Karl Mayer has been operating successfully in the Chinese woven glass fabric market with its sizing and warping machines.

Buyers include existing customers, who are expanding or upgrading their capacity, but also companies that are new to the woven glass fabric sector.

Woven glass fabrics are mainly used as the carrier material in the production of copper clad laminates.

Karl Mayer owes its success in 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. The company can supply the right machine technology for every processing stage.

The warp preparation sequence for processing glass can be adapted flexibly to suit the intended end-use, especially in terms of the tension regulation and the arrangement of the drying zone. For example, the number of drying cylinders can be varied as a function of the yarn count.

A machine for processing extremely fine glass yarns was successfully installed in February 2018. Experience with processing these fine yarns was also gained during a project that involved the upgrading and modification of older machines.

Karl Mayer is a warp knitting machinery manufacturer.
