Background technology
That has implemented that cloth decoration rib (pin tuck) makes makes thing (cloth) owing to have good retractility and unique ornamental, so its demand is increased day by day.
By make thing (cloth) in turnover after, carry out and relative stitching partly along folding portion, can form the cloth decoration rib.
In addition, at first form the cloth decoration rib, then this is made thing (cloth) and form fixing cloth decoration prismatic shape, remove suture by seam-ripping again, can form semi-permanent pleated cloth decoration rib through Overheating Treatment by basting suture.If implement such cloth decoration rib in large quantities, then can constitute basic material with good retractility, and, if be used to decorate surface, then can embody a kind of material sense of uniqueness at bed clothes etc., therefore, won people's favor.
Under the situation of carrying out basting suture, how to remove this line that stretches tight easily, be generally and be the important topic in the production process.
In addition, under the situation that the cloth decoration rib is used as decoration, problem may appear on the free degree of its uniformity and design etc., and therefore, people wish to have a kind of technical ability that does not rely on skilled operators just can positively sew the Sewing machines of cloth decoration rib evenly attractive in appearance.
In addition, people need a kind of can be simply and sew with keeping its uniformity and not only comprise straight line, but also comprise the Sewing machines of curvilinear cloth decoration rib, be used to expand the free degree of design.
In addition, people there is also a desire for that a kind of the operator can be by the visual Sewing machines of confirming the stitch state in the process of making operation with Sewing machines.
In the past, in order to make by the cloth decoration rib that thing (cloth) is constituted of making that is folded into U word shape, or the Sewing machines that uses the cloth decoration loophole system that forms by the transformation of existing sawtooth stitch sewing machine to use, or use existing sewing machine for covering chain stitch.Under these circumstances, adopt following method of sewing to make usually.
(example 1 in the past)
The situation of using the Sewing machines that is formed by the transformation of existing sawtooth stitch sewing machine (as example 1 in the past) is described with reference to Figure 11 (a).
Shown in Figure 11 (a), under the situation of using the Sewing machines formed by the transformation of existing sawtooth stitch sewing machine, the 2 pin fixed parts 6 that pin is used of lower end configuration at the needle bar 1 of existing sawtooth stitch sewing machine are provided with pin 2a and pin 2b by pin fixed part 6.On pin 2a and pin 2b, pass upper thread (not shown) respectively.On needle plate 4, form projection 7.Make the distortion that thing (cloth) 3 forms inverted u-shaped thereby can make.By changing the height of this projection 7, can adjust the shape of cloth decoration rib.
Under the state that stops balancing point of sawtooth stitch sewing machine, use.When after making thing (cloth) 3 and being placed on the Sewing machines, make the cloth decoration prismatic shape of projection 7 formation the fall U word shapes of thing (cloth) 3 along needle plate 4 above.When Sewing machines turns round, about two pin 2a, 2b break-through simultaneously make thing (cloth) 3, the bottom line that is through upper thread and single rotating shuttle 5 on left and right sides pin 2a, the 2b forms hook company.Making formation cloth decoration rib on the thing (cloth) 3 in this wise.
(example 2 in the past)
Under the situation of using existing single needle formula sewing machine for covering chain stitch (not carrying out balancing point), shown in Figure 11 (b), making thing (cloth) 3 doublings, pin 2 is sewed up along the position of cloth decoration rib, after finishing stitching, by guaranteeing the shape of cloth decoration rib making thing (cloth) 3 expansion.
But, in the example in the past of the Sewing machines that above use is formed by the transformation of existing sawtooth stitch sewing machine, the problem that the person of existence is following.
Its 1: in example 1 in the past because 2 upper threads that pass left and right sides pin 2a, 2b carry out hook in sawtooth is made the rotating shuttle 5 of usefulness connect, make the upper thread of rotating shuttle about must be nested, but the spur that makes rotating shuttle 5 come nested its at interval only quite 2 upper threads at the interval of left and right sides pin 2a, 2b be suitable difficulty, require very harsh problem so exist the regularization condition that hook to left and right sides line connects spurs such as time.
Its 2: in example 1 in the past, behind the spur of having adjusted rotating shuttle 5, since left and right sides upper thread take out the line asynchronism(-nization) in the rotating shuttle 5, so form the uneven state of making, and hooked by the spur of rotating shuttle 5 from left and right sides upper thread the time be carved into moment that left and right sides upper thread extracts out in the rotating shuttle 5 during in, left and right sides upper thread forms the phase mutual interference in rotating shuttle 5, therefore, caused the line states problem of unstable.
Its 3: in example 1 in the past, although owing to be to be in the unsettled state of making, the tubercle point of line all is below making thing (cloth) 3 when making, and can not be when making makes the problem that state etc. is confirmed to unsettled so exist.That is, poor to the direct observation of making stitch.
