Summary of the invention
Task as basis of the present invention is thus, and a kind of method is provided, and is received the limit by the quality ground that its knitwear piece goods just can be also high in the short period of time.
This task has the method solution of receiving limit one knitwear piece goods on the straight-bar machines of at least two opposed needle-bars by one at one, it is characterized in that following steps:
A) at least one is begun-seam loop from this first needle-bar barring-on to this second, do not carry on the needle-bar of coil of this knitted fabric in addition;
B) with this second needle-bar displacement, mutually opposed with at least one adjacent seam loop on this first needle-bar until this at least one seam loop;
C) with this at least one adjacent coil barring-on on limit of will being received on that pin or those pins of having at least one seam loop of this second needle-bar;
D) coil that on that or those pinhock, hangs of braiding (Abstricken) these two and therefore constitute at least one new seam loop;
E) repeat this step b) to d).
The inventive method is different from two barring-on processes in the art methods in order to receive limit one coil and only to need a barring-on process and therefore its enforcement time is significantly shorter than known method.
In addition in the methods of the invention this seam loop not by barring-on.But those next seam loops are hung up on these pins with this seam loop.Then be woven in those two seam loops on this or these sewing needle and constitute a new seam loop.Because this seam loop itself is by barring-on, thus they be not subjected to yet-as they in each barring-on process, produced-excessively stretch.They flexibly are placed on the wale thus.This seam loop can also form the size of a qualification in addition, so can realize a visually beautiful ending.When to one of this seam loop barring-on during with coil that knitted fabric is connected, this coil by barring-on is exactly a coil that is also acting on a traction force on it, so this barring-on process can be carried out relatively reliably.
If during receiving the limit process, reached this needle-bar-needle-bar be loaded with pin with at least one seam loop-the maximum shift stroke, then this at least one seam loop just can by barring-on to a free pin of this mutually opposed needle-bar and this needle-bar that is loaded with sewing needle be brought on its opposed outermost end of the direction of displacement with the current shift position, should receive limit process then and continue operation.
Under the knitted fabric situation of multilayer, all coils can be by barring-on to this first needle-bar, so that can carry out this essential shift movement with this second needle-bar before receiving the limit.Under the cylindrical fabric situation, the coil of this second needle-bar can be by barring-on to the empty needle of this first needle-bar before receiving the limit process.In this way tubular-circle-finished product knitted fabric just can be easily in neckline or also on top pocket ending, on the receipts limit at flange and similar portions place.
The specific embodiment
Fig. 1 .1 and Fig. 1 .2 are that example has shown that the knitwear ending is essential at neckline or running-on place for example according to the receipts limit technology of the firm knitwear ending of the formation one of prior art with a cylindrical fabric.This second needle-bar, promptly back herein needle-bar H can carry out transverse motion.Needle-bar V then can not be traversing in the example of this description before being somebody's turn to do.Natural this needle-bar V, the role of H also can exchange.In addition, also possible on the principle is that two needle-bars can be disposed with staggering.
In the R0 of Fig. 1 .1 line, shown the last knitting line of this tubular-circle-finished product knitted fabric.Fabric is in front and back needle-bar V, the last formation of H.Wherein to have an empty needle of the pin of a coil and another needle-bar opposed with each.In line R1, begin the knitted fabric dorsal part that is positioned on the needle-bar H of this back is received the limit.Outermost end pin 95 with back needle-bar H constitutes a coil for this reason, and this coil is exactly that this begins-seam loop.Then in line R2, this coil by barring-on to the pin 95 of preceding needle-bar V.Then, in line R3, this back needle-bar H is moved two pin positions and this seam loop to the right with regard on the coil on the pin Already in 93 that is hung up on this knitted fabric for this reason.Then in line R4, with outermost end pin 93 these two coils of braiding and therefore constitute new seam loop this moment.Just can receive this whole knitwear dorsal part of limit by the process that repeats in line R2-R4.
