  • ABSTRACT A method for making steering or control strips for the automatic control of machines in which a design having one or more areas with periodically recurring distribution is transformed in raster-form on a pattern draft and in which the pattern draft is then scanned point-by-point in order to store the information in the form of scannable markings on the steering or control strips and to apparatus for use therewith.
  • PAIENTEDFEB 15 m2 sum 9 0F 6 Q BLUE abcdef
  • This invention relates to the field of steering or control strips for the automatic control of machines in which a design, having one or more areas with periodically recurring distribution is transformed in raster-form on a pattern draft and in which the pattern draft is then scanned to place the information on steering or control strips and to apparatuses for use therewith.
  • Steering or control strips produced in this fashion are suited for the control of many machines, especially for machines used in making pictures or patterns on or in flat-surfaced objects, such as paper, textile materials and the like.
  • the design is usually achieved by means of differences in the color or the type of stitches and/or relief, for example, straight or circular knitting machines, weaving machines, or machines for making mosaic pictures.
  • the steering or control strips may be, for example, perforated strips, films with transparent and nontransparent areas, or magnetic tapes which are scanned during the operation of the machine.
  • the scanning signals are then used in the necessary sequence which is generally derived from the arrangement of the information items stored on the steering or control strips for the purpose of controlling the various components of the machine.
  • the production of steering or control strips of this kind is described, for example, in British Pat. Nos. 1,160,897 and 1,170,947, and in French Pat. No. 1,572,966, to which reference is expressly made here.
  • This invention relates more particularly to an improved method for preparing steering or control strips for the automatic control or operation of machines whereby a design having one or more areas with periodically recurring form is transferred to raster-form on a pattern draft and in which the pattern shaft is scanned point-by-point in order to store the information on the steering or control strips, and to apparatuses for use therewith.
  • the invention starts with the realization that in the production of multicolored fabrics, mosaic pictures, and the like, the design frequently has a number of areas in which the colors, the kinds of stitches, or the like are repeated in a periodic sequence. This is true, for instance, when certain half-tones are produced in one row of stitches or stitch course and stitches of one kind periodically alternate with stitches of another kind. Also, in a mosaic picture, squares of one color periodically alternate with squares of another color.
  • this invention provides for the associate of each area of the pattern draft which has a periodically recurring distribution with only one color or brightness value on the pattern draft. Further, during the scanning of the pattern draft, each of these color or brightness values is electronically converted into a signal sequence which corresponds to the associated distribution of the design and is used for marking the steering or control strips.
  • the signal sequences are obtained, in accordance with one preferred version of this invention, through frequency division from the rectangular signals of the scanning frequency.
  • a regular square pattern according to a design, a square pattern which is illustrated in one color on the pattern draft, there can be used for each line of the pattern draft, one and the same signal sequence which is phase-shifted by from line-to-line during the line-by-line scanning of the pattern draft.
  • the advantage of the method according to this invention resides in the fact that in the production of the pattern draft it is necessary to draw only large single-colored surfaces which need not reveal that fine structure which later on appears on the finished article. This enables the saving of a considerable amount of time and work.
  • FIG. 1 illustrates a circular pattern on the surface of a fabric which is to be transferred to a steering strip according to this invention
  • FIG. 2 illustrates a pattern draft drawn in raster-form according to the pattern in FIG. 1;
  • FIG. 3 illustratesthe pattern draft drawn in raster-form according to the pattern in FIG. I, however, in contrast to FIG. 2, only one color is associated with each area having a periodically recurring pattern, according to this invention
  • FIG. 4a to 7b illustrate patterns with periodically recurring color or a stitch-type distribution and the signal sequences associated with each stitch row during the scanning of the pattern draft;
  • FIG. 8 shows a device for the transfer of the information items drawn on one pattern draft to a control film
  • FIG. 9 shows an electronic device for the recognition of the color or brightness values of the raster dots in the pattern draft
  • FIG. 10a shows a circuit diagram by means of which pattern-wise signal sequences are associated with the color recognition signals obtained with the device according to FIG. 9;
  • FIG. 10b illustrates the impulse forms of the impulses occuring in various places in the circuit diagram according to FIG. 10a.
