The invention is directed to a machine tool for edge machining a workpiece. The machine tool includes a drive unit for a rotary tool, a guide device for guiding the workpiece in a horizontal infeed direction and a chip collecting hood. The guide device includes an upper pressure element and a lower pressure element and one of the pressure elements is settable in the vertical direction relative to the other pressure element and also the drive unit. The chip collecting hood includes a side wall having a cutout for receiving an edge region to be machined of the workpiece. The side wall includes a base wall part and a closure wall part. The base wall part is positioned fixedly relative to the drive unit and the closure wall part is positioned fixedly relative to the pressure element to be settable in the vertical direction. The closure wall part delimits the cutout in the vertical direction.

A cutting assembly for use with a stump cutting apparatus. Cutting assembly including a plurality of tool holders and cutting tools supported in said tool holders. The tool holders placed in a side-by-side relationship on at least one side of the cutting wheel. Further, in an alternative example a single tool holder supports multiple cutting tools.

A method and device for inserting a tongue in an insertion groove in a panel. The method includes displacing a first tongue to an end position of a tongue queue, which comprises tongues under compression, in a tongue queue device, compressing the first tongue, displacing the tongues in the tongue queue by compression forces from the tongues under compression, displacing a second tongue, which is at a front position of the tongue queue, to an inserting device, displacing the second tongue into an insertion groove in a panel by said inserting device.

A method and device for managing and separating a tongue from a tongue blank, including cutting a first edge of a tongue from the tongue blank by rotating a tool which includes a protruding part, and displacing the tongue by the protruding part to a tongue queue. The method and device may include a second tool for cutting a second edge of the tongue from the tongue blank.

A stump grinding wheel assembly having a disk-like wheel body. A plurality of bilateral mounting stations integral with the wheel body and arranged into spiral cluster groups. Each spiral cluster having an inner mounting station and at least one middle mounting station and an outer mounting station. The inner mounting stations are thicker than the middle mounting stations, which are thicker than the outer mounting stations. A pair of opposing side-cutters are disposed on each left and right side of the mounting stations. A separate plunge-cutter may be included with each spiral cluster. The bilateral mounting stations produce conically-helical cutting paths using identical side-cutters. The unequal width of the inner and middle and outer mounting stations enables better management of cutting forces in side cutting mode, which produces smoother operation.
