| 157013000 | GROOVING, SLITTING AND/OR LACERATING OF RUBBER TIRES | 8 |
| 20100300626 | PNEUMATIC TIRE TREAD - A pneumatic tire tread has tread elements formed by circumferential and/or lateral grooves. At least one tread element has a sipe that devolves from a constant width sipe having a three dimensional aspect in at least a portion of the radially outer portion of the sipe to a wider width groove at the base of the tread feature. | 12-02-2010 |
| 20100326603 | CORRECTION FOR ASYMMETRICAL BUFFING - Methods, apparatus and computer programs for correcting a buff of tread from a crown of a tire, the steps of the method including measuring the distance between the tire crown surface and the belt at each of the plurality of locations; calculating a projected distance between the crown surface and the belt at each of the plurality of transverse locations across the crown using proposed buff radii, choosing a new position of the buffing radius origin from the one or more proposed origin positions; and buffing the tread from the tire crown along the arc described by the buff radius having the buffing radius origin at the new position. | 12-30-2010 |
| 20110277942 | MACHINE FOR REGENERATION OF PNEUMATIC TYRES - There is described a machine ( | 11-17-2011 |
| 20120118512 | AIR COOLED SPACER FOR MULTI-BLADE ABRADING WHEEL - An abrading wheel such as a rasp hub for use in tire retreading machines includes two generally circular end, or side, plates with plural spaced mounting pins extending between and coupled to the two spaced plates. Rasp blades arranged in stacks which are arranged end-to-end about the wheel's circular circumference. Disposed between and engaging each pair of adjacent blades is a spacer, which is also attached to the mounting pins. Each spacer is curved lengthwise to match the curvature of the blades and includes plural spaced upper and lower recesses disposed immediately adjacent to its pair of adjacent blades to allow air to freely pass over the entire length of each blade as the hub is rotated at high speed to dissipate heat from the blades during operation for increased blade reliability and longevity. | 05-17-2012 |
| 20120145334 | Method and Device for Making Blind Grooves in an Unvulcanized Tread - Method of manufacturing a tire comprising a tread strip in which blind radial cuts are arranged in the blocks of rubber that form the tread pattern, comprising a step during which the cuts (33) are made in the unvulcanized tread strip (3) intended to cap the green tire. One or more blades (22) are raised to a temperature higher than the vulcanization temperature of the material of which the tread strip (3) is made are caused to penetrate the radially internal face (32) of the tread strip (3) for a sufficient period of time that they superficially vulcanize the walls of the cut in contact with the blade (22) so as to prevent the faces from sticking back together once the blade has been withdrawn from the cut. | 06-14-2012 |
| 20130292063 | Tire Tread Buffing Apparatus and Method - A system and method for removing an outer layer of resilient material from an object to achieve a target outer dimension includes performing an initial cut at a cutting depth to remove an outer layer of the material. A parameter indicative of a work input to a cutter that performed the cut is acquired and used to determine the cutting depth that will be used for performing a subsequent cut to remove an additional layer. In this way, subsequent cuts are performed until the target outer dimension is achieved. | 11-07-2013 |
| 20160046091 | CUTTER, CUTTER SYSTEM, AND METHOD FOR SEVERING ELASTOMERIC MATERIAL FROM NON-PNEUMATIC TIRE - A cutter may be configured to sever elastomeric material of a non-pneumatic tire. The cutter may include a mounting fixture configured to be operably coupled to an actuator, and a guide associated with the mounting fixture. The guide may include an elongated rod like member having a longitudinal axis. The cutter may further include a blade configured to sever the elastomeric material, wherein the blade is operably coupled to the guide and extends along the longitudinal axis of the guide. The blade may have a cutting edge remote from the mounting fixture. | 02-18-2016 |
| 20160046092 | CUTTER, CUTTER SYSTEM, AND METHOD FOR SEVERING ELASTOMERIC MATERIAL FROM NON-PNEUMATIC TIRE - A cutter system configured to sever elastomeric material of a non-pneumatic tire may include a cutter including a mounting fixture and a blade coupled to the mounting fixture. The cutter system may further include a driver assembly operably coupled to the mounting fixture of the cutter. The driver assembly may include a support member, and a cross-member operably coupled to the mounting fixture and the support member. The driver assembly may further include a first actuator operably coupled to the cross-member and the mounting fixture of the cutter, wherein the first actuator is configured to rotate the mounting fixture of the cutter relative to the cross-member. The driver assembly may further include a second actuator operably coupled to the cross-member and the support member, wherein the second actuator is configured to move the cross-member, such that the cutter reciprocates along a first axis relative to the support member. | 02-18-2016 |
