Description
Technical field
The present invention relates to a kind of method of using Sewing machines to form seam, particularly relate to, for example become ball or the like with leather sewn by sewing up the method that thick material forms seam, or (making) tent, or (making) canvas; Method is that the front of two block of material is faced with each other, and then the side seam of material is lumped together, and then the material that is stitched together is launched, so that joining edge is stashed.
Background technology
In the seat or the seat in the household in motions such as Association football in employed ball or the vehicle, each seam is all being born very big load, and load will make suture loosening, thereby sewn seams is split.In order to prevent this cracking, each ball is all made excessively by hand by two-pass and is formed; Yet the efficient of this manual suture is very low.In addition, in the manufacturing process of seat and household seat, also there is not special method to prevent gaping of joints.
When materials such as use stitching sewing machine leather, tent, above-mentioned material, face with each other the front of two block of material is superimposed together, and uses the edge of lockstitch machine suture material then.In use, launch sewing up good material, so that hide joining edge.
The suture strength of sutured portion depends on: the tensile strength of (1) every needlework (promptly reaching the standard grade) and loop wire (promptly rolling off the production line), (2) frictional force on each toe-in between needlework and the loop wire, (3) frictional force between needlework, loop wire and upper strata, subsurface material (or cloth).Therefore, because the suture strength of sutured portion all is added on the single line, thereby suture strength depends on the intensity of single line.In addition, when the material of being sewed up was unfolded, needlework and loop wire can become flexible, and each toe-in can be out of shape, and upper layer of material and subsurface material are compressed owing to needlework and loop wire.
According to this phenomenon, when sewing up good material (or cloth) expansion, the contact-making surface between upper layer of material and the subsurface material is opened, and the result makes because needlework and loop wire or toe-in are exposed on the surface of material, thereby causes product quality to descend.
In order to address the above problem, a kind of stitching process has as shown in figure 10 been proposed, wherein use the lockstitch machine by (1) upper strata cloth F1 and lower layer mix feeding F2 march forward to the time form two stitch forward and (2) form a stitch (or back stitching stitch) backward, thereby the formation single stitch repeats this process and just can process a sewn seams.
The seam that forms according to top method comprises a slip-knot stitch H who is used for needlework A knotting, and slip-knot stitch H is formed on backward that stitch becomes the place of stitch forward.In addition, cloth is stitched together by three needlework A and three loop wire B.Therefore, increased the extruding force between the cloth, seam frequency loosening or cracking has reduced.Yet, include reverse stitch owing to make the process of seam; Therefore, operator's tailoring cloth also is not easy, and can feel under the weather.

The specific embodiment
Below with reference to the description of drawings embodiments of the invention.First embodiment
Below see figures.1.and.2 first embodiment of seam formation method of the present invention is described.
In the present embodiment, seam is to use lockstitch to make by two vertical pins.Sewing machines used herein is to obtain by improving traditional two-needle sewing machine, in the Sewing machines after improvement, along pin and the opposed facing direction of shuttle hook perpendicular to they directions in traditional Sewing machines.That is to say, in the Sewing machines of present embodiment, arranging shuttle hook C1, pin D1, pin D2 around rotation counterclockwise and the shuttle hook C2 that rotates around counter clockwise direction along the direction of feed of cloth (or material).
In operation, at first, it is identical to use amount of feeding setting device (not drawing) that the amount of feeding of the amount of feeding of the cloth at pin D1 place (near the operator) and the cloth at pin D2 place is set at, thereby utilizes pin accurately to form stitch independently of one another on corresponding position.
After the above-mentioned amount of feeding is set, start Sewing machines, just can process stitch shown in Figure 1 continuously.Below will make an explanation to these stitch.Here, in every width of cloth figure of these stitch of explanation, in the describing mode to needlework and loop wire, the major part of line does not contact with lower layer mix feeding with the upper strata cloth; And in practical situation, these lines are tightly to be locked on each stitch, thereby make needlework and loop wire closely contact with cloth up and down.
When Sewing machines is worked, cloth F1 and F2 move forward, form complete stitch P continuously by shuttle hook C1 and pin D1 (promptly by needlework A1 and loop wire B1), simultaneously, form slip-knot stitch H continuously by shuttle hook C2 and pin D2 (promptly by needlework A2 and loop wire B2), at this,, the relation of the position between shuttle hook C2 and the pin D2 produces the toe-in that is twisted together owing to making slip-knot stitch H.In said process, each complete stitch P that is produced by needlework A1 and loop wire B1 is formed on each the slip-knot stitch H that is produced by needlework A2 and loop wire B2 and goes up (promptly, be formed on the same stitch points, that is to say and be formed on the identical knotting point), make complete stitch P after slip-knot stitch H and with it at a distance of a pitch.Therefore, on each stitch points of seam, complete stitch P and slip-knot stitch H are overlapped.
