The rod for the formation of relief on fabric

 

(57) Abstract:

The invention relates to structures of rods that allow you to create Terry relief on the fabric. The device consists of a shaft mounted in the needle bar of the sewing machine, with grooves in the bottom of the working part of the rod is dulling with the tabs, the device has tier arbitrary cut. The upper part of the rod goes into the flask, which ends with end. 5 Il.

The invention relates to structures rods.

A known design of a sewing machine needle - needle singer, consisting of a rod, including utonchennoy part, turning into the tip, bulb, culminating in the end. In the forefront is the eye, which serves for the filling threads.

The disadvantage of it is that it can only function asiania tissues without changing its elevation.

Known also design degree for sewing machines. The needle contains a rod with grooves, including utonchennoy part, turning into the edge of the eye, flask, followed by end [1] .

The degree allows you to get the relief of the fabric, but not the Terry thread.

The aim of the invention is the expansion of technological POS of the C sewing machine needles, installed and fixed in the needle holder sewing machine, consists of a stud with big and small riffles and bulb, culminating in the end, on the bottom of the working part which is formed dullness in the form located at an angle to the longitudinal axis of a core area with a roughness corresponding to the 5th-6th grade purity, on the surface of which two protrusions, the height of one 0.3-0.7 mm, and the smaller of 0.1-0.4 mm, between which the cavity equal to 0.2-0.5 mm, and adjacent to the blunt part of the region of the cylindrical surface of the rod is formed of one row (row) random faces (cut), the height of which is equal within 0.5-0.8 mm and roughness 7-8 grade purity, using rods, the diameter of which is included in bespredelnyy diameter grounds, within 0.6-1.5 mm

The novelty of the proposed design is that the design is made up of sewing machine needles, installed and fixed in the needle holder sewing machine, installed and fixed in the needle holder sewing machine, consists of a stud with big and small riffles and bulb, culminating in the end, on the bottom of the working part which is formed dullness in the form located at an angle to the longitudinal axis CTE is one of 0.3-0.7 mm, and smaller 0.1-0.4 mm, between which the cavity equal to 0.2-0.5 mm, and adjacent to the blunt part of the region of the cylindrical surface of the rod is formed of one row (row) random faces (cut) whose height is in the range 0.5-0.8 mm and roughness 7-8 grade purity, using rods, the diameter of which is included in bespredelnyy diameter grounds, within 0.6-1.5 mm

These distinctive characteristics are significant, as in the studied sources of patent technical information signs, identical and equivalent, are not detected.

In Fig. 1-4 presents the design of the rod; Fig. 5 (a-g) - views Terry relief.

In Fig. 4 - closeup shows a graphical image of blunt ground at an angle to the longitudinal axis of the rod intertwined with tier arbitrary cut located on the bottom of the working part of the rod, the surface of which is rough-tenacious, proposed design. As can be seen from Fig. 4, in the axial cross section is trapezoidal form.

Type rough-retentive surface - random (Yuriev Century. And. Types of areas of surfaces, Guide designer-mechanical engineer, so 1, I'm part of the rod ends dulling with the projections 3, there is a tier 4 arbitrary cut. The upper part of the rod goes into the bulb 5, which ends with the end face 6.

Based on the rods formed from needle sewing machines N 60 - N 150, as bespredelnyy values of the diameters of the rods is impossible to experiment on only one core due to their cylindrical shape in contrast to the cone, where bespredelnyy values of the diameters of the sites you can experiment on the same sample limit non needles.

By mechanical removal of the nodes sewing machines N 60-N 150 is removed at the level of the eye of a needle so that the remaining two tabs (the tabs from the tab remaining after removal of the tip of the needle of the sewing machine, the height of the abalone 1.5 mm), one smaller one on the site, located at an angle to the longitudinal axis of the rod, adjacent to the blunt part of the region of the cylindrical surface of the rod is formed tier (row) arbitrary cut with rough-retentive surface. Using the rods, the diameter of which is included in bespredelnyy diameter areas within 0.6-1.5 mm All the above parameters are optimal for the creation of Terry terrain with a high degree of performance of, the best are the following parameters for the operation of the lower end of the rod: blunt Playground, located at an angle to the longitudinal axis of the rod, with two protrusions on its surface, the height of one 0.3-0.7 mm, and the smaller of 0.1-0.4 mm, tier arbitrary cut whose height is in the range 0.5-0.8 mm, the roughness of the working lower part of the rod, corresponding to the 5th-8th grade purity.

Using the geometric relationship of the values that define the relationship between d-diameter of the rod, h-height of an arbitrary cut.

The data obtained optimal parameters of the working end of the rod, and their values are given in table. 1 (used model sewing machine needles 0277-33, performance rod 02).

With regard to the issue of roughness with the characteristic in the numerical data, in accordance with the L1you can get Terry relief of various drawing and versiondatabase different lengths from 1.5 mm

A rod formed from a needle of the sewing machine and mounted in the needle holder, works as follows.

When pressed (and piercing) lower rough work-gripping end of the rod to the surface of cotton fabric to get Terry relief is

the tension of the yarns of the fabric on the front and back surfaces in all zones in the direction of the puncture site, located from the site of puncture and perforation lines;

the tension of the yarns of the fabric on the cotton material passing into priobresti tightening (warp and weft), which is maintained and enhanced at the time of puncture and stored after a puncture tissue;

on the original side of the material except for the bulge forming in places puncture formed versionrange, up to 1.5 mm pile length, in combination with koleobrazovaniya threads of the fabric (warp and weft). The pile is not maintained even if the pull of the villi.

So, under the influence of the lower working end of the rod, which is arbitrary cut intertwined with the two tabs on the dullness is formed is iceway and lower wrong).

Varieties of figure, obtained during the formation of Terry relief cotton fabric shown in Fig. 5 (a-d).

5(a) is a drawing Terry relief from the front side, alternating straight and wavy lines puncture cotton fabric.

5(b) - wrong side of the material, which is formed pile up to 1.5 mm in combination with the ringing of the threads of the fabric (warp and weft).

5(b) - front Terry relief lint-free cloth. The line of puncture is directed parallel to the warp (weft).

5(g) - versionrange on the wrong side is sparse in comparison with Fig. 5A.

Get Terry relief using offer web design, formed by sewing machine needles, can be used in light industry in the manufacture of various garments and in combination with the finishing of other materials.

Thus, the proposed design of the core allows for the piercing of cotton fabric to make two functions - to create relief and form a pile in the form of breakage of the threads of the fabric in places puncture in combination with nikolyamaniu that allows you to extend assorties EDUCATION RELIEF ON the FABRIC , installed and fixed in the needle holder sewing machine having two groove and the flask is terminated by an end face, characterized in that, with the aim of expanding the technological capabilities by obtaining Terry relief on the bottom of the working part of the rod is formed dullness in the form of an angled longitudinal axis of a core area with a roughness corresponding to 5 to 6 classes of cleanliness on the surface of which has two tabs, the height of one of which is from 0.3 to 0.7, and the other 0.1 - 0.4 mm, and between the projections formed hollow, equal to 0.2 - 0.5 mm, and adjacent to the dulling of the surface of the rod has a single tier of cutting, the height of which is equal to 0.5 - 0.8 mm, and the surface roughness corresponds to 7 - 8 classes of cleanliness, the diameter of the rod is 0.6 - 1.5 mm
