Abstract
A system and method for controlling the tension of an internal diameter saw blade by controlling the temperature of the blade while it is still rotating. The blade temperature is controlled by regulating the temperature of the wash water flow associated therewith. In one embodiment blade tension is periodically measured and, when the tension falls below a predetermined limit, the temperature of the wash water stream is decreased for a period of time until the tension increases to a preselected value.
Claims6
A method for controlling the tension of an internal diameter saw blade while sawing an object;
- comprising the steps of:
- directing a stream of fluid onto the cutting edge of said saw blade after said blade passes through the object being sawed;
- regulating the temperature of said fluid to control blade tension;
- and
- measuring the tension of said saw blade and regulating said fluid temperature responsive thereto.
A method for controlling the tension of an internal diameter saw blade while sawing an object;
- comprising the steps of:
- directing a stream of fluid onto the cutting edge of said saw blade after said blade passes through the object being sawed;
- regulating the temperature of said fluid to control blade tension;
- monitoring the tension of said sawblade;
- and
- decreasing the temperature of said fluid when said tension falls below a predetermined value.
A system for controlling the tension of an internal diameter saw blade comprising:
- means for directing a stream of fluid onto the cutting edge of said saw blade;
- means for regulating the temperature of said fluid to control blade tension;
- and
- means for measuring the tension of said sawblade coupled to said regulating means, wherein said regulating means is responsive to said measuring means.
