Each 100A of bevel tool mechanism, 100B are set up in parallel along cloth direction of feed F, and the 100A of bevel tool mechanism is configured in the rear of the 100B of bevel tool mechanism.That is, the 100A of bevel tool mechanism can form a pair of oblique joint-cutting in the rear end side of straight line joint-cutting S, and the 100B of another bevel tool mechanism can form a pair of oblique joint-cutting in the front ends side of straight line joint-cutting S.And only the 100B of bevel tool mechanism utilizes cell moving motor 90 (with reference to Figure 10), can install with respect to sewing machine table 11 along cloth direction of feed F running fix ground.Below, under the situation that two bevel tool mechanisms are described respectively, sometimes the 100A of bevel tool mechanism is called " fixation side ", the 100B of bevel tool mechanism is called " mobile side ".In addition, also can be the 100A of bevel tool mechanism, 100B the two all on the cloth direction of feed, move.
In addition, 100A of bevel tool mechanism and the 100B of bevel tool mechanism, owing to adopting is the roughly the same structure that benchmark forms the minute surface symmetry with Y-Z plane mutually, so only cutting on the cross cutter mechanism 100B is elaborated, each structure to the 100A of bevel tool mechanism that becomes the minute surface symmetric construction, mark identical label, omit explanation.
The 100B of bevel tool mechanism has: four bevel tools 101,102,103,104; Unit main body 105, its a pair of axis of guide 14 by the pole shape of the lower face side that is disposed at workbench 11 supports; Transposition portion 106, it is block tectosome, in the recess 105a on the rear side surface that is formed at unit main body 105, can be supported movably along Y direction, keep each bevel tool 101～104 simultaneously; As the travel mechanism of transposition portion 120 of bevel tool selection mechanism, it carries out running fix along Y direction to transposition portion 106; And reciprocating mechanism 130, it utilizes the co-operating with travel mechanism of transposition portion 120, selects bevel tool and it is moved up and down.
Unit main body 105 is the frame shape, and is supported with the state that inserts a pair of axis of guide 14 in an end of Y direction.In addition, on a side of the rear side that becomes unit main body 105, form recess 105a, in the inboard of this recess 105a configuration transposition portion 106.And, the support that is fixed of the unit main body 105 of the 100A of bevel tool mechanism, and the unit main body 105 of the 100B of bevel tool mechanism via not shown belt feed mechanism or ball screw framework, can be located on the optional position of X-direction by the driving of cell moving motor 90.In addition, also can use linear motor as cell moving motor 90.
In transposition portion 106, fixed installation is from extended two support bars up and down of upper edge, the side Y direction of its Y direction, be arranged at inserting in the hole of unit main body 105 sides by these support bars are inserted, thus realize transposition portion 106 with respect to unit main body 105 along the supported movably state of Y direction.
Upper surface in transposition portion 106 is provided with four bevel tool erecting beds 107,108,109,110, and each erecting bed 107～110 keeps bevel tool 101～104 respectively.These erecting beds 107～110, by unclamping not shown fastening bolt, can carry out each bevel tool 101～104 around the angular adjustment (with reference to Fig. 9 (A)) of Z axle, and can by manual operations regulate point of a knife towards angle of inclination (with reference to Fig. 9 (B)).Each bevel tool 101～104 determines the angle of inclination that oblique joint-cutting forms with respect to straight line joint-cutting S by the angular adjustment around the Z axle, by regulate point of a knife towards the angle of inclination, determine the shearing length of oblique joint-cutting.
The adjustment example of each bevel tool 101～104 of observing from the top here, is described based on Fig. 8 (B).Two bevel tools 101,102 on right side are used to form the oblique joint-cutting that is formed at the right side with respect to straight line joint-cutting S, all tilt towards the place ahead and to the direction of keeping right, but bevel tool 102 so that the elongated mode of the shearing length of oblique joint-cutting tilt.In addition, being adjusted into width h1 and the h2 of oblique joint-cutting on Y direction that is formed by each bevel tool 101,102 equates.
Two bevel tools 103,104 in left side are used to form the oblique joint-cutting that is formed at the left side with respect to straight line joint-cutting S, and it all tilts towards the place ahead and to the direction that keeps left, but bevel tool 104 so that the elongated mode of the shearing length of oblique joint-cutting tilt.In addition, with the situation of each bevel tool 101,102 in the same manner, be adjusted into width h1 and the h2 of oblique joint-cutting on Y direction that forms by each bevel tool 103,104 and equate.That is, bevel tool 101,103 is equivalent to " short cutting knife ", and bevel tool 102,104 is equivalent to " long cutting knife ".
