A kind of flap drop sewing manufacture craft
Technical field
The present invention relates to the sport footwear technical field, specifically a kind of flap drop sewing manufacture craft.
Background technology
One is positioned at the instep portion of shoes flap, and flap can cover and protect foot.Flap also can prevent the living friction of shoestring and human hair combing waste.In traditional flap preparation method, concordant in flap face and the flap, thickness is thicker, with the contacting of instep in the frictional force that produces big, comfort level is poor.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of utilization layer method that do not stagger to make the flap reduced thickness form drop, make in instep and the flap between the flap drop sewing manufacture craft that contacts of softness.
The technical solution adopted in the present invention is such: a kind of flap drop sewing manufacture craft may further comprise the steps:
1, select for use in the flap that upper end radian width matches and the flap flooring, the upper end goes out 3-5mm than flap face length in the flap, and the lower end goes out 7-9mm than flap face length in the flap; 2, the reverse side car closes in flap face and the flap, concordant car to two endmarker of the upper end radian point place in flap face and flap, and 3 pins are stitched in start-stop, 1 inch 9-10 pin of back gauge 2-4mm needle gage, the corner circle aligns along mid point; 3, with slightly extremely positive in the flap to the 2-4mm that turns up; 4, the upper end grows the suitable flap face of 3-5mm of flap face and the radian sewing in the flap in the flap, closes by the 2-4mm back gauge car that turns up and seals, and 3 pins are stitched in start-stop, and needle gage is located the 8-9 pin for 1 inch; 5,5-7mm establishes at the place pin mark and is positioned on the vamp below the flap face, adds the 3-5mm that the flap borough chief goes out again, meets a common 8-12mm.
Material in the described flap is the compound vacuole silk floss of weaving cotton cloth.
By adopting the aforementioned techniques scheme, the invention has the beneficial effects as follows: the present invention forms drop by the application layer flap lower end reduced thickness that method will be fixed on the vamp that do not stagger, and the elastic characteristic of material in the flap, soft contact nature is fitted between making in instep and the flap, thereby has promoted comfort level.
Description of drawings
Fig. 1 is the flap structural representation of this manufacture craft;
Fig. 2 is fixed on structural representation on the vamp for flap.
The specific embodiment
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, select for use earlier in the flap that upper end radian width matches 1 with flap face 2,1 upper end grows 4mm than flap face 2 in the flap, 1 lower end grows 8mm than flap face 2 in the flap, first then reverse side car closes in flap face 2 and the flap 1,1 concordant car to the two endmarker point of upper end radian place in flap face 2 and flap, 3 pins are stitched in start-stop, 1 inch 10 pin of back gauge 3mm needle gage, corner circle aligns along mid point, again with in the flap 1 slightly to the 3mm that turns up to positive, the 4mm that 1 upper end grows flap face 2 in the flap is along 1 radian sewing in flap face 2 and the flap, close by the 3mm back gauge car that turns up and to seal, 3 pins are stitched in start-stop, 1 inch 8 pin of needle gage, as shown in Figure 2,6mm establishes at the place pin mark 3 and is positioned on the vamp below flap face 2 at last, adds 1 4mm that grows in the flap again, meets position 5 10mm altogether.
Embodiment 2
As shown in Figure 1, select for use earlier in the flap that upper end radian width matches 1 with flap face 2,1 upper end grows 3mm than flap face 2 in the flap, 1 lower end grows 7mm than flap face 2 in the flap, first then reverse side car closes in flap face 2 and the flap 1,1 concordant car to the two endmarker point of upper end radian place in flap face 2 and flap, 3 pins are stitched in start-stop, 1 inch 9 pin of back gauge 2mm needle gage, corner circle aligns along mid point, again with in the flap 1 slightly to the 3mm that turns up to positive, the 3mm that 1 upper end grows flap face 2 in the flap is along 1 radian sewing in flap face 2 and the flap, close by the 3mm back gauge car that turns up and to seal, 3 pins are stitched in start-stop, 1 inch 9 pin of needle gage, as shown in Figure 2,5mm establishes at the place pin mark 3 and is positioned on the vamp below flap face 2 at last, adds 1 3mm that grows in the flap again, meets position 5 8mm altogether.
More than show and described basic principle of the present invention and principal character and advantage thereof; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent method thereof.
