In principle, a differentiation is made between a railway overpass and a strip transfer during the transfer. In material webs with a very high basis weight is usually a strip transfer system with Strip transfer application because the web as a whole would be too heavy to transfer to the next position.
  • a strip about 20 cm wide is cut and guided to the end of this device. Then the strip is driven to full width. In this case, this is usually a arranged in the cross-machine direction at the edge of the web strip, which is also referred to as edge strip.
