Description

The information display device of loom

Technical field

The present invention relates to a kind of loom, particularly possess at least warp thread deflector roll as the multiple parts had an impact to the path of warp thread and the heald that is installed on respectively on multi-disc heald frame, the warp thread of drawing from warp beam knits front to being diverted by described warp thread deflector roll court, is directed to the information display device of the loom before knitting after the heald of the heald frame through the correspondence in described multi-disc heald frame.

Background technology

As shown in Figure 1, in general loom, warp thread 101 is sent from the warp beam 102 being wound with warp thread 101, is wrapping with for guiding multiple deflector rolls 103 of warp thread 101 (to comprise the jockey pulley 105 being detected warp tension by tension pick-up 104.Identical below.) on, after 106 directions are diverted before knitting, via as the menopause tablet device 107 etc. of cracked ends checkout gear detecting cracked ends, and be directed to through the heald 109 of the heald frame 108 of multi-disc arrangement and knit front 106.By move up and down (harness motion) of heald frame 108 (heald 109), opening is formed by many warp thread 101, being beaten towards knitting front 106 by reed 111 by the weft yarn 110 of wefting insertion to this open interior, being formed weave cotton cloth 112 by being woven into warp thread 101.Weaving cotton cloth of weaving like this 112 is taken up on work beam 114 through taking winding up roller 113 etc.

Lean on most the deflector roll of heald 109 side (hereinafter referred to as " warp thread deflector roll " from being positioned at multiple deflector roll 103.In the example shown in Fig. 1, jockey pulley 105 is equivalent to " warp thread deflector roll ".) (following to the path of the warp thread 101 knitted between front 106, in the application, this path is only called in " path of warp thread "), be generally carry out before starting to weave weave the preparatory stage, adjusted according to weaving condition (such as: the kind of warp thread 101 and weft yarn 110, the setting tension force etc. of warp thread 101).Path due to warp thread is changed by the harness motion of warp thread 101, therefore, during path, opening as required for warp thread when remaining silent warp thread path in either or both adjust.

Path due to warp thread is present on the path of warp thread according to the heald 109 etc. of mentioned strain roller 105 and menopause tablet device 107, heald frame 108, the path of the warp thread multiple parts had an impact and the position relationship knitting front 106 are decided, therefore, above-mentioned adjustment is undertaken by the position of at least one adjusted in these multiple parts had an impact to the path of warp thread.Specifically, be by changing the position of jockey pulley 105, or adjustment is carried out for the opening amount making heald 109 carry out the heald frame 108 of harness motion.

As the prior art relevant to such adjustment, there is technology disclosed in a kind of such as patent document 1.In this patent document 1, by adjusting the path of warp thread with the height and position of adjustment screw adjustment support arm, described support arm is for supporting the deflector roll as the parts had an impact to the path of warp thread.

Prior art document

Patent document

Patent document 1: Japanese Unexamined Patent Publication 6-10240 publication

But, in order to adjust the path of warp thread, when the position that operator adopts device disclosed in patent document 1 etc. to adjust the parts that the path of warp thread has an impact, in the past, only have and actually after the adjustment carry out test weaving, and could judge that whether this adjustment is suitable according to whether carrying out weaving under the state of hope, and for adjustment amount being set as how many degree, present situation is experience with operator and sensation.Namely, as to the state in path of weaving the warp thread had an impact, can exemplify such as: the opening angle of warp thread when the path of warp thread and opening, but for these paths and opening angle, even if make loom crawl behind the position of the described parts of adjustment, warp thread is made to become the state of opening, but in the visual scope that can hold, whether operator wants this state of paying attention suitably still to have any problem for weaving, so present situation only has actually to carry out test weaving and could judge.Therefore, in adjustment operation in the past, first, based on operator experience and feel initially to adjust, temporarily carry out test weaving in this condition, judge whether to need further adjustment, again adjust when needs adjust further, with such adjustment repeatedly, adjustment is operated not only time-consuming but also require great effort.

