Definitions

  • the invention is in the field of cutlery, and its object is a relief of a tool blade sharp, knife in particular.
  • microdentures which are composed of a plurality of curved generative surfaces parallel, called microbevels, defining with one of the lateral faces of the blade a plurality of micro-cutting edges respectively.
  • GB-A-391.947 (THORPE) describes a knife having a blade provided on each of its faces of several pluralities of so-called short microbevels, said pluralities being distant from each other; the said pluralities of microbevels have equal lengths, the distance separating the pluralities of short microbevels is equal to the length of the pluralities of short microbevels.
  • microdentures usual, formed by a plurality of short microbevels formed along the blade, lies in the fact that the short microtrancants obtained form a toothing which induces shredding of the material to be cut, the tool thereby relatively no longer cutting, and ultimately being of a delicate use when the material, meat in particular, is flexible.
  • the result obtained is satisfactory as for improving the performance of the tool for cut the material, but keep another general disadvantage of micro-dentured tools, namely make their use difficult due to the presence of microbevels which induce a tendency of the blade to tilt pivotally around its wire towards the face microbiseautée.
  • the object of the invention is to propose a relief, of the microdenture type, for a tool blade sharp, knife in particular, which remedies problems mentioned above, giving the tool an optimal performance of cutting and a rigorous natural balance during its use.
  • microdenture including microbevels short and long microbevels on one side of the blade are preferably offset from those formed on the other side of the blade, that is to say that at one plurality of short micro-cutters formed on one of the faces of the blade corresponds to at least one long cutting edge formed on the other side of the blade, so that each said cutting spaces comprises short microbevels and at least one long microbevel respectively and on the other side of the blade wire.
  • a relief of a sharp tool blade, knife especially, includes the features of claim 1.
  • a knife blade is provided on one of its faces 2 with a microdenture extending along its thread, the so-called microdenture being composed of separate and alternate microbevels 4 and 6 of different length, which define with side 2 of the blade a plurality of micro cutting edges 8 and 10 in length respectively.
  • the median longitudinal axis A represents an axis of reversal of the blade, the two views on either side of this axis illustrating a respective face of the latter.
  • range P the grouping of neighboring microbevels of the same type, that is to say long, such as 4 or even 5, or short, such as 6 or even 7, and by cutting space E each successive sequences comprising both a plurality of short microbevels 6,7 and at least one long microbevel 4,5.
  • the blade comprises, arranged on each of its lateral faces 2 and 12, a succession of microbevels 4, 6 and 5.7 alternating of different length, that is to say short and long.
  • the areas P of short microbevels and of long microbevels are preferably offset from one face to the other, as illustrated in FIGS. 2 to 7.
  • the areas P of microbevels project from the general orientation of the blade wire, while in FIGS. 3 and 6, the tracks P are set back with respect thereto, and that in FIGS. 4,5,7 and 8, the ranges P are aligned.
  • a range P of long microbevels 5,4 on one side face of the blade corresponds to a portion P ' of beach with short microbevels 6,7 on the other side face of the blade, unlike the other embodiments of the relief of the invention illustrated, in which a range of long microbevels 4.5 on one side face of the blade corresponds to an equivalent range of short microbevels 6.7 on the other lateral face of the blade.
  • range types can be greater than of them; for example, to a long microbevel formed on one of the sides of the blade can correspond to two ranges of short microbevels of different length, or even a alternating short microbevels of different length; in in other words, a range of short microbevels can be composed of at least two types of short microbevels of respective and different lengths.
  • a range of short microbevels which can itself be composed of short microbevels of different lengths, may correspond to a range of several long microbevels, which can itself be composed of long microbevels of different length.
  • the length of the areas P of short microbevels and long microbevels formed on one of the lateral faces of the blade and the length of the areas P of short microbevels and long microbevels formed on the other face of the blade can be either identical or different; in other words, a first alternation of short microbevels and long microbevels formed on one of the faces of the blade corresponds to a second alternation of short microbevels and long microbevels formed on the other face of the blade, the so-called first and second half-waves can be either different or identical, and in the latter case be offset one hand relative to the other, said offset being able to be arranged on the blade so that at least one microbevel long one of the faces of the blade corresponds to a plurality of short microbevels on the other side of the blade (fig. 2 to 6), or so that at least one long microbevel of one of the faces of the blade corresponds to both a plurality of short microbevels and at least
