A method for sawing a metal tube (3) or a hollow section is disclosed. The method includes using a band-saw machine, which has a stationary lower saw part (1), having a saw table (2) for securing the metal tube (3) or the hollow section to be sawn, and an upper saw part (4), which is movable in relation to the lower saw part (1) and which has a revolving saw band (5). The revolving saw band (5) penetrates the metal tube (3) or the hollow section via a feed motion (13) of the upper saw part (4), which is performed in relation to the lower saw part (1). For performing a saw cut, the revolving saw band (5) is guided through the metal tube (3) or the hollow section. The feed motion is carried out substantially counter to the force of gravity.

A machine for cleaning up fruits, particularly strawberries and radishes is disclosed. The machine includes closed loop conveyor belt (5) for conveying fruits, a vacuum-generating means (8), and first cutting means (11). The closed loop conveyor belt (5) is provided with an upper conveying branch (5a), a lower returning branch (5b) and two front and rear connecting portions (5c, 5d), respectively, a plurality of holes (6) that are formed in the conveyor belt (5), and the conveyor belt (5) is movable by rollers (3, 4) along a predetermined advancing direction (A). The vacuum-generating means (8) includes distributing means (10) arranged under at least a predetermined portion of the upper conveying branch (5a). The first cutting means (11) cutting fruits is arranged in the plurality of holes (6) according to a cutting line substantially perpendicular to the advancing direction (A).

A method and an apparatus for horizontally splitting a mineral wool web includes a conveyor having a first direction of travel adapted for receiving and advancing a cured mineral wool web in said first direction. At least one dividing device is provided for longitudinally dividing the cured mineral wool web into at least two sub-webs as said cured mineral wool web is advanced passed said at least one dividing device. At least one lifting mechanism is provided downstream of the dividing device so that a section of the conveyor is adapted for lifting a sub-web. At least one horizontal cutting device is provided for horizontally cutting the sub-web whilst lifted in said conveyor section.

A bandsaw having a shaped band blade, at least one pair of flywheels (5, 6) arranged to move the shaped band blade; a motor member (7) connected to at least one flywheel of the pair of flywheels; a bench (8) for supporting and feeding at least one object to be cut, wherein the shaped band blade (1) has a band having a variable width between an area (2) of minimum width and an area (3) of maximum width.

A slotted tube shaft carrying a blade head of a blade twister rotates in a slotted, stationary bearing housing for an endless band-shaped cutting or sawing element supported by two axially spaced subassemblies each having C-shaped, axially spaced, and slotted inner and outer bearing washers radially between the slotted stationary bearing housing and the slotted tube shaft. The inner and outer washers are fixed in the stationary bearing housing against rotation relative thereto with slots of the stationary bearing housing and washers radially aligned with one another. Respective sets of at least three roller bearings centered on and angularly distributed about the axis and fixed against angular movement between each of the inner washers and the respective outer washer. Each roller bearing radially outwardly engages the slotted stationary bearing housing and radially inwardly engages the tube shaft.

A machine tool, in particular a sawing machine, with a tool for metal cutting, in particular a saw band or saw blade, a drive device for driving and/or moving the tool, a controller for the drive device in order to control and/or regulate the drive device with a process dataset, as well as a communication device for data exchange between the controller and an external data memory and/or an external computer. The controller includes a detector for identifying the tool. A system for optimized operation of such a machine tool which additionally includes an external data memory and/or external computer is also provided.

The safety attachment provides preferably 4 video cameras mounted around a bandsaw blade and looking parallel to the blade direction. Each camera CCD sensor is partly scanned in mode 1. In mode 1 an axis corner of each scanned area is aligned with the camera axis, produced to the table, defining a corner of a parallel-sided protected volume including the entire exposed blade. The blade is rapidly braked when the attachment detects a glove intrusion. In the alternative fully scanned mode 2 the protected area extends outside the mode 1 area and a warning only is emitted on intrusion.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A box unpacking device includes a robot, and a cutting device. A robot hand is attached to a wrist of the robot. The robot hand has a holding device configured to hold a packed box. The cutting device has a cutting blade of which the point is oriented downward or obliquely downward. The robot can move the box held by the holding device in a vertical plane, and change an angle of the box in the vertical plane.
