Then, starting to main cloth LI(or RO) upper while supplying with strap Tm, as shown in figure 22, front conveying roller 381 is rotated, strap Tm is supplied to suture needle 22 belows, with suture needle 22 and be connected in main cloth LI(or RO) on the NT butt of reaching the standard grade.In addition, Tm1 is the front strap once sewing up.

Then, as shown in figure 23, utilize X-Y feed arrangement to make main cloth LI(or RO) move along the strap direction of the supply, and, by being rotated, front conveying roller 381 carries strap, thereby at main cloth LI(or RO) on strap Tm upper, suture needle 22 is run through and be more than or equal to 2 times, in utilization, roll off the production line strap Tm and main cloth LI(or RO) sew up.

Now, make the action of X-Y feed arrangement, with for example, according to (making spacing with common, 2mm～2.5mm) (for example compare 1mm left and right little, 0.7mm～1.3mm) little width make spacing and carry main cloth, and, make motor M1 action, with the strap amount of feeding is now become and stitching spacing equivalent or and the amount of feeding of 2 times of stitching spacing between the amount of feeding.For this actual strap amount of feeding is changed along with the characteristic (hardness, flexible, smoothness) of the strap using, make the setting amount of feeding of motor M1 can in display unit 6, set change.

; make strap on the main cloth to shoes time; on main cloth, form and make after the stitching that beginning is at least more than or equal to 3 pins; making of strap started to precalculated position and be supplied to suture needle below; on the strap on main cloth; with with common make spacing compare little little width make spacing form be more than or equal to after the stitching of 2 pins, on main cloth, make strap with the above-mentioned common spacing of making.

In addition, the movement of main cloth is undertaken by X-Y feed arrangement, that is, this X-Y feed arrangement makes to support the main cloth press section of main cloth along a planar movement of level.

In addition, if when make the stitching that spacing is more than or equal to 2 pins with little width, at every turn to make the Length Quantity of spacing corresponding (for example with being at least more than or equal to little width, preferably be more than or equal to little width make spacing～little width make in the scope of 2 times of spacing carry), the strap amount of feeding is extracted out along making spacing direction of feed, in the time that strap is made, made exactly strap.

In addition make the strap of linearity on the main cloth to shoes time, because (X-direction) along its length forms stitching, be that X-direction forms so make spacing direction of feed along the strap direction of feed (strap feed path) of strap feedway 3.

In addition, the method to making strap on the main cloth of shoes as noted above, can be applied in strap apparatus for sewing, and this strap apparatus for sewing is the device of making strap on the main cloth of shoes, has: workbench, and it is for arranging main cloth; X-Y feed arrangement, it makes to support the main cloth pressing of main cloth along a planar movement of level; Strap feedway, it supplies with strap on main cloth; And Sewing machines, it makes strap based on tailoring pattern on main cloth.In addition, can also be applied in the strap apparatus for sewing with the middle presser feet that suture needle runs through.

Then, carry main cloth LI(or RO with the common spacing of making), and strap Tm is made.

As noted above, in the time making beginning, suture needle 22 is run through, to make spacing with the common little width of making the 1mm left and right that spacing compares little, at main cloth LI(or RO) on upper the formation while being more than or equal to the stitching of 2 pins of strap Tm, as shown in figure 24 so that middle presser feet 23 drops to the mode of the height that is equivalent to main fabric thickness amount, middle presser feet 23 is declined, to main cloth LI(or RO) on press strap Tm.Thus, at main cloth LI(or RO) on keep reliably strap Tm.

Then, while making strap Tm, making the height of middle presser feet 23 get back to common height with the common spacing of making, that is, and the height suitable with main fabric thickness+strap amount of thickness.

Be placed on the strap Tm of for example bandpass of rectangular strap T(on strap stand 4), because length exists restriction, institute is so that the top of end and other straps T is overlapping, waits connection use by bonding.Because this lap is not suitable for making, so conventionally must excise before making.In the present embodiment, on the TG of strap seam portion (strap seam), be pasted with the golden zone of reflections.

In addition, if be the finish command between correction zone (step S2632, no) in S2632, end process.

With reference to Figure 40 (a) and Figure 40 (b), step S2631 and step S2633 are elaborated.

Figure 40 (a) is the tailoring pattern in the width corrected value of the strap situation that is 0, and Figure 40 (b) operates movable strap guide portion 35 operating personnel, makes the tailoring pattern in situation that cloth bandwidth increases.They are all by needle falling point e → f → (g-1) → g → h → (h+1) → i.If the spacing between each needle falling point is made as to 2mm, the interval between (g-1) and g, h and (h+1) between be spaced apart 2mm.

