the other disc for supporting the fibrous strand, and a rotating knife having a screw shaped cutting edge arranged to ass through said recesses of both discs and out said filaments while the strand is engaged by the inner faces of the discs.
2. Apparatus for. cutting fibrous strands of artificial filaments comprising, two discs having circumferentially spaced recesses in the peripheries thereof, said discs being arranged with the faces thereof adjacent each other and with the axes inclined with respect to each other so that the inner faces of the discs adjacent the peripheries thereof engage the fibrous strand. a plurality of teeth carried by each disc adjacent the periphery thereof and projecting towards the other disc for supporting the fibrous strand and engaging each other, and a rotatable knife having a screwshaped cutting edge arranged to pass through the recesses of both discs and out said filaments while the strand is engaged by the inner faces of the discs.
3. A method of severing fibrous strands of artificial filaments which comprises, continuously moving the strand, bending the strand, clamping the bent strand adjacent a point where the filaments are to be cut, progressively severing the outer filaments and the inner filaments of the bent strand while the filaments are thus clamped.
4. A method of severing fibrous strands of artificial filaments which comprises, continuously moving the strand, laterally gripping the strand adjacent points where the filaments are to be severed, and draw cutting the strand in a direction oblique to the axis of the strand at spaced intervals while the filaments are thus gripped.
5. A method of completely severing fibrous strands of artificial filaments which comprises, continuously moving the strand, bending the strand in an arcuate form during movement thereof, laterally gripping the arched strand adjacent a point where the filaments are to be severed, drawing a cutting edge transversely through the filaments at the outer circumference of the arched strand radially inward through the remaining filaments while the filaments are laterally gripped.
6. A method of severing fibrous strands of artificial filaments comprising, continuously moving the strand, bending the strand along its longitudinal axis in an arcuate shape to tension outer filaments with respect to the inner filaments of the strand, clamping the strand adjacent a point where the filaments are to be cut, and drawing a knife edge obliquely through the outer filaments and moving the knife edge obliquely and radially inward to sever the inner filaments.
