Apparatus for overturning long-web rolls

An apparatus for overturning a long-web roll, wherein said long web has been wound up and placed on a first resting surface in a first state such that a longitudinal wind-up axis of the long-web roll is substantially parallel to the first resting surface, then is overturned to a second state, in which the longitudinal wind-up axis is substantially perpendicular to the first state, and transferred onto a second resting surface, the apparatus comprising:

• i) a chuck for holding the long-web roll, which is placed on the first resting surface, by nipping an outer circumference of the long-web roll from both sides in a radial direction,
• ii) a support capable of being set at a supporting position that stands facing a front end face of the long-web roll, which is held by said chuck, said front end face being directed towards the side of the second resting surface,
• iii) a rotating transfer unit operable for rotating said support and said chuck together with each other by an angle of approximately 90.degree. and thereby placing the long-web roll, which is held by said chuck, on the second resting surface such that said front end face may rest on the second resting surface, and
• iv) a unit operable for moving said chuck with respect to said support, which is set at said supporting position, in the direction along the wind-up axis of the long-web roll after said rotating transfer unit begins operating, and thereby bringing said front end face of the long-web roll into contact with said support.
