Traversing Mandrel Production Lines
Continuous hose production on traversing mandrel lines gives the highest output and efficiency. RKN engineers and supplies complete plants with a custom layout. A line includes several in-line rotating heads for rubber and fabric wrapping, helix wire reinforcement, cover layer and nylon tape, plus automated infeed and outfeed. Dedicated unwrapping and mandrel extraction lines can complete the cycle.
Technical Features
Rotating Mandrel Lathes
Producing hoses on lathes gives maximum flexibility, because the machine adapts quickly to different sizes and recipes. RKN lathes have semi- or fully automated carts and cover a wide range of hose IDs and lengths. A synchronised drive between mandrel rotation and cart motion ensures precise application of rubber and fabric reinforcement.
Technical Features
Rigid Mandrel Extraction Lines
RKN engineers and supplies automated machines for extracting rigid mandrels. Depending on the customer's process, the machine either pulls the mandrel out of the firmly held hose or pulls the hose off the mandrel. Both solutions give safe, smooth extraction through a PLC-controlled process with high consistency and repeatability, which improves hose quality. The lines can be fitted with a sequence feeder and an outfeed rack.

Frequently Asked Questions
What hose sizes can an RKN traversing mandrel line produce?
RKN builds complete traversing mandrel plants for hose ID 1/2" to 10", with a custom layout, mandrel length matched to the plant, and automated infeed and outfeed.
Traversing mandrel line or rotating mandrel lathe: which one do I need?
A traversing mandrel line produces hose continuously and gives the highest output and efficiency. A rotating mandrel lathe gives maximum flexibility, adapting quickly to different sizes and recipes. RKN builds both and can advise on the best fit for your production.
Can RKN also supply mandrel extraction?
Yes. RKN builds automated rigid mandrel extraction lines that either pull the mandrel out of the held hose or pull the hose off the mandrel, under PLC control, with an optional sequence feeder and outfeed rack. Dedicated unwrapping and extraction lines can complete a traversing line.
