  • This invention relates to a digitally controlled translational movement, in particular for controlling the guide bars of warp knitting machines.
  • pattern chains have been used to control the guide bars of warp knitting machines, in particular the weft thread guide bars (pattern guide bars) which determine the pattern of the texture by their position.
  • pattern chains run over a drive pulley past the rams of the guide bars.
  • the corresponding ram and with it the guide bar is shifted to a greater or lesser extent.
  • the length of the pattern chains may be substantial and may, above all, be of different lengths for the individual guide bars so that a considerable amount of apparatus is required.
  • the controls of the guide bars are effected by particularly shaped mechanical structures, namely, the pattern elements, since the manufacture of these pattern elements requires a great amount of labor and time.
  • this object is attained by using spacers having different widths (dimensions in a given direction) to obtain different valences of the digital information.
  • the informational instructions are employed to select particular spacers and arrange them successively so that their widths add up to produce the translational movement of the guide bar required for that part of the pattern.
  • a further modification of this invention is characterized in that the spacers have a position of rest from which the spacers required (when converting a pre-established digital information) are moved into an operating position which is disposed between a drive effecting the shifting and an index.
  • a pattern to be knitted is, for example, established in digital form on an information media such as a kind of Jacquard card, punched tape, or the like. From this coded card or tape, electromagnets are controlled in a known manner to effect the movement of the spacers.
  • a plurality of spacers l, 2, 4, 8 and 16 are employed. Each has a different width, i.e., vertical dimension as seen in the drawing. These widths are digitally related to each other.
  • the spacers 1, 2, 4, 8 and 16 have respective widths l l l l and I
  • the spacer 1 represents the value 2
  • the spacer 2 the value 2, etc.
  • the spacers have a position of rest 25 (in which they are inoperative) and an operative position 26. They are moved from the inoperative to the operative position by respective electromagnets M1, M2, M4, M8 and M16 when the latter are energized.
  • the spacers l, 4 and 16 are in their operative positions corresponding to a binary number LOLOL.
  • the cam 20 For converting this binary number into a translational movement, the cam 20 is rotated as indicated. The cam shifts the spacers 1, 4 and 16 against the bolt 21.
  • Bolt 21 (mounted for axial movement in a frame 24) has a position of rest (or zero position) against the stop 22 to which position it is urged by the spring 23. Continued cam movement forces the bolt upwardly by the sum of the widths of the spacers I I 1, Thus, the digital value is converted into a translational movement of a given increment. If no spacer is in its operating position, the bolt will not be shifted upon rotation of the cam or will be shifted only by a minimum fixed value. To improve the sliding movement of the cam 20 when the spacers are shifted, a roller 28 and a plate 27 are employed. Shifting of the bolt 21 may be used for the control of various operations.
  • the guide bar of a warp knitting machine may be controlled by means of the bolt. As is known, the guide bars are shifted during the knitting process to produce patterns.
  • a pattern being knitted is coded in digital values into an information means such as a form of Jacquard card, etc.
  • the information is then automatically taken from the coded card to control the energizing of the electromagnets which select the spacers.
  • an arrangement such as that illustrated and described, is required for each guide bar.
  • Each arrangement, according to the invention is designed narrow so that they can all be positioned closely together in a row.
  • the speed at which the cam rotates is defined by the working rhythm of the warp knitting machine which also determines the times of interrogation of the coded card.
  • a warp knitting machine having a movable guide bar and a device for moving said guide bar in different and predetermined strokes, the improvement comprising:
  • a bolt having an end and an axis, means guiding said bolt for axial movement, a spring contacting said bolt and resiliently urging said bolt in a direction such that said end is forwardly to a position of rest, a stop positioned to contact a portion of said bolt and prevent said bolt from moving in said direction beyond said position of rest, actuating means having a part having a relative motion toward and away from said end, said actuating means being positioned beyond said end when said end is at said position of rest to define a space therebetween, a plurality of individually movable spacers each having a specific dimension in a given direction, said dimensions of the spacers being digitally related to each other and each being a different digit, and means including electromagnets associated with said spacers for moving said spacers into said space between said actuating means and said bolt.
