A slicing machine cuts slices of cutting material. The slicing machine has: a machine housing holding a motor and circular blade driven by the motor; a product feed, which feeds the cutting material to the circular blade; a stop plate; and a slidably arranged carriage, which feeds the cutting material to the blade. The blade is mounted directly on a bearing shaft arranged in the drive motor for the circular blade. The drive motor includes at a stator and rotor, which is detachable from the stator. The stator is in the machine housing. The machine housing has an insertion opening where, in the assembled state, the stator is arranged and through which the rotor is at least partially inserted into the stator. The slicing machine has an attachment device comprising at least one fastener that is configured to fasten the rotor and the stator to the machine housing.

An edge trimming mechanism of an edge banding machine capable of removing scraps includes a cutting device and an air guiding cover. The cutting device includes a motor having a power outputting shaft, and a cutter mounted at an end of the power outputting shaft. The air guiding cover is hollow-shaped, installed outside the motor, and has air inlet and outlet. The power outputting shaft protrudes out of the air inlet and the cutter is at least partially located out of the air inlet. An air exhausting path is defined between the inner wall of the air guiding cover and the outer wall of the motor. Two opposite ends of the air exhausting path communicate with the air inlet and outlet respectively. By the above-described configuration of the edge trimming mechanism, it is effective in removing the scraps produced by the edge banding machine in the edge trimming process.

Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.

Dynamic regulation of contact pressures in a blade sharpening system is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.
