711 MA - Mechanical self-expanding chucks with leaves


The Model 711/MA is recommended primarily for unwinding of both steel and cardboard cores.

It is superior for higher weight, speed and grants a perfect core centring. The body of the chuck and the expanders (leaves) are available in steel only. The flange mounting is always custom made and the chuck can be stepped for use with different core sizes. The expanding elements, pin-fitted on a cam, are expanded through the reel rotation combined with the web tension.

Standard sizes available for this Model are listed below.

Features

  • Core diameter: from 70 to 600 mm
  • Chuck length: 170 mm
  • Expansion range: 5 mm on diameter
