1. A clamping device for clamping a log, the clamping device comprising:
- a frame;
a supporting arm fixed on the frame for supporting the log;
a pair of clamps for clamping the log;
at least one post;
a base plate for carrying the pair of clamps, the pair of clamps moveably disposed on the base plate for changing a distance between the clamps and the pair of clamps moveably disposed on the base plate to adjust a horizontal position thereof, and the base plate moveably disposed on the frame for changing a distance between the clamps and the supporting arm, wherein the at least one post is a screw and the base plate is moveably connected to the at least one post, being threadedly engaged therewith, and wherein the base plate moves relative to the frame via rotation of the at least one post.

Abstract
A clamping device is described for clamping a log such as a log of wound material. The inventive clamping device addresses the need for more efficient or flexible clamping systems for logs of wound material that may vary in their diameter, wherein the clamping allows the logs to be cut by a cutting machine to sections of desired length.