  • one of the possible versions is a circular arrangement on the surface of a fabric.
  • a circular core 1 which is a single color, such as red is constituted on a white background.
  • concentric circular rings 3, 5, extend as transition zones to the white background. These rings 3, 5, are intended to create the impression of half-tones between red and white. If, for example, in the inside circular ring 3, there is selected a pattern consisting of alternating red or white stitches, both in a horizontal and in a vertical direction, then there is obtained a so-called one-one surface, which creates the effect of a tone in the middle between red and white if it is looked at from a sufficient distance.
  • Red and white stitches there is a sequence of red and white stitches. However, the number of white stitches on the average is greater. Red and white stitches, here likewise recur in a periodic sequence so that to the human eye there results a further gradation from the first ring 3 to the white surroundings.
  • limitation lines 7, 9, and 11 correspond to the circular limitation lines of core 1 and of circular rings 3 and 5 on the design.
  • the areas between the limitation lines on the other hand are drawn in a single color. More specifically, for examplethe core 1 is drawn in red, the first circular ring 3 is green, the second circular ring 5 is blue, and the surrounding is white. This considerably reduces the time required for the drawing of the pattern draft.
  • Another essential advantage consists in the fact that there can be almost no drawing mistakes because every area with periodically recurring color or stitch type pattern generally extends over a multitude of stitches.
  • plifier 38 to an impulse normalizer or pulse shaper as dis- A device for scanning the finished pattern draft and for making the steering or control strips has already been suggested in British Pat. Nos. 1,160,897 and 1,170,947, as well as in French Pat. No. 1,572,966.
  • the scanning device has the reference number 13 and the pattern draft to be scanned has the reference number 15.
  • the pattern draft consists of small squares, the raster dots A, B, C, D, and P, which are arranged parallel to the X- and Y-coordinates of a rectangular coordinate or grid system.
  • each square there is entered a color or brightness value corresponding to the color or the color distribution, respectively, a color or brightness value corresponding to the type of stitch or the stitch-type distribution on the design.
  • All raster dots which are located on a line parallel to the X-axis correspond to one course of stitches.
  • All raster dots located on a split or slot a, b, c, d, e, f, parallel to the Y-axis correspond to one stitch wale. If the part of the pattern draft 15, illustrated in FIG. 8, corresponds to an area of the design which is made up alternately of red and white stitches, then as indicated in connection with FIG. 3, all raster dots of the pattern draft would be drawn green.
  • the scanning device 13 In the scanning of the pattern draft, the scanning device 13 is moved parallel to the X-axis step-by-step over the pattern draft. so that one or more lines of the pattern draft are scanned simultaneously.
  • the scanning signals obtained are fed to an electronic system 19 via lines 17.
  • the color or brightness values corresponding to the individual raster dots are investigated, sorted, and then conducted onward to selected marking generators A1-24, which are arranged onthe circumference of a rotatable drum 21.
  • On the circumference of drum 21 there is located a steering or control film St, which does not slip or slide and which during the rotation of the drum is moved away via guide rollers 23 and 24 toward and over guide rollers 25 and 26.
  • the marking generators A1-24 are staggered toward each other in the direction of the drum axis so that the markings which are placed upon the film are distributed on different tracks.
  • the steering or control strips can, for example, be a film which is exposed by the marking generators.
  • the scanning device 13 contains a number of scanning heads 28 (FIG. 9) which are arranged next to each other, parallel to the Y-axis, and which scan each raster dot. If, as in the example according to FIG. 3, the pattern draft is drawn in four colors (red, green, blue, white), then there are associated with each scanning head three systems consisting of filters, optical lenses, photocells 30 and preamplifiers 32. The pattern draft is then exposed in terms of impulses with the scanning frequency, for example, c.p.s., and in accordance with the reflection capacity of the individual raster dots, flashes are directed at selected photocells of each scanning head.
  • the scanning frequency for example, c.p.s.
  • optical filters there can be made certain that there will be only one flash hitting one photocell of each scanning head, that is, if this scanning head just happens to be scanning a red, green, or blue raster dot, or that flashes will simultaneously hit all three photocells, if a white raster dot happens to be scanned at that particular moment. Further details of the scanning device have already been described in British Pat. No. 1,170,947.