Its 4: in example 1 in the past, exist the problem of unstable shapes such as in cloth decoration prismatic shape, forming seam wrinkle, distortion.
Trace it to its cause, can think and have following 3 etc., 1. partly give prominence on make thing (cloth) 3 owing to inverted u-shaped cloth decoration rib, directly do not contact with the work feed tooth, be configured in position away from the work feed tooth, so carrying out with the interval of making stitch when mobile, work feed power is not easy to be conducted to cloth decoration rib part; 2. be formed on the cloth decoration rib part of making the inverted u-shaped above the thing (cloth) 3 and form with presser feet (not shown) and left and right sides pin 2a, 2b and contact, be subject to its interference, the masterpiece of Xing Chenging is used in overslaugh and makes on the direction of conveying of thing (cloth) 3 therefrom; 3. since the cloth decoration rib of inverted u-shaped partly be formed on make thing (cloth) 3 above, because of being subjected to the influence of gravity, form unsettled shape easily.
In order to correct into the shape of cloth decoration rib, must make thing (cloth) 3 with two handgrips by the operator and pull to cloth feeding direction and cautiously advance, the uniformity of goods is subjected to the restriction of operator's qualification.Then more require the operator to grasp skilled operative skill for curvilinear cloth decoration rib etc.
Its 5: in example 1 in the past, exist the problem that can not carry out a kind of seam-ripping basting suture easy and simple to handle.Sewing machines under general situation, the relative tension force of upper thread, the tension force of bottom line very a little less than, also be difficult to accomplish and make linearly the making of bottom line even strengthen the tension force of bottom line.Therefore, owing to constituted 2 upper threads on straight line, bottom line is jagged stitch, so any single line all is not easy to be stretched out in example 1 in the past.
On the other hand, use the example in the past 2 of existing sewing machine for covering chain stitch to exist following problem.Promptly, use making of sewing machine for covering chain stitch owing to be to carry out suitable turnover in the position of cloth decoration rib making thing (cloth) 3, the operator is by manual operation, sew up while carrying folding portion, therefore, exist operability and productivity is poor, to the big problem of dependence face of practician's skill level, and, exist the problem that is difficult to evenly make in situation of the cloth decoration rib of making multiple row (2) etc.
In addition, in example 2 in the past, owing to be making thing (cloth) 3 turnovers, sew up near the folding portion the overlapping thing (cloth) 3 made from 1 upper thread and 1 foundation line, so the cloth decoration prismatic has become coil, therefore exist the cloth decoration rib that can not form the U font, and can not carry out the problem of the seam-ripping sewer that stretches tight easy and simple to handle.
The present invention is in order to solve the problem that exists in described conventional art, its purpose is, when using the sawtooth sewing machine for sewing to form the cloth decoration rib, do not need to carry out the spur adjustment of condition harshness, improve the stability of line states, the work feed stability and the easy observation of making stitch when making of making thing (cloth), under the situation of the skilled technical ability that does not rely on the operator, can easily, efficiently and stably sew evenly cloth decoration rib attractive in appearance.

Above-mentioned structure is to be made of needle plate 11a with hole 12a and work feed tooth 14b or 14c with U groove 15a, also can be shown in Fig. 5 (a) like that, use the combining structure of needle plate 11b and work feed tooth 14b.
Shown in Fig. 5 (a), forming section in the central authorities of needle plate 11b is the U groove 12b of U word shape, rather than the hole.Central authorities in the rear side of needle plate form protuberance, and U groove 12b continues up to the inside of this protuberance.
Central authorities at work feed tooth 14b do not form the U groove, and form hole 15b, and the protuberance and the work feed tooth at the work feed tooth 14b back side are not come in contact.
In addition, also can use the combining structure of needle plate 11a such shown in Fig. 5 (b) and work feed tooth 14c.
Below, use is had the method for sewing that the sawtooth stitch sewing machine of above-mentioned presser feet, needle plate, work feed tooth makes describe.
As shown in Figure 7, the sawtooth stitch sewing machine of present embodiment is except having above-mentioned presser feet 8, needle plate 11a and work feed tooth 14a, and the amplitude of fluctuation that also has pin 31, the needle vibrating mechanism that comprises the needle bar 32 that pin 31 is swung to the left and right and a corresponding pin 31 is by a pair of horizontal rotary hook that carries out mutual counter-rotating 33,34 of position, the left and right sides.Needle plate 11a is configured in the top of horizontal rotary hook 33,34 pars intermedias.The method of sewing that will illustrate is opened among the flat 9-299631 open the spy below.