In the seam that forms according to above process, on each knotting point, all can form complete stitch P and slip-knot stitch H with very big knot strength.In addition, between adjacent knotting point, stretch, and two loop wires are crossed lower layer mix feeding and are stretched between adjacent knotting point because two needlework are crossed the upper strata cloth; So, between needlework and the upper strata cloth the frictional force at contact-making surface place and the frictional force at the contact-making surface place between loop wire and the lower layer mix feeding all can be very big (that is, the compressive strength that is added on the cloth up and down is very big).Therefore, when opening cloth after finishing the making of above-mentioned seam, seam can not become flexible and be ftractureed.
In addition, because the rotary speed of Sewing machines (that is feed speed) consistent with sewing velocity (that is, equating); So the operator can not feel under the weather.Also have, can be easy to realize method in the present embodiment by the traditional two-needle sewing machine of simple modifications, wherein pin and the opposed facing direction of shuttle hook and its direction in traditional Sewing machines are perpendicular.Second embodiment
Following second embodiment that seam formation method of the present invention is described with reference to Fig. 3 and Fig. 4.
In the present embodiment, seam is to use lockstitch to make by two vertical pins, and two pins are backcrossed on direction of feed for shifting one's position.
The Sewing machines of present embodiment is to obtain by improving traditional two-needle sewing machine, in the Sewing machines after improvement, pin and the opposed facing direction of shuttle hook and its direction in traditional Sewing machines are perpendicular, and the needle bar that two pins are installed is put upside down 180 degree on each stitch, thereby realizes moving back and forth.That is to say, in the Sewing machines of present embodiment, put upside down 180 degree on each stitch in case two pin D1 that realize moving back and forth and D2 between shuttle hook C1 and C2, wherein shuttle hook C1 and C2 be around rotating counterclockwise, and the shuttle hook is to arrange along the direction of feed of cloth.
In operation, at first, consider the interval between two pins, (that is, close operator) the cloth amount of feeding and the cloth amount of feeding at pin D2 place are so that accurately form stitch on correspondence position to use amount of feeding setting device (not drawing) to set pin D1 place.
After the above-mentioned amount of feeding is set, start Sewing machines, just can process stitch shown in Figure 3 continuously.Below will make an explanation to these stitch.
That is to say, form stitch when between two kinds of patterns, alternately switching the position relation between two pins and the two shuttle hooks.
More particularly, in needlework one, just when catching, needlework A1 forms complete stitch P with loop wire B1 by shuttle hook C1 to needlework A1 by shuttle hook C1 (that is, near operator shuttle hook); Simultaneously, another root in the needlework, just needlework A2 is caught by shuttle hook C2 (that is, apart from operator's shuttle hook far away), makes needlework A2 just form slip-knot stitch H with loop wire B2 by shuttle hook C2.
When the cloth pitch of advancing forward, and the position of pin is when exchanging mutually, and needlework A1 just forms a slip-knot stitch H with loop wire B2 by shuttle hook C2, and has formed complete stitch P on the cloth of this position before this; Simultaneously, another root needlework A2 forms complete stitch P with loop wire B1 by shuttle hook C1.Therefore, in the seam that produces, same pin formed complete stitch P and slip-knot stitch H on same knotting point, thereby processing effect is similar to the processing effect that adopts reverse sewing method to obtain.
In the seam of processing as stated above, on each stitch, all can form reverse stitch, two needlework are crossed the upper strata cloth and are stretched between adjacent toe-in, and two loop wires are crossed lower layer mix feeding and are stretched between adjacent toe-in.Therefore, the frictional force of the frictional force of the contact-making surface between needlework and the upper strata cloth and the contact-making surface between loop wire and the lower layer mix feeding all can be very big.Therefore, when opening cloth after finishing the making of above-mentioned seam, seam can not become flexible and be ftractureed.
