Abstract
A sawing apparatus is implemented to cut rolls out of an elongated log. An in-feed conveyor pushes the log, and a braking system stops the log at a controlled position. A clamping system then holds the log in place while a saw blade travels to cut a roll out of the log. While the log is being cut, a bending pressure is applied on the log. The roll then is unloaded onto a discharge conveyor.
Claims11
A sawing apparatus for cutting rolls of a web material, comprising:
- an in-feed conveyor for moving an elongated log of a web material along a processing direction;
- a braking system configured to contact with a surface of the log to controllably stop a course of the log;
- a clamping system for holding the log in place;
- and
- a cutting unit including a saw blade movable to cut along a cutting path to cut out a roll from the log;
- wherein the clamping system comprises:
- a first jaw assembly;
- a second jaw assembly spaced apart from the first jaw assembly, the second jaw assembly disposed on an opposite side of the cutting path relative to the first jaw assembly, wherein the second jaw assembly includes a pivotal link operable to cause a rotation movement of a portion of the second jaw assembly for applying a tilting force on a clamped portion of the log;
- and
- a latch operable to selectively block movement of the pivotal link for disabling the rotation movement of the portion of the second jaw assembly.