In addition, for as to the path of warp thread of path status of weaving the warp thread had an impact, this path is the longest when opening, and the tension force of warp thread becomes maximum state simultaneously.Therefore, as the result in path that have adjusted warp thread, if the overtension of warp thread during opening, then when weaving, the tension force of warp thread will become the state of overtension, cause quality of weaving cotton cloth and will reduce, also can cause cracked ends continually in some cases.But, for the tension state of this warp thread, weaving in the preparatory stage, even if loom is set in the state that warp thread is opening, still having any problem with visual assurance, judging whether it is applicable to still needing to carry out test weaving as above.

For the opening angle of warp thread during opening, when warp thread is the yarn of the easy fluffings such as short fibre yarn, the path of the preferred adjustment each warp thread opening angle of warp thread (during the maximum open), the path of each warp thread during maximum open is from the side made to be irregular state, to disperse up and down to a certain degree, to become the state of scattering.Its reason is, setting makes open curve have equal-diameter part, when keeping the open state of warp thread when the maximum open in weaving, if the path of each warp thread is too neat, then the fluffing of each warp thread will be wound around mutually, cause opening bad, probably also can cause cracked ends in some cases.But if the degree of the dispersion of each warp thread (hereinafter referred to as " degree of scatter ") is set to excessive, then the tension state of the warp thread of each heald frame can produce bigger difference, on the contrary may to weaving generation bad influence.Therefore, for the degree of scatter of this warp thread, in fact need with the visual degree not easily judged, the path of each warp thread to be disperseed.Therefore, same as described above, weaving in the preparatory stage, even if loom to be located at the state that warp thread is opening, still visually can not to judge whether it is applicable to, and need test weaving as above.

As mentioned above, only lean on the experience of operator without any benchmark and feel that the regulated efficiency in the path of carrying out warp thread is low, during the path of warp thread particularly when adjusting opening, while consider the tension force of warp thread, while make the path of warp thread disperse, this is for the few operator of experience being a very difficult operation.

Summary of the invention

Problem of the present invention, be the display such as numerical information in the path about warp thread of the adjustment operation benchmark in the path making to become warp thread over the display, the opening angle etc. of warp thread when enabling operator correctly hold the path of warp thread and the opening of the state in the path representing warp thread, further, enable operator easily and carry out at short notice the path of warp thread adjustment operation.

For solving above-mentioned problem, the information display device of loom of the present invention is formed as follows.Namely, the information display device of loom of the present invention is premised on following loom: possess at least warp thread deflector roll as the multiple parts had an impact to the path of warp thread and the heald that is installed on respectively on multi-disc heald frame, the warp thread of drawing from warp beam knits front to being diverted by described warp thread deflector roll court, after the heald through heald frame corresponding in described multi-disc heald frame, be directed to before knitting, its technical essential is to comprise setting device, and it is set with the positional information of the configuration about described multiple parts; Arithmetic unit, it obtains the numerical information in the path about warp thread based on described positional information by computing; Display unit, it is by the described numerical information by described arithmetic unit computing and/or be presented on picture based on the line chart of described numerical information.

Here, " the multiple parts to the path of warp thread has an impact " refer to, (following at the parts of the position of above-below direction restriction warp thread, " the multiple parts to the path of warp thread has an impact " are also referred to as " limiting part "), be not limited in described warp thread deflector roll, the heald of the heald frame of shedding motion, also comprise such as: when being provided with cracked ends checkout gear (menopause tablet device) in loom, comprise the parts of the position of the restriction warp thread that cracked ends checkout gear possesses, when being provided with other limiting parts in loom, also these limiting parts are comprised.

" warp thread deflector roll " refers to, is arranged in the deflector roll leaning on heald side most of the multiple deflector rolls guiding warp thread, also comprises the jockey pulley detecting warp tension in described multiple deflector roll.

