Schlafhorst and Rieter Autoconer machines are covered together on this page because Rieter now owns the Autoconer product line — the Autoconer X6 is a Rieter machine, and Schlafhorst's earlier Autoconer 338, X5, and X6 generations share the same winding-head lineage. If you're searching for either name, this is the right page; a separate Rieter-only guide would just split the same information across two pages.

Identifying the Correct Taper for Your Machine
Both Schlafhorst and Rieter Autoconer machines are built around the same two industry-standard taper angles, but which one your specific heads are configured for depends on the machine generation and how it was set up at installation — it isn't safe to assume from the model name alone. Check the machine's technical documentation under the spindle or cone-holder specification section, or look for a taper marking on the spindle assembly itself.
Schlafhorst generations also differ in notch type between the older Autoconer 338 and the newer X5/X6 range, which is a separate confirmation from taper angle — get both right, since a correct taper on the wrong notch type still causes doffing failures. If you can't confirm either from documentation, a photo of an empty cone holder on the actual machine is the fastest way for us to match the right specification. See our full paper cone specifications page for the complete taper and dimension reference.
Choosing the Right Surface Finish for Your Yarn
Surface finish is the friction interface between the cone and the first few yarn layers wound onto it — get it wrong and the yarn slips before tension builds, regardless of how accurate the taper is.
Smooth finish suits natural-fibre yarns at standard winding speeds, where the yarn's own surface irregularities provide enough grip against the cone. Velvet finish adds controlled texture for synthetic yarns, compact-spun cotton, and any yarn wound at high speed, where a smooth surface alone doesn't generate enough friction to hold the opening layers. Embossed finish is used for high-twist or high-liveness yarns that need a stronger mechanical anchor during early-layer winding to stop the package springing back on itself.
On a high-speed Autoconer line specifically, the right finish affects unwinding behaviour downstream (a cone that grips too little sheds yarn unevenly at the next process), package build (slippage on the first layers throws off the whole package geometry), and handling during transport (a package that's loose at the core is more prone to telescoping in transit). Tell us your yarn type when requesting a quote and we'll confirm the right finish — see our paper cone for spinning mills page for sourcing context.
Confirm Your Spec Before Ordering
We don't guess at fit, and we'd rather you didn't either. Before placing a sample order, send us one of the following on WhatsApp: the dimensions of the cone you're currently running, if you have them, or a photo of an empty cone holder on your Schlafhorst or Rieter machine. Either one is usually enough for us to confirm the correct specification and quote against it, without needing a spec sheet from the machine manufacturer first.
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 sample batch is the fastest way to do that. For everything else this page doesn't cover, see the full machine compatibility hub.