For example, if make cloth bandwidth increase 0.5mm at Y direction front side, locate at the needle falling point (g-1) of the last pin of needle falling point g, only make the composition additional width corrected value 0.5mm of Y direction, determine new needle falling point g coordinate (old g coordinate (x, y) → new g coordinate (x, y+0.5)).This means, if initiation command between correction zone is is added and subtracted width corrected value and next pin is made in the amount of movement of stitch data.

In addition, if make cloth bandwidth increase 0.5mm at Y direction front side, locate at the next needle falling point (h+1) of needle falling point h, deduct width corrected value 0.5mm, h and spacing spacing (h+1) become 1.5mm.This means, if the finish command between correction zone is is added and subtracted width corrected value and next pin is made in the amount of movement of stitch data.

Its result, utilize between this correction zone the finish command between initiation command and correction zone, by control module (control cabinet 5), multiple needle falling points (g to h) of movable strap guide portion side being carried out to interval specifies, corresponding with the amount of movement of movable strap guide portion, make to have carried out the multiple needle falling point parallels after interval appointment, generate tailoring pattern.

In step S2604, (step S2604 in the absence of strap seam (cloth belt lacing) TG, no), abutment joint marks whether to judge (step S2605) for connecting, if splice marks is not to connect (step S2605, no), make cutter (cutting knife 301) rising (step S2606), rear conveying roller 382 is declined (step S2607), to check the strap Length Quantity conveying strap T(step S2608 of regulation definite in the step S2403 of (step S24) at the IO of Figure 34 sensor).

Then, cutter (cutting knife 301) is declined (step S2609), strap T is cut off with specific length, make front conveying roller 381 decline (step S2610).

Then, in order to make main cloth and suture knotting, and (for example only on main cloth, make several pins, be more than or equal to 3 pins) (step S2611), then, before utilizing, conveying roller 381 is carried strap T, makes the knotting part butt (step S2612) of strap T and main cloth and suture.The strap of carrying is transported to suture needle below, is the position that can make with main cloth.The strap T of this position is made as to strap and makes beginning precalculated position.

As noted above, making under original state, cutter (cutting knife 301) is declined, and front conveying roller 381 is declined, operating personnel supplies with the strap T of specific length.

Then, in order to make the knotting of strap and main cloth, and strap T is extracted out, make spacing (1mm left and right, for example, 0.7mm～1.3mm) with little width simultaneously and make several pins (step S2613).

Then, after making, conveying roller 382 declines after (step S2615) and continues to make.The combination by suture of strap T and main cloth, by utilizing feeding (upper presser feet 12, lower plate 11) that main cloth is moved, thereby constantly pulls out the required amount of stitching spacing.Then, again return to the processing of step S2601.

In addition, in step S2604, there is (step S2604 in the situation of strap seam TG, be), splice marks (joint marker) is made as to connection (step S2616), by until the length of seam is made as C(fixes from strap seam sensor 303 to the length of cutting knife 301) (step S2617).

Then, to whether until the length C > cloth strip length of strap seam TG judges (step S2618), if not until length C > cloth strip length (the step S2618 of strap seam TG, no), in the display frame of display unit 6, show seam mistake (joint mistake) (step S2619), as shown in figure 26, discharge (step S2620) by comprising strap seam TG at interior strap.

Then, as shown in figure 27, according to the state of cloth belt sensor 305, whether the strap detecting after discharging is removed (step S2621), (step S2621 in the removed situation of strap, be), the not shown seam false solution showing in the display frame in display unit 6 except (step S2622), is waited for starting SW(and starting switch) 20 press (step S2623).Then, splice marks is made as to disconnection (step S2624), again returns to the processing of step 2606.

In addition, whether the strap after the discharge of step S2621 is removed, and is to differentiate according to the switching state of the detection of cloth belt sensor 305.As shown in Figure 38 (a)～Figure 38 (c), in situation arbitrarily, if strap is removed, the detection of cloth belt sensor 305 becomes the state of " disconnect → connect ", by this switching state is detected, thereby the strap that can be judged as after discharge is removed.

In addition, in step S2605, if splice marks is for connecting (step S2605 is), the processing that enters step S2618.

In addition, in step S2618, if until the length C > cloth strip length of strap seam TG (necessary cloth strip length) (step S2618, be), by until the length of strap seam TG, be made as until length-Bu strip length (step S2625) of strap seam TG returns to the processing of step 2606 again.

As noted above, the detection of strap seam TG is to utilize strap seam sensor 303 to carry out at the upstream side of strap feed path, compared with necessary cloth strip length, without supplying with lavishly strap.

In Figure 29, after making (step S26), make presser feet 12 increase (step S27), make thing and reclaim the processing (step S28) of waiting for.

In Figure 29, make strap feedway 3 move (step S28) to workpiece setting position, make pending (step S29) such as thing recovery.

In addition, in Figure 29, in step S25, the inspection of IO sensor is not (step S25, no) in normal situation, enters step S29.
