Perfect distribution, short residence time

Our crossheads have compact design and are very easy to handle and quick to assemble.

Description

Our patented Single Valve X-flow System 4/6 is an instant color change system which allows very fast skin or striping color changes.

Substantial raw material cost saving can be achieved with this system through color change scrap reduction. The possible production flexibility and no color change downtime assure high productivity with an X-flow system.

An extrusion group with a single X-flow valve is composed of one main and two auxiliary extruders, an X-flow valve and a triple layer crosshead. The X-flow valve is one of the key components of this color change system. It is located between the auxiliary extruders and the crosshead. The main extruder is used for the uncolored middle layer of the insulation of products without striping. The material flow from this extruder goes directly to the crosshead through a passage in the valve. One of the auxiliary extruders makes a colored outer skin while the other auxiliary extruder supplies its material to the inner layer. Raw material containing the next skin color is fed to the inner layer extruder a certain time before the next color change. This colored inner layer will be not visible since the main insulation and the outer skin hides it.

The function of the X-flow valve is to cross the flow between the two auxiliary extruders. The X-flow valve is activated when the production length of the current color is reached and the inner layer extruder with the next color becomes outer layer extruder. The extruder used previously for the outer layer will now make the hidden inner layer. The skin insulation will start changing color almost instantly and will have the full new color after 5 to 30 seconds depending on the used colors and insulation thickness. Coloring of the inner layer is only needed just before a color change.

The two auxiliary extruders are independent, which means that the thickness of inner and outer layer can be adjusted separately.

Perfect Control of the Cable Position in Your CCV Line

16.9.2026

Over the past 30 years, Maillefer has delivered and started hundreds of catenary continuous vulcanization (CCV) lines globally. We can confirm that successful cable quality needs a perfect interaction between all the various components in a CCV line. To that end, Maillefer and Sikora GmbH, invented a means for securing the cable quality for both past delivered CCV lines and those to be delivered in the future. They named the device Siccon 600.

State of the Art Fiber Feeder

2.9.2026

The productivity of an optical cable manufacturing line can be significantly improved by increasing line speed. The buffering process has introduced entirely new limits for these speeds, making the start-up procedure increasingly important. A rapid ramp-up to production speed may generate substantial scrap before the process stabilizes. Read more
