The Eagles Groz-Beckert for a single-head and mnogolovochny embroidery - perfect embroidery on industrial embroidery machines.
In the area one - and a mnogogolovochny embroidery on modern embroidery machines there are no borders to creativity. In recent years considerably the amount of the materials used for embroidery increased.
The 3D embroidery, embroidery on skin and technical textiles, on multilayered materials and materials with special coverings is in many cases difficult conditions for work of an embroidery needle, especially with increase in speed of embroidery.
Groz-Beckert makes needles for embroidery on geometry and accuracy conforming to difficult requirements of the market:
- Optimum type of an embroidery;
- High functional confidence;
- Reduction of a break of needles;
- Reduction of a rupture of threads;
- Reduction of idle time of embroidery machines;
- High efficiency.
Needles for DBxK5 embroidery machines in various options
The original needle for one - and a mnogogolovochny machine embroidery was developed for modern high-performance cars.
When developing geometry of a needle the following items were taken into account:
- Decrease in admissions of stitches and rupture of thread.
- The maximum preservation (sparing the relation) thread and material.
- Sure formation of loops.
- Optimum form of an edge.

Stability of a needle for DBxK5 embroidery machines
Unambiguously the system of a needle DBxK5 has the best stability. Thanks to constructive even the standard needle of Groz-Beckert DBxK5 on degree of resistance to a deviation shows much higher rates, than other needles applied to embroidery.
SAN1 GEBEUR thanks to the constructive signs and the titan-nitridovomu gives to a covering the maximum protection against wear at the highest stability.
The design of a core of a needle of KK execution corresponds to a standard needle. Thanks to short degree of resistance to a deviation is much lower.
Needle edge options for DBxK5 embroidery
| Standard edge of RG and other options of an edge. In numerous tests on application of needles for embroidery the edge of RG proved to be on various materials as the best edge. Therefore it is accepted the Groz-Beckert company as a standard edge for embroidery needles. |
For specific application the following forms of an edge of needles for an embroidery are had on hand:
FG/SUK
FFG/SES
R
Other systems of needles for embroidery
Stability of a needle
The systems of needles specified here were made not only for embroidery. On application signs these needles first of all are intended for a machine seam.
Their stability and resistance to a deviation are specified in the chart and are comparable with DBxK5 options.
The known problems in application of embroidery needles and possible decisions.
Use of a needle for an embroidery on jersey
For a material damage exception, embroidery on jersey almost always demands application of needles with a round edge.
For thin jersey take a standard edge of RG (also FFG), and for jersey of large knitting — FG an edge.
Needle thickness also considerably influences possibility of damage of material in the course of an embroidery. Anyway, it is recommended to try various numbers of embroidery needles for obtaining desirable result.
| If the edge of a needle is very sharp or damaged — yarn of a loop will be calcinated and there will be a rupture of a loop. If the needle is thick — the loop can burst at excessive separation. |
| It is possible accurately, to process thin cloths without admission of stitches with a DBxK5 system needle. |
Use of an embroidery needle at an embroidery on woven products
At an embroidery on thin or thick woven materials, too big round edge or too thin size of a needle — will surely lead to problems at vyshivanii:nechetky drawings of an embroidery because of an uneven covering thread, the rupture of thread or even breaks of a needle — will be natural result.
At such embroidery the increased stability at the simultaneous sparing relation to material is demanded. These properties the system of needles DBxK5 in all sizes has.
Uneven drawing of an embroidery
| The needle bend because of the choice of very thin needle, or the choice of a needle with strongly rounded edge will yield result of the uneven drawing of an embroidery in the course of machine sewing. |
| When using DBxK5 No. 75 with an edge of RG we will receive on a cloth satisfactory result even on difficult sites of an embroidery. |
Use of a needle for embroidery machines on skin
At embroidery on skin the significant role is played by the choice of a form of an edge: both for drawing clearness, and for its quality. The cutting edge will not approach here. A cut of threads, perforation of skin and uneven piercing when changing the direction of an embroidery — will be result of application of a needle for industrial sewing machines with the cutting edge. For thin and average skin the embroidery needle with RG an edge well proved to be. For rough skin it is recommended to apply needles to embroidery machines with R or SD an edge.
As puncture force very big, a needle has to be stable. The system of a needle DBxK5 SAN1 GEBEDUR conforms to this requirement.
| When using of the cutting edge at an embroidery on skin there is a different section in the longitudinal and cross direction. At worst there can be even a cutting skin on an embroidery contour. |
| When using very stable needle of DBxK5 SAN1 No. 75 with RG edge — it is possible to receive a faultless embroidery on skin. The drawing uniform and contours are filled. |
3D embroidery
One of the highest requirements show to needles for three-dimensional embroidery.
For obtaining 3D effect it is necessary to enclose under an embroidery and to fix by adhesive substance so-called penotkan / foam rubber. Fixing of this laying causes the increased friction of a needle and thread. Besides, in the field of embroidery of the drawing cross seams where force of a puncture and force of a tension of thread are very various very often meet. Therefore the applied needle has to fulfill the following requirements:
- Reduction of force of a puncture and, as a result, the sparing relation to material.
- The increased stability of a needle promoting reduction of the admission of stitches, reduction of a break of needles and increase in accuracy of the embroidered drawing.
- Increase in resistance to wear, so — increase in service life of needles for the embroidery equipment.
Compliance to all these requirements was realized by means of change of a design not only at the standard DBxK5 system, but first of all at the DBxK5 SAN1 GEBEDUR system.
Removal of pro-masonry material of a penotkana
After embroidery on pro-masonry material, it has to be removed from the embroidered product. That is it is necessary to remove the penotkana remains accurately.
Result of three-dimensional embroidery
The desirable result at an embroidery of the 3D drawing will be achieved, with a certain accuracy of piercing if penotkan remains is covered with the embroidered thread and and damages of material will be absent. The uniform and beautiful drawing as result of three-dimensional embroidery by Groz-Beckert needles on the person.