The procedure that has shown the receipts limit that is used for the knitted fabric front side in Fig. 1 .2 then is positioned at before this knitted fabric on this preceding needle-bar V.This line R0 has also shown the cylindrical fabric before beginning this receipts limit process.This line is corresponding to the line R0 in Fig. 1 .1.In line R1, with coil of outermost end pin 96 formations of this preceding needle-bar V, this coil is a beginning-seam loop.Then this back needle-bar H in line R2, be moved on its base position and this seam loop by barring-on to the opposed pin 96 of this back needle-bar H.In line R3, with traversing left two the pin positions of needle-bar H, back and with this seam loop from back needle-bar H barring-on to pin 94 on the coil of front there knitted fabric part.Also therefore constitute a new seam loop with these outermost end pin 94 these two coils on pin 94 of braiding then.By repeating just can to have received this whole knitted fabric front side, limit in the step shown in the line R2-R4.
Fig. 1 .1 and Fig. 1 .2 have shown that this seam loop can be constituted a new seam loop by braiding then by twice ground barring-on of difference.Especially the first time during barring-on this seam loop by excess elongation and therefore lost its elasticity.The second time during barring-on this seam loop do not had the pin of coil to deliver in addition by one.On this seam loop that will be delivered, do not acting on enough traction forces thus, so that allowed the barring-on process of this coil that has excessively stretched reliably.
Therefore this method of prior art needs 3 needle movements of each sewing process (Kettelvorgang) and also right and wrong are urgent often in addition.Because the excessive stretching of seam loop, then to make this receipts limit process be partly unreliable and also cause inelastic relatively and visually not too gratifying knitwear to finish up.
Fig. 2 .1-Fig. 2 .8 has shown one according to the method for avoiding these shortcomings of the present invention.It has also shown receipts limit process in an example of receiving the limit cylindrical fabric as Fig. 1 .1 and Fig. 1 .2 the samely.This back needle-bar H is exactly that needle-bar that can carry out transverse motion.As example shown in Fig. 1 .1 and Fig. 1 .2, this linking seam (Kettelnaht) is a coil width herein.But linking seam also can extend by a plurality of pins ground.The version of such broad also is possible in the art methods according to Fig. 1 .1 and Fig. 1 .2.Connection from the wale to the wale only realizes by a seam loop.But this connects also and can realize with a plurality of coils.
Fig. 2 .1-Fig. 2 .8 has shown the dorsal part that is used for knitted fabric and the complete receipts limit process of front side.The receipts limit process that is used for dorsal part is then to begin on the left side in that receipts limit process that is used for the front side that begins on the right side.Naturally, the receipts limit of this dorsal part also can begin to be used for the front side in the left side that receive limit and then begin on the right side.
In line R0, shown according to the cylindrical fabric after the last normal knitting line.Per two pins of needle-bar V and back needle-bar H are all occupied by a coil before being somebody's turn to do.Each is then settled with a unloaded pin mutually opposed to each other by the pin that a coil is occupied.In line R1 all coils of this knitted fabric dorsal part by from back needle-bar H barring-on to these opposed pins of preceding needle-bar V.Therefore produced at the loop construction shown in the line R01.These even number pins are loaded with the coil of this knitted fabric front side and the coil that this uneven number pin is loaded with this knitted fabric dorsal part.
Line R2 has shown the beginning of the receipts limit process that is used for this back knitted fabric side.This back needle-bar H is shifted to the right, until the terminal position that arrives this displacement stroke.Then the coil of this outermost end of this knitted fabric dorsal part from pin 95 barring-ons of this preceding needle-bar V on the opposed pin on the needle-bar H of back.This pin remains the sewing needle KN that is used for the knitted fabric dorsal part on the whole displacement zone of this back needle-bar H (for example 10.16 centimetres acupuncture spacing).This back needle-bar H is by two pins that are shifted left in line R3.Therefore the sewing needle KN that is somebody's turn to do back needle-bar H is mutually opposed with the pin 93 of preceding needle-bar V, and pin 93 was loaded with the outermost end coil of this knitted fabric dorsal part at that time.This coil just by barring-on to the pin KN of this back needle-bar H.In line R4, weave these two coils that on pin KN, hang then.After this coil of this new formation flatly is on this vertically extending wale as seam loop.Can control the elasticity of this knitwear ending by the size of this seam loop.
