Abstract: A method of manufacturing a chain link (8) of an abrasion cutting chain comprises: providing a metal blank with outer contours of the chain link (8) and rivet holes (14); and providing a ring (15) of a seal material by injection-molding of seal material around at least one rivet hole (14). The method further comprises providing a transfer channel (16) in the metal blank adjacent to at least one of the rivet holes (14). The seal material flows via the transfer channel (16) into at least one cavity portion of an injection mold assembly to form at least one rings (15) of seal material. An abrasion chain link comprises at least one rivet hole (14). A transfer channel (16) is provided next to the rivet hole (14).

Abstract: A chainsaw cutting link (1b) comprises a cutting tooth (7b) with a side plate (12b) and a top plate (10b), defining an L-shaped cutting edge (13b, 14b). The top plate (10b) comprises an outer surface (11b) with a first outer surface portion and a depressed second outer surface portion (16). A saw chain comprises a plurality of such cutting links (1b). Use of such cutting links (1b) or such a saw chain increases the ability of making bore cuts. A method of manufacturing a cutting link (1b) comprises: punching a piece of material to form a cutting link (1b) blank with a top plate portion (10b) and a side plate portion (12b); bending the top plate portion (10b) to form an L-shaped cutting edge (13b, 14b); and grinding thereof. An area of the top plate (10b), corresponding to the second outer surface (16) is depressed.

Abstract: A cutting chain (300) for a chainsaw (100) may include a plurality of drive links (310) and a plurality of side links (320). The drive links (310) are arranged to lie in a plane parallel to a plane in which a guide bar (120) about which the chain (300) is rotatable lies. The side links (320) are operably coupled to respective ones of the drive links (310) and are oriented to lie in respective planes substantially parallel to the plane. At least some of the side links (320) include cutting portions. The drive links (310) and side links (320) are attached to each other by rivets (360), and the rivets (360) have a longitudinal length that is less than or equal to a width of the side links (320) in a transverse direction.

Abstract: The invention relates to a saw chain depth gauge filing template (1), comprising a first flat section (2) and a second flat section (3), wherein both sections (2, 3) are made from a single piece of flat metal, especially from sheet metal, wherein the first flat section (2) has a first bearing surface (4) for a cutter link edge (5) of a saw chain (6) to be filed, wherein the second flat section (3) has second bearing surfaces (7) for a drive link (8) of the saw chain (6), wherein the second surfaces (7) are established by an linear edge (9) in which at least two incisions (10, 11; 10, 11) are machined, wherein the second flat section (3) has at least one cutout (12, 12) for a part of the saw chain (6) to be sharpened by filing. Furthermore, the invention relates to a method for sharpening a saw chain by using such a saw chain depth gauge filing template. By the proposed concept filing of a saw chain becomes possible in a more precise way.
