Abstract
A thread support means (27) traverses the rear side of needles (19, 21) in cooperation with a sewing machine main shaft and supports thread loops (11b, 13b) consecutive toward the needles from rows of a seam. When the needles penetrate through a thin fabric, the thread support means (27) prevents the thin fabric from being pushed down by the thread loops and sinking into the needle holes of a needle plate (29) together with the needles and causing distortion thereby. When the needles (19, 21) rise, the thread support means (27) slips out of the thread loops (11b, 13b), while the fabric advances by the length of one stitch, and the thread loops (11b, 13b) are absorbed into a newly formed stitch to be tightened appropriately, thereby forming a uniform seam without wrinkle.
Description
The present invention relates to the to sew method and apparatus of fabric, its stretching when forming seam can not cause producing torsional deformation in fabric.
When using interlock seam sewing machine, when double-stranded seam Sewing machines or similar equipment carried out making of fabric, if fabric is thin and soft, because the tension force of suture, perhaps fabric was absorbed in the pin hole of Sewing machines needle plate, and the seam tension tightens.When the needle penetration fabric, occur wrinkling along seam probably.
In interlock seam sewing machine, wrinkling in order to prevent this seam, attempt for example when sewing, to use a kind of conformal paper to be fitted on the thin fabric.
On the other hand, use interlocking seam sewing machine or double-stranded seam Sewing machines to form double-stranded seam, with crosspointer or three pins and a looper, when forming double-stranded seam, on fabric, need not the loam cake line, with crosspointer and three-way, perhaps (the United States Federal's seam type: 406 or 407) end face at fabric presents the multirow seam, and multirow seam and plug-in type lid line (kink take-up) is presented on the bottom surface of fabric for three pins and four lines.When forming such seam on thin fabric, multirow seam tegmentum line stretches mutually, and perhaps when the needle penetration fabric, fabric and pin are absorbed in the pin hole of needle plate together, bulge into ridge so the end face of fabric in the ranks often occur.Similar problem (the United States Federal's seam type for example: 309 or 311) also appears when constituting eyelet with crosspointer and three-way or three pins and four lines.
In order to address these problems, require technology very skilled, for example to adjust the tension force of line subtly, and will under the operating rate that reduces Sewing machines, sew carefully.
In addition, in the interlocking seam or double-stranded seam Sewing machines of crosspointer or three pins, do not adopt the top cover line,, promptly fabric is sent to successively, but must be accomplished between fabric, to form continuously and smoothly linear chain by operating Sewing machines continuously so that improve sewing efficiency.In this Sewing machines, all be at a fabric of sewing and after sending so far, pushed to down by pin to the terminal linear chain of sewing continuously, for forming next seam, pin to drop to needle plate below, when looper plays formed wire loop by means of needle holder, when rising from the bottom, it catches the linear chain of decline simultaneously, so feeding claw can not be sent linear chain.When not having fabric, right pin and left pin can not be kept its spacing between two row seams, can not process a uniform linear chain, are dropped to below the needle plate by its formed linear chain, thereby linear chain can not be sent by feeding claw, thus since these reasons can not continuously linear chain be pulled out.
For addressing these problems, Japan Patent prospectus 3-23887(United States Patent (USP) 5,027,728) provide a kind of Sewing machines, a thread-braking device is wherein arranged, protrusion forms the lower end of tongue in seam, from the pin hole of needle plate towards the fabric feedstock direction, and enter the fabric sewing end continuously from the linear chain that tongue stretches out, caught by thread brake, thereby preventing linear chain owing to the whereabouts of pin descends, formed linear chain is sent by the feeding claw that disposes along feedstock direction, thereby sends linear chain.
Main purpose of the present invention is to provide a kind of method and apparatus of the fabric of sewing, and especially has good outward appearance when the sewing flimsy material, does not produce wrinkle.
Another object of the present invention is on fabric, form continuously reliably linear chain, terminal until sewing.
The present invention is to provide a kind of single needle Sewing machines or multineedle sewing machine, it has the line bearing device, laterally strides across the traffic direction of fabric at the fabric discharge end of pin, with moving up and down harmoniously of pin.
When pin descended and form the next time sewing, the line bearing device advanced on the fabric at the discharge end of pin, the line bearing device continuous from the seam to the pin, accept also to support needlework, and when pin rises, get back.
When pin descended and penetrates fabric, the needlework ring from the seam to the pin was supported by the line bearing device, stoped fabric to be absorbed in the pin hole of needle plate, along with descending pin and needlework ring are pushed to the below.So fabric can not produce torsional deformation.When pin rose, the line bearing device was got back, so needlework along with the rise of pin is suitably tightened together, thereby form a clean and tidy seam.
The present invention is suitable for being applied in and has on the Sewing machines that spininess moves up and down most, comprises that collaborative pin forms singles' loop device of seam together, crosses in the direction of needle plate lower edge alignment pins, and comprises a fabric feed arrangement.
The line bearing device supports needlework between seam and pin, so its supports linear chain continuously up to the tail end of a fabric and the initiating terminal of next fabric, along with the descending motion of pin stops the sinking of linear chain, so linear chain is stretched smoothly.
These and other objects of the present invention can make ordinary skill be expressly understood more from the following description.