At first, with reference to Fig. 6, Fig. 7 and Fig. 8, the method for sewing shown in this figure is described.
As shown in Figure 6, the stitching stitch of this Sewing machines is made of needlework (upper thread) Y1 and these 3 lines of 2 bobbin threads (bottom line, rotating shuttle line) Y2, Y3.
Needlework Y1 forms mutual hook with Y1, Y2 and connects (interlacing when swinging; Single line intersects with other lines or other coils).That is, the coil of needlework Y1 passes cloth F from a side of pin, and the bobbin thread Y2 with a side forms hook even in its lower section.Then needlework Y1 is pulled upwardly, makes the cross section of needlework Y1 and bobbin thread Y2 be pulled to the centre of fabric thickness.Then, needlework Y1 is swung to the side of corresponding opposite side bobbin thread Y3, passes cloth F, forms hook with bobbin thread Y3 in its lower section and connects.Then needlework Y1 is pulled upwardly, makes the cross section of needlework Y1 and bobbin thread Y3 be pulled to the centre of fabric thickness.
When work feed being set at interval under the state of fixed amount, when carrying out above action continuously, form the jagged stitch of making on the surface, form the shape of the basic stitch of making as 2 pins overleaf.Shown in Figure 6 is that the amplitude of swinging of needlework Y1 is the stitch of a timing, also can make amplitude of fluctuation carry out systematicness ground and change.
Employed Sewing machines is, have make needle vibrating mechanism that the needle bar that is provided with 1 pin 32 as shown in Figure 7 swings can carry out the transverse arm that the zigzag stitch is made, be respectively equipped with 1 dextrorotary horizontal rotary hook 33 and 1 horizontal rotary hook 34 on the position of the swing width of the corresponding pin 31 in base to anticlockwise.
Because having the transverse arm of described needle vibrating mechanism itself is exactly the transverse arm that people generally understand, so omit detailed explanation at this.
At first, in transverse arm, set the amplitude of fluctuation of pin 31 in the same manner with transverse arm in the past with needle vibrating mechanism.Then, as setting at two-needle type sewing machine in the past, adjust the position (adjustment of rotating shuttle position) of dextrorotation shuttle 33, make its spur 33a can be as shown in Figure 8 right side by needle downing position.
And, pin 31 is moved to the left to the position shown in the chain-dotted line of Fig. 7, do the position adjustment of rotating shuttle 34.At this moment, if two-needle type sewing machine in the past, then because the bore hole portion of each pin is positioned at the outside each other, and the needlework coil is respectively formed at the outside of pin, so spur 34a can just can by the left side of needle downing position as long as the position adjusted to.But, in the Sewing machines that has only 1 pin 31 to swing, because which side no matter the bore hole 31a of pin 31 swing to, all be towards the right side, which position no matter the needlework coil be in, all can be formed on the right side of pin, therefore, must adjust to the position of rotating shuttle and make the spur 34 as illustrated in fig. 8 can be by the right side of needle downing position.Moreover (with identical in the past rotating shuttle), rotating shuttle 34 also must make pin 31 drop to the left side of spur 34a.That is, make spur 34a rise to the outside, and in during the hooking up of needlework coil, make rotating shuttle 34a can not bump against pin 31, must form bigger spur 34a of scope and the gap between the main body.In addition, the A1 among Fig. 7, B1 are respectively the positions of passing through of spur 33a, 34a.
In having the Sewing machines of such structure, for example swing to the right side at pin 31, pass and carry out a little behind the cloth when rising, form the needlework coil at the 31a of bore hole portion of pin 31.The spur 33a of the rotating shuttle 33 on right side hooks up this needlework coil, along with the rotation of spur 33a, needlework twisted in rotating shuttle 33 around, the bobbin thread (Y2) that is drawn out with peg or spindle in rotating shuttle 33 forms hook and connects.Then, by the rising of pin 31 and thread take-up tension lever,, make the cross section of needlework and bobbin thread move to the pars intermedia of fabric thickness the needlework pull-up.Then, pin 31 swings to the left side, carries out and same action in the right side, but as shown in Figure 8, and this needle downing position is the gap in spur 34a left side of the rotating shuttle 34 in left side, and the needlework coil forms hook by this spur 34a and connects.And, owing to pin 31 rises immediately, so spur 34a can not bump against with pin 31 to anticlockwise the time.Other action is identical with the action in the right side, and the bobbin thread (Y3) in needlework and the rotating shuttle 34 forms hook and connects, and afterwards, cross section moves to the pars intermedia of the thickness of cloth.By this a series of action repeatedly continuously, form the stitch of making shown in Figure 6.
Below, with reference to Fig. 9 and Figure 10 the formation method of cloth decoration rib is described.
