The present invention concerns a device (1) for cutting a plate (70) of a pre-determined thickness, preferably a glass plate. The device foresees: —A frame (10, 31); —A support device (12, 20) for a cutting utensil connected to the frame. In accordance with the invention, the support device (12, 20) is mobile according to an extraction/retraction motion with respect to the frame (10). Further, a hinged lever system (32, 33, 34) is further foreseen, having a feeler element (50), said hinged lever system being kinematically coupable with said support device (12, 20) in such a way as to bind it in a pre-determined initial position with respect to the frame and so that, when said feeler element is pressed against a surface (70), an operation of the hinged lever system is determined which conducts the support device, starting from said initial position, to an extraction motion.

The machine includes a feeding path for the logs to be cut and a cutting head arranged along the feeding path. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes at least a grinding unit, including at least one grinding wheel mounted onto a rotation shaft and co-acting with a side of the disc-shaped cutting blade to grind the cutting edge of the same disc-shaped cutting blade. A controlled approach system is also provided to move the grinding wheel towards the disc-shaped cutting blade.

An intelligent manufacturing system for making cleaning sheet includes a multi-stage drying apparatus and a continuous track with non-stick coating. The drying apparatus has at least two stages and a lifting roller arranged between the two stages of the drying apparatus. The continuous track is at its exterior surface coated with the non-stick coating or covered by a medium having the non-stick coating, so that the manufactured cleaning sheet can have active cleaning ingredients therein protected and be easily removed from the continuous track after being dried. The lifting roller between the two stages of the drying apparatus prevents the adhesion between adjacent layers in the rolled cleaning sheet. The intelligent manufacturing system also has an enzyme-adding apparatus for spraying active enzyme that increases cleaning capacity onto the dried cleaning sheet so as to ensure the enzyme to retain good activity.

A cutting unit includes a spindle housing, a spindle, a mounter fixed to the front end portion of the spindle for supporting a cutting blade, and a fixing flange for fixing the cutting blade to the mounter. The mounter includes a boss portion for axially slidably supporting the fixing flange, the boss portion being fitted to an engaging hole formed in a central portion of the fixing flange, a flange portion projecting radially outward from the outer circumference of the boss portion, the flange portion having a supporting surface for supporting the cutting blade on the front side opposed to the fixing flange, and a cylindrical portion formed on the rear side of the flange portion. The flange portion has a suction hole opening. The cylindrical portion has a communication passage communicating with the suction hole. The communication passage is connected through a rotary joint to a suction unit.

A cutting apparatus for cutting a food object includes at least one cutting blade, an actuator arranged for moving the cutting blade before and during cutting, and an element comprising a receiving section arranged for receiving and abutting the cutting blade, and a supporting section arranged for supporting a food object before and during cutting. During cutting, the supporting section is arranged for being displaced, such as displaced by elastic deformation, by the cutting blade with respect to a position of the supporting section prior to cutting. During moving of the cutting blade, the cutting blade is arranged for displacing the supporting section subsequent to the cutting blade abutting the receiving section. The cutting blade and the element are arranged for being continuously in contact with each other.

A cutting-off machine for the transversal cutting of logs of paper material, including a structure on which the logs to be cut are moved and a cutting unit including a support plate for a blade arranged along a lying plane. The machine includes at least one sharpening unit with two grinding wheels for sharpening the blade on opposite sides of the plane and equipped with an abrasive side and a grinding wheel positioning device with respect to the blade, arranged on each sharpening unit, by which each grinding wheel is placed in a position of contact with the blade in a phase of sharpening the latter starting from a position initial inoperative. The positioning device is equipped with automatic elements for detecting the wear of the abrasive side of the grinding wheels.