" configurations of multiple parts " refer to, about the horizontal direction (fore-and-aft direction) of these parts and the position of vertical (above-below direction), reference position (datum level) distance to each limiting part from regulation is set, as positional information in setting device.In addition, the position of each parts is not the position of the position of finger entirety, the device entirety being provided with parts, and refers to such as: if limiting part is heald, be then a part for heald, the position of the harness eye of the part of passing as warp thread; If limiting part is possess the elliptical tube on menopause tablet device, then it is position that elliptical tube contacts with warp thread partly.In addition, the harness eye of heald refers to and is located on heald, makes the through hole that warp thread passes.When the parts along with action as heald, as positional information, also the position of arbitrary multiple Spindle rotation angle degree (degree in crank angle) can be set, such as: during maximum open with warp thread, time of remaining silent etc. corresponding position, only can also set the position of specific degree in crank angle.

The application's said " warp thread " is strictly " warp thread piece ".The many warp thread of drawing from warp beam are divided into sheet by each heald frame, and the warp thread group of the sheet split, i.e. warp thread piece are through the heald of corresponding heald frame.Here, the warp thread that the warp thread piece through the heald of same heald frame comprises advances along same paths, therefore, in the present invention, and the path of warp thread and the path synonym of warp thread piece.

Also described arithmetic unit can be made based on described positional information, and according to the distance from the horizontal direction before knitting to heald of each heald frame with from the distance of knitting the vertical of front side datum level to the harness eye of this heald during warp thread maximum open as the horizontal plane before knitting described in passing through, as described numerical information, obtain by each heald frame and be positioned at than each heald frame by the relevant numerical value of the degree of scatter of each warp thread of knitting front side.

Here, " to being positioned at than each heald frame by the relevant numerical value of the degree of scatter of each warp thread of knitting front side " refers to, such as: than each heald frame, by knitting front side, (be the path of each warp thread from the side, the heald passed than this warp thread is by front side of knitting.Identical below.), can be (reference Fig. 8) such as the angles that formed with parallel imaginary vertical guide relative to heald of angle (with reference to Fig. 5 (a)), each warp thread that datum level (horizontal plane) that each warp thread specifies relatively is formed.Also can be heald frame and before knitting between the position (with reference to Fig. 9) of above-below direction that intersects of the ad-hoc location imaginary plane, each warp thread that extend at above-below direction.

Also described arithmetic unit can be made based on described positional information, and according to each heald frame from heald to relative this heald with counter knit the path of the immediate position limitation warp thread in front side counter knit horizontal direction the limiting unit of front side distance and as by described counter knit the horizontal plane of front side limiting unit counter knit on front side of the distance of the vertical of datum level to the harness eye of this heald during warp thread maximum open, as described numerical information, obtain by each heald frame and be positioned at than each heald frame by the relevant numerical value of the anti-degree of scatter of each warp thread of knitting front side.

Here, " counter knit front side limiting unit " refers to, is knitting front side than each heald frame (path of each warp thread from the side, the heald passed than this warp thread leans on warp thread deflector roll side by counter.Identical below.), relative heald, in a part for the limiting part in the path of immediate position limitation warp thread, is that this limiting part contacts with warp thread the last contact point of the warp thread direction of advance in part.

In addition, than heald frame by knit front side, knit between front and the heald as limiting part and there are not other limiting parts, but knitting front side than heald frame by counter, other limiting parts are provided with sometimes, such as: the limiting part etc. that yarn limiter tube, cracked ends checkout gear possess between heald frame and the warp thread deflector roll as limiting part.As an example, cracked ends checkout gear is provided with between heald frame and warp thread deflector roll, when the opening of warp thread, in the confined situation of a part of the limiting part that the path of warp thread is possessed by cracked ends checkout gear, a part for this limiting part becomes counter and knits front side limiting unit.On the other hand, when not being provided with other limiting parts between warp thread deflector roll and heald, a part for warp thread deflector roll becomes counter and knits front side limiting unit.

