For the standard types of textile pins we use electric steel with a maximum purity and a very high percentage of carbon. The wire used as basic material is selected with utmost care and used only if it unconditionally meets our specific requirements: maximum accuracy in diameter, perfect roundness, absence of scores and pores on the surface, and perfect structure given by even distribution of the fine carbide grain as result of careful annealing. For special purposes we also manufacture pins from rust- and acidproof chrome nickel steel alloys, for example V2A, V3M extra and V4A. Another special steel is used for fibrillating pins and perforating pins which enables us to offer them in high wear resistant quality. Further steel qualities can be processed on customer request.

Taper and Cylindrical Length
Sketches 1– 4 show the standard length of the taper and the cylindrical part. These values have been adopted for the four main types of textile pins. Regardless of these standards, however, we can provide any other length and taper as well.
Angle of Taper
The standard angle of the taper of our different types of pins which has proven to be ideal for fibre guidance and longevity is the result of our decades of experience.If desired, we can also supply pins with longer or shorter taper. In addition, thanks to our modern optical and digital measuring equipment and control instruments we are able to produce any pin according to sample and/or drawing with maximum accuracy.

Rounding
Shape
We produce flat pins with head (see sketch 5) and flat pins without head (see sketch 6). The numbering of their width (no. 1) and thickness (no. 2) is similar to the numbering used for round pins.The standard angle of the taper of our different types of pins which has proven to be ideal for fibre guidance and longevity is the result of our decades of experience. If desired, we also supply pins with longer or shorter taper. In addition, thanks to our modern optical and digital measuring equipment and control instruments we are able to produce any pin according to sample and/or drawing with maximum accuracy. For further technical details please refer to DIN ISO 9904.
Hardness
Our various types of flat pins are supplied with hardness degrees adapted to their intended use, with special importance on an even hardness and temper.