In addition, each erecting bed 107～110 has sliding axle along Z-direction (omitting diagram) at its downside, utilizes this slip, can be supported by transposition portion 106 up or down.And in the bottom of this each sliding axle, forming the engaging protrusion of forwards protruding is shears 107a～110a.These shearss 107a～110a more forwards protrudes than the front surface of transposition portion 106, and reciprocating mechanism 130 described later moves up and down each bevel tool 101～104 via these shearss 107a～110a.
Travel mechanism of transposition portion 120 has: as the transposition portion motor 121 of positioning motor, it is fixedly mounted on the top of unit main body 105; Thread spindle 122, it is driven by 121 rotations of transposition portion motor; And moving body 123, it is connected with this thread spindle 122 via ball-screw.
Thread spindle 122 rotatably is supported on the upper surface of unit main body 105 with the state along Y direction, and the one end links via the output shaft of shaft coupling and transposition portion motor 121.
Extended arm 106b keeps moving body 123 from Y direction one end by transposition portion 106.Thus, if thread spindle 122 utilizes transposition portion motor 121 to be driven in rotation, then moving body 123 bears locomotivity owing to the effect of ball screw framework on the length direction (Y direction) of thread spindle 122, and the Y direction of carrying out transposition portion 106 moves.
The Y direction of the transposition portion 106 that is undertaken by travel mechanism of described transposition portion 120 moves, when a pair of bevel tool of from each bevel tool 101～104, selecting to move up and down described later, use, simultaneously use to the forming the position of position on Y direction and regulate of the oblique joint-cutting that forms by the bevel tool of selecting the time by reciprocating mechanism 130.
Reciprocating mechanism 130 has: the 1st cylinder 131, and it rises bevel tool, thereby forms oblique joint-cutting on the right side of straight line joint-cutting S; The 2nd cylinder 132, it rises bevel tool, thereby forms oblique joint-cutting in the left side of straight line joint-cutting S; As the cylinder bracket 133,134 of engaging part, it is arranged on the output shaft of each cylinder 131,132, selectively engages with aforementioned shears 107a～110a.
Each cylinder 131,132 is installed on the unit main body 105 in its direction of action mode parallel with Z-direction.
Each cylinder bracket 133,134 is only to make the axial mid portion pathization of cylinder and the drum type parts that form, makes its center line under the state of Z-direction, is installed on the output shaft of each cylinder 131,132.And, each cylinder 131,132 and each cylinder bracket 133,134 are disposed on the unit main body 105, so that carry out when mobile along Y direction in transposition portion 106, the leading section of each shears 107a～110a by each cylinder bracket 133,134 by between the position of pathization.
Promptly, if transposition portion 106 moves along Y direction, then since each shears 107a～110a by between this minor diameter part of putting in order by each cylinder bracket 133,134, so the transposition portion motor 121 by travel mechanism of control transposition portion 120 is so that become between the minor diameter part that the shears of the bevel tool of action object stops at cylinder bracket 133 and 134, thereby the shears of regulation is engaged with cylinder bracket, can utilize the driving of the 1st or the 2nd cylinder 131,132, make the bevel tool of regulation carry out lifting action.
In addition, the transposition portion sensor 111 (with reference to Figure 10) that has optical profile type at the lower surface of unit main body 105, it detects transposition portion 106 and is in following three positions: the shears 107a of (1) bevel tool 101 is positioned at the position that engages with cylinder bracket 133, and the shears 109a of bevel tool 103 is positioned at the situation of the position that engages with cylinder bracket 134 simultaneously; (2) the shears 108a of bevel tool 102 is positioned at the situation of the position that engages with cylinder bracket 133; And the shears 110a of (3) bevel tool 104 is positioned at the situation of the position that engages with cylinder bracket 134, utilizes described sensor and carries out the positioning control of transposition portion 106.And, the state of above-mentioned (1)～(3) is called the state that each bevel tool 101～104 is positioned at operating position.
In addition, because the scope that each cylinder bracket 133,134 overlaps with each shears 107a～110a, shown in Fig. 8 (C), on Y direction, has certain width, even, also can keep fastening state so that each shears 107a～110a moves in Y direction with respect to each cylinder 133,134 is a certain amount of.And, can in the scope that can keep this fastening state, each bevel tool 101～104 be moved on Y direction, carry out the position adjustments of off-position.

