Definitions

  • the invention relates to a manually movable Gurthobel for removing the cover layer or a part of the cover layer of a conveyor belt, with a belt body having a flat support surface and on which a handle is attached and mounted with a base body, arranged inclined knife, which passes through an opening in the body.
  • Such manually movable Gurthobel are basically known and serve to the cover layer or remove parts of the cover layer at the end of a conveyor belt. It is here common to secure the strap end on a support against slipping and then the processing with the planer, whereby the planer is pulled by hand.
  • the structure of the Gurthobels resembles a joiner's plane, which is led by hand.
  • the Gurthobel lies with its flat support surface on the conveyor belt, wherein the inclined, Down over the support surface protruding knife cut away cover sheet strips, leaving wavy Recesses in the conveyor belt arise.
  • a manually movable Gurthobel of the type mentioned is known from DE-PS 11 12 279.
  • the knife is designed as a stable choker, the cutting edge in one lying on the plane of symmetry of the knife cross-section perpendicular plane, with the knife outside includes an acute angle, outside the cutter head two more, against the knife back towards diverging cut edges are provided, which also in a lie the plane of symmetry of the knife cross-section perpendicular plane, but with the The back of the knife forms an acute angle that opens backwards.
  • a Gurthobel can only produce grooves in the top layer of the conveyor belt. Training of the knife as a chopper conditionally that with manual operation of Gurthobels pro Cutting process only a small part of the topcoat can be removed.

  • a hold-down is additionally stored, the, the blade during the cutting process leading rests on the cover layer of the conveyor belt.
  • From DE-GM 8702 754 is a device for removing the cover layer or a part the cover layer of a conveyor belt known. It is not a tool but tools to a machine device with the possibility of longitudinal grooves in an already vulcanized To bring in conveyor belt. This is to ensure that a well-defined Depth, width and profile of the groove is produced in the band cover layer.
  • the conveyor belt is relative to the stationary cutter emotional. This has a stationary support for a blade.

  • a U-shaped designed blade use with the free ends of the two legs of the blade in a holder a knife carriage are attached.
  • the knife carriage is driven by a winch. This high translations are effective, so it is necessary, a relatively thick and to provide robust training of the knife blade.
  • the required mechanical effort is included this device considerably.
  • It is an object of the invention is a manually movable Gurthobel of the type mentioned to further develop that with this with a small amount of force relatively large proportion of Cover layer or a part of the cover layer can be removed from the conveyor belt, wherein ensured is that the cutting forces optimally from the Gurthobel over the blade into the conveyor belt be initiated.
  • the problem is solved with a manually movable Gurthobel of the type mentioned in that the knife is designed as a thin blade with a curved cutting edge, wherein the Blade a central area, the cutting edge portion parallel to the bearing surface of the Arranged base body and is oriented perpendicular to the direction of movement of the Gurthobels and two lateral portions, the cutting edge portions, starting from the cutting edge portion of the central region, are angled into the opening of the base body, wherein the blade held in its central region between the base body and a clamping plate is.
  • the blade should be in its central area under one Be arranged angle to the bearing surface of the body, which corresponds substantially to the angle, under which the pressure force for actuating the Gurthobels is introduced into the handle.
  • this angle is 5 ° to 15 °, preferably 7.5 ° to 12.5 °, in particular 10 °.
  • the blade is symmetrical is trained. Regardless thereof, the cutting edge portion of the respective lateral should Area of the blade at an angle of 90 ° to 120 °, preferably 100 ° to 110 °, for Cutting edge portion of the central portion of the blade can be arranged.
  • the blade itself starting from the Cutting edge, conically widened is formed.
  • the angle between the on the cutting edge adjoining cutting edges of the blade expedient 15 ° to 25 °, preferably 17.5 ° to 22.5 °, in particular 20 °.
  • the base body facing away from the cutting edge of the blade is oriented in particular parallel to the bearing surface of the body.
  • the guide device is preferably designed as a bar, which is connected to the main body connected is. It should be adjustable relative to the base body.
  • the manually movable Gurthobel 1 has a plate-shaped, elongated, in the manner of a cuboid trained basic body 2, with the in the region of its ends a U-shaped handle. 3 connected is.
  • screws 4 penetrate the main body 2, in the legs 5 of the handle 3 screwed itself.
  • the base body On the side facing away from the handle 3, the base body second a flat bearing surface 6.
  • the base body 2 with an opening 7 which passes through a knife, which is formed as a thin blade 8 passes.
  • “thin” is understood here as a starch, as it is realized, for example, in carpet blades is.
  • the blade has a curved cutting edge 9. It has a central area, whose Cutting edge portion 10 arranged parallel to the support surface 6 of the base body 2 and perpendicular is oriented to the direction of movement X of the Gurthobels 1 and two lateral areas whose Cutting edge portions 11 and 12, starting from the cutting edge portion 10 of the central region, are angled into the opening 7 of the base body 2 into it.
  • the cutting edge portions 11 and 12 of the respective lateral region of the blade 8 under a Angle of about 105 ° to the cutting edge portion 10 of the central portion of the blade eighth arranged.
  • the blade 8 is at an acute angle to the bearing surface 6 of the main body. 2 positioned.
  • the base body 2 on its side facing the handle 3 with a in the exemplary embodiment at an angle of 10 ° to the support surface 6 inclined receiving surface 13 provided for the blade 8.
  • the blade 8 is fixed by means of a clamping plate 14, which on the Blade 8 acts in its central region and presses against the base body 2.
  • braced is the clamping plate 14 with the base body 2 by means of a screw 15, the clamping plate 14th penetrated and screwed into a thread 16 of the base body 2.
  • the blade 8 can be so in fix different positions by means of the clamping plate 14, with the result that, accordingly the requirements, the cutting edge 9 in the region of the central cutting edge portion 10 more or less to the bearing surface 6 of the base body 2 is spaced.
  • the blade 8 is formed in the region of the cutting edge 9 so that they, starting from the Cutting edge 9 conically widened.
