  • Training of the knife as a fillet knife requires that with manual operation of the belt slicer pro Cutting process only a small part of the top layer can be removed.
  • EP 0773 089 A1 discloses a manually movable belt slicer suitable for pushing operation known.
  • the base body is used to remove the cover layer or part of the Cover layer of the conveyor belt is not moved over the conveyor belt, but along its end face.
  • a knife in the form of a thin blade is held out in the base body, the free end of which is bent upwards.
  • a hold-down is also mounted in the base body, which, leading the blade during the cutting process, rests on the top layer of the conveyor belt.
  • DE-GM 8702 754 describes a device for removing the cover layer or a part the top layer of a conveyor belt known. It is not a tool but a tool a mechanical device with the possibility of longitudinal grooves in an already vulcanized Introduce conveyor belt. It is important to ensure that a precisely defined Depth, width and profile of the groove is generated in the tape cover layer. To an unlimited length To be able to edit strip strips, the conveyor belt is relative to the stationary cutting device emotional. This has a stationary holder for a blade. The blade is U-shaped, the free ends of the two legs of the blade are mounted in the holder.
  • the task is solved with a manually movable belt slicer of the type mentioned at the beginning in that the knife is designed as a thin blade with a curved cutting edge, the Blade a central area, the cutting edge portion parallel to the bearing surface of the Base body is arranged and oriented perpendicular to the direction of movement of the belt plane as well two lateral areas, their cutting edge sections, starting from the cutting edge section of the central area, are angled into the opening of the base body.
  • the belt slicer according to the invention is its basic mode of action in that that its basic body is moved over the top layer of the conveyor belt, in Combination with the concrete design of the knife as a thin blade with curved on both sides separate cutting edge sections. -
  • the conveyor belt ensures that those introduced into the belt slicer via the handle Forces are introduced directly into the blade, which means there are no tilting moments in the belt slicer be initiated, as in a belt slicer with the other function type, at which the main body is guided next to the conveyor belt. Consequently the belt slicer according to the invention also does not require a hold-down device.
  • the inclined knife passes through an opening in the base body and the special one
  • the blade can be used to create a top layer with a belt plane per working stroke Cross section are removed from the conveyor belt, which is limited by the cross-sectional area of the blade the contact surface of the base body corresponds.
  • the blade should be in one central area Be arranged at an angle to the contact surface of the base body, which essentially corresponds to the angle, under which the pressure force for actuating the belt slicer is introduced into the handle.
  • This angle is expediently 5 ° to 15 °, preferably 7.5 ° to 12.5 °, in particular 10 °.
  • the blade is symmetrical is trained. Regardless of this, the cutting edge section of the respective side Range of the blade at an angle of 90 ° to 120 °, preferably 100 ° to 110 °, for Cutting edge portion of the central region of the blade may be arranged.
  • the blade itself starting from the Cutting edge, is flared.
  • the angle between the the cutting edge of the cutting edge of the blade advantageously 15 ° to 25 °, preferably 17.5 ° to 22.5 °, especially 20 °.
  • the cutting edge of the blade facing away from the base body is particularly oriented parallel to the contact surface of the base body.
  • the belt slicer additionally with a guide device is connected to the lateral contact on the end face of the conveyor belt serves.
  • the guide device is preferably designed as a bar that with the base body connected is. It should be adjustable relative to the body.
  • the manually movable belt slicer 1 has a plate-shaped, elongated, in the manner of a cuboid trained base body 2, with a U-shaped handle 3 in the region of its ends connected is.
  • screws 4 pass through the base body 2, which are in the legs 5 of the handle 3 screwed in.
  • the base body 2 has on the side facing away from the handle 3 a flat support surface 6.
  • the base body 2 is in the region of its half length an opening 7, which passes through a knife, which is designed as a thin blade 8.