And, during the opening of warp thread, warp thread be divided into be brought towards upside aperture position and be brought towards open lower side position, there is the limiting part only limiting the path of its any one party.Such as: when cracked ends checkout gear is menopause tablet device, the elliptical tube as the limiting part of menopause tablet device only limits the path of the warp thread being brought towards open lower side position, does not limit the path of the warp thread being brought towards upside aperture position.Therefore, when only there is menopause tablet device between heald frame and warp thread deflector roll (such as: with reference to Fig. 7), it is a part for elliptical tube that warp thread in open lower side position counter knits front side limiting unit, knits the counter of warp thread of upside aperture position the part that front side limiting unit is warp thread deflector roll.In this situation, anti-front side limiting unit of knitting exists 2, and, also there are 2 by these anti-anti-front side datum levels of knitting knitting front side limiting unit.

" to being positioned at than each heald frame by the relevant numerical value of the anti-degree of scatter of each warp thread of knitting front side " refers to, such as: knitting front side than each heald frame by counter, can be (with reference to Fig. 8) such as the angles that formed with parallel imaginary vertical guide relative to heald of angle (with reference to Fig. 5 (b)), each warp thread that datum level (horizontal plane) that each warp thread specifies relatively is formed.Also can be in heald frame and anti-position (reference Fig. 9) of knitting imaginary plane that the ad-hoc location between the limiting unit of front side extends at above-below direction and the above-below direction that each warp thread intersects.

Make described arithmetic unit based on described positional information, according to the following information about distance, as described numerical information, from the path of warp thread deflector roll to before knitting when obtaining the maximum open of each warp thread by each heald frame.

The distance from the horizontal direction before knitting to heald of each heald frame

Each heald frame from described distance of knitting the front side vertical of datum level to the harness eye of heald during warp thread maximum open

Each heald frame from heald to the described anti-distance of horizontal direction of knitting the limiting unit of front side

Each heald frame from described anti-distance of knitting the front side vertical of datum level to the harness eye of heald during warp thread maximum open

From described anti-distance of knitting the horizontal direction of front side limiting unit to the warp thread limiting unit of warp thread deflector roll

Side datum level is sent to described anti-distance of knitting vertical front side limiting unit (counter knit front side datum level) from the horizontal plane as the warp thread limiting unit by warp thread deflector roll

Here, " the warp thread limiting unit of warp thread deflector roll " refers to, warp thread deflector roll contacts with warp thread the last contact point of direction of advance of the warp thread in part.

In addition, as mentioned above, when not being provided with other limiting parts between warp thread deflector roll and heald, the warp thread limiting unit of warp thread deflector roll knits front side limiting unit for counter, therefore, " from described anti-distance of knitting the front side horizontal direction of limiting unit to the warp thread limiting unit of warp thread deflector roll ", and " from the horizontal plane as the warp thread limiting unit by warp thread deflector roll send side datum level to described anti-distance of knitting vertical front side limiting unit (counter knit front side datum level) " is zero.

Identical with the height and position of the vertical of the warp thread limiting unit of warp thread deflector roll before knitting, and Warp line (be the line linking the warp thread limiting unit of knitting front and warp thread deflector roll, identical below.) for level when, knit front side datum level and send side datum level all consistent with Warp line (such as reference Fig. 2).But different looms, is set to the position of the warp thread limiting unit of warp thread deflector roll than knitting front high position sometimes, and Warp line is made to become the state (such as with reference to Fig. 7) of inclination.In this situation, knit front side datum level and to send side datum level all inconsistent with Warp line, sending side datum level is in the high position of vertical than datum level on front side of knitting.

Also described display unit can be made the described numerical information about more than at least 2 heald frames and/or be simultaneously displayed on a picture based on the line chart of described numerical information.

The present invention is based on the positional information of the configuration about the multiple parts had an impact to the path of warp thread, obtain the numerical information in the path about warp thread, and using the described numerical information obtained as described numerical information and/or be presented on the picture of display unit based on the line chart of described numerical information, therefore, operator, can using visual the state being difficult to the path of the woven warp thread of impact held in the past as paying attentions such as numerical informations by referring to this display.With this, could judge whether the state in the path of warp thread is suitable for weaving relative to must carry out test weaving in the past, the present invention by will display numerical information on the display apparatus etc. as benchmark, test weaving need not be carried out and just can judge whether the state in the path of warp thread is suitable for weaving.When mechanicalness adjustment has been carried out to the position of the parts that the path of warp thread has an impact, as long as reset the positional information of the configuration about these parts, the state of the pathway of the warp thread after adjustment is just presented on the picture of display unit as numerical information etc., therefore, test weaving just need not can carry out the initial decision whether this adjustment be applicable to, can easily and carry out the adjustment operation in the path of warp thread at short notice.

