| 083661000 | Endless band or belt type | 11 |
| 20080202306 | Workpiece Cutting Method and Band-Saw Machine - A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade ( | 08-28-2008 |
| 20080276781 | Cutting tool - Cutting tool having a support and a multiplicity of saw teeth which have a tip region and a root region, wherein the saw teeth are welded directly or indirectly to the support at the root region, and wherein the tip region is narrower than the root region in side view. | 11-13-2008 |
| 20110017042 | Saw Blade Including Teeth Having a Chip Deforming Element - A saw blade ( | 01-27-2011 |
| 20110132168 | BAND SAW BLADE - A band saw blade includes multiple saw teeth having a straight tooth and right and left set teeth, and also includes a gullet portion provided between the saw teeth. A rake surface of each of the saw teeth is provided with a chip curler portion formed into an arc shape at an entire range of approximately 90° to form a chip generated at the time of cutting a work into a small rolled shape before the chip comes into contact with a bottom portion of the gullet portion. A chip non-contact surface to be kept out of contact with the chip is formed to have either a flat surface or a convex surface between the chip curler portion and the bottom portion of the gullet portion, and a dent portion is formed between the chip non-contact surface and the gullet bottom portion, the dent portion recessed from the chip non-contact surface in an opposite direction to a moving direction of the band saw blade in order to increase a radius of a concave curved surface constituting a back side of the gullet bottom portion. A flat portion for dispersing stress concentration is provided at an innermost portion of the gullet portion. | 06-09-2011 |
| 20110265627 | BAND SAW BLADE HAVING NUB-LIKE PROTRUSIONS - The saw blade according to the invention comprises a plurality of teeth spaced apart from each other by chip spaces, wherein at least some chip spaces have pimple-shaped bulges. | 11-03-2011 |
| 20120017742 | Saw Band and Method for the Production of a Saw Band - A saw band of steel for a band-sawing machine has a band back and a row of teeth having a number of teeth, at least the row of teeth being provided with a hard material coating. According to the invention, this coating comprises one or more metals of subgroups IV, V or VI of the periodic system or aluminum or silicon and/or their nitrites, oxides, carbides, carbonitrides or borides of the aforementioned metals or mixtures thereof. A method according to the invention is a vacuum coating method, for example as PVD or paCVD. | 01-26-2012 |
| 20130133500 | METHOD FOR MANUFACTURING BANDSAW BLADE, AND BANDSAW BLADE - A method for manufacturing a bandsaw blade provided at the top of the teeth with cutting tips made of a hard material, includes the steps of: offsetting to the left and right saw teeth constituting left and right offset teeth; forming the saw teeth constituting the left and right offset teeth to a smaller tooth height than that of the saw teeth constituting straight teeth; and grinding cutting tips provided to the top of the left and right offset teeth subsequent to the offsetting step, and machining the edge lines at the top of the left and right offset teeth so that the lines are orthogonal to the travel direction of a bandsaw blade and the cutting direction of the bandsaw blade. | 05-30-2013 |
| 20130298743 | Saw Blade Including a Cutting Element Made by Powder Metallurgy - A saw blade ( | 11-14-2013 |
| 20140102276 | Composite Saw Blades - Saw blades, including band saw blades, reciprocating saw blades, hole saw blades and hand hack saw blades, are made from a bi-metal strip. The bi-metal strip includes a cutting edge defined by a plurality of cutting teeth that is welded to an axially-elongated carbon or spring steel backing. The cutting edge is formed of a high speed steel alloy consisting essentially of: about 8/10% to about 1% carbon, up to about 45/100% silicon, up to about 4/10% manganese, up to about 3/100% phosphorous, up to about 3/100% sulfur, about 4% to about 6% cobalt, about 3% to about 5% chromium, about 4-1/2% to about 5-1/2% molybdenum, about 1% to about 2-1/2% vanadium, about 5-1/2% to about 7% tungsten, and about 74% to about 78-1/2% iron. | 04-17-2014 |
| 20140150620 | Saw Blade Having Different Material Teeth and Method of Manufacture - A saw blade having a blade body, a plurality of cutting teeth defining a cutting edge along an edge of the blade body, each tooth along the cutting edge defining a cutting tip. At least one tooth tip along the cutting edge includes a different material, such as, for example, high speed steel, carbide, diamond, and/or a tip coating, than at least one other tooth tip along the cutting edge. The plurality of teeth may be arranged in a repeating pattern or in no pattern along the cutting edge. A method of manufacturing the saw blade includes forming a cutting edge along an axial edge of a blade body, defined by a plurality of cutting teeth having respective tooth cutting tips, wherein at least one tooth tip along the cutting edge includes a different material than at least one other tooth tip along the cutting edge. | 06-05-2014 |
| 20150075346 | Saw Band With a Profiled Back - A saw band ( | 03-19-2015 |