In addition, action control unit 80 is via driver, connects to drive respectively to make to keep the cylinder that body 30 moves up and down and make big presser feet 21,21 carry out the electromagnetic valve of the cylinder of lifting (omitting diagram).In addition, in the same manner,, connect transposition portion motor 121, carry out the electromagnetic valve 135,136 and the above-mentioned transposition portion sensor 111 of the 1st and the 2nd cylinder 131,132 of bevel tool lifting via driver 121a, 135a, 136a, input circuit 111a.
In addition, action control unit 80 connects the not shown cutter driving air cylinder driven that is used to drive the cutting knife that carries out the suture cut-out and switches solenoid 43 with electromagnetic valve 89 and aforementioned pin via driver 89a, 43a.
In addition, bevel tool mechanism is provided with two, but in Figure 10, about the structure of bevel tool mechanism, only illustrates this internal structure of the 100B of bevel tool mechanism, to the 100A of another bevel tool mechanism, omits its internal structure and illustrates.
Action control unit 80 has: CPU 81, and it carries out various processing and control; ROM82, its write to the various settings of fillet sewing machine 10 import processing setting input program 82a, carry out first of Sewing machines action control in the filler rod and cut off that control program 82b and second cuts off control program 82c and the center joint-cutting forms control program 82d; As the RAM 83 of working region, it is store various kinds of data in the processing of CPU 81; And EEPROM 71, its record stitch data and various setting data.
(setting input program)
When carrying out filler rod, import by showing that input block 85 is set in advance: the left and right sides straight line stitching TL on the cloth direction of feed F, the leading section position PFL of TR, PFR and rearward end position PRL, PRR (with reference to Fig. 2), with two straight line stitching TL, the corresponding end position XS of straight line joint-cutting S on X-direction that forms by center joint-cutting 51 in the end of TR, be to cut off control or second by described later first to cut off the selection that the forms setting that the angle joint-cutting is carried out in control, in each pin by big presser feet 21, the 21 cloth B that produce, the amount of feeding of M is set, and these data are stored among the EEPROM 71.
Fillet sewing machine 10 has mark lamp (not shown), its become the main cloth M that makes object and filler rod cloth B operation is set the time, the assigned position of irradiation workbench, as one man be provided with by the irradiation position of making starting position or end position and described mark lamp, can begin to make from the precalculated position these clothes with main cloth M and filler rod cloth B.
In above-mentioned fillet sewing machine 10, to be arranged on correct assigned position be prerequisite to become the main cloth M that makes object and filler rod cloth B, carries out the action control of cloth feeding.Promptly, as long as main cloth M and filler rod cloth B are arranged on assigned position, just can know when when carrying out big presser feet 21,21 mobile to a certain degree, predefined " leading section position PFL, PFR and rearward end position PRL, the PRR of left and right sides straight line stitching TL, TR on the cloth direction of feed F " whether be positioned at each suture needle 41,41 under the position, thus, to main cloth M and the filler rod cloth B that sends here by big presser feet 21,21, calculate the control of the timing of making beginning and sewing finishing of each straight line stitching TL, TR.
Therefore, if CPU 81 is according to setting input program 82a, from showing leading section position PFL, PFR and rearward end position PRL, the PRR of left and right sides straight line stitching TL, TR on the input block 85 input cloth direction of feed F, then carry out its value is stored in processing among the EEPROM 71.
In addition, CPU 81 is according to setting input program 82a, leading section position PFL, PFR and rearward end position PRL, PRR according to left and right sides straight line stitching TL, TR on the cloth direction of feed F, PFL is subtracted PFR and calculates anterior end position deviation CF, PRL is subtracted PRR and calculates rearward end position deviation CR, be stored among the EEPROM 71.
In addition, if CPU 81 determines the anterior end position FE of straight line joint-cutting S and the information of rear end position RE (with reference to Fig. 1, Fig. 2) according to setting input program 82a from showing input block 85 inputs, then its value is stored among the EEPROM 71.Figure 11 is illustrated in the make decision key diagram of example of anterior end position FE of straight line joint-cutting S of the situation of carrying out filler rod shown in Figure 2.
