For special quality requirements of worsted yarn spinning

For specialists in the field of spinning and twisting:

Used for very sensitive yarns, for the highest quality demands with respect to uniformity and cleanliness, J and HZ rings made of sintered steel from R+F can’t be beat.

Sintered rings facilitate maximum speeds with simultaneously lowest head contamination. They develop their advantages in particular with draw twisting with hard chrome steel travellers at highest take-up speeds. Another application area is the twisting of special yarns with nylon travellers on large ring diameters.

J / HZ rings made of sintered steel are characterised by

Very high manufacturing accuracy
The highest demands on cleanliness
High wear resistance
Uniform thread pulling forces and low yarn breakage values due to the secure lubricant feed

Additionally, HZ rings are characterised by

High quality standards on the uniformity and cleanliness of the yarn (bright, soiling-sensitive yarns)
Processing of synthetic continuous filaments, tyre cord twine, glass yarn, and sewing threads