Numerical information is turned to by the status values in the path by warp thread, as long as this numerical information is associated data base system with the problem etc. of woven assessment carried out in this condition and generation, just can more easily and suitably carry out at the route adjust weaving the warp thread that the preparatory stage carries out.

As the numerical information in the path about warp thread, obtain by each heald frame and be positioned at than each heald frame by the relevant numerical value of the degree of scatter of each warp thread of knitting front side, it can be used as numerical information and/or be presented on the picture of display unit based on the line chart of numerical information, therefore, operator by referring to this display, can using in the past visual be difficult to hold be positioned at than each heald frame by knitting the degree of scatter of each warp thread of front side as paying attentions such as numerical informations.With this, particularly when warp thread uses short fibre yarn etc. that the yarn of fluffing easily occurs, operator can using described numerical information etc. as benchmark, in the degree, the i.e. visual degree not easily differentiated that do not make the tension state of the warp thread of each heald frame produce bigger difference, the path of each warp thread is disperseed, can not to weaving generation bad influence, the path because of each warp thread can be prevented too neat and cause the fluffing of each warp thread to be wound around mutually, the bad and cracked ends of opening.When mechanicalness adjustment has been carried out in the position of the parts had an impact to the path of warp thread, as long as reset the positional information of the configuration about these parts, the degree of scatter of each warp thread after adjustment will be presented on the picture of display unit as numerical information etc., therefore, test weaving just need not can carry out the initial decision whether this adjustment be applicable to, can easily and carry out the adjustment operation of the degree of scatter of warp thread at short notice.

As the numerical information in the path about warp thread, obtain by each heald frame and be positioned at than each heald frame by the relevant numerical value of the anti-degree of scatter of each warp thread of knitting front side, it can be used as numerical information and/or be presented on the picture of display unit based on the line chart of numerical information, therefore, operator by referring to this display, can using in the past visual be difficult to hold to be positioned at than each heald frame by the degree of scatter of each warp thread on front side of counter knitting as paying attentions such as numerical informations.With this, effect same as described above can be obtained.

As the numerical information in the path about warp thread, from the path of warp thread deflector roll to before knitting when obtaining the maximum open of each warp thread by each heald frame, it can be used as numerical information and/or be presented on the picture of display unit based on the line chart of numerical information, therefore, operator, can using visual the path being difficult to the warp thread held in the past as paying attentions such as numerical informations by referring to this display.With this, using the display numerical information about path on the display apparatus etc. as benchmark, can need not carry out test weaving and just can judge whether the path of warp thread is suitable for weaving.When mechanicalness adjustment has been carried out in the position of the parts had an impact to the path of warp thread, as long as reset the positional information of the configuration about these parts, the path of the warp thread after adjustment will be presented on the picture of display unit as numerical information etc., therefore, test weaving just need not can carry out the initial decision whether this adjustment be applicable to, can easily and carry out the adjustment operation of the path of warp thread at short notice.

[supplementary notes about the positional information of the heald of input heald frame]

In addition, when inputting the positional information of heald 15 of heald frame, considering that the situation of the above-below direction displacement of warp thread 11 in harness eye 24 is useful for obtaining correct warp path numerical value, being described in detail below.

Fig. 6 (a) is the front view of the heald 15 as limiting part.The harness eye 24 of the through hole passed as warp thread 11 is formed in the substantial middle of heald 15.Harness eye 24 is formed as elongated hole-shape, and the lengthwise dimension of its heald 15 is larger than the diameter of warp thread 11.Therefore, through the warp thread 11 of harness eye 24 become can in harness eye 24 vertical displacement state to a certain degree.Further, the upper and lower side of heald 15 is arranged on not shown heald frame by heald support component 25.In more detail, the upper and lower side of heald 15 is formed with the otch 26 of elongated hole-shape, and this otch 26, by fixedly hanging on the heald support component 25 of heald frame, is supported on heald frame with this.Further, the lengthwise dimension of heald support component 25 is only smaller than the lengthwise dimension of otch 26.Therefore, heald 15 is heald frame relatively, has gap 27 to a certain degree and supported at above-below direction.

