Your partner for a perfect splice

Künneth & Knöchel KG is a manufacturer of vulcanizing units for rubber conveyor belts and have been manufacturing vulcanizing units for worldwide use since 1930.

Each vulcanizing unit is manufactured specifically for its purpose. We build vulcanizing units for fabric and steelcord conveyor belts up to a belt width of 3,200 mm. The heating plates and pressure beams we use are always made of high-quality aluminium. As a result, our vulcanizing units achieve a very long service life with high tensile and bending strength. They are available in rectangular or rhombus-shaped 16,7°, 22° or 30° shapes.

The heating plates are electrically heated by flat tube heating elements or silicone heating foils. These flat tube heating elements are embedded in a stainless steel tube casing and thus protected against rust and water penetration. Due to the direct contact of the tubes to the heating plate body, a very fast heating time is achieved. The heating foils are made of silicone and are temperature resistant up to 220 °C. The heat flow is uniform everywhere as the heating foil covers the entire surface.

For accelerated cooling, we offer our vulcanizing heating plates with optional compressed air / water cooling ducts. The heating plates can be cooled down with the water cooling system within 10-15 minutes to 80 °C. The electrical control of our vulcanizing presses can be either manual or fully automatic.

We always store a very large range of spare parts, so that a 24-hour service is usually guaranteed within Germany. All vulcanizing units are extensively tested by our qualified specialists before delivery, such as the safety and functional tests according to actual machine directive, in order to deliver optimum and safety quality. Furthermore we are certified according to DIN EN ISO 9001:2015. Because only a perfectly functioning vulcanising unit guarantees an optimal splicing of the conveyor belt.
