Abstract:
A tread cutting machine, comprising:at least one cutting blade; a blade carriage, said cutting blade being mounted on said blade carriage, said blade carriage being linearly traversable for correspondingly moving said cutting blade in a feed movement; a drive motor outside said blade carriage; and torque-transmission means arranged between said drive motor and said cutting blade for driving a rotation of said cutting blade and selectively moving said cutting blade in the feed movement direction during rotation of said cutting blade such that the feed movement is superposed with the rotation of said cutting blade in said torque-transmission means, at least a part of said torque-transmission means being traversable with said blade carriage, said torque-transmission means part having a lower mass than said drive motor, said motor having one of a closed-loop control device and an open-loop control device for maintaining a rotational speed of said cutting blade substantially constant during cutting blade feed movement.