The position of warp thread 11 position of harness eye 24 and heald 15 heald support component 25 (heald frame) relatively relatively when Fig. 6 (b) represents side opening upward.Upward during side opening, warp thread 11 to become in harness eye 24 displacement downward and its path in the confined state in the lower end of harness eye 24.On the other hand, Fig. 6 (c) represents towards warp thread during open lower side 11 position of harness eye 24 and the position of the relative heald support component 25 of heald 15 relatively.During towards open lower side, warp thread 11 to become in harness eye 24 displacement upward and its path in the confined state in the upper end of harness eye 24.Heald support component 25 becomes the state of the below being displaced to otch 26.

Like this, at upside aperture position according to heald frame, or in open lower side position, the warp thread 11 relatively position of harness eye 24 and the position of the relative heald frame of heald 15 changes, therefore, when inputting the positional information as the vertical of the heald 15 of limiting part, preferably consider these changes.

When particularly inputting the positional information of the vertical of heald 15 with opening amount (i.e. the displacement of heald frame), as mentioned above, the positional information x of the vertical of heald 15, y is equivalent to the vertical distance (hole) center from Warp line WL to harness eye 24, but when hope inputs more accurate information, preferably consider the situation of the above-below direction displacement of warp thread 11 in harness eye 24.

Such as: as the positional information of the vertical of the heald of limiting part,

X: from knitting front side datum level (Warp line WL) to vertical distance during warp thread maximum open the harness eye 24 of the heald 15 of upside aperture position

Y: from knit front side datum level (Warp line WL) to vertical distance during warp thread maximum open when the harness eye 24 of the heald 15 of open lower side position when inputting above-mentioned numerical value with opening amount, can in advance the size of the length direction of harness eye 24 be set in setting device 17, for positional information x, inputted upper shed amount is carried out and revises, deduct 1/2 of the lengthwise dimension of harness eye 24; For positional information y, inputted under shed amount is carried out and revises, deduct 1/2 of the lengthwise dimension of harness eye 24.But, the error of the warp path numerical information caused because of the above-below direction displacement of warp thread 11 in harness eye 24 is less, also can omit above-mentioned correction.

And, heald frame when open lower side position, the position of heald 15 (i.e. harness eye 24) compared with under shed amount, only with the amount displacement upward in the relative gap 27 of heald frame of heald 15.Therefore, when with opening amount input position information y, also can in advance the gap value of relative for heald 15 heald frame be set in setting device 17, positional information y be carried out and revises, deduct gap value.But, in this situation, when the error of the warp path numerical information that the gap 27 because of the relative heald frame of heald 15 causes is less, also can omit above-mentioned correction.

Then, based on Fig. 5, the warp path numerical information performed by arithmetic unit 20, the i.e. calculating of yarn angular aperture and path are described in detail.In addition, in Fig. 5, to illustrate for typical example in the state of upside aperture position closest to the heald 15 of heald frame, i.e. the 1st frame of knitting front 16 in 8 heald frames.Further, the operation method used to calculate yarn angular aperture and path described below is only an example, and other computings can obtain yarn angular aperture and path too.

Above, for the specific embodiment of information display device of the present invention, describe 2 embodiments, but the present invention is not limited in these embodiments, also can does various distortion.

[reference position etc. for the positional information of limiting part]

In described embodiment, the positional information of the horizontal direction of each limiting part with before knitting for benchmark and setting, but also can set other specific reference positions, and the distance of setting from this position to each limiting part.But, in this situation, for the position before knitting, also need to set the distance from this reference position to before knitting.Equally, also can using each limiting part the positional information of vertical datum level as knit front side datum level beyond horizontal plane, such as: send side datum level.And also can set like this as the positional information of the heald of heald frame, such as: in the horizontal direction, set from the anti-distance of front side limiting unit to the center of the harness eye of the heald of each heald frame of knitting; In vertical, set and knit the distance of front side datum level to the harness eye of the heald of heald frame during the maximum open of warp thread from counter, etc.

