Frequently Asked Questions
How do I choose the right ring finish based on traveler speed?
The ideal ring finish depends on traveler speed and yarn count.
Download our Ring Selection Guide to quickly identify the best finish for your spinning application.
Do I need a specific traveler brand?
No special brand is required for RZD Protected rings, but best results are achieved with reputable brands like Bräcker.
Is there a price difference between flange 1 and flange 2?
No, both flanges cost the same. The choice depends on practical experience: flange 2 is typically used for coarser yarn counts (NE 20 and coarser) and is recommended for core-spun yarns.
What is the smallest ring diameter you can produce?
We manufacture rings down to a 32 mm internal diameter for super-fine counts. For inner diameters under 36 mm, flange 1 or 2 is suggested.
Which flange types are available?
We produce all custom flanges based on customer requirements. Common types include:
- Normal flange
- Asymmetrical “Anti-Wedge” flange
- Flanges 1 and 2 for fine and super-fine counts
What should I do when installing RZD protected rings for the first time?
Follow our recommended start-up program for optimal performance.
How can I reduce yarn and cops hairiness?
Follow our specific recommendations to minimize hairiness.
Do you supply rings mounted on aluminum bases?
Yes. Our brochure lists all SRAB (Spinning Ring on Aluminum Base) options for different frame types.
How do I select the correct tube size for a given inner ring diameter?
Refer to the guidelines for advice on choosing the right tube size based on internal ring diameter.
How can I compare travelers across different brands?
A detailed traveler comparison guide is available in the attached guideline.
