Definitions

  • the invention relates to a cutterhead for machines for cross-cutting of Material webs, in particular paper or board webs, with in circumferential recesses arranged the knife drum lying against a contact surface the circumferential recesses clamped and along the contact surface adjustable knives.
  • Such a knife drum is in German Utility Model 295 12 032 disclosed.
  • Machines of the type mentioned have two knife drums whose helically arranged knives in circulation in pairs in cutting engagement to cut the web with a paper cut. To be integrity the knives must slide past each other without play, which is achieved by at least one of two cooperating Knives is arranged adjustable relative to the counter knife.
  • the invention is based on the object, the clamping and adjusting so improve that economical operation by a mass-reduced knife is possible.
  • a knife trommel with the features of claim 1.
  • An optimal clamping of the blade can be achieved according to a preferred embodiment in that the terminal block contacted with its wedge surface opposite end in the peripheral recess on a substantially tangentenparallelen clamping and sliding surface with the cutterhead and aligned by substantially radially to the cutterhead aligned clamping bolt and transversely aligned pressure pin can be acted upon. In this way, there is a relatively long projecting end of the terminal block, which acts under the action of the clamping and actuating forces of clamping bolts and pressure pin on the wedge surface on the knife pushing and clamping.
  • a positive connection which is formed by an engaging in a groove of the knife, projecting from the wedge surface of the terminal block nose.
  • the positive connection can also be formed by a stop step of the terminal strip which acts on the knife rear side.
  • the knife can preferably also be designed as a disposable blade having a relatively thin wall thickness.
  • material and weight savings according to a further proposal characterized in that in conjunction with a plastic shaft (CFK shaft) formed cutter drum relevant for the knife holder and - adjustment clamping and guiding surfaces are provided in embedded in the cutterhead metal strips.
  • the advantage achieved by the invention is that through the stable, large-scale blade support and the indirect attack of the adjusting a extremely low-mass, relatively thin and thus also parallel to the support plane deformable, economical knife can be realized.
  • the cross-cutting device 1 shown in Figure 1 is not part of a further shown cutting machine for cutting sheets of paper, Cardboard or the like.
  • the device designed as a synchronous cross cutter has as knife carrier a lower cutterhead 2 and an upper cutterhead 3, each occupied by several relatively thin blades 4 and 6 respectively are, of which only one is shown on each cutterhead.
  • a moving in the conveying direction 7 paper web 8 advised during circulation the two knife drums 2 and 3 in the direction of arrow 9 and 11 respectively two knives 4 and 6 in cutting engagement.
  • the knives 4 and 6 extend perpendicular to the plane of the drawing or in the longitudinal direction the knife drums 2 and 3 slightly helical, the knife 4 lying in a circumferential recess or pocket 12 of the cutterhead 2 by means of a or more juxtaposed terminal strips 13 and clamping bolt 14 attached is.
  • the upper knife 6 is in a peripheral recess or pocket 16 of the cutterhead 3 also lying by means of one or more strung together Clamping strips 17 and clamping bolts 18 attached, with the knife 6 with his a broad side on a contact surface 19 of the cutterhead 3 is supported and with this forms a Gleit lake Unit. With its opposite side is the knife 6 in accordance with Figure 3 positive fit with the terminal block 17 via a into a groove 21 of the Knife engaging, projecting nose 22 on a parallel to the contact surface 19th extending wedge surface 23 in operative connection.
  • the clamping bolt 18 penetrate the terminal block 17 at the rear end in a relative to the bolt diameter enlarged opening 24, wherein the clamping bar 17 within the range of motion of the bolt bump 24 by engaging at its rear end pressure pin 26 along a substantially tangentenparallelen clamping and sliding surface 27 of the cutterhead. 3 can be adjusted with its inclined wedge surface 23 entraining the knife 6, which is advanced along its sliding guide on the contact surface 19 against the lower blade 4 and set helically over the length of its backlash. Trained as a relatively thin disposable knife diameter 6 is advanced by the rear pressurization of the terminal block 17 by overcoming the rear clamping force of the clamping bolt 18 caused elastic transverse deformation of the relatively long front end of the terminal block 17 along the contact surface 19 to the outside.
  • the cutterhead 203 formed as a plastic shaft (CFRP shaft). Only the at the Knife clamping and knife displacement heavily stressed elements, such as the Bearing surface 219 of the blade 206 and the sliding surface 227 for the rear end the terminal block 217 are as a separate, the pressure pin 226 receiving Metal parts inserted into the plastic shaft 203.
