Troester launches next generation skiver

According to Troester GmbH & Co. KG, the continuous innovations in the tyre industry subsequently require latest technology in every single step of the manufacturing process. Facing this demand, the Hanover-based provider for tailor made extrusion equipment has developed a new generation tread cutter, often also known as skiver.

The proven design of both models, the TC600 for passenger car (PCR) treads and the TC1000 for truck/bus (TBR) treads, has been undergoing a thorough re-engineering process based on numerous years of experience in everyday production conditions.

Troester says its tread cutting machines are used wherever efficient tyre manufacturing is a prime consideration. Apart from being integrated in Troester extrusion lines, they may also be installed into any existing lines at customer’s plants.

Designed as a stand-alone unit with an independent programmable logic control (PLC) system these cutters fit-in wherever precise cut-to-length treads are demanded. Communication with any given supervisory and control system is seamlessly provided, says the company.

The stop-and-go working principle stands for high accuracy yet avoiding any unwanted stress on the profile during handling and cutting. For further improvement, an optionally available compensation loop supporting is available. Tread in-feed is performed via high-dynamic drive, specially designed for this operation. The onward sliproll drive, mechanically adjustable to the tread weight, allows optimum transport to the follow-up stations.

Pneumatically operated clamps hold the tread during cutting, which is carried out by a circular knife rotating at speeds of 3,000 min^-1 by direct-drive. Lubricated by a water mist or steam the high rotation speed stands for an improved cutting-quality, says Troester. The servo-driven speed of the knife carriage pre- and return stroke is adjustable for each movement.

One of the major benefits realised is an improved service- and maintenance-friendly design. Features typically known from high precision machine tools have been adopted for the new Troester tread cutters. Capable for handling length up to 2,800 mm for PCR and up to 4,000 mm the TC 600/1000 is prepared for the industry’s demands today and tomorrow, says the company.
