Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a cutting blade of a cutting machine for a log of woven cloth materials, capable of being manufactured with high reliability and practicality and at low cost, and provide a method for controlling the cutting blade of the cutting machine for the log of the woven materials capable of continuously detecting the state of the cutting blade so as to stop the machine if the state of the cutting blade cannot be operated. SOLUTION: The control device of the cutting blade of the cutting machine for the leg of the woven cloth materials, if the deformed amount of the cutting blade reach to predetermined deformed amounts, stops the operation of the cutting blade. When the deformed amount of the cutting blade are less than other predetermined deformed amount, the control device restarts the operation of the cutting blade. The control device includes a measuring apparatus for measuring at least part of the deformed amounts of the cutting blade; at least one of comparator for comparing the measured deformed amount with at least one of the predetermined deformed amount set by an operator; and an actuator for sending a control signal for controlling start and/or stop of a motor of the machine to the motor according to the signal received from the comparator.

Abstract:
A flexible mandrel is provided for holding cores or core segments so that a roll of sheet material can be wound on the core segments in a winding machine. The mandrel and core segments are coupled through elastic interference between the mandrel and the core segments so that the core segments are arranged either adjacent to each other or spaced apart. A method for producing rolls of sheet material on the novel combination of mandrel and core segments feeds cores in an apparatus, transversely cuts the cores to form portions of core or core segments, feeds a flexible mandrel into the core segments for supporting and maintaining the axial position of the core segments. Coupling is by elastic interference between the flexible mandrel and the core segments to form an assembly in which the core segments are arranged on the mandrel spaced apart or adjacent one to the other.
