20130305896 | CUTTER DIES - A cutter die has an upper body and a lower body having first and second cutting blades which encapsulate a rope. A first blade holder retains the upper body and a second blade holder retains the lower body. The first blade holder has an edge for supporting the wire rope and the second blade holder has an edge for supporting the wire rope. The first cutting blade and the second cutting blade can have cutting edges which are cantered and offset. | 11-21-2013 |
20140116223 | CUTTING APPARATUS - In a first aspect there is provided a cutting apparatus for cutting material by a shearing action. The cutting apparatus comprises a first arm comprising a first cutting blade and a second arm comprising a second cutting blade. The second arm is operatively associated with the first arm and mounted relative to the first arm so as to define a cutting region between the first cutting blade and the second cutting blade in which cutting region a cutting operation of material is in use effected as a result of cooperation between the first cutting blade and the second cutting blade. At least one of the first and the second arm is operatively mounted so as to pivot about a pivot axis relative to the other arm. The second cutting blade is mounted to the second arm via a mounting region, the mounting region being laterally offset from the cutting region in a direction along the pivot axis such that cutting or shearing forces generated during a cutting operation cause the second cutting blade to be urged towards the first cutting blade. | 05-01-2014 |
20140123824 | SHEARING BLADE HAVING A BLADE INSERT - The invention relates to a shearing blade ( | 05-08-2014 |
20140182441 | CUTTER DIES - A cutter die has an upper body and a lower body having first and second cutting blades which encapsulate a rope. A first blade holder retains the upper body and a second blade holder retains the lower body. The first blade holder has an edge for supporting the wire rope and the second blade holder has an edge for supporting the wire rope. The first cutting blade and the second cutting blade can have cutting edges which are cantered and offset. A cutter tool has a first cutting blade and first retainer; a second cutting blade and a second retainer; and a cutting jaw assembly. The first and second cutting blades and said first and second retainers are secured to first and second jaws of jaw assembly and positive stops are formed on the first and second jaws. | 07-03-2014 |
20140326123 | Blade Device and System for a Mobile Shear - Disclosed is a system and method providing an improved blade design and arrangement for a mobile shear. The blades in the upper and lower jaws of the shear may be removable, reversible and interchangeable, thereby providing the user with the ability to increase the life of the blades by rotating them when excessive wear is realized on the exposed edges. | 11-06-2014 |
20140331843 | SYSTEM OF INDEXABLE CUTTING PORTIONS FOR A SHEAR - The present disclosure describes various embodiments, as well as features and aspects thereof, of a system, for a shear, of fully indexable cutting portions comprises at least one blade and a plurality of substantially identical indexable cutting portions. The at least one blade is configured to mechanically receive a plurality of indexable cutting portions. The plurality of substantially identical indexable cutting portions are arranged on the at least one blade to form a composite angled cutting edge. The composite angled cutting edge comprises at least one angle. Each indexable cutting portion comprises a coupling portion and eight edges. The coupling portion of each indexable cutting portion is configured to mechanically engage the indexable cutting portion to the at least one blade. | 11-13-2014 |
20150075347 | METHOD FOR PROVIDING AN ABRASION RESISTANT CUTTING EDGE AND TRIMMING DEVICE HAVING SAID CUTTING EDGE - A method for manufacturing a toothbrush filament trimmer includes providing a cutter and a counter knife each comprised of hot-working steel, wherein the cutter and the counter knife include at least a recess suitable to carry a coating to form a cutting edge; depositing a first material onto the at least one recess of the cutter and/or the counter knife to form a first layer; depositing a second material onto each first layer to form a second layer, wherein at least a carbide of at least one element of the fourth, the fifth, the sixth and/or the seventh group of the periodic table is used as the second material; and sharpening the coating comprising the first layer and the second layer applied to the at least one recess of the cutter and/or to the at least one recess of the counter knife, wherein a cutting edge is formed. | 03-19-2015 |
