Abstract

Abstract A wood-marking tag for wood identification purposes printed with or without markings thereon or punched therein, made of soft material, permitting its cutting without damage to the cutter means. The hardness of the tags is less than that of conventional saws made from steel alloys, to a degree avoiding dulling of the saw and optionally also permitting the punching of markings into said discs by means such as pliers and punchers. The material is preferably a glass-fiber reinforced plastic; preferably suitable for injection-molding. Optimum results are accomplished with plastics selected from the group consisting of 6-polyamide and ABS acylic nitrile-butadien-styrene-copolymers. The tag material in one embodiment is magnetically non-permeable, in another it includes metallic particles to make the tag magnetically permeable. The tag is equipped with projections applying it to the lumber such as for driving it into the lumber and/or for retaining the tag applied to the lumber thereon. In one embodiment, the retaining projections comprise retaining clips, optionally with claws. In various embodiments, the tag is provided with indentations in its outer edge, with apertures near its outer rim, with barbs at its outer edge; with tubular projections at at least one side thereof; optionally with barbs on the tubular projection and/or with corrugated projections, optionally provided with barbs. In other embodiments, the tag is separable into two parts having identical markings, by a weakened line of cohesion, or by a perforated line, optionally asymmetrically with one of the parts having the shape of a segment.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 140 words
A wood-marking tag for permanent attachment to the end face of a log or the like by a magnetized tag-driving device, such as a magnetic tagging hammer and capable of being cut by wood processing machinery without blunting the latter, comprising; a tag body formed of a material which is softer than any ferrous alloy, such as a plastic material; said tag body including a generally flat plate for identifying information; means for permanently anchoring the tag in the log to be marked, the anchoring means being capable of penetrating a distance into the log under the action of said tag-driving device; a tag retaining means on the tag body for releasably retaining the tag on said tag-driving device; said tag retaining means comprising magnetically permeable metallic dust, thereby rendering the tag magnetically attractable by said magnetized tag driving device.
Claim 2
Dependent Claim 140 words
A wood-marking tag for permanent attachment to the end face of a log or the like by a magnetized tag-driving device, such as a magnetic tagging hammer and capable of being cut by wood processing machinery without blunting the latter, comprising; a tag body formed of a material which is softer than any ferrous alloy, such as a plastic material; said tag body including a generally flat plate for identifying information; means for permanently anchoring the tag in the log to be marked, the anchoring means being capable of penetrating a distance into the log under the action of said tag-driving device; a tag retaining means on the tag body for releasably retaining the tag on said tag-driving device; said tag retaining means comprising magnetically permeable metallic dust, thereby rendering the tag magnetically attractable by said magnetized tag driving device.
Claim 3
Dependent Claim 46 words
A wood-marking tag as set forth in claim 1, wherein the tag anchoring means include anchoring protrusions in the form of wall portions depending substantially perpendicularly from the tag plate near the outer rim of the latter, the wall portions including barbs at their outer edges.
Claim 4
Dependent Claim 23 words
A wood-marking tag as set forth in claim 1, wherein the tag anchoring means include tubular projections extending prependicularly from the tag plate.
Claim 5
Dependent Claim 19 words
A wood marking tag as set forth in claim 3, in which the tubular projections are provided with barbs.
Claim 6
Dependent Claim 20 words
A wood-marking tag as set forth in claim 1, wherein the anchoring protrusions are in the form of corrugated projections.
Claim 7
Dependent Claim 63 words
A wood-marking tag as claimed in claim 1, wherein the plate of the tag body comprises two plate portions separated by a substantially straight line of weakening along which one portion can be broken away from the tag body, the identifying information including identical markings on both plate portions, the tag anchoring means including anchoring protrusions on one of the two plate portions.
Claim 8
Dependent Claim 19 words
A wood-marking tag as set forth in claim 6, in which said line of weakness is a perforation line.
Claim 9
Dependent Claim 59 words
A wood-marking tag as set forth in claim 1, wherein at least a portion of the tag plate is thin enough to permit the piercing thereof by punch pliers, so that identifying information can be applied to the tag plate in the form of punch marks which are punched into the tag plate by means of the punch pliers.
Claim 10
Dependent Claim 30 words
A wood-marking tag as claimed in claim 1, said material being reinforced with fibers having a hardness greater than that of said material and less than that of cutting steel.
Claim 11
Dependent Claim 22 words
A wood-marking material as claimed in claim 1, said material comprising materials selected from the group consisting of 6-polyamide and ABS-acylic nitrile-butadien-styrene-copolymers.
