Definitions

  • This invention relates to a knitting cam and a cam apparatus for forming stitches of different sizes in the same course of knitting.
  • stitches can be transferred between at least a pair of needle beds provided at the front and at the rear and can also be transferred transversely by shifting the positions of the front and rear needle beds leftwardly and rightwardly.
  • An arbitrary knitted texture can be knitted by making use of those functions.
  • fully-fashioned knitting to knit a fabric of an arbitrary shape can be performed by transferring formed stitches between front and rear needles to suitably change the knitting width in accordance with the shape of a fabric to be knitted.
  • a knitted fabric need not be cut after being knitted. Consequently the cutting step can be omitted and the knitting yarn used in that portion which is conventionally discarded at the cutting step after the completion of the knitting of the knitted fabric can be saved. Consequently, the production costs can be reduced.
  • FIGS. 10A and 10B One conventional method of forming stitches of different sizes, large and small, is shown in FIGS. 10A and 10B.
  • FIG. 10A shows a conventional knitting cam and FIG. 10B is a sectional view taken along line G-G of FIG. 10A.
  • a common lowering cam face 102 having a great thickness for engaging both a needle for the formation of a small stitch and a needle for the formation of a large stitch, and a stitch size determining cam face 103 for a large stitch contiguous with the common lowering cam face 102 and having a small thickness are provided on a knitting cam 101.
  • the stitch size determining cam face 103 for a large stitch is formed with such a thickness that it is engaged only by a butt which is projected to its upper limit by a respective presser.
  • Each of the butts of a needle for the formation of a small stitch and of a needle for the formation of a large stitch is first raised, upon movement of a carriage, to its most raised position by a needle raising cam passing the same locus, and then, during a lowering movement thereof, a knitting yarn is supplied to the hook of the needle. Then, each of the butts of the two needles is engaged by and lowered by a knitting cam.
  • the butt of the needle for the formation of a small stitch is put, by a known presser mechanism, into a condition sunk in a respective needle groove to a height at which the butt is not engaged with the stitch size determining cam face 103 for a large stitch having a small thickness, so that, of the needle for the formation of a small stitch and the needle for the formation of a large stitch having been lowered by the knitting cam 101 till then, only the needle for the formation of a large stitch is continued to be lowered by the stitch size determining cam face 103 for a large stitch, while the needle for the formation of a small stitch is not engaged by the stitch size determining cam face 103 for a large stitch and thus moves in a horizontal direction relative to and along a lower edge of the common lowering cam face 102.
  • a receiving cam for restricting excessive movement of a needle is conventionally provided at a position corresponding to the terminal end of a lowering face for moving the butt of a needle.
  • the stitch size determining cam face 103 for a large stitch is formed on the same line as the common lowering cam face 102 for lowering both of a needle for the formation of a small stitch and a needle for the formation of a large stitch, a receiving cam for restricting downward movement of a needle for the formation of a small stitch cannot be provided, and a receiving cam 105 is provided only for the needle for the formation of a large stitch which is lowered by the stitch size determining cam face 103.
  • the knitting cam is constructed so that the movement of the butt of a needle for the formation of a small stitch changes from a downward movement to a movement in a horizontal direction relative to the knitting cam at the location of the terminal end 104 of the common lowering cam face, since no receiving cam is provided, the butt of the needle may possibly be moved further downwards than the terminal end 104 of the common lowering cam face by inertia acting upon the needle. If the needle for the formation of a small stitch is moved downwards further than the terminal end 104 of the common lowering cam face in this manner, a small stitch is formed with a similar size to that of a large stitch, resulting in the problem that such small and large stitches cannot be distinguished from each other.
  • a knitting cam for engaging with butts for controlling forward and backward movements of needles projecting by different amounts in order to form a small stitch and a large stitch in the same course, characterised in that the knitting cam is provided with a common lowering cam face for lowering the butts of both the needle for the formation of a small stitch and the needle for the formation of a large stitch, a stitch size determining cam face for a small stitch contiguous to said common lowering cam face, and a stitch size determining cam face for a large stitch located rearwardly of said stitch size determining cam face for a small stitch and having a smaller thickness than said common lowering cam face for acting upon a butt which projects to a greater extent, and in that the cam is further provided with lowering movement restricting means for restricting the maximum lowered position at least of the needle for the formation of the small stitch.
  • the knitting cam is further characterised in that it is provided with lowering movement restricting means for restricting the maximum lowered positions of both the needle for the formation of a small stitch and the needle for the formation of a large stitch.
  • the lowering movement restricting means may comprise a receiving cam face provided at an upper end portion of said knitting cam.
  • the lowering movement restricting means may comprise a pair of receiving cams provided at opposing positions at a lower end portion of said knitting cam with a passageway for a butt interposed therebetween.
  • a cam apparatus for forming a small stitch and a large stitch in the same course of knitting, characterised in that the apparatus comprises a knitting cam for engaging with butts for controlling forward and backward movements of needles projecting by different amounts, said knitting cam being provided with a common lowering cam face for lowering the butts of both the needle for the formation of a small stitch and the needle for the formation of a large stitch, a stitch size determining cam face for a small stitch contiguous to said common lowering cam face, and a stitch size determining cam face for a large stitch located rearwardly of said stitch size determining cam face for a small stitch and having a smaller thickness than said common lowering cam face for acting upon a butt which projects to a greater extent, said knitting cam being further provided with lowering movement restricting means for restricting the maximum lowered position at least of the needle for the formation of a small stitch, and pressing means for pressing down the butts of the needle for the formation of a small stitch to a level at which the
  • the knitting cam is provided with lowering movement restricting means for restricting the maximum lowered positions of both the needle for the formation of a small stitch and the needle for the formation of a large stitch.
  • both the needle for the formation of a small stitch and the needle for the formation of a large stitch are lowered on the same locus by the common lowering cam face of the knitting cam positioned on the trailing side in the direction of advance of the carriage.
  • both the needle for the formation of a small stitch and the needle for the formation of a large stitch are prevented from being further lowered by the lowering movement restricting means and thus move in a horizontal direction relative to the knitting cam along the stitch size determining cam face for a small stitch.
  • both the needle for the formation of a large stitch and the needle for the formation of a small stitch arrive at the stitch size determining cam face for a large stitch having a small thickness, and there, since the butt of the needle for the formation of a small stitch is sunk slightly into its needle groove, it moves in the horizontal direction relative to the knitting cam without engaging with the stitch size determining cam face for a large stitch.
  • the needle for the formation of a large stitch is lowered further downwards by the stitch size determining cam face for a large stitch.