[the yarn angular aperture for as the numerical value relevant to the degree of scatter of warp thread]

In described embodiment, as the numerical value relevant to the degree of scatter of warp thread, obtain the angle that each warp thread is formed with the datum level of corresponding level when maximum open, namely the angle that on front side of obtaining warp thread and knit before frame, datum level is formed, warp thread and the anti-angle of knitting front side datum level and being formed is obtained after frame, but also can change into and obtain each warp thread when maximum open, the angle formed with the imaginary vertical guide (hereinafter referred to as " imaginary plumb datum face ") of length direction (vertical) of the heald being parallel to heald frame.

Such as: as shown in Fig. 8 (a), imaginary plumb datum face α _n(heald frame No.n=1,2 ...) also can be set as at the center of each heald frame by harness eye 24.In this situation, for the warp thread 11 of the n-th frame, the warp thread 11 before frame and the warp thread 11 after frame, imaginary plumb datum face becomes general.

Further, as shown in Fig. 8 (b), it is general that imaginary vertical guide also can be set on all heald frames, before frame with after frame, set 1 respectively.In this situation, for the imaginary plumb datum face β of the warp thread 11 before frame _fbe set in the heald frame (the 1st frame) before closest knitting and knit between front 16, for the imaginary plumb datum face β of the warp thread 11 after frame _rbe set in distance knit front 16 heald frames (the 8th frame of the situation of described embodiment) farthest and instead to knit between the limiting unit 14a of front side.

[other numerical value for relevant to the degree of scatter of warp thread]

As the numerical value relevant to the degree of scatter of warp thread, obtain the datum level angle that formed of each warp thread 11 relative to regulation in described embodiment, but also can change into obtain be set in than heald frame by reference position (knit front 16, counter knit front side limiting unit 14a) side imaginary plane (such as: the imaginary plumb datum face β of Fig. 8 (b) _f, β _r) height and position of the above-below direction of position that intersects with each warp thread 11, namely from datum level (knitting front side datum level) the distance H to the position of intersection of level _fTn, H _rTndeng (Fig. 9 (a)).Here, in Fig. 9 (a), knit front side datum level consistent with Warp line WL.

In addition, the imaginary plane in this situation extends at above-below direction, and about the width of heald frame, is set as extending abreast with heald frame.Now, about the warp thread piece of the n-th frame, the height being contained in each position that many warp thread in this warp thread piece intersect with imaginary plane is phase co-altitude.Therefore, about width, as long as the plane extended in parallel with heald frame, be not limited only to the plane extended in vertical about above-below direction shown in Fig. 9 (a), also can be as shown in Fig. 9 (b), Warp opening from the side, by the plane γ be inclined relative to horizontal _f, γ _ras imaginary plane.Further, the situation of Fig. 9 (b) also can be identical with the situation of Fig. 9 (a), obtains the distance H from the datum level of level _fTn, H _rTn, but also as shown in the figure, the distance H from the datum level of the upper and lower bearing of trend along imaginary plane can be obtained _fTn', H _rTn'.

[relation etc. for the warp path numerical information obtained and open state]

For the warp path numerical information obtained, when being not limited in maximum open, also can obtain the warp path numerical information of other specific Spindle rotation angle degree (comprising multiple situation).But, in this situation, need first the setting of the positional information of each limiting part (parts to the path of warp thread has an impact) of the necessity in this specific Spindle rotation angle degree to be stored in storage part 19.Further, in described embodiment, as warp path numerical information, be yarn angular aperture and the path of each warp thread when obtaining maximum open, but be not limited in and obtain these both, the present invention also comprises any one party only obtained wherein.

[for display about the yarn angular aperture as calculated warp path numerical information]

In described embodiment, display value information and both the line charts based on numerical information, but also can only show wherein any one party.
