Identifying the Correct Taper for Your Savio Machine
Savio's Orion, Polar, and Espero autoconers span more than one generation of winding-head design, so the taper your machine takes isn't something you can safely assume from the model name alone — it depends on how the specific heads on your line were configured. Check the machine's technical manual under the cone-holder or spindle specification, or look for a taper marking stamped on the spindle assembly itself.
Send the current cone dimensions, exact machine model and approved drawing or physical sample. A holder photograph helps explain the setup but cannot establish dimensional fit. Confirm the proposed cone through a trial on your own machine before accepting a bulk order.
Choosing the Right Surface Finish for Your Yarn
Surface finish is what grips the first few wraps of yarn as the package starts building — it matters as much as taper accuracy, because even a correctly seated cone will let yarn slip if the surface can't hold it.
Discuss smooth, velvet or embossed finish using your actual yarn, count, winding settings and downstream process. Compare starting grip, package build and unwinding against the approved reference. A fibre type or machine brand alone does not establish the right finish.
On a Savio autoconer specifically, getting the finish right affects unwinding behaviour at the next process (a cone that grips too little sheds yarn unevenly), package build quality (slippage on the first layers distorts the whole package geometry), and handling in transit (a loose core is more prone to telescoping). Tell us your yarn type when you request a quote and we'll confirm the right finish — see our paper cone for yarn winding page for more on how finish interacts with winding performance.
Confirm Your Spec Before Ordering
Send the current cone dimensions, exact machine model and approved drawing or physical sample. A holder photograph helps explain the setup but cannot establish dimensional fit. Confirm the proposed cone through a trial on your own machine before accepting a bulk order.
Cones are supplied in the taper angles and finishes listed above; you confirm fit against your machine's own cone holder before committing to a bulk order — a small sample batch is the fastest way to do that. For everything else this page doesn't cover, see the full machine compatibility hub.

With a package taper range of 0° to 5°57′, the Polar Evolution covers both our 4°20′ and 5°57′ taper families as well as cylindrical packages. The taper a given line uses depends on its drum and head setup, so confirm it from your current cone or the machine documentation before ordering.
