Direct-Cabling machine

Why are carpet yarns directly cabled on Volkmann cabling machines ?

  • Cabling is a mechanical yarn upgrading process which precedes carpet production.
  • Cabled yarns are ideal for ensuring the formation of a high-quality pile during the manufacture of rugs and carpets.
  • In the direct cabling process, two yarns are twisted around each other in a single operation without the individual strands themselves being twisted.

In contrast to the Two-for-One twisting process, the yarn balloon contains only one yarn with a correspondingly low level of air resistance. Energy consumption levels are thus also considerably smaller. Because only one yarn is drawn from the pot, double-length feed packages can be processed in one loading. This ensures long operating times and the manufacture of substantial knot-free lengths of cabled yarn.

Spindle 285
Energy-optimised spindle reduces energy consumption. Standard producer packages can be used for up-twisting as well as for cabling. Due to the optimised spindle geometry, the yarn count range meets all mayor counts. Thus, the spindle 285 can be used for all typical applications.

Spindles 260 and 220
The new energy-saving cabling spindle enables high energy savings especially when processing cabled yarns – a quantum leap in terms of efficiency. With a different package handling, further advantages can be gained in the production process. This results in a suitable work flow and optimum package sizes.

Package conveyor belt to rapidly clear away the finished packages

Package conveyor belt

In order to improve the ergonomic efficiency of Volkmann machines, the package belt conveyor has been designed in such a way that packages can be removed sideways at the belt exit point. This enhancement results in a further reduction in operating times and easier operator work loads when handling large volumes of yarn.
The package conveyor belt can also be used as an intermediate storage for the cross-wound packages. A photoelectric barrier at the end of the package belt conveyor permits cycled removal of packages.

Further advantages include:

  • A wider conveyor belt surface, designed for removing all the cross-wound packages from one machine side.
  • A trough-shaped guide plate, preventing packages and tubes from jamming and avoiding the formation of trailing ends.
  • Chutes for continuous removal for fitting at the transport ends are available as an option.

Easy and quick yarn threading due to Volco-/Creeljet-Systems

more +

Volcojet is Volkmann's threading system for Two-for-One spindle

The system is characterised by its simplicity, having only one moving component and being powered by compressed air. The complete system is built into each spindle and is activated into operation by pressure on the spindle brake.
Whilst feeding with one hand the thread into the entry tube, the operator can catch the threaded ends with the other hand above the balloon limiter.

The Volcojet system does not require any working aids.

Further advantages are:

  • Low threading times
  • High production/operator/spindle
  • Low operation cost
  • Low maintenance cost
  • No manual threading required


Computer-controlled electro-mechanical gearbox

This computer-controlled drive system is the perfect solution to the market's requirement for fast, effective adjustment to a new yarn batch, accompanied by increased machine availability.


  • Quick, easy and saved settings
  • Less labour efforts
  • Higher machine availability
  • Higher production and reliability
  • Emergency stop function

The access and the adjustment of the production parameters like twist, spindle revolutions and twist direction, as well as the running time, can be done by authorized personal on a touch screen at the main computer.

The production parameters entered can be stored in an article library and called up whenever required.
Delivery speed and operating hours, as well as manually entered adjustment values can also be called up.
The computer is equipped with a USB connection.

This computerized drive system will ensure a synchronized start and stop sequence, as well as an electronically controlled twist level during production.
Furthermore the electronic drive includes an immediate disengagement of the take-up drive, in case of an emergency stop.

Yarn path with direct-cabling

more +

In a direct-cabling machine, one feed-package is loaded into the protection pot.

The yarn end is unwound and tensioned by a yarn-brake located above the package in the pot.
The second feed-package is loaded into a creel, unwound, and tensioned slightly before it enters the lower hollow shaft of the spindle.
This yarn end wraps around the storage disc and forms a balloon around the pot package.
At the balloon apex, both yarns meet and wrap around each other, which thus dissolves the false twist in the balloon yarn.
At the meeting point, both yarns must have the same tension in order to form a balanced composite yarn with no residual torque and equal lengths of component yarns.

In practice, the precise setting of the tension is determined by experiment.
Whenever the spindle speed is altered, the pot-yarn tension must be adjusted to compensate for a consequent increase or decrease in balloon tension.
The most accurate test for balanced conditions is to measure the lengths of both ends after unplying and detwisting.

Creel yarn brakes for the carpet yarn manufacture

more +

The various creel yarn brakes provide for our customers optimal unwinding properties for their individual yarn materials.

Crocodile brake

The crocodile brake ensures constant yarn take-up with reproducibly adjustable take-up forces.
Tension fluctuations in the yarn, such as may be caused by an inferior unwinding property of the supply package, are compensated.

Hysteresis brake

In addition to the proven solution for the feed pot package, the Volkmann Product Line has now also developed a special hysteresis brake adapted to the requirements of the creel.
The advantages of these brakes are as follows:

  • High precision
  • Simple and fast adjustment
  • Wear-resistant and robust yarn guiding elements
  • Absolute reproducibility from brake to brake

Roller yarn brake

The central adjustment are located per machine side at the headstock.
The main yarn guide roller is actuated by compressed air. Its extended axel carries a pair of wear-resistant friction discs similar in design to the well-known hysteresis dome tensioner, ensuring perfect yarn guidance.
This new roller tensioner offers the following advantages:

  • Pneumatically controlled, centrally adjustable per machine side
  • Significant reduction of setup time
  • Wear-resistant and robust yarn guiding elements
  • Extremely uniform unwinding of yarn in the range of 20-200 cN
  • Knots and splices pass easily
  • Tender treatment of yarn
  • Adjustment errors minimized / avoided
  • Easy processing of specialty yarns
  • Simple yarn thread up
  • Separation of mechanical and textile components
