Definitions

  • the invention relates to a knife drum for machines for cross cutting Material webs, in particular paper or cardboard webs, with circumferential recesses the knife drum arranged horizontally, against a contact surface the circumferential recesses can be 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, the helically arranged knives cut in pairs when circulating to cut the web with a paper cut. To be flawless to be able to cut, the knives must slide past each other without play, what is achieved by the at least one of two interacting Knives is arranged adjustable relative to the counter knife.
  • the invention is based, so the clamping and adjusting means improve that economical operation through a reduced-mass knife is possible.
  • the one with a broad side with the contact surface forming a sliding surface guide on the opposite broad side is positively or frictionally connected with a parallel to the contact surface wedge surface of a lockable by clamping bolts and displaceable by pressure bolts terminal block in operative connection.
  • An optimal clamping of the knife can be achieved according to a preferred embodiment in that the clamping strip with its end opposite the wedge surface in the circumferential recess makes contact with the knife drum on a substantially tangent parallel clamping and sliding surface and by means of clamping bolts aligned essentially radially to the knife drum and transversely aligned push pin can be acted upon.
  • the knife can preferably also be designed as a disposable knife having a relatively thin wall thickness.
  • material and weight savings are possible according to a further proposal in that the clamping and guide surfaces relevant for the knife holder and adjustment are provided on metal strips embedded in the knife drum in conjunction with a knife drum designed as a plastic shaft (CFRP shaft).
  • the advantage achieved with the invention is that the stable, large knife support and the indirect attack of the adjusting means extremely low mass, relatively thin and therefore also parallel to the support plane deformable, economically usable knife is realizable.
  • the cross cutting device 1 shown in Figure 1 is part of a format cutter, not shown, for cutting sheets of paper, cardboard or the like.
  • the device designed as a synchronous cross cutter has a lower knife drum 2 and an upper knife drum 3 as knife carriers, each of which is equipped with a number of relatively thin knives 4 and 6, of which only one is shown on each knife drum.
  • a paper web 8 moving in the conveying direction 7 two knives 4 and 6 each come into cutting engagement when the two knife drums 2 and 3 rotate in the direction of the arrows 9 and 11, respectively.
  • the knives 4 and 6 extend perpendicularly to the plane of drawing or in the longitudinal direction of the knife drums 2 and 3, respectively, in a slightly helical manner, the knife 4 being fastened lying in a circumferential recess or pocket 12 of the knife drum 2 by means of one or more clamping strips 13 and clamping bolts 14 arranged in a row .
  • the upper knife 6 is also fastened lying in a circumferential recess or pocket 16 of the knife drum 3 by means of one or more clamping strips 17 and clamping bolts 18 lined up with one another, the knife 6 being supported with its one broad side on a contact surface 19 of the knife drum 3 and with it one Sliding surface guidance forms. With its counter-wide side, the knife 6 is positively connected to the terminal strip 17 according to FIG.
  • the clamping bolts 18 penetrate the terminal strip 17 at the rear end in an opening 24 which is enlarged relative to the bolt diameter, the terminal strip 17 within the scope of movement of the bolt opening 24 by means of pressure bolts 26 acting on its rear end along an essentially tangent-parallel clamping and sliding surface 27 of the knife drum 3 is adjustable with its inclined wedge surface 23 taking the knife 6, which is advanced along its sliding guide on the contact surface 19 against the lower knife 4 and is set helically free of play over its length.
  • the knife 6, which is designed as a relatively thin disposable knife, is advanced to the outside by the elastic transverse deformation of the relatively long front end of the clamping bar 17 along the contact surface 19, which is caused by the rear pressurization of the clamping bar 17 while overcoming the rear tensioning force of the clamping bar 18.
  • the knife drum 203 designed as a plastic shaft (CFRP shaft). Only the one at Knife clamping and shifting elements, such as the Contact surface 219 of the knife 206 and the sliding surface 227 for the rear end the terminal block 217 are separate, also receiving the pressure bolts 226 Metal parts inserted into the plastic shaft 203.
