Tetaş and Tajima Bring Innovations for Embroidery Industry

The standard embroidery presentation of upper and lower threads is no longer sufficient. For this reason, the combination of different materials with the standard embroidery (flakes, beads, cords, lacef etc.), its consideration alongside embroidery in the past years, and the efforts to adapt impossible threads (for example, untwisted yarns with 600 denier and above) to the embroidery come to the fore.

On the other hand, the lower unit prices for embroidery to increase researches to prevent downtime during the use of machines and to reduce thread breakages.

Thanks TFGN2, which was launched in 2014, developments were achieved in five areas.

• The tension spring system on TFGN series was completely renewed on the TFGN2 series in order to shorten the upper thread replacement time and change the tension springs easily when necessary. The time required to replace the upper thread has been reduced to an incredibly 60-70 %, making it a revolutionary breakthrough. In this new tension system, instead of 0.4 mm tension springs, the standard 0.5 mm are used, which are suitable for thick and untwisted threads.

• The process to develop a rotary hook for 600 or higher denier yarns The first generation newly developed rotary hooks on the TFGN2 machines produced in 2014 was later replaced by third generation hooks in 2018.
• The Fine Stitch feature, which offers the ability to change the embroidery frame speed and the rotation automatically according to the pattern structure, is added to the machine’s parameter system in order to prevent the tiresome thread breakages and the effect disturbances on the sharp yarns in the
• Replacing the bobbin in place of the finished one is something every embroidery worker has to do but at the same time expect a solution for. The bobbin replacement on a head takes around between 10-20 seconds depending on the operator’s manual dexterity. Tajima reduced this duration to as short as 8 seconds with the SBC bobbin replacement apparatus system (SBC Bobbin Changer) regardless of the number of heads for to all kinds of machines. In addition, it was made possible with the UBC2 bobbin replacement system to replace the bobbins in individual heads by eliminating the need to change the bobbins at the same time.

• The stamp system, the stamp knives and the central adjustment system of the SQ3 model stamp apparatus were developed between 2013-2017 to meet the market needs.

In the TMCR, TMBR and TMAR model machines launched in 2017, it was ensured that the presser pedal operation stroke and the dead points for the stroke to be lowered could be automatically adjusted through the panel. This way, the need for mechanical intervention to prevent too much pressure on the presser pedal while embroidering on very thick material was eliminated. In addition, development for a multi-cord device on this model machine (Multi Cording Device) continues. Currently, developments to allow this system, which can be operated with single head and up to 4 heads, to operate on machines with 18 heads and more.

The TMCR and TMCP electronic systems are the first models designed by Tajima alone without any support from another company. In addition to these machines, the socalled ESQ-C (Sequin device) and bead apparatus (Bead device) were introduced instead of the SQ3 model stamp apparatuses. It is noteworthy that replacing the flume channel on ESQ-C is possible without having to screw in or out, making the flake center even easier for the operator. The performance achieved with bead apparatus is significant considering the expectation for an innovative automatic bead embroidering in the embroidery industry.
