Definitions

  • the invention relates to a device for miter-compatible cutting of abutting edges on rubber plates or plates made of a similar material, with a knife inclined transversely to the cutting direction, which is mounted on a base frame provided with a support plane for the rubber plate and two guide rails slidably in the cutting direction , being a first

  • Such rod guides which have one or two guide rods, have long been known per se. With this type of guidance, the sled body cannot be removed, but instead in the case of particularly thick rubber plates, which oppose the knife with a very high cutting pressure, the guidance of the knife is facilitated, since the force exerted on the knife by the operator to move the carriage cannot cause the carriage body to be inadvertently lifted off.
  • Miter bodies which differ in the height and inclination of the contact surface for the knife, the device can be converted to cut different miter angles on the abutting edges of the rubber plates.

Abstract

Un dispositif de découpage de plaques en caoutchouc ou en un matériau similaire, de sorte que leurs bords forment un assemblage à onglet, comprend un couteau (5) incliné orienté transversalement au sens de découpage et monté de manière coulissante dans le sens de découpage (S) sur un cadre de base (7) pourvu d'un plan de support (E) de la plaque en caoutchouc (4) et de deux rails de guidage (10, 11). Un premier rail de guidage (10) est agencé au-dessous du plan de support (E) afin de guider l'extrémité libre (13) de la lame (6) et un deuxième rail de guidage (11) est agencé avec un écartement au-dessus du plan de support (E) afin de guider le couteau habituel (5). Afin de pouvoir obtenir des rebords découpés de manière plus simple et moins polluante, le couteau du dispositif comprend une lame chauffable (6) et deux barres de serrage de la plaque en caoutchouc (4) qui s'étendent dans le sens de découpage (S) et sont agencées à proximité immédiate de la lame (6). La première barre de serrage (15) s'appuie avec un bord longitudinal (35) situé sur le plan de support (E) contre le côté inférieur de la lame (6) et la deuxième barre de serrage (14), qui est située avec un écartement au-dessus du plan de support (E), s'appuie avec un bord longitudinal (36) contre le côté supérieur de la lame (6).
