Needles for single and multihead embroidery

 With todays machines in the field of single and multihead embroidery there is no limit to creativity. This is also the reason why during the past years the variety of different embroidery materials has increased rapidly.

Especially three-dimensional embroidery, embroidery on leather and technical textiles with different layers of material and coatings, combined with high machine speeds, is in many cases an extreme challenge for the embroidery machine needle.

In design and precision Groz-Beckert embroidery machine needles have adopted the requirements of the market.

Market requirements are:

Optimum embroidery appearance

High functional safety

Reduced needle breakage

Reduced thread breakage

reduced machine downtime

High production efficiency 


THE DB X K5 AND ITS SPECIAL FEATURES

Variations of the DB x K5

The original needle for single- and multihead embroidery

The needle system DB x K5 was especially developed for the use in modern high performance machines. During research and development the following points had to be considered:

 

Reduction of skipped stitches and thread breakage

Maximum protection of thread and material

Safe thread loop pick up

Best universal point style

Eliminate looping

Optimum stitch

 

 

The features and applications of the DB x K5

Shank length

Point style

Coating

Stability comparison of the standard DB x K5 and its variations

Essentially the needle system DB x K5 has the highest stabillity. The bending resistance of the standard needle is higher than any of the other needle systems used in the embroidery industry.

The SAN®1 GEBEDUR®, with its special design and a titanium nitride coating, offers highest stabillity and maximum resistance against wear.

The blade design of the "KK" version corresponds to the standard DB x K5 needle. However, due to its shorter shank, bending resistance is lower.


POINT STYLES OF THE DB X K5

Standard point rg and point variations

In various application tests the RG-point proved to be the most suitable point across a variety of materials. Therefore the RG-point is the standard point style for Groz-Beckert embroidery needles.

 

For other applications the following point styles are available:

FG / SUK

FFG / SES

R

The needle stability

The other needle systems here were not specifically designed and produced for embroidery. Their application related features are designed for the use in single needle lockstitch machines. Nevertheless, many embroidery factories still use these needles today.

 

Their stability, defined as resistance against bending, is show in the diagram above and can be compared with the DB x K5 variations.

 


KNOWN APPLICATION PROBLEMS AND POSSIBLE SOLUTIONS

On knitwear

To avoid material damage when embroidering knitted fabrics, it is recommended in most cases to use needles with a ballpoint. On fine knitwear the standard point RG (also FFG) and on coarse knitwear the FG-point.

 

In addition, needle size has a big influence on material damages. It goes without saying; tests with the requested needle size should be done before starting production.

On woven fabric

Whether on fine or heavy woven fabrics, if the ballpoint is too big or the used needle too thin, problems will occur during the embroidery operation. Irregular appearance of the embroidery design, thread breaks and also needle breakage can be the result.

 

High stability and at the same time maximum material protection are required! Features which the needle system DB x K5 offers in all sizes.

On leather

Cutting points are not suitable for this application. The changes in the stitching direction will result in previously sewn threads being cut, excessive perforation of the leather and irregular stitch hole openings. On fine and medium hard leather the RG- and R point are proven and on hard leather the R point is recommended.

 

Penetration forces through leather are relatively high, so needles must offer highest stability. The DB x K5 and in paticular the DB x K5 SAN®1 GEBEDUR® meet this requirement.
