Abstract: Hole-saws are provided herein, and more specifically to hole-saw assemblies and processes having adjustable platters for multiple simultaneous saw components, optional elimination of a guide drill, and the ability to retrieve cores of a sawed work piece before sawing completely through the workpiece. One hole-saw device, may have a motive force; a base plate rotatable by the motive force; cutters; and locking mechanisms to mount the base plate to the cutters.

Abstract: A stamping die includes a bracket, a resilient member, a floating plate, a connecting member, a supporting plate, and a limiting member. The resilient member is secured to the bracket. The supporting plate is secured to the resilient member. A first end of the connecting member is secured to the floating plate. A second end of the connecting member, opposite to the first end, abuts the supporting plate. The limiting member is secured to the bracket. The connecting member defines a cutout. The limiting member is partially received in the cutout. The supporting plate, the connecting member and the floating plate are slidable together relative to the bracket. The limiting member prevents the connecting member and the floating plate from disengaging from the supporting plate and the bracket when the connecting member and the floating plate are slid relative to the bracket.

Abstract: The invention relates to a marking device for applying acode marking on a piece of wood. The marking device comprises several adjustable marking members, each of which comprising a marking element which is capable of applying a mark on a piece of wood and which is shiftable between different positions or states so as to allow a variation of the code marking to be applied by the marking device. At least one of said marking members (170) comprises a rotatable marking element (171), which is arranged to apply a rotationally unsymmetrical mark on a piece of wood and which is settable in different rotational positions in relation to the marking elements of the other marking members. The invention also relates to a harvesting arrangement for tree harvesting comprising such a marking device.

Abstract: Mold apparatus for molded wood strand three-dimensionally carved articles of manufacture using at least one hole punch comprised of a base and a funnel shaped hole-defining portion having a funnel angle of 20 degrees or greater to vertical for producing molded holes at angles of 20 degrees or greater to vertical, to facilitate insertion of items such as a T nut within the molded hole in an assembly-line like fashion.
