Definitions

  • the problem with the present invention was to solve the following problem:
  • the plastic strip itself had to be shaped in such a way that it had a tight fit in the groove. This means that on the one hand it was not allowed to have too much leeway, but on the other hand that it had to be easy to push in by hand.
  • this problem is solved in such a way that the plastic strip is shaped like a snake, or more precisely, sinusoidally.
  • this serpentine shape is then forced into a straight line.
  • the plastic strip exerts pressing forces on both sides of the groove and is thereby firmly clamped in it.
  • FIGS. 1 and 2 The shape of the newly created cutting bar can be seen in FIGS. 1 and 2. From these two figures it can be seen that the new cutting bar practically only consists of a thin film, which in the middle with a tube-like structure connected is. The width of this cutting bar or better cutting foil remains the same as the old cutting bar, namely approx. 10 mm. However, it is significantly thinner in thickness, so that one can now speak more of a film. So that these new cutting strips or cutting foils can be inserted into the groove of the existing paper cutting machines, a metal strip 4 is glued into the existing groove. This metal bar 4 has in the middle according to FIG.
  • the cutting bar can be used twice by simply turning it over.
  • This new strip is no longer PVC, but a notch-resistant plastic e.g. Polypropylene or a high molecular weight polyethylene is used.
  • a notch-resistant plastic e.g. Polypropylene or a high molecular weight polyethylene is used.
  • cutting strips of different hardness are no longer produced, but only one with a special Shore hardness, while until now different types were produced.
  • the new hardness would also no longer be easily achievable with PVC, because it lies between the soft and hard PVC, so you would have to provide the hard PVC with a plasticizer for this purpose, so that the hardness is no longer under control would have.
  • With the new cutting bar you have a product that is suitable for all known knives.
  • this new cutting bar was also simplified. While the old one had to be brought to the required sinus shape in the heating furnace after cooling, cutting to length and grinding on a special grinding machine (4-surface machining), this new bar no longer needs any reworking. You can also do without the disadvantageous grinding. The cutting bar is therefore only extruded. You can use dimensioned extruders; a high surface quality is achieved at the same time. So it can sharp knives can no longer be damaged by remaining hard grindstone particles.
  • the thickness of the cutting bar By reducing the thickness of the cutting bar to a minimum, one not only achieved that the material costs could be reduced, but at the same time ensured that absolute dimensional accuracy and high surface quality can be guaranteed, which prevents individual blades from getting stuck Moving stacks of paper back and forth makes it unimaginable.
  • the relatively small dimensions mean that the absolute linear expansion due to temperature fluctuations and moisture absorption is minimized. It must be taken into account that the coefficient of thermal expansion is greater for plastics than for metals, from which e.g. the work table is made.

Abstract

La baguette en matière synthétique est utilisée pour protéger le dessus d'une table en prévoyant que le couteau n'entre pas en contact avec le dessus de la table, mais avec la baguette. Cette baguette est très mince et comprend un appendice tubulaire. Elle ne présente pas les inconvénients des baguettes connues et a comme avantage de garantir une plus grande précision, une fabrication plus simple sans travaux de finition, une diminution de la matière première utilisée, un entreposage simplifié et des coûts de fabrication plus bas.

Claims (7)

Listel coupant amovible à insérer dans une rainure du plateau d'un massicot, caractérisé par un profilé extrudé en matière plastique, lequel présente une face supérieure plate, et, sur la face inférieure, au minimum un profilé moulé saillant pouvant être inséré dans un évidement d'un organe de retenue, évidement dont la forme est complémentaire de celle du profilé saillant, ce profilé se maintenant alors dans l'évidement par un mécanisme d'enclenchement.
2. Listel coupant selon la revendication 1, caractérisé en ce que l'organe de retenue est constitué par une tringle métallique pouvant être fixée dans la rainure du plateau.
3. Listel coupant selon la revendication 1 ou 2, caractérisé en ce que le profilé est constitué d'une matière plastique de haute résilience, par exemple en polypropylène ou en polyéthylène à haute densité moléculaire.
4. Listel coupant selon l'une des revendications 1 à 3, caractérisé en ce que le profilé en matière plastique présente une partie supérieure en forme de plaque d'une épaisseur d'environ 1 mm en vue de la pose sur des surfaces supérieures planes de l'organe de retenue.
5. Listel coupant selon la revendication 4, caractérisé en ce que le profilé moulé saillant est de forme tubulaire.
6. Listel coupant selon la revendication 5, caractérisé en ce que la profondeur du profilé saillant, mesurée à partir de la face inférieure de la partie supérieure en forme de plaque, est inférieure à celle de l'évidement de forme complémentaire dans l'organe de retenue.
7. Listel coupant selon l'une des revendications 1 à 3, caractérisé en ce que le profilé en matière plastique possède, à la face inférieure, deux profilés moulés saillants qui forment les limites d'une rainure en queue d'aronde ou d'une partie saillante en queue d'aronde.
