Karl Mayer’s Filsize sizing machine is a hit in China in the production of printed circuit boards. Huge amounts of money are being invested in the electronics sector, especially in China. Most of all the Copper Clad Laminates (CCLs), which are the copper-laminated precursors of printed circuit board production, are supplied by Chinese companies.
Karl Mayer, the well-known textile machinery producer, has been operating successfully on the Chinese woven glass fabric market with its sizing and warping machines. At the end of 2016, the electronics supply industry really started to take off and the first big orders were placed. This was followed by more big orders in the autumn of 2017.Karl Mayer's Filsize sizing machine is a hit in China in the production of printed circuit boards.

The company owes its success on the glass market to its sophisticated warp preparation process. This process uses the principle of single end sizing: the yarns are taken off from bobbins, fed through the sizing bath, dried, and wound onto beams. These are then assembled to produce warp beams for weaving. Karl Mayer can supply the right machine technology for every processing stage. In the initial stage, the glass rovings are gently removed from creels with the aid of the Accutense computer-controlled, hysteresis yarn tensioner and fed to the Filsize sizing machine. This machine for processing filament yarns also focuses on process control without any loss of quality. It processes around 800 yarns – fewer than full warp sizing machines. These do not come into contact during the treatment process, so that they are sized all over. The yarns, which are processed separately, cannot stick together in the drying zone. The separation process, which normally has to be carried out when sizing full warps and which frequently damages the glass fibrils, is now superfluous.
The Filsize also scores points with its accurate yarn tension control during yarn transportation – an important feature, since the non-stretch glass yarn cannot tolerate any fluctuations in tension. If the tension decreases, there is a danger of loose yarns, whereas if it is too high, the yarns can be damaged. To rule this out completely, the yarn tension is monitored and controlled at several places, such as in the size box and at the entry and exit points of the drying stretch.
In addition to meeting the highest quality requirements, the Filesize operates at an exceptionally high level of productivity. This is due to its exceptional operating reliability and unique output. (GK)
