    Harburg-Freudenberger

    With the manufacture and sale of kneading machines, Hermann Werner and Paul Pfleiderer laid the foundation for a new era in rubber processing. The "MASTICATOR" kneading machine developed in 1900 quickly became a global standard. Independent sales agencies were set up in England, Austria and the United States along with branches in London, Paris, Moscow, Saginaw and Berlin. Werner & Pfleiderer’s further research and development quickly enhanced the growing reputation for technical excellence and high efficiency.

    In Freudenberg 1986, "Krupp Elastomertechnik" was formed after Krupp took over "Werner & Pfleiderer Gummitechnik" and merged with the rubber and extrusion technology located in Harburg.

    In spring 2005, L. Possehl & Co. mbH acquired the entire company from ThyssenKrupp Technologies. Under the new name, "Harburg-Freudenberger Maschinenbau GmbH", the company continued to be successfully and maintained its full product range.

    Farrel

    The long and rich history dates back to 1840 and epitomizes the Industrial Revolution in the United States. In the 1850’s, the Farrel Foundry began production of chilled iron rolls, a crucial component in rubber processing. A rubber calendar order from Henry B. Goodyear provided Farrel with valuable experience and opportunity. Through the merger of Birmingham Foundry and Farrel Foundry emerged the Farrel Corporation. In 1916, the revolutionary Banbury® Mixer was invented by Fernley H. Banbury, which is still today considered a standard in the tire industry.

    As the industry grew, Farrel was at the forefront of developments and innovations for the world’s most demanding tire and rubber companies. In 1963, the continuous mixer (FCM™) was developed and introduced to the thermoplastic processing industry. Another milestone was the acquisition of Francis Shaw of England, expanding the range of products by offering the Intermix®, a series of intermeshing technology mixers invented in 1934 by Rupert Cooke of Francis Shaw.

    Pomini

    The company was founded by Luigi Pomini in Castellanza/ Italy in 1886 and began by reconditioning knitters and machines used in cotton manufacturing. The key factor for Pomini’s growth was the development of the mechanical sector. In 1949, Pomini began manufacturing machines for the rubber and plastic industries.

    In the following years, Pomini’s success grew in Italy and abroad. In 1968, Pomini ventured into the system business by producing and delivering a complete mixing room. In 1984, Pomini acquired Giustina, a manufacturer of roll grinders. In 1988, Pomini was aquired by Techint Compagnia Tecnica Internazionale Spa.

    The company’s main activities were the manufacturing of rolling mills for the steel industry, high precision grinding machines and machines for the rubber and plastic processing industry. In 1987, Pomini released the VIC™ principle – an innovation in intermeshing mixing systems. Pomini introduced the first twin screw dump extruder in 1995 which has become a standard in the tire industry.