In addition, because the rotary speed of Sewing machines (being exactly feed speed) equate with sewing velocity; So the operator can not feel under the weather.Also have, the method in the present embodiment can be easy to realize that wherein pin and the opposed facing direction of shuttle hook and its direction in traditional Sewing machines are perpendicular by the traditional two-needle sewing machine of simple modifications; And pin moves reciprocatingly, so as on each stitch pin out of position 180 the degree.The 3rd embodiment
Following the 3rd embodiment that seam formation method of the present invention is described with reference to Fig. 4 and Fig. 5.
In the present embodiment, seam also is to use lockstitch to make by two vertical pins, and two pins are backcrossed on direction of feed for shifting one's position.
The Sewing machines of present embodiment is to obtain by the Sewing machines that improves second embodiment shown in Fig. 4, and this Sewing machines is located all feed-disabling motions at per two stitch (by the stitch of each pin formation).That is to say that in the Sewing machines of present embodiment, put upside down 180 degree at each stitch place to realize reciprocating two pin D1 and D2 all between the shuttle hook C1 and C2 that counterclockwise rotate, at this, the shuttle hook is arranged along the direction of feed of cloth; And all feed-disabling moves so that form next stitch under the situation of not feeding cloth at per two stitch places.
In operation, at first, consider the interval between two pins, (that is, close operator) the cloth amount of feeding and the cloth amount of feeding at pin D2 place are so that accurately form stitch on correspondence position to use amount of feeding setting device (not drawing) to set pin D1 place.
After the above-mentioned setting that realizes the amount of feeding, start Sewing machines, just can process stitch shown in Figure 5 continuously.Below will make an explanation to these stitch.
That is to say, between two kinds of patterns, alternately switch in the position relation between two pins and the two shuttle hooks, formed stitch.
More particularly, in needlework one, just when catching, needlework A1 forms a complete stitch P with loop wire B1 by shuttle hook C1 to needlework A1 by shuttle hook C1 (that is, near operator's shuttle hook); Simultaneously, another root needlework, just needlework A2 is caught by shuttle hook C2 (that is, apart from operator's shuttle hook far away), makes needlework A2 produce a slip-knot stitch H with loop wire B2 by shuttle hook C2.
When the cloth pitch of advancing forward, and the position of pin is when exchanging mutually, and needlework A1 forms a slip-knot stitch H with loop wire B2 by shuttle hook C2, and has formed complete stitch P on the cloth of same position before this; Simultaneously, another root needlework A2 forms a complete stitch P with loop wire B1 by shuttle hook C1.
When the cloth stitch that advances forward again, and the position of pin is when exchanging mutually, and needlework A1 forms a complete stitch P with loop wire B1 by shuttle hook C1; Simultaneously, another root needlework A2 forms a slip-knot stitch H with loop wire B2 by shuttle hook C2, and formed a complete stitch P on the same position of cloth.
When feed motion stops, during pin out of position, needlework A1 forms slip-knot stitch H with loop wire B2 by shuttle hook C2, and needlework A2 and loop wire B2 have formed a slip-knot stitch H on the position before being right after this stitch; Another root needlework A2 forms a complete stitch P with loop wire B1 by shuttle hook C1, and needlework A1 and loop wire B1 have formed a complete stitch P on the position before being right after this stitch.
Therefore, in the seam that processes, on each knotting point, formed four toe-ins, and on each knotting point, formed complete stitch P and slip-knot stitch H, so processing effect is similar to the processing effect of the reverse sewing method of employing by same pin.
In the seam that processes as stated above, there are four toe-ins at the place at same knotting point, and has all formed reverse stitch on each point.In addition, cross the upper strata cloth and between adjacent knotting point, launched four needlework, between adjacent knotting point, launched two loop wires and cross lower layer mix feeding.Therefore, the frictional force of the frictional force of the contact-making surface between needlework and the upper strata cloth and the contact-making surface between loop wire and the lower layer mix feeding all can be very big.Therefore, when opening cloth after finishing the making of above-mentioned seam, seam can not become flexible and be ftractureed.
In the present embodiment, sewing velocity is lower than the rotary speed (that is feed speed) of Sewing machines; Yet, because do not need to change direction of feed, so the operator just can not feel ill.Also have, the method in the present embodiment can realize by improving traditional two-needle sewing machine, improve as follows: (1) wherein pin and the opposed facing direction of shuttle hook and its direction in traditional Sewing machines is perpendicular; (2) pin moves reciprocatingly, so as on each stitch pin out of position 180 the degree; (3) at per two stitch places, feed motion stops.The 4th embodiment