As noted above, owing to carry out the angular adjustment (with reference to Fig. 9 (A)) around the Z axle of each bevel tool 101～104, with utilize manual operation regulate point of a knife towards angle of inclination (with reference to Fig. 9 (B)), so action control unit 80 is in order to determine and straight line stitching TL, the end position of the corresponding straight line joint-cutting of the end position of TR S on cloth direction of feed (X-direction), need to adjust each bevel tool 101～104 around the angular adjustment of Z axle and point of a knife towards the angle of inclination, utilize the information that the anterior end position FE of straight line joint-cutting S (also record and narrate and be leading section position FE) or rearward end position RE (also record and narrate and be rearward end position RE) are determined in input program 82a input of setting simultaneously.
For example, existence is cut off the situation that filler rod is carried out in control with first, promptly, oblique joint-cutting (VFL and VFR) at the left and right sides across straight line joint-cutting S shown in Figure 2, utilization is two cutting knifes 101 and 103 of short cutting knife, an end that makes each oblique joint-cutting when making each other shearing length (CLS) equal is consistent with the end of corresponding respectively straight line stitching, under this configuration, form oblique joint-cutting, in the case, in fact the operator is forming straight line stitching TL, in the time of TR, for each bevel tool 101,103, equally adjust around the angular adjustment of Z axle and point of a knife towards angle of inclination (θ 1), when the joint-cutting of the angle of formation expectation, with the length X S of oblique joint-cutting VFR on the cloth direction of feed, as the information input of the anterior end position FE that determines straight line joint-cutting S.Then, action control unit 80 is according to setting input program 82a, the length X S in EEPROM 71 on this cloth direction of feed of storage.Though diagram is omitted, for the rearward end RE of straight line joint-cutting, also in the same manner with the length on the cloth direction of feed of oblique joint-cutting VRL, as the information input of determining rear end end position RE.In the case, EEPROM 71 works as memory cell, and its storage is by being the bevel tool 101 of short cutting knife or the length X S of shearing length on the cloth direction of feed of the oblique joint-cutting that bevel tool 103 forms.
And, length X S on this cloth direction of feed for example uses in the following cases, promptly, carrying out cutting off control with first and carry out under the situation of filler rod as shown in figure 11, CPU81 forms control program 82d by implementation center's joint-cutting, with the definite anterior end position of position FE as straight line joint-cutting S, this position FE, be from two straight line stitching TL, the end PFR of a relatively extended side straight line stitching TR begins in the TR, to the non-extension side of straight line stitching TR, the position behind the deflection length X S (shearing length that is formed by short cutting knife is in the length on the cloth direction of feed).
In addition, length X S on this cloth direction of feed for example uses in the following cases, promptly, carrying out cutting off control with second and carry out under the situation of filler rod as shown in figure 12, CPU81 forms control program 82d by implementation center's joint-cutting, determine the anterior end position of position FE as straight line joint-cutting S, this position FE, be from two straight line stitching TL, the end of relatively not extended side straight line stitching TL begins in the TR, to the non-extension side of straight line stitching TL, the position behind the deflection length X S (shearing length that is formed by short cutting knife is in the length on the cloth direction of feed).
In the case, as Figure 11 and shown in Figure 12, make the anterior end position FE of straight line joint-cutting S, with in two straight line stitching TL, the TR relatively the end position PFR of extended stitching be benchmark and under the situation about determining uniquely, owing in the first cut-out control and the second cut-out control, become XS and these two different values of XL respectively, XL changes along with the tilt angle theta 2 of long cutting knife simultaneously, so the operator when determining the end position FE of straight line joint-cutting S, needs very numerous and diverse input operation.
But, carry out above-mentioned center joint-cutting by CPU 81 and form control program 82d, with can be only based on the length X S of shearing length on the cloth direction of feed of short cutting knife, the mode of the anterior end position FE of decision straight line joint-cutting S, corresponding with selecteed cut-out control program and automatically change the reference position, determine the anterior end position FE of straight line joint-cutting S, so the operator only imports the length X S of shearing length on the cloth direction of feed that is formed by short cutting knife, just can set the anterior end position FE of straight line joint-cutting S, switching first and second when cutting off control or when readjusting the tilt angle theta 2 of long cutting knife, can reduce the working load of information (XL) etc. that the anterior end position FE of straight line joint-cutting S is determined in further input.
In addition, Figure 11 and Figure 12 are the key diagrams under the situation of the anterior end position FE that determines straight line joint-cutting S, but, also can only determine with the length of shearing length on the cloth direction of feed that forms by corresponding short cutting knife in the same manner by input for the rearward end position RE of straight line joint-cutting S.
