WePack Series

Forming fabrics

For the production of all paper grades and all types of paper, board, and tissue machines.

ANDRITZ Kufferath offers a wide range of forming fabrics for paper, board, and tissue applications. Our product portfolio covers all paper grades and machine types regardless of width, speed, or configuration.

The challenge

Paper mills for packaging papers are confronted with increasing machine speeds, a diversity of machine types, declining furnish quality, increasing demands on paper and board quality, as well as rising energy costs. Our goal is to improve paper strength and printability with simultaneous reduction of basis weight as well as homogenization of the surface topography for better printability.

The solution

Stable fabric design for packaging paper with graphic surface qualities is achieved with a combination of two completely different fabric layers in one functional design. One is oriented to the requirements of graphic paper, the other to the high expectations regarding lifetime in the production of packaging paper. Structure-bound, triple-layer fabrics in warp-bound or weft-bound design results in:

• Forming fabrics with a fine paper side due to a two-shaft design and the use of comparatively thin yarns
• Rugged machine side with noticeably higher yarn diameters, an abrasion-resistant material combination, and longer floating designs

WePack RUN – proven variety

• Forming the basis of the product line

E-Line technology

energy savings of up to 20% at the wet-end of your machine

20% savings

Compared to polyester/polyamide fabrics still predominantly used today, paper produced with E-Line yarns achieves savings of up to 30%. Abrasion-related changes in fabric properties appear substantially later due to less friction between fabric and vacuum-aided dewatering elements. The preconditions for optimum sheet formation similar to that of a new fabric are preserved for longer.
