  • the protection has layers of elastic material, between which movable, small protective elements are arranged.
  • the invention has for its object to provide a cut protection, which has a simple structure and offers a good protection against cuts when working with a manually operated saw.

  • the first protective layer 71 rests on a spacer layer 23.
  • the first protective layer 71 is formed by a continuous, flat textile material and not by individual juxtaposed strips of material.
  • the first protective layer 71 comprises a carrier material 69, which advantageously forms a planing protection and on which a smooth layer 31 is arranged.
  • the structure of the individual layers corresponds to that of the FIGS. 4 and 5 described structure.
  • the cut protection 61 has between the two seams 3 in the edge region 20 of the protective layers 20, 71, 23 further seams 63. In the embodiment, two seams 63 are provided.
  • seams 63 may be advantageous.
  • the seams 63 extend in the transverse direction of the cut protection 61. Additionally or alternatively, seams can also be provided in the longitudinal direction of the cut protection 61.
  • Adjacent seams 3, 63 have a distance o to each other. The distance o is at least 1.0 cm, in particular at least 3.0 cm. The distance o is selected so that the elasticity of the outer protective layer 22 is sufficient to brake a tool when it engages the cut protection 61 in the working direction.
  • the seams 3, 63 connect all the protective layers 22, 71, 23 of the cut protection 61 with each other. However, it may be advantageous to provide, in addition to or as an alternative to the seams 63, seams which connect only the protective layers 71 and 23 with each other.
  • a protective layer is to be understood as an individual material layer which is present in terms of substance and which may be formed integrally from a plurality of components.
  • a coating or paint that forms the smooth, slippery surface 26 forms a single protective layer with the substrate 19 to which the coating or paint is applied.
