Patent number: 8968056Abstract: The system for machining the bottom of skis comprises a machine frame, in which a ski is stationary supported by roller carriers. The machining is performed by machining tools on a carriage, which extends throughout under the ski. During the machining, the carrier rollers that are alternately arranged behind each other, take over the support of the ski. There are always so many carrier rollers directly under the ski that its bottom remains in a stationary position.Type: GrantFiled: September 6, 2012Date of Patent: March 3, 2015Assignee: Spuhl AGInventors: Mario Reut, Patrick Jung

Patent number: 7198558Abstract: A dressing device (10,90) for sharpening or conditioning of a blade (18) or the like includes one or more disk pairs (36–40,108), each having a pair of disks (52,54,110,112) respectively presenting a series of circumferentially spaced, projecting teeth (64) with openings (66) therebetween. The disks (52,54,110,112) are oriented in face-to-face relationship with the teeth (64) thereof in meshed, intercalated relationship to thereby create circumferential dressing openings (76,122). The dressing surfaces (74) of the teeth (64) are of arcuate, concave configuration so as to create a desirable gothic-arch edge on a blade (18) or the like.Type: GrantFiled: March 18, 2005Date of Patent: April 3, 2007Assignee: Hantover, Inc.Inventor: Clark A. Levsen

Patent number: 6846228Abstract: A structure for a polishing machine of an optical disk, which comprises a motor, a turntable unit integrated with a housing, at least two polishing wheel positioned on a cover which can cover up the housing, and a timer. When the cover is closed, the polishing wheel can polish the optical disk. The primary objective of this invention is to provide a structure for a polishing machine with a precise polishing effect and higher automation to increase the quality of polishing. The secondary objective of the present invention is to provide a structure for a polishing machine which is simplified in structure, miniaturize in volume and is easily stored and used.Type: GrantFiled: July 29, 2002Date of Patent: January 25, 2005Inventor: Ming-Sheng Lin

Patent number: 6290582Abstract: The invention relates to a sharpening device for sharpening cutting edge tools and the like, comprising two sharpening elements arranged, at a distance from each other in the axial direction, for rotation on a shaft extending along a center axis common to the sharpening elements. The sharpening elements have arms extending radically outwards from the shaft, said device being characterized in that the sharpening elements are arranged relative to each other in such a way, that their respective arms are inclined towards each other so that they intersect their respective paths of rotation, the arms, then, coming from a respective of the two sharpening elements, in an alternating way.Type: GrantFiled: February 16, 2000Date of Patent: September 18, 2001Assignee: Telefonaktiebolaget LM EricssonInventor: Tore Eklund

Patent number: 5609512Abstract: An apparatus and method for honing, sharpening or grinding a curved peripheral cutting surface of a slicer blade are provided. Included is the use of one of a set of interchangeable cams that generally follows the curved shape of the blade cutting surface, whether same has a constant radius or varying radii. In order to minimize downtime and sanitation operations, the honing is accomplished off-line of the slicer equipment. Preferably, the slicer blade remains perfectly flat during honing, and the movement of one or more honing or grinding wheels is closely controlled so as to provide honed or ground cutting edges which are of substantially uniform width throughout their respective peripheries. Honing is accomplished in accordance with objectively measured sharpness standards by which superior sharpness levels are attained.Type: GrantFiled: January 9, 1995Date of Patent: March 11, 1997Assignee: Kraft Foods, Inc.Inventors: Terry L. Holmes, Gary R. Skaar, Larry C. Gundlach, Dennis G. Flisram
