ABSTRACT:
A web winder of a turret winding type is provided with a first spindle secured to a first drive shaft. A second spindle is secured to a second drive shaft. Positions of the first and second drive shafts are changeable in the web winder. A changeover device changes over winding of a web wound about the first spindle to winding about the second spindle. A cutting drum is disposed on a first side with respect to a web path of the web, and has a cutter for cutting the web in a width direction thereof. A receiving drum is disposed on a second side with respect to the web path opposite to the first side. A drum support arm supports the cutting and receiving drums in a rotatable manner and in a manner of contacting drum peripheral surfaces of the cutting and receiving drums on each other.