  • each scanning head 28 of which only one cell is shown in FIG. 9 the light signals are converted into electrical signals.
  • the electrical signals are conducted via a line 34, a preamplifier 32, a shielded line 36, and a power amclosed in applicant's U.S. Pat. No. 3578976 issued May 18, 1971 40.
  • the impulse normalizer impulses with a constant location, length, and size are generated from the incoming signals, so that reliable recognition of the scanned color is possible and fluctuations'in the photo signals can be compensated.
  • the impulse normalizers which are connected with every photocell, give us information about the color of the raster dots. If all three impulse normalizers of a scanning head simultaneously give off one normalized or standardized impulse during one scanning step, this means that the associated scanning head has scanned a white raster dot.
  • each color recognition circuit reveals one output more than the pattern draft has colors.
  • the outputs 42A, 42B, 42C, and 42D, for the colors (hereafter called color outputs) of which there are four present in the example selected, can be connected with each marking impulse generator so that the impulses given off by the color recognition circuit will be directly steered toward these marking impulse generators.
  • the output 42A is, for example, associated with the color red
  • the output 423 isassociated with the color green
  • the output 42C is associated with the color blue
  • the output 42D is associated with the color white.
  • the fifth output 425 of the color recognition circuit 42 is connected with the exposure apparatus 44 for the marking impulse generators and gives off a release signal if there has been a flawless color recognition.
  • Each color recognition circuit has as essential components one AND-member and one OR-member (not shown).
  • the AND-member is thus connected with the three inputs and with the color output 42D'of the color recognition circuit in such a manner that,.in case of the simultaneous appearance of a normalized impulse at all three inputs, an impulse is given off only by the color output 42D of the color recognition circuit which is connected with the AND-member and so that the three other color outputs 42A-C are momentarily blocked because of the absence of a signal. This facilitates the recognition of white.
  • the recognition of the colors red, green, and blue there is an impulse at each one of the three other color outputs.
  • the OR-member is connected on the input side with the four color outputs 42A-D and on the output side, withthe fifth output 42E of the color recognition circuit 42. Consequently, this fifth output always gives off an impulse if there is one impulse only at one of the inputs of the OR-m ember (correspondingly, on one of the color outputs 42A-D).
  • the appearance of an impulse at the fifth output 42E of the color recognition circuit thus is a sign that a certain color has been definitely and clearly scanned by the scanning head.
  • the exposure apparatus 44 is controlled by means of output impulses from the fifth output 42E, that is, the shutter is released only if there has been a flawless color recognition.
  • the impulses appearing at the five outputs of the color recognition circuit in terms of their phase position and form correspond to the impulses given off by the impulse normalizers 40.
  • a marking is affixed during each scanning step on preselected tracks of the steering strip. If there is, for example, a four-color pattern on the pattern draft and if one line of the pattern draft is scanned per scanning step, then a total of four tracks of the steering or control strip is provided with markings.
  • the track 1 gets a marking if a red raster dot is scanned,; track 2 gets a marking if a green raster dot is scanned; track 3 gets a marking if a blue raster dot is scanned; and track 4 gets a marking if a white raster dot is scanned.
  • each track of the steering or control strip then controls each system of the machine.
  • the areas of the design corresponding to a periodic color or stitch-type pattern are drawn in one color on the pattern draft according to this invention.
  • a regular square pattern consisting of red and white stitches can, for example, be illustrated in green on the pattern draft.
  • the entire section of the pattern draft illustrated in FIG. 8 can likewise be drawn uniformly in green.
  • each color of the pattern draft there is associated with each color of the pattern draft, a signal sequence corresponding to the pattern that is present on a design or artistic drawing.
  • a red stitch can be illustrated by the presence of an electrical impulse (for example, the binary one) and the presence of a white stitch can be illustrated by the absence of an electrical impulse (for example, the binary zero).
  • an electrical impulse for example, the binary one
  • the presence of a white stitch can be illustrated by the absence of an electrical impulse (for example, the binary zero).
  • an impulse sequence whose follow up frequency is equal to the scanning frequency so that one impulse will appear during each scanning step.
