A cutting machine having a first wheel pair and an opposite second wheel pair, an first vertical wheel, an opposite second vertical wheel, a first drive wheel, a second opposite drive wheel, and a single cutting blade, the first vertical and the second vertical wheels being configured to travel simultaneously and in a same horizontal direction, the first and the second wheel pairs being configured to travel simultaneously and in a same vertical direction, the first wheel pair having a first slanted wheel and the second wheel pair having a second slanted wheel, the single cutting blade being routed over all wheels such that at any moment during a travel of the single cutting blade while driven by the first and second drive wheels, a vertical blade portion extends between and can travel horizontally with the first vertical wheel and the second vertical wheel during vertical cutting and a horizontal blade portion extends between and can travel vertically with the first and second wheel pairs during horizontal cutting, wherein the slant of the first slanted wheel and the slant of the second slanted wheel prevents intersection of the horizontal blade portion and the vertical blade portion.

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 sample cutting assembly includes a blade, a base block, an external blade guide, and an internal blade guide. The cutter can be used to conveniently remove samples for material testing to determine serviceability or material condition. Apparatuses and techniques for using the sample cutting assembly are also disclosed.

The present invention relates to a method for cutting rigid foams, especially slabstock P(M)I foams. A method is provided here, by means of which it is possible to cut these rigid foams even in relatively high layer thicknesses of, for example, more than 3 mm, without material loss, which is produced in relevant amounts, for example, in the course of sawing as a result of the sawdust formed.

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.
