[embodiment]

Fig. 1～Fig. 9 represents embodiment, and arrow represents the moving direction of cam carrier, starts and represents that cam system weaves, and stops representing that cam system stops.Fig. 1 represents that cam system S1, S2 are for only carrying out the distribution of the braiding of barring-on, and Fig. 2 represents cam system S1 now, the start/stop of S2.The initial part utilization of knitting width W capable cam system S1 braiding afterwards, decline utilization cam system S2 braiding in advance.Part midway can be utilized either one or both braiding of cam system S1, S2.In the example of Fig. 1, Fig. 2, the knitting width of initial part and back-page knitting width are set for respectively with the width of 1 cam system and are equated in addition.

The solid line of Fig. 2 represents preferentially to use the example of cam system S2, and dotted line represents preferentially to use the example of cam system S1, in arbitrary situation, all exist use simultaneously cam system S1, S2 during.In addition as shown in Figure 1 and Figure 2, in the long situation of knitting width W, stroke L and the knitting width W of cam carrier are substantially equal, if with Figure 10 comparison, stroke shortens along the width of 1 cam system of the length direction of needle-bar.And this situation is advantageous particularly in the more braiding of barring-on, but also embodiment can be applicable to the payment of coil except barring-on.

Fig. 3 represents to possess situation on the cam carrier of 3 cam system S1, S2, S3, that cam system S1, S2, S3 distribute to the process of only carrying out barring-on.Fig. 4 represents that cam system S1, S2, S3 are for the distribution example of the process of Fig. 3, and solid line represents preferentially to use the example of cam system S2, and dotted line represents preferentially to use the example of cam system S1.In the situation of Fig. 3, Fig. 4, stroke L is shorter than knitting width W, and cam system S1 is used in the beginning of knitting width, and the latter end of knitting width is used cam system S3.At the central portion of knitting width, use cam system S1, S2, S3 at least 1,2 or 3 of also can use cam system S1, S2, S3.Between central portion and the beginning of knitting width, use at least one of cam system S1, S2, between central portion and the latter end of knitting width, use at least one of cam system S2, S3.In this example, exist use simultaneously cam system S1, S2 during and use simultaneously cam system S2, S3 during.

Fig. 5 represent to restrict example of braiding process of shape decorative pattern, by repeatedly carrying out process C1～C6, kernmantle shape decorative pattern.Cam carrier possesses 2 cam systems, in process C1～C3, each process is woven respectively to 2 row coil columns, amounts to braiding 6 row.In process C4, make coil barring-on, after making before process C5, needle-bar is traversing to the left, and half part that makes the coil after barring-on forward needle-bar moves and returns.And needle-bar is traversing to the right after making before process C6, make remaining coil after barring-on forward needle-bar move and return.

In process C4, the latter end of knitting width is cam system in advance, if more than not weaving the width of 1 cam system, stroke extends.This be because, if the latter end of the knitting width of the width of 1 cam system of less than is just assigned to cam system in advance, the part that capable cam system braiding has distributed afterwards, therefore stroke extends to the left compared to existing technology.In addition any cam system braiding of also can utilize in advance/rear row of the beginning of knitting width.In this case, no matter whether be suitable for embodiment, stroke does not change, and when the cam system of row can weave the beginning of knitting width after only utilizing, can shorten stroke.

In process C5, C6, after utilizing in an embodiment, the cam system of row takes up one's knitting, and utilizes cam system in advance to finish braiding.After for example utilizing in the prior embodiment with respect to this, the cam system of row weaves process C5 consistently, utilizes cam system in advance to weave consistently process C6.So, in process C5, C6, can make in an embodiment stroke shorten the width of 1 cam system.For 6 processes of cam carrier, when the stroke that can make to add up to shortens 2 times of width of cam system, braiding time shorten is counted %.

Fig. 6 represents can shorten by embodiment the lower limit of the knitting width of stroke.Fig. 6 1) represent the stroke in embodiment, 2) represent the stroke in conventional example.Fig. 6 1) in, the knitting width of the initial part of the cam system S1 braiding by rear row equates with the width of 1 cam system with the back-page knitting width sum that the cam system S2 by advance weaves, and now in embodiment and conventional example, stroke is all equal.In addition Fig. 6 1) in, the knitting width of initial part equates with knitting width W with back-page knitting width sum.In the situation that the knitting width of initial part equates with the width of 1 cam system with back-page knitting width sum, in embodiment, according to the initial position of the cam carrier with respect to knitting width, the distribution of cam system changes.But in either case, the stroke L1 of cam carrier is the 2W of 2 times of the width of cam system.In conventional example, weave in the situation of knitting width W, the stroke of the width that cam carrier must a mobile knitting width W+1 cam system, stroke is 2W in this case.Therefore, in the situation that knitting width W equates with the width of 1 cam system, the stroke of embodiment and conventional example intermediate cam seat balladeur train equates.

Fig. 7 represents the processing relevant with the shortening of stroke, utilizes the lopping design apparatus 10 of Fig. 8 or the straight-bar machines of Fig. 9 30 to implement.In the step 1 of Fig. 7, weave data is read to 1 process, and whether be the process of using thread-carrier, if do not use the process of thread-carrier if in step 2, differentiating, for example carry out the process of barring-on or payment, check the cam system (step 3) that whether has unallocated braiding.Then differentiate whether can to take knitting width and the back-page knitting width sum of the initial part on the direct of travel of cam carrier be 1 width more than cam system, and cut apart knitting width (step 4) in the initial part mode different from the cam system of decline use.In impartible situation, utilize as prior art identical cam system to carry out the barring-on of whole 1 process.In the situation that can cutting apart, with the cam system of going after utilizing according to embodiment in step 5, take up one's knitting, utilize cam system in advance to finish the mode weaving, distribute cam system.Between the initial part and decline of braiding, utilize either one or both of cam system of cam system in advance and rear row to weave, if there is no end process (step 6) of next process.Can shorten stroke thus.This external position that also can take up one's knitting from the cam system of utilizing in advance starts the situation of process, and whether applicable embodiment all can.