Fig. 1 is the stereogram of a kind of double-stranded seam Sewing machines of the present invention;
Fig. 2 is to use the seam stereogram of double-stranded seam Sewing machines sewing;
Fig. 3-the 7th forms the partial perspective view in the seam process of double-stranded seam when using double-stranded seam Sewing machines among Fig. 1, but wherein fabric and needle plate are not shown;
Fig. 8 is the partial perspective view that forms the linear chain process among Fig. 1 when using double-stranded seam Sewing machines.
Fig. 1 represents the Sewing machines of the United States Federal's seam 406 types for the double-stranded seam of formation, is made up of two needlework 11 and 13 and kink take-ups 15.Below the head 17a of sewing machine arm 17C one end, right pin 19 and left pin 21 moves up and down with machine spindle is collaborative, presser feet 23 is set and line bearing device 27,27 is horizontal on presser feet 23, is positioned at the discharge end (being the front of compressor arm 25) of pin 19,21.Adjust the teeter of line bearing device 27 and be in step with mutually, change its installation site according to the character of fabric and some sewing condition with the vertical motion of pin 19,21.
Sewing machines pedestal 17b comprises needle plate 29, and feeding grabs 31, and it moves up and down by the slit so that feeding claw on needle plate 29 with presser feet 23 cooperative motions, fabric is carried, and looper 35 is along the direction back and forth movement of pin 19,21 arrangements, with pin 19,21 co-operatings, form double-stranded seam.In the bottom surface of sewing machine arm 17C line tension adjuster 33 is set,, and kink take-up 15 is applied tension force so that two needlework 11 and 13 are applied tension force respectively.Adjuster 33 comprises that the line of a sewing usefulness is regulated composite set 33a and a line that constitutes linear chain is regulated composite set 33b.Perhaps line adjusting composite set is made of initiatively a conversion equipment (not shown), and it then is driven that another line is adjusted composite set.
In sewing operation, can make line adjust composite set 33a by means of conversion equipment and convert to initiatively, and with line adjust composite set 33b become driven, thereby start Sewing machines 17.
Fig. 3 to Fig. 7 represents to constitute the forming process of double-stranded seam as shown in Figure 2 with Sewing machines 17.Looper 35 grasps formed wire loop 11a, marches forward immediately behind the 13a, and pin 19 and 21 is carrying line 11,13 and descending, for forming next seam, meanwhile from wire loop 11a, 13a reaches pin 19 to line bearing device 27 at needlework 11,13, the 21 former pins 19 that traverse, 21(Fig. 3, back Fig. 4).When the length that makes a seam of fabric (not shown) feeding with feeding claw 31 and pin 19,21 pass fabric, because line bearing device 27(sees Fig. 4,5) supporting, wire loop 11b, 13b just are formed on the top surface of fabric.
When pin 19,21 penetrate fabric, through by looper 35 formed triangles, arrive kink take-up 15 and wire loop 11a, 13a(Fig. 5) preceding inlet side, and when dropping to bottom position, looper 35 retreats from front end, and from wire loop 11a, the 13a withdrawal, arrive the backspace end, line bearing device 27 supports wire loop 11b, and 13b moves forward and arrive preceding inlet side (Fig. 6).When pin 19,21 when descending in this way, wire loop 11b, 13b are in the state that is supported by line bearing device 27, so the end face of fabric is not directly used wire loop 11b, the 13b pressurized, so when pin 19,21 penetrates fabric, wire loop 11b, 13b can not push fabric in the hole of needle plate, so fabric can be by the needlework torsional deformation.
When pin 19,21 when bottom position rises the wire loop that forms is again held up because looper 35 advances, this moment, the line bearing device 27 retreated from wire loop 11b, the 13b slippage is come out.When pin 19,21 rises and fabric when being fed forward the length of a seam, wire loop 11b, 13b is taken in the seam that forms again, and is tightened up and is stretched on the fabric as the crow flies, so constitute one not with the smooth joint of wrinkle.(see figure 7)
Behind the sewing fabric, form when being connected in the linear chain of seam end successively, by means of conversion equipment, line adjusting device 33a is converted to driven, and line adjusting device 33b converted to initiatively.When line pin 11,13 was supported on presser feet 23 top (as shown in Figure 8) by line bearing device 27, formed linear chain can not descend.When the tension force of right needlework 11 has been turned down, and the tension force of kink take-up 15 is high, for example, by means of line adjusting device 33b, the wire loop 11a of right needlework 11 is pulled to the wire loop 13a of left needlework 13 with kink take-up 15, together be placed in the linear chain by right and the formed wire loop of left needlework, and it is sent smoothly.For linear chain is sent reliably, a feeding claw with feeding claw 31 same types can be installed, so that will send corresponding to the fabric of presser feet 23 back locations.
Line bearing device in the above-mentioned concrete device can stop because the formed wrinkling or ripple of mutual stretching of seam row.So the line bearing device is arranged on the same height of presser feet or above presser feet, so that the clamping linear chain, if but only plan the clamping linear chain, supporter can be arranged on the top of needle plate or followingly all can.
Above-mentioned concrete device relates to the double-stranded seam Sewing machines with crosspointer, be to have a same line bearing device of use in single needle or the three-needle frame a kind of, perhaps formed wrinkle of mutual stretching or the ripple owing to the seam row can prevent in interlocking seam sewing machine or other Sewing machines, and in having the Sewing machines of looper, can form linear chain reliably.
