Definitions

  • the invention relates to a cutting device for cutting sheet material, such as paper or films, having the features of the preambles of claims 1 and 10.
  • manually operable cutters are used both in the office and in the private sector, which essentially consists of a sheet support in the form of a sheet material usually completely receiving backing plate and a mostly on one side consist of the pad plate arranged cutting device.
  • lever cutting devices and roll cutting devices have prevailed.
  • the latter have a straight guide rail running above and parallel to the base plate, on which a roller cutting device in the form of a knife carriage can be moved.
  • rotatably mounted disc diameter is arranged, which by means of an actuating device from a raised starting position in a lowered cutting position is movable.
  • the cutting process is effected in that the knife carriage is moved after taking the cutting position by the disc knife along the guide rail.
  • the cutter overall remains stationary (see. US 2002/00923696 A1 ; DE 203 18 947 U1 ; DE 10 2004 004 081 A1 ; DE 203 17 096 U1 ).

  • the roll cutting device can be moved on the base plate and thus relative to the sheet material to be trimmed (cf. FIGS. 7 and 8th of the EP 1 475 201 A1 ).
  • the cutting device consists only of a set with a cutting mat, an acrylic glass ruler and a slitter, which has a mounted on the acrylic glass guide rail and a supply of three independent slitter, in each of which a disc knife is mounted, which are different Have cutting.
  • the sheet material to be trimmed is placed on the cutting mat.
  • the slitter is pushed with the desired disc diameter on the guide rail from the front side and the unit is made of acrylic glass, guide rail and slitter by moving over the sheet material in the desired position for the trim.
  • the cutting operation is effected by the fact that the housing of the roller cutting device with the disc blade in the direction of the sheet material and thus pressed down in the cutting position and then the roll cutting device is moved along the guide rail. So that it does not come to a relative movement of the acrylic glass ruler against the sheet material, while the acrylic glass ruler must be firmly pressed onto the sheet material, which is cumbersome and shifts not reliably avoided.
  • the change of the disc diameter takes place in that the roller cutting device located on the guide rail is replaced by another with the desired disc diameter.
  • the known cutters have the fundamental disadvantage that the respective cutting line is determined by the position and course of a guide rail. In addition, all cutters of this type take up considerable space, so that their transport is cumbersome and they have a significant amount of space.
  • the invention has the object of providing a cutting device having a slitter having a single slitter with one or more disc knives, form such that with the cutter any cutting lines can be realized. In addition, it should have a small space requirement.
  • This object is achieved in a cutting device with a single disc diameter by the features of the characterizing part of claim 1 and in a cutting device with a plurality - for example, two, three or four - Slicing knife having cutting device solved by the features of the characterizing part of claim 8.
  • the basic idea of the invention is to design a cutting device such that the cutting process can be effected by allowing the cutting device as a whole to move freely over the sheet material with the disc knife fixed downwards relative to the cutting device, without the movement being guided by a guide device how the guide rails is limited in the known cutters of the type in question here. You can not only produce straight cutting lines with this cutter, but move it in any direction. This opens up the possibility to cut out certain areas of a sheet material, for example, to separate photos from desired sections in a single operation. This results in a variety of creative possibilities that could not be realized with the known cutters.

  • Each disc knife should be completely covered on the outside via a removable cap in the starting position.
  • the protective element may be formed, for example, as the underside of the cutter forming protective disc, which is preferably spring-loaded in the direction of the protective position. In this way, it is ensured that the relevant disc knife is encapsulated at least on one side when the cutter is lifted from the sheet and transported. If the spring load is greater than the weight of the cutter without the protective element, it is also guaranteed that the protective position of the protective element is maintained even when the cutter rests with its underside on the sheet material or other surfaces.
