TROESTER Tread Cutting machines are used wherever efficient tire manufacturing is a prime consideration. Apart from their use in complete TROESTER tread lines, they can also be integrated into existing lines as independently functioning units.

After passing through the cooling and drying sections, the profile is cut to the correct length. The cut is carried out during standstill, that means the machine operates in a Start/Stop mode. A programmable logic control system regulates the process and the positioning of the profile according to the pre-selected length. The profile is fed into the machine via a high-dynamic drive, specifically designed for this operation. Pneumatically operated clamps hold the profile during cutting, which is carried out by a rotating circular knife lubricated by a very fine water spray (mist). Subsequent drying of the cut surface is therefore no longer necessary. The cutting and return stroke of the ball-bearing supported knife carriage is by means of an A.C. motor-driven traversing gear box unit.

During cutting, the continuously extruded profile assumes the shape of a sagging loop. The loop size is optically recorded and used for control and regulation purposes, one of which is the calculation of the start speed. After the completed cut, the profile is transported away on a combined belt/roller conveyor. A friction roller conveyor which is either driven by the next transportation unit or equipped with its own drive forms the end of the cutting unit.

• continuous operation;
• no separate drying of the cut surface due to use of minimal water "mist";
• fully integrated unit with programmable controls system which can easily be integrated into existing lines;
• for passenger car (up to 2,300 mm length) and truck treads (up to 4,000 mm length);
• sidewall skiver with angled cut in extrusion direction available as option.