In addition, " cutting off control by first still is the selection setting that the second cut-out control is carried out ", be to be used for when forming the angle joint-cutting, selecting carrying out first to cut off which the setting that control program 82b and second cuts off control program 82c, undertaken by the operation that shows input block 85 by the operator.
" amount of feeding by cloth B, the M of big presser feet 21,21 in each pin is set " is so-called cloth feed speed.That is, by controlling big presser feet feed mechanism 20, make with the moving up and down speed synchronization of suture needle and in each pin, move, thereby can make with constant space with the regulation amount of feeding.In addition, in other straight line joint-cutting S or the formation of angle joint-cutting control since with make in each pin big presser feet 21 with the regulation amount of feeding move be prerequisite decision action regularly, so must preestablish amount of movement in each pin.And, when the action control of filler rod,,, judge cloth M, B are positioned at which position (position on the cloth direction of feed) according to elapsed time from the action beginning with reference to the amount of movement in each pin that is stored in the EEPROM 71, carry out exercises control.
" 100B of bevel tool mechanism when the angle joint-cutting forms is with respect to the amount of movement of the 100A of bevel tool mechanism " is 100A of bevel tool mechanism when forming the angle joint-cutting on the end, front and back of straight line stitching TL, TR and the separating distance between the 100B of bevel tool mechanism.Promptly, in the time of in the configuration that cloth M, B is transported to each 100A of bevel tool mechanism, 100B, driver element travel motor 90, make 100A of bevel tool mechanism and the 100B of bevel tool mechanism become corresponding and state that separate with the length of straight line stitching TL, TR, thus, on the end, front and back of straight line stitching TL, TR, can form the angle joint-cutting simultaneously.For example, can be set at the consistent value of length with straight line joint-cutting S.
(the angle joint-cutting of filler rod forms control: first cuts off control)
The angle joint-cutting of filler rod forms control, and first among the above-mentioned ROM 82 cuts off control program 82b and the second cut-out control program 82c carries out by being stored in.That is, by carrying out said procedure 82b, 82c, CPU 81 works as first control module.
First cuts off control program 82b makes CPU 81 carry out first to cut off the program of controlling, this first cut off control for make big presser feet feed mechanism 20 push motor 23 and the 100A of bevel tool mechanism, 100B form angle joint-cutting shown in Figure 2, for oblique joint-cutting VFL, VFR (or VRL, VRR) across the left and right sides of straight line joint-cutting S, an end that makes each oblique joint-cutting VFL, VFR (or VRL, VRR) when each other shearing length equates is consistent with the end of corresponding straight line stitching TL, TR, formation angle joint-cutting under this disposes.
On the other hand, second cuts off control program 82c is undertaken second by CPU 81 to cut off the program of controlling, this second cuts off control and pushes motor 23 and the 100A of bevel tool mechanism for what make big presser feet feed mechanism 20,100B forms angle joint-cutting shown in Figure 3, for oblique joint-cutting VFL across the left and right sides of straight line joint-cutting S, VFR (or VRL, VRR), when making mutual shearing length different, make each oblique joint-cutting VFL, VFR (or VRL, VRR) both ends and corresponding respectively straight line stitching TL, the end of TR is consistent with the end of straight line joint-cutting S, forms the angle joint-cutting under this configuration.
Above-mentioned first and second cuts off control program 82b, 82c, which is carried out by being selected to set as the demonstration input block 85 of selected cell by operator's utilization, thereby CPU 81 is according to selecting execution.Below, describe first and second respectively in detail and cut off control.
In the formation of angle joint-cutting, in the formation of the angle of anterior end joint-cutting, use the bevel tool 100B of mechanism, in forming, uses the angle of rearward end side joint-cutting the bevel tool 100A of mechanism.Here, be that example describes with the angle joint-cutting that forms the leading section side.
Cut off in the control first, use the bevel tool 101 and 103 of the bevel tool 100B of mechanism.Promptly, CPU 81 is after utilizing big presser feet feed mechanism 20 to make the leading section PFR angle of arrival cutter mechanism 100B of straight line stitching TR of cloth M, B, at first, bevel tool 101 forms oblique joint-cutting VFR by being risen, then, after utilizing big presser feet feed mechanism 20 supply side position offset difference CF amount, make bevel tool 103 risings and form oblique joint-cutting VFL.
In addition, the 100B of bevel tool mechanism utilizes cell moving motor 90, is pre-configured in respect on the position of the 100A of bevel tool mechanism with the predetermined distance separation, and each 100A of bevel tool mechanism, 100B carry out cut-out simultaneously.
