The object of the present invention is to provide a winding drum for a sheet-like member which can change reliably the range of air sucking intake holes by a simple structure, and to provide a winding drum which can prevent the generation of an unwanted contact mark on the sheet-like member. This winding drum having a hollow portion which is in communication with the intake holes of the drum body, a changeover member which is releasably attached in the hollow portion and which is formed so as to extend along the inner peripheral surface of the hollow portion, and an air passage (second communicating holes, first communicating hole, and hole) which is provided on the changeover member and which communicates intake holes of a predetermined range in the axial direction of the drum body with the suction device when the changeover member is attached in the hollow portion. So the range of air sucking intake holes is switched by changing the changeover member to another changeover member with another air passage.

Winding drum for sheet-like member

Apparatus for arraying/conveying web-like workpieces such as unvulcanized treads delivered from an extruder. A plurality of forks sequentially lift the workpieces to and from roller conveyors and arrange the workpieces in selected uniform spaced-apart relation on a flat storage area.
