| 20120247295 | Ultrasonic Trimming Appratus - An ultrasonic trimming apparatus is composed of an articulated robot, a cutting apparatus, and a grindstone. The cutting apparatus is composed of an ultrasonic oscillator supported by the end portion of the robot, a cutter blade which is supported by the ultrasonic oscillator, and a workpiece securing portion which secures a workpiece. The grindstone is disposed within the movable range of the cutter blade driven by the robot and is placed in a position at which the cutter blade can pressure contact the cutter blade. The cutter blade is ultrasonically vibrated by the ultrasonic oscillator and is ground while being pressed against the grindstone by means of the articulated robot. The ultrasonic trimming apparatus efficiently cuts a sheet material composed of soft material such as plastic, fabric, or rubber, a composite material, or a material containing glass fiber even when the material has a three-dimensional shape. | 10-04-2012 |
| 20130276606 | CUTTING TOOL HEAD FOR MULTI-PLY FABRIC CUTTING MACHINE - A cutting tool head for a sheet material cutting machine has a pressure foot mounted by way of linear actuators operable to independently move the pressure foot vertically relative to an eccentric drive mechanism and a knife assembly of the tool head. The knife assembly includes a support shaft driven by the eccentric mechanism, a blade connected to the support shaft, and a splined shaft between the support shaft and blade The splined shaft slides in a splined bushing, and the eccentric mechanism drives reciprocating motion of the support shaft, the splined shaft, and the blade relative to the splined bushing. The splined bushing is rotatable to rotate the splined shaft and blade. A blade sharpener of the tool head has a sharpening disc backed by a magnetic disc to attract the blade into evenly distributed contact with the sharpening surface, and to retain metal shavings on the sharpening disc. | 10-24-2013 |
| 20140090532 | DRESSER DRIVE LINK FOR SAW CHAIN - Embodiments herein provide a drive link having a conditioning portion to be used in conjunction with one or more dresser links of a saw chain to condition a sharpening element. The dresser links may include left and right dresser links configured to contact the sharpening element in first and second contact regions which may not overlap, leaving a gap. The conditioning portion of the drive link may contact the sharpening element in a third contact region that includes at least a portion of the gap between the first and second contact regions. | 04-03-2014 |
| 20140137716 | DRESSER LINK FOR SAW CHAIN - Embodiments herein provide a dresser link for a saw chain that is configured to condition a sharpening element. The dresser link may include a conditioning element with an outer edge that is offset from an outer side of the dresser link. The conditioning element may include a horizontal relief angle and/or a vertical relief angle. The saw chain may further include a cutter link having a cutting element. The horizontal and/or vertical relief angle may facilitate maintenance of a clearance between the cutting element and the conditioning element after wear of the cutting element and conditioning element. | 05-22-2014 |
| 20140331838 | BLADE SHARPENING SYSTEM FOR A LOG SAW MACHINE - A blade sharpening system for log saw machines is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply a dynamically cushioned pressure between the grinding wheels and the cutting blade. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade. | 11-13-2014 |
| 20150047486 | QUICK CHANGE ABRASIVE WHEEL FOR RECIPROCATING KNIFE SHARPNER - A spindle configured for a reciprocating knife sharpener is provided. The spindle includes a head including an arbor configured for manual exchange of abrasive material. A knife sharpener and a cutting table are disclosed. | 02-19-2015 |
