Abstract
The device includes at least a first gripping member and a second gripping member, arranged and controlled so that they extract two winding spindle portions from opposite ends of a log in a longitudinal extraction direction parallel to the axis of the log. The first gripping member and a second gripping member are movable along a log advancing path and extract the two winding spindle portions as they advance along the log advancing path together with the log and the two winding spindle portions.

A device for extracting a winding spindle from a log of web material wound around said winding spindle, said winding spindle being in two portions, comprising at least a first gripping member and a second gripping member constructed and arranged to extract said two winding spindle portions, which together as said winding spindle extend lengthwise through the log of web material, from opposite ends of a log, moving in a longitudinal extraction direction parallel to an axis of the log, wherein said first gripping member and said second gripping member are movable along a log advancing path and extract said two winding spindle portions as said two winding spindle portions advance together with the log along said log advancing path.
A device for extracting a winding spindle from a loci of web material wound around said winding spindle, comprising at least a first gripping member and a second gripping member constructed and arranged to extract two winding spindle portions from opposite ends of a log, moving in a longitudinal extraction direction parallel to an axis of the log, wherein said first gripping member and said second gripping member are movable along a log advancing path and extract said two winding spindle portions as said two winding spindle portions advance together with the log along said log advancing path;
- a conveyor for conveying the two winding spindle portions extracted from the logs;
- and a transfer device for transferring the two winding spindle portions from the gripping members to said conveyor.
A method for extracting a winding spindle from a log of web material wound around the winding spindle, said winding spindle being made in two portions, which together as the winding spindle extend lengthwise through the log of web material, extractable from opposite ends of the log by a first gripping member and a second gripping member, comprising advancing said log along an advancing path while said two portions of the winding spindle are gradually extracted from the log by said first gripping member and said second gripping member, wherein said first gripping member and said second gripping member advance together with the log along the advancing path.