Cut off in the control second, use the bevel tool 102 and 103 (more lean on the rear if the end position deviation setting is oblique joint-cutting VFR than VFL, then use bevel tool 101 and 104) of the bevel tool 100B of mechanism.That is, CPU 81 forms oblique joint-cutting VFR, VFL by bevel tool 102 and 103 is risen after utilizing big presser feet feed mechanism 20 to make the leading section PFR angle of arrival cutter mechanism 100B of straight line stitching TR of cloth M, B.That is, oblique joint-cutting VFR and VFL be not because the end position unanimity on the X-direction of straight line joint-cutting S side forms so do not follow feed motion during this period.
In addition, the 100B of bevel tool mechanism utilizes cell moving motor 90, is in advance with respect on the position of the 100A of bevel tool mechanism with the predetermined distance separation, and each 100A of bevel tool mechanism, 100B carry out cut-out simultaneously, and it is identical that this point and first is cut off control.
(the center joint-cutting of filler rod forms control)
The center joint-cutting of filler rod forms control, utilizes the center joint-cutting that is stored among the ROM 82 to form control program 82d and carries out.That is, CPU 81 forms control program 82d by implementation center's joint-cutting and works as second control module.
Promptly, CPU 81 forms control program 82d by implementation center's joint-cutting, form at the angle joint-cutting and to judge in the control and select first to cut off after in controlling which control and second cut off, carry out following control, that is when selecting first to cut off control, be the end position that benchmark is determined the straight line joint-cutting, with the end of extended straight line stitching, when selecting second to cut off control, be the end position that benchmark is determined the straight line joint-cutting with the end of not extended straight line stitching.
Here, so-called " extending ", a side straight line stitching (being straight line stitching TR in Fig. 2,3) of representing relatively forwards to extend for the leading section side is represented a side straight line stitching (being straight line stitching TL in Fig. 2,3) that relatively rearward extends for the rearward end side.Here, former end side is that example describes.
As Figure 11, shown in Figure 12, use long and short two kind bevel tool respectively and carry out first and cut off control and second and cut off under the situation about controlling at the 100B of bevel tool mechanism, the prerequisite length X S of shearing length on the cloth direction of feed that to be the shearing length that formed by bevel tool 102 (long cutting knife) form at the length X L on the cloth direction of feed with by bevel tool 103 (short cutting knife) is poor, consistent with end position deviation CF (CF=XL-XS).Promptly, cut off in the control second, end PFR (with reference to Fig. 2) from extended straight line stitching, to the position of non-extension lateral deviation to the length X L of the shearing length that forms by bevel tool 102 on the cloth direction of feed, never the end PFL (with reference to Fig. 2) of the straight line stitching of Yan Shening beginning, to the position of non-extension lateral deviation to the length X S of the shearing length that forms by bevel tool 103 on the cloth direction of feed, all consistent with leading section position FE shown in Figure 12, cutting off under the situation of the corresponding and formation straight line joint-cutting of control with second, its leading section position FE can determine as benchmark with in the end of the end of extended straight line stitching and not extended straight line stitching any.
If cutting off control and second first cuts off under any situation of control, all the end PFR with extended straight line stitching is the end position that benchmark is determined the straight line stitching, then select switching to second and cut off under the situation (perhaps opposite situation) of control cutting off control, need the distance from the end of straight line stitching to the end position of straight line joint-cutting is reset to length X L (or opposite) from length X S with it from first.
But, form control program 82d by implementation center's joint-cutting, CPU 81 is a benchmark by the end PFR with extended straight line stitching TR when first cuts off control, end PFL with not extended straight line stitching TL when second cuts off control is a benchmark, thereby under any situation, all can determine the end position of straight line joint-cutting based on the length X S of the shearing length that forms by bevel tool 103 on the cloth direction of feed.Thus, switching first and second when cutting off control, can reduce again the working load that the range difference between the end PFL of the end PFR of straight line stitching TR and straight line stitching TL is set at length X L (or opposite) from length X S.And, the operator need be corresponding with the setting value of end position deviation CF (or RF), adjust bevel tool 102 (or bevel tool 104) around the angular adjustment of Z axle and point of a knife towards angle of inclination (θ 2), but under the situation of present embodiment, do not need to import the length X L corresponding and get final product, further reduce working load with the angle of inclination of changing (θ 2).
