Abstract: A saw tool, especially a circular saw blade, an endless saw blade, a mill saw blade or the like, with a blade-shaped tool body having detachably connected thereto at least one cutting member with a clamping element between two tensioning surfaces of the tool body. The saw tool is characterized primarily in that for purposes of obtaining the full tensioning and engaging effect of the cutting member and clamping element during a change in position of the clamping and engaging surfaces caused by the clamping deformation, the clamping element includes floating bearing means. The clamping element is an eccentric peripherally having a smaller radius of curvature than corresponding inner surfacing of a recess of an intermediate piece therewith. The intermediate piece for pivotal support at the eccentric is located with play in the recess of the tool body.

Abstract: An edge machining tool in which two substantially identical tool members are mounted on a work spindle with each tool member having peripheral axial portions extending into notches in the other tool member. The aforementioned axial portions are provided with cutting edges and incline downwardly toward the other tool member so that in cross section the tool members define a "V" shape therebetween. At least one threaded adjusting spindle is provided which is held against axial movement on the work spindle and which engages the tool members with threads of respective hand so that by rotation of the adjusting spindle the tool members can be caused to move toward and away from each other on the axis of the work spindle.

Abstract: A method and apparatus for edge machining panels, especially panels having a hard glue layer thereon. Rotary edge cutting tools are presented to the panel edge to be cut. The tools having axially overlapping cutters thereon. There is moving of the tools by equal amounts in opposite directions during rotation of the tools to compensate for wear of the tools caused by the hard glue layer in the panels.
