Cutting machine for transversal cutting of paper material logs
A cutting machine for transversal cutting of paper material logs has been granted a patent (Publication Number: US11858161B2). The machine comprises a structure where logs are moved for transverse cutting to obtain rolls of shorter length. A cutting unit with a blade controlled by rotary actuators is positioned on the structure. Additionally, at least one sharpening unit with grinding wheels is included to sharpen the blade. The positioning device for the grinding wheels involves primary and secondary carriages that ensure precise contact with the blade during sharpening operations.
The patent claims also detail the inclusion of sensors connected to the primary carriage for detecting the radius of the blade and stopping the carriages at the correct position for sharpening. The primary carriage can consist of two independent units, each with specific functionalities related to the sharpening process. Furthermore, the contact between the grinding wheels and the blade is detected by monitoring the slowing down of the blade, ensuring accurate sharpening. The sensor used in the machine can be an optical, inductive, or ultrasonic sensor, providing flexibility in detection methods for the sharpening process.
