Abstract
A device for providing improved measurements of logs. The device includes a feed path of the logs, configured to feed the logs in a direction orthogonal to the axis of the logs; and one or more pick-up members spaced from one another in a direction transverse to the feed path of the logs. The pick-up members are adapted to pick up individual logs from a pick-up position along the feed path; and transfer each log from the measuring position back to the feed path substantially in the position in which it was picked up.
Claims27
A device for measuring parameters of a log of wound web material, comprising:
- a feed path of the logs, configured to feed the logs in a direction orthogonal to the axis of the logs;
- at least one pick-up member adapted to:
- pick up individual logs from a pick-up position along the feed path and move the individual logs to a measuring position;
- and
- transfer each log from the measuring position back to the feed path.
The device of claim1, comprising a log diameter measuring system.
A method for manufacturing logs of web material, comprising the following steps:
- sequentially producing logs of web material;
- feeding the logs of web material in a feed path, in which the logs of web material are fed in a direction orthogonal to the axis of the logs;
- by at least one pick-up member, picking up a log from a pick-up position along the feed path of the logs;
- measuring at least one parameter of the log picked up;
- returning, by said at least one pick-up member, the log to the feed path.