  • FIG. 4a If, in accordance with FIG. 1, a regular square pattern is to be made in the inside circular ring 3, one would normally get a raster or screen pattern in accordance with FIG. 4a.
  • This checkerboard pattern is in accordance with this invention replaced by a uniform green coloring while the impulse sequences drawn in FIG. 4b, are associated with the green color.
  • each impulse corresponds to one red stitch and each interval between two impulses (binary zero) corresponds to one white stitch.
  • a red-white pattern in accordance with FIG. 4a were to be scanned with the help of the above-described, already previously proposed device, then there would be alternately marked a track set aside for red and a track set aside for white on the steering strip.
  • the pattern in FIG. 4a is drawn uniformly green, for example, on the pattern draft, it is necessary by means of an accessory circuit to see to it that the signal sequences according to FIG. 4b are associated with the color green, also by means of the impulses of these signal sequences the track set aside for red is marked on the steering strip while the intervals between two impulses cause the track of the steering strip set aside for white to be marked.
  • FIG. 10a it is possible to conduct the signals, given off by the color outputs 42A-D of thecolor recognition circuit according to FIG. 9, toward frequency dividers and AND- and OR- members.
  • the circuit according to FIG. 10a is suited for the marking of a steering strip according to a design which features a red core having in the form of a circular ring, (corresponding to the area formed by the two circular rings 3, 5 in FIG. 1), a red-white square pattern according to FIG. 4a and a white surrounding.
  • the color output 42A for red in the color recognition circuit 42 which is connected to one of the scanning heads 28, is connected with a line 46 while the color output 428 for green is connected with a line 48, and the color output 42D for white is connected with a line 50.
  • normalized impulses with a followup or sequence frequency which corresponds to the scanning frequency. They are conducted by means of an OR-member 01 and a line 52 to the marking generator of the track set aside for red. If white is recognized, then impulses develop in line 50 and with the scanning frequency. These impulses reach the marking generator of the track set aside for white by means of an OR- member 02 and a line 54.
  • the circuit described here keeps scanning green with the scanning head so long as alternating impulses are fed in by lines 52 and 54, so that the marking impulse generators, responsible for red and white, are alternately activated. Consequently, the tracks of the steering or control strip, which correspond to red and white, are marked alternately, so that, we get the same marking sequence on the steering or control strip as if the red-white checkerboard pattern had been applied upon the pattern draft, dot for dot, as hitherto customary, and as if the old device had been used.
  • FIG. 10b The impulse forms which develop at the various places in the circuit diagram according to FIG. 10a, are illustrated in FIG. 10b.
  • the two OR-members 01 and 02 prevent impulses from being conducted into the lines 52, respectively, 54. Also,
  • the switching diagram according to FIG. 10a is suited for making the patterns illustrated in FIGS. 40 and a, as seen from the associated signal sequences in accordance with FIGS. 4b and 5b, all of which are identical. If the pattern draft is scanned with only one scanning head 28, then to make the pattern according to FIG. 40 one must make sure that a phaseshift of the associated signal sequence is performed by 180 as I we go from line to line in the pattern draft. If the pattern according to FIG. 5a is to be transferred, then this phase-shift is not necessary.

Without such phaseshifts there is obtained only make the pattern according to FIG. 5b.
  • FIG. 6a which is characterized by the impulse forms shown in FIG. 6b.

  • the impulse sequences illustrated in FIG. 7b are associated with such a pattern, which approximately corresponds to the pattern of the circular ring 5 in FIG. 1.
  • the invention is not confined to the design versions described here. Instead, it can be advantageously used whenever one wants to transfer designs with periodically recurring color or stitch-type distribution upon a steering strip. It is possible here that the electronic expenditure for the steering strip marking device might increase considerably. This increased expenditure however is in no ratio whatsoever to the time savings and to the manpower savings for making the pattern draft. Besides, this invention is not confined to the described device for the scanning of the pattern draft and for the marking of the steering strip.
  • the structure of the device instead depends on how many systems the machine to be controlled will have, and therefore, how many tracks the steering strip will have, how many colors are drawn on the pattern draft and in what way the design is patterned. The structure of the device therefore depends extensively on the individual case so that one in the art can find the most favorable solution in each particular case with the help of the known circuit elements.
