ITMA 2007 September 13-20, 2007 Munich / Germany Hall: A3, Stand: 107/302
Fleissner Machinery for the Man-made Fiber Industry

At ITMA 2007 in Munich, Fleissner will present a range of machines for the man-made fiber industry which are used for the production of standard and special fibers:

The staff at the Fleissner stand will provide additional information on new developments and trends in the man-made fiber market. Visitors can satisfy themselves of the competence and versatility of Fleissner: as a system supplier of production lines and a service provider for research projects. With the extension of its technical center by an extrusion spinning plant end of 2006, Fleissner can now offer its customers optimum conditions for developing the technologies of the future.

Calender
For contact drying and heatsetting of fiber tows and yarns under tension, Fleissner supplies heated cantilever rollers. Depending on the relative fiber forces, the units are provided with a cast central gear housing for 4 or 6 rollers or with individual roller bearings in a steel frame. Godet diameters between 750 and 950 mm and godet lengths up to 2000 mm can achieve tension forces up to 200 kN and speeds up to at least 600 m/min. Energies used are steam, water, thermal oil or electrical power.

Fleissner calenders offer a range of advantages to the operator:

• Long service life, high reliability: The proven and advanced design principle and the elaborate execution ensure smooth operation.
  
  
• Highly uniform process temperatures: All godet types, and especially double-jacket godets and CombiEco godets, ensure highly uniform temperatures over the working width by an optimized flow of heat transfer media and 100% removal of condensate. This results in top product qualities.
  
  
• Increased energy efficiency: The steam cascade system of Fleissner optimizes the energy efficiency of a steam heating system with double-jacket godets. CombiEco godets can be used with conventional steam traps and ensure optimum condensate-free heat transfer with minimum steam consumption and without steam dragging.

Crimper
The efficiency of a fiber line largely depends on the crimper performance. Great store was therefore set by reliability and ease of maintenance for design and construction of the Fleissner crimper. Seven different types covering working widths between 10 and 650 mm can be equipped for numerous special executions. These include steam or finish injection into the stuffer box, nickel-plated or stainless steel design, variable stuffer box heights and replaceable stuffer box tips.

Often imitated but never equaled, the legendary Fleissner quality standard offering highest operational reliability and regular crimp even under adverse production conditions ensures high efficiency of the crimper resulting in an increased return on investment:

• Improved availability: Crimper rollers, bearings and stuffer box can be replaced quickly. The rotating cheek plates on the sides have long service lives with regular wear over the surface. A fast-exchange spare crimper head can be kept available, which reduces to a minimum fiber line downtimes due to maintenance work.
  
  
• Ease of operation: Simple cleaning and adjustment of the crimper reduces downtimes and waiting times.
  
  
• Easy service: The crimper roller surfaces can be reground without having to disassemble the bearings.

Spinning Plants and Fiber Lines
Having obtained the licenses for Lurgi Zimmer spinning technology in 2006 and following the extension of the Fleissner technical center by a single-stage and a two-stage spinning system, thus completing its scope of supply, Fleissner now offers complete systems in the man-made fiber sector for the production of staple fibers from thermoplasts.

Fleissner also supplies installations and components for wet-spinning processes, where spinning solution is pumped through spinnerets into a coagulation bath. Irrespective of the spinning process, Fleissner supplies equipment for fiber processing including can creels, washing machines, finishing units, immersion baths, drawstands, calenders, heatsetters, tow stackers, crimpers and cutting machines.

Special Machinery
Apart from the standard delivery program for spinning plants and fiber lines, Fleissner also develops, designs and supplies special machinery for fiber fabrication. The focus here is on sophisticated and customer-specific solutions using the findings of R&D projects and providing the customer with unique market features and competitive edge.
