Needle manufacturer Schmetz has extended its range in the field of embroidery. It has developed new geometries for the needle system DBxK5 for those applications in multi-head embroidery. Schmetz is exhibiting at Texprocess 2013 in Frankfurt.

High quality embroidery processes require the use of special needle geometries. Conventional needle geometries often do not correspond to the requirements, for instance in the processing of sequins, with frequent needle size change or when heavy embroidery threads are used. According to industry-specific requirements, Schmetz has developed new geometries for the needle system DBxK5 for those applications in multi-head embroidery.

Focussing on user problems

Bursting of sequins by penetration of the needle is one of the problems in the embroidery industry. Additionally, the needle might clash with the sequin chain cutter, especially in the embroidery of very small sequins. The Ferd. Schmetz GmbH from Herzogenrath (Germany), manufacturer of sewing machine needles, has developed the DBxK5 KK SERV 2 for the embroidery of very small sequins with a diameter down to 3 mm. These needles have a short shank combined with a shank flattening in the shoulder and lower shank area. As a result of the shank flattening, the sequin chain cutter can be set very close to the needle without collision of knife and needle avoiding wear and harm to any of the involved parts. Due to the round cross-section above of the upper shank area the needle can be used in multi-head embroidery machines with needle set screw positioned left-hand or right-hand.

Fixed Hook Setting

Up to now, it was impossible to use very fine and very heavy embroidery thread at the same time in one embroidery head. The Schmetz DBxK5 FHS (FHS = Fixed Hook Setting) now permits such innovative embroidery techniques with extremely different yarn count and consequential use of different needle sizes within one embroidery head.

The characteristic of the Schmetz DBxK5 FHS is that the distance from hook point to scarf and from needle guard to eye/point area remains the same for all needle sizes from NM 65/9 to NM 110/18. Therefore, no hook re-adjustment is necessary when changing the needle size within this range; one sole hook setting fits all needle sizes. Without any problems, each needle bar within one head can be equipped with another needle size which allows the use of significantly different yarn counts within one embroidery head.

Schmetz also offers the needle system 134 FHS with the same properties for Fortron embroidery machines, but in the size range from NM 70/10 to NM 120/19.
