Method and apparatus for replacing a roll of polystyrene foam sheet with empty core roll

摘要

A surface winder for forming mill rolls of sheet material such as polystyrene foam sheet features a surface winder with an automatic web or sheet material transfer arrangement whereby a full mill roll is displaced and replaced by an empty core. The empty core automatically receives the severed end of the web and the winding operation continues on the empty core in an uninterrupted fashion.