This back needle-bar H is moved to the left two pins in line R5, so this sewing needle KN is mutually opposed with the pin of the outermost end coil that is loaded with this knitted fabric dorsal part at that time of this front needle-bar V again.Then this coil by barring-on to the pin KN of this back needle-bar H, after this reconstruct a seam loop by this pin KN in line R6, this seam loop reciprocally is connected these two seam loops that are in coil in the pinhock that is front with this edge coil and has therefore set up a connection from a wale to next wale in the horizontal direction.
After this line, should receive the limit loop ends.Two seam loops have just been constituted.This triangle device (Strickschloss) and thread-carrier just can be and for example move on the identical direction in line R3.Repeat the circulation of this receipts limit, received that the limit is over or this back needle-bar H has arrived the terminal position on the left side of its stroke that is shifted until this knitted fabric dorsal part.
In line R7, described, when the terminal position on this left side that reaches this needle-bar displacement stroke, take what measure.Then, the coil of this sewing needle KN by barring-on to its opposed free pin of this preceding needle-bar V.Then, this back needle-bar H moves to the right, on the terminal position that arrives this displacement stroke.After this this seam loop is handed to again on that opposed pin of this back needle-bar H.This pin is then again with the KN nominal.It remains sewing needle, is received intact or this back needle-bar H in limit until this whole knitted fabric dorsal part and has arrived on its shift position on the outermost left side.
This back needle-bar H moves to the right in line R8, until the terminal position that arrives this displacement stroke.This seam loop is handed on the opposed pin of this seam loop of this back needle-bar H.This pin becomes sewing needle KN again, is received that the limit is over or this back needle-bar H has carried out the motion of whole displacement stroke left until this knitted fabric dorsal part.
Other receipts limit circulation of beginning in line R9 then, it is extended to line R12.Needle-bar V was arranged in and is different from the position of line R3-R6 before the pin KN of this back needle-bar H was somebody's turn to do relatively.But this line R3 and R9, R4 and R10, R5 and R11, the process of R6 and R12 is identical.Its coil also should be received the limit if stay next pin separately, then should receipts limit circulates just to be abandoned, as shown in line R13 and the R14.
In line R13, this back needle-bar H is moved two pins left.This moment, this sewing needle KN was mutually opposed with that last pin of this knitted fabric dorsal part.This coil by barring-on to this pin KN.Constitute a coil with this sewing needle KN then in line R14, this coil is connected the seam loop of this front with the last coil of this knitted fabric dorsal part.Therefore this knitted fabric dorsal part has fully been received the limit.
Begin the receipts limit of this knitted fabric front side then.This back needle-bar H pin that is shifted to the right in line R15 for this reason.This seam loop is loaded with to this of this front needle-bar V by barring-on on the pin of outermost left side coil of this knitted fabric front side.In line R16, be somebody's turn to do back needle-bar H by right shift, until the terminal position that arrives its displacement stroke.Except this outermost end coil on the left side coil of this knitted fabric front side by barring-on to those opposed pins of this back needle-bar H.These coils are suspended on even number pin there.Penetrate one and take out line (Trennfaden) on those vacant uneven number pins of this back needle-bar H, this is taken out line that is handed to coil stationary on this sewing needle on the position of its wale, as shown in the line R17.This thread-carrier is moved to the right in line R18, so that this yarn can be penetrated on the pin of this front needle-bar V from this right side.Then the sewing needle KN by this preceding needle-bar V constitutes a coil in line R19, and this coil is connected the last seam loop of this knitted fabric dorsal part with the outermost end coil of this knitted fabric front side.
Then, this real receipts limit circulation of beginning in line R20.This back needle-bar is by two pins that are shifted left.Therefore this pin KN is in that to be loaded with the pin 4 of that outermost end coil of this knitted fabric front side at that time mutually opposed with this of this back needle-bar H.This coil just by barring-on to the pin KN of this preceding needle-bar V.In line R21, constitute this seam loop with this pin KN, seam loop is with two coils that are in the pinhock, therefore that is the seam loop of this front interconnects with this edge coil and set up being connected of a level, connects to extend next wale from a wale.
