❍ The Logos II Evolution drawing machine

The latest technology . . .

through a sensor arm on each capstan • Easy operation: short holing and single jog (forward and backward) of the blocks at each capstan position • Drawing capstans made of induction heated forged steel yielding hardness up to 62 HrC for increased working life • HMI: easy access to the working parameters through the Operator Control Desk • Safety of the Machine: all the parts of the machine as well as the electrical control system have been designed and built to ensure the highest safety for the operator • Soap Box refilling is possible while the machine is in operation. All of those result in a very innovative drawing machine that, in the version with 900mm diameter capstans, is able to draw high carbon wire rod with a 14mm diameter and perform at a mechanical speed of 18m/s.

• Direct air cooling system: newly designed air ducts allow lower pressure losses which result in higher machine performance and improved wire quality • High-efficiency transmission system: the combination of high-efficiency gear box, belt and pulleys results in very low energy losses and minimum required maintenance • Pre-aligned modular frame facilitates easier installation at customer site • Easy maintenance: the machine has been specifically designed to minimise the maintenance and facilitate better access to the maintenance points in order to reduce the down time • Easy cleaning: the capstan/die box area has been specifically designed to easily eliminate the dust, scale and lubricant coming from the drawing operation, thereby respecting the operator’s health • Compact design: the machine frame has been optimised to reduce the general dimensions of the machine while keeping the ergonomics unchanged • High sensitivity speed control:

COnTInUUS-Properzi has designed the latest state-of-the-art vertical axis high-carbon wire drawing machine. The logos II Evolution drawing machine, with available capstan diameters of 900, 760, 670 and 500mm, is the evolution of the world’s most well-known drawing machine, the logos. For decades, hundreds of logos machines have been sold all over the world, while keeping its main configuration and legendary toughness and reliability. The new machine benefits from the most modern design and construction technologies and has been engineered to maximise overall efficiency and safety while minimising maintenance cost. Here are some of the areas on which the re-design was focused: • High efficiency narrow gap cooling system: the widespread system of narrow gap cooling, which has been one of the key factors of the logos machines, has been further improved to yield even higher efficiency and better reliability
