The invention is capable of increasing the production efficiency and the product quality.
Description
Technical field
The present invention relates to a kind of courage cover that is used for the ball game utensil, specifically a kind of ball full circle knitting liner sleeve.
Background technology
The courage cover is ball game utensil indispensable link when making, from last century so far, the used courage of ball game utensil cover adopts shuttle-woven fabric splicing or the meticulous production of wire winding always, and roughly process is: raw fibre, spinning, warping, wear palm fibre, weave, arrangement behind the lining, typing, gluing are compound, cutting, stitching splicing, epidermis decoration etc.
In existing ball making process, adopt technologies such as bladders, courage cover shuttle-woven fabric coating, splicing and the outer coiling of courage always, take a lot of work and time-consuming, and quality and circularity is instability all.
Summary of the invention
The objective of the invention is to design a kind of ball full circle knitting liner sleeve, with improve production efficiency and product quality.
According to provided by the invention be exactly scheme, ball full circle knitting liner sleeve is characterized in that: described courage cover is to be woven into spheroidal with yarn monoblock type on circular knitting machine; Near the equator of courage cover, form the flat pin district of an annular;
In the narrowing district of shrinking gradually that forms an annular with respect to the subarctic side in flat pin district, in the widening district that forms an annular of amplifying gradually with respect to flat pin district near a side in the South Pole; Form the narrowing point in the arctic of courage cover, formed pin mark, put densely covered fine mesh at courage in the South Pole of courage cover.
Described yarn comprises T/C83/17, T/C85/15, T/C50S/3 strand, T/C32S/2 strand or T/C16S/2 strand.
Weave the method for ball full circle knitting liner sleeve, it is characterized in that:
On circular knitting machine, form pin mark with yarn earlier, begun knitting widening district then;
When knitting widening district, begin widening gradually from pin mark, during widening, the circumferencial direction that overlaps along courage selects 16～22 Along ents as the widening point; Corresponding to each widening point, every knitting 2～4 latitudes are put two pins, knit 76～100 latitudes altogether, form the widening district;
Follow knitting flat pin district, when weaving, it is knitting to utilize flat pin to carry out, and knits 99～163 latitudes altogether, forms flat pin district; Annotate: flat pin district need not to narrow, is to utilize common retractility of knit fabric and resilience.Because the strand of twisting is used for this courage cover, the knit fabric of this courage body is had more can charging into and hold round naturally with bladders gas with the knit fabric in plasticity, flat pin district.
Knitting then narrowing district, during narrowing, the circumferencial direction that overlaps along courage selects 16～22 Along ents as the narrowing point; Corresponding to each narrowing point, every knitting 2～4 latitude two-needle narrowings are knitted 76～100 latitudes altogether, form the narrowing district;
When knitting narrowing district, should reserve 50～70 millimeters the courage running-on that is used to put into bladders at the end in narrowing district;
Weave the narrowing point at last, the courage running-on is drawn in.
For vollyball,, respectively knit 74～78 latitudes in widening district and narrowing district.
For football,, respectively knit 84～88 latitudes in widening district and narrowing district.
For basketball,, respectively knit 96～100 latitudes in widening district and narrowing district.
Advantage of the present invention is: compare with traditional production process, can omit warping, wear palm fibre, put steps such as typing, cutting, splicing in order behind the lining, owing to do not need cutting and splicing, therefore can take about 15% by conservation.Labour cost nearly 50 percent.
Description of drawings
Fig. 1 is the schematic diagram of courage cover.
The specific embodiment
As shown in the figure: described courage cover is to be woven into spheroidal with yarn monoblock type on circular knitting machine; Near the equator of courage cover, form the flat pin district a of an annular;
At the narrowing district b that shrinks gradually that forms an annular with respect to the subarctic side of flat pin district a, at the widening district d that forms an annular of amplifying gradually with respect to flat pin district a near a side in the South Pole; Form narrowing point 2 in the arctic of courage cover, formed pin mark 1, put the flat dial material of the knit product formed fine mesh 3 in knitting process of gathering at courage in the South Pole of courage cover.
Described yarn comprises T/C83/17, T/C85/15, T/C50S/3 strand, T/C32S/2 strand or T/C16S/2 strand.
Weave the method for described ball full circle knitting liner sleeve, it is characterized in that:
On circular knitting machine, form pin mark 1 with yarn earlier, begun knitting widening district d then;
When knitting widening district d, begin widening gradually from pin mark, during widening, the circumferencial direction that overlaps along courage selects 16～22 Along ents as the widening point; Corresponding to each widening point, every knitting 2～4 latitudes are put two pins, knit 76～100 latitudes altogether, form widening district d; Can weave by vollyball 76 latitudes, football 86 latitudes, basketball 98 latitudes in the widening district.
In the joint portion of playing pin mark 1 and widening district d an enhancement region c can be set, so-called enhancement region c is meant the density of the knitting density in this zone greater than the other parts of widening district d, and purpose is in order to prevent the explosion after inflation of position, c place, enhancement region.Enhancement region c can weave 4～8 latitudes, should weave according to the mode that every knitting 2～4 latitudes are put two pins equally.
Follow knitting flat pin district a, when weaving, it is knitting to utilize flat pin to carry out, and knits 99～163 latitudes altogether, forms flat pin district a; Can weave required latitude number by required spheroid size for flat pin district a, for vollyball, the pin number that is approximately 102 ± 3 latitudes, a girth is 204 ± 5 pins; For football, the pin number that is approximately 120 ± 3 latitudes, a girth is 408 ± 5 pins; For basketball, be approximately 160 ± 3 latitudes, pin numerical digit 440 ± 5 pins of a girth; Annotate: flat pin district need not narrowing, is to utilize flat pin.Retractility that knit fabric is common and resilience.Because the strand of twisting is used for this courage cover, the knit fabric of this courage body is had more can charging into and hold round naturally with bladders gas with the knit fabric in plasticity, flat pin district.
Knitting then narrowing district b, during narrowing, the circumferencial direction that overlaps along courage selects 16～22 Along ents as the narrowing point; Corresponding to each narrowing point, every knitting 2～4 latitude two-needle narrowings are knitted 76～100 latitudes altogether, form narrowing district b; When actual weaving, the district can weave by vollyball 76 latitudes, football 86 latitudes, basketball 98 latitudes in narrowing;
When knitting narrowing district b, should reserve 50～70 millimeters the courage running-on that is used to put into bladders at the end of narrowing district b;
Weave narrowing point 2 at last, described courage running-on is drawn in.
At last after bladders being put into the semi-finished product courage cover of the above-mentioned narrowing district b that has formed, by 16-22 Along ent braiding narrowing point 2 of choosing in the sixth of the twelve Earthly Branches.Receive the technology of two pins and finish by knitting two to four latitudes until closing in.
After utilizing the described courage cover of the application, when the system ball, as long as put the described courage cover of the application outside bladders, the back of closing up (promptly forming narrowing district b) is just inflatable; For football, the disposable conventional air pressure that pours is 0.4～0.6bar, and test is pressed and is 1.2bar, and the diameter of ball is 210.5～210.9mm; For vollyball, can charge into conventional air pressure 0.2～0.4bar, measuring air pressure 1.0bar, diameter 200.2～210mm; Gluing system ball then, such production process is compared with traditional production process, can save for 50 percent artificial and time, can also save 15% raw materials for production.
