Mesh production

 

World-renowned fine meshes from BOPP are manufactured at our production facility in Wolfhalden, Appenzell, built in 1956 and extended most recently on a significant scale in 2008.
 

Facts

1
  • Over 100 employees, 24 hour operations across two shifts
  • 145 weaving machines
  • 170 tonnes of steel processed every year
  • 24 million kilometres of wire processed every year
  • 450 kilometres of mesh produced every year
  • Fine meshes down to a wire diameter of 0.015mm (15 thousandths of a millimetre)

Warping: winding warp wire in bundles

1
  • Winding the warp wires (longitudinal wire) on the warp beam
  • Warp frame contains over 1000 spools
  • Winding warp wires in bundles

Examples

  • 200 mesh:  8000 wires per metre width
  • 400 mesh: 1600 wires per metre width
  • Average labour input: 33 hours

Feeding: Preparation for weaving

1
  • Winding the warp wires (longitudinal wire) on the warp beam
  • Warp frame contains over 1000 spools
  • Winding warp wires in bundles

Examples

  • 200 mesh, Ø 40 µm, 8000 wires per metre width: feeding time 36 hours
  • 400 mesh, Ø 25 µm, 16000 wires per metre width, feeding time 88 hours

Infrastructure

1

1
  • 145 weaving machines, developed in-house, woven widths up to 2800mm, mostly automated operation with laser control
  • New weaving hall: Special vibration-free floor, fully air conditioned, cleanroom class 10000
  • State of the art, ecologically sound mesh cleaning equipment

Quality control: SD final inspection: Mesh thickness

1
  • Weaving quality: BOPP-Norm (BN), more stringent than ISO Standards, less defects, higher levels of precision
  • Final inspection SD: mesh thickness, SI: mesh count, FI: Optical sight check
  • Traceability: Raw material batch, Machine number, Operator identification, Arbeiter-Identifikation
