Machinery for Hydraulic Hoses

Cutting-edge braiders, spiraling machines and auxiliary equipment for medium, high and extremely high pressure hoses, each built to the customer's specification.

01 — Braiders

Braiding Machines

Cutting-edge braiders with 24 to 64 carriers for medium and high pressure hoses, with steel wire or textile reinforcement. The horngears drive the shuttles, while a dedicated track sensor controls their direction. A PLC-controlled, synchronised servo drive ensures a precise braid, and the haul-off, with automatic opening and closing and clamping force detection, keeps the process smooth.

Technical Features

Configuration with 24 – 36 – 48 – 64 carriers
Horngear speed up to 220 rpm
Tensioning force adjustment up to 140 N
Linear speed up to 5 m/min
PLC controlled synchronized servo drive
Automatic haul-off clamping force detection
02 — Spiraling Machines

Multi-Wire Spiraling Machines

Multi-wire spiraling machines for high and extremely high pressure hoses on flexible or rigid mandrels. The design is based on compact decks with a limited number of carriers, each loaded with several wires. This makes the process very reliable and keeps hose quality stable, even at larger diameters.

A special brake system on each carrier and a synchronous servo drive between the spiraling decks and the traction device lay the wires at constant tension and with high precision. A dedicated wire guide and preformer tooling for each diameter give a consistent curl.

Technical Features

High performance multi-wire spiraling for up to ID 4" hoses
2 – 4 – 6 deck configuration
12 – 40 carriers per deck
Rotation speed up to 120 rpm
Wire preforming with curl formation in diameter and pitch
Electronic drive transmission with PLC controlled motion synchronization
03 — Wrapping Machines

Wrapping & Unwrapping Machines

Wrapping and unwrapping machines that apply and remove the curing tape, in concentric or eccentric design. A synchronous servo drive with automatic pitch control ensures precise wrapping, even at very low tensioning forces.

Technical Features

Concentric or eccentric nylon tape wrapping
Rotation speed up to 800 rpm
Adjustable tensioning force from as low as 5 N
Linear speed up to 60 m/min
Precise unwrapping with position sensor control
Synchronous servo drive with automatic pitch control
04 — Bobbin Winders

Bobbin Winders

RKN bobbin winders spool wire with the precision that high-quality braiding and spiraling require. Constant wire tension keeps the catenary uniform. Machines with electronic brakes have closed-loop load cells on each creel position; mechanical versions use brake cams. A synchronised servo drive with software control keeps spooling precise.

Technical Features

Creel design with up to 18 positions
In-built wire length control by encoder
Dynamic wire tension control 7.5 – 40 N
Spooling speed up to 900 m/min
Wire size range 0.12 – 0.71 mm
Servo drive for constant speed with varying spool diameter
Adjustable brake action during processing
Automatic wire rupture detection
05 — Blow-Out Cells

Mandrel Blow-Out & Proof Test Cells

Complete equipment for blowing out flexible mandrels and proof testing hoses. An expandable coiler eases mandrel detachment, while dedicated clamps hold the hose ends securely. The proof test uses a high-pressure plunger pump unit, combined with an air pump for very high test pressures.

The system delivers fast, reliable mandrel blow-out and a precise multi-phase proof test. Dedicated software controls each phase of the cycle, with recipe management, graphs and an automatic test report. Each cell is designed to the customer's layout.

Technical Features

Automatic mandrel blow-out
Hydraulic and universal clamps for hose end holding
High-pressure pump unit
Pinhole detection during test
HMI with dedicated operator software
Working parameter record for data processing & printing

Frequently Asked Questions

What machines does RKN build for hydraulic hose production?

RKN builds braiders with 24 to 64 carriers, multi-wire spiraling machines with 2, 4 or 6 decks, wrapping and unwrapping machines for curing tape, bobbin winders, and mandrel blow-out and proof test cells. Every machine is built to the customer's specification.

Which hoses can RKN spiraling machines produce?

High and extremely high pressure hoses up to ID 4", on flexible or rigid mandrels. Each deck carries 12 to 40 carriers loaded with several wires each, with rotation speeds up to 120 rpm.

What are the main figures of RKN braiders?

Configurations with 24, 36, 48 or 64 carriers, horngear speed up to 220 rpm, tensioning force adjustable up to 140 N and linear speed up to 5 m/min, with a PLC-controlled synchronised servo drive.

Does RKN supply standard catalogue machines?

No. RKN has no standard catalogue: each machine is engineered around the customer's hose, plant and output. To start, send your hose type, ID range, reinforcement and target output to info@rknhose.com.
