Project Description

Machine Functions

  • The units are configured to customer’s requirements to pay-off pre-made tubular inner cores into the main outer casing extrusion process
  • With high accuracy required, especially with very small diameter lightweight cores, the consistent tension control of the unwinding cores are being fed into the extruder head. This is to ensure that breakages or over stretching is avoided.
  • Each input core is presented on pre-wound flanged drums. These are mounted on cantilevered centre support shafts, which are independently driven by a variable speed electric motor. Each core is fed around its own in-line dancer wheel arrangement, which monitors its tension and provides speed feed-back to allow it to be synchronised to the main line speed.
  • Each station has a compact design with dual unwind shafts mounted in a back to back arrangement minimising floor space used.
  • Drums up to 1200mm outside diameter x 200kg can be accommodated
  • Line speed 100m/minute with start up speed of 5m per minute
  • A bespoke loading trolley can be provided for easy removal and reload of core drums.