After this this back needle-bar H is moved two pins again left in line R22.Should before the sewing needle KN of needle-bar V be in again that to be loaded with the pin of outermost left side coil of this knitted fabric front side at that time mutually opposed with that of this back needle-bar H.This coil just is hung up on this pin KN for this reason.Then in line R23 by pin KN, as described in the line R21, constitute a seam loop.This receipts limit circulation is moved to end after this line.Constitute two seam loops.This triangle device and thread-carrier again with as equidirectional passive movement in line R20.The circulation of shown receipts limit is repeated, and is received that the limit is over or this back needle-bar H has arrived the terminal position on its left side of this displacement stroke until this knitted fabric front side.
This line R24 and R25 then explain, this operation measure when the terminal position on this left side that arrives this needle-bar displacement stroke.Then the coil of this pin KN by barring-on to the mutually opposed pin of the pin KN of this back needle-bar H, as shown in the line R24.Then this back needle-bar H is moved right in line R25, arrives its right terminal position until it.After this this seam loop is handed to again on that mutually opposed pin of this preceding needle-bar V, and this pin becomes this sewing needle KN.
Other receipts limit circulation of beginning in line R26, this circulation extends to line R29.Needle-bar H was on other positions that are different from line R20 to R23 after this sewing needle KN was in relatively, but the program shown in this external line R26 to R29 but is same as those programs in line R20 to R23.The circulation of this receipts limit is repeated, and is received that the limit is over or this back needle-bar has arrived its left-hand extremity position of this displacement stroke until this knitted fabric front side.If stay next independent ' coil on due-in limit is arranged ' pin, so should receipts limit circulate and abandoned, this is represented in line R30 and R31.
This back needle-bar H is moved two pins left in line R30, so that last pin of this sewing needle KN and this knitted fabric front side is mutually opposed.This coil by barring-on to that pin KN of this preceding needle-bar V.Constitute a coil with this sewing needle KN then in line R31, this coil is connected the seam loop of this front with the last coil of this knitted fabric front side.Therefore the limit has fully been received in this knitted fabric front side.But this last coil has a connection that is used to take out line.Last for this reason coil in line R32 by barring-on to its opposed pin of this back needle-bar H.Then in line R33, be somebody's turn to do back needle-bar H by right shift, until the terminal position that has arrived this displacement stroke.Constitute one with these pins that form this knitted fabric front side this moment and have the row of taking out line.Then this back needle-bar H is brought on its base position in line R34.This take out the line coil by barring-on to its mutually opposed pin of this preceding needle-bar V.Therefore not only this front side but also rear side have all fully been received the limit.
This receipts limit method of describing in Fig. 2 .1-Fig. 2 .8 is characterised in that: only need two needle movements respectively for knitted fabric dorsal part and knitted fabric front side, so that receive a coil of this knitted fabric of limit.Therefore the relative prior art of this sewing process has obviously been shortened.Because this real seam loop is not by barring-on,, but flexibly be on this coil file so it is not because of barring-on is subjected to excess elongation.This seam loop can form a limited size in addition, thus should receive side seam can be visually by configuration best.
Because a coil that is not this seam loop but this knitted fabric is by barring-on, limited traction force of effect on this coil then, so this barring-on process has been moved relatively reliably.
This receipts limit process is a continuous process as this needle-bar that is loaded with sewing needle can be shifted.In case arrive the end of this displacement stroke, then this seam loop by barring-on to its mutually opposed pin and this needle-bar be brought on that outermost end position opposite with this direction of displacement so far.After this this seam loop by barring-on to its mutually opposed pin of this needle-bar that can be shifted.This receipts limit process can continue to have moved again continuously then.
This method is that example is illustrated with tubular knitwear.But can receive all knitted fabrics in limit with this method, as long as wherein all coils of this knitted fabric can be positioned on the needle-bar.
