Definitions

  • the invention relates to a slitter-winder with at least one longitudinal cutting device for cutting a moving material web, in particular a paper or board web having a pair of knives comprising a knife supporting the material web during cutting and a knife dipping into the material web, both knives being separate or a common carriage are arranged, which are mounted on a respective transversely extending to the direction of the material web knife cross member preferably adjustable and each having a knife holder for supporting the associated knife.
  • Such a slitter is known for example from the publication "BiWind TM Winding Systems - Winders for Total Roll Structure Control” Beloit Corporation.
  • the illustrated unit has at least one longitudinal cutting device designated as “AUTOTRIM TM SLITTER” and optionally at least one device designated as “PRE-TRIM SLITTER” for the exclusive pre-trimming of the machine-width material web.
  • This device is occasionally necessary because the actual edge strips must not exceed a certain width, for example in the size of 150 mm, because they are no longer manageable otherwise. If the edge strips threaten to become too wide, then the material web must be "trimmed" beforehand.
  • the known and several slitting machines having slitting machines produce individual narrower bobbins from a wide web of material or individual bows by additional cross-cutting.
  • the pairs of circular knives can be positioned transversely to the running direction of the web.
  • the pairs of knives in an embodiment of circular knives each consist of a the knife during the cutting supporting pot knife and a dipping into the track tip knife whose cutting edges must be positioned exactly to each other in the desired cutting position.
  • the pot knife used as a lower blade is driven, while the tip blade is freely rotatably mounted as a top blade. This is for example in the German patent DE 34 19 843 C2 described.
  • edge strips The drive or driver side outermost pair of knives used to produce so-called edge strips.
  • the two edge strips are usually fed to a reject pulper, where they are suspended with the addition of water and returned to the paper or board machine together with the stock flow from stock preparation. Although these edge strips are rejects, there is no material loss.
  • the further inside pairs of knives serve to divide the machine-wide material web into individual tracks. For example, if you want to produce four finished rolls, you will need three inside pairs of knives.
  • the invention is therefore the object of developing a reel cutting machine of the type mentioned in such a way that it has improved reliability in terms of RandstMailab Entryen at all possible web widths. Furthermore, it should be inexpensive to purchase and in operation.
  • This object is achieved in that two each having a knife pair having edge knife stations are provided for generating a respective edge strip, which are arranged opposite to the running direction of the material web in the respective edge region of the material web.
  • the two edge strips are produced both upstream and independently of the possibly varying in number longitudinal slitting devices.
  • This allows a great deal of flexibility in terms of the use of slitting devices, since non-operational but existing slitter devices are simple can be parked in at least one side arranged "knife station".
  • the two edge knife stations can be positioned and operated completely independently of the longitudinal cutting devices, thus resulting in improved functional reliability with regard to edge strip removal in all possible web widths.
  • Also can be due to the geometric arrangement of the edge knife stations together with associated drives with respect to the downstream pairs of blades together with associated drives produce arbitrarily narrow marginal roles.
  • the two knives of the knife pairs of the two edge knife stations are each arranged on a carriage, which are preferably adjustably mounted on each one extending transversely to the direction of the material web knife crossbar and each a knife holder for supporting the associated knife exhibit.
  • a carriage which are preferably adjustably mounted on each one extending transversely to the direction of the material web knife crossbar and each a knife holder for supporting the associated knife exhibit.
  • this makes possible a simple and quick adaptability of the two edge knife stations to changed properties of the edge strips.
  • Such a property may be, for example, the marginal strip width, which usually takes on a value in the range of 10 to 200 mm, especially 20 to 70 mm.
  • At least one edge-knife station mounted on a slide by means of a knife holder must be adjusted transversely to the direction of travel of the material web in order to maintain a necessary or desired edge-strip width.
  • At least one pair of knives of the two edge knife stations is adjustable by means of at least one adjusting device preferably also during operation of the slitter along the transversely extending to the direction of the material web knife crossmember.
  • a preferred practical embodiment provides that at least one of the two knife holders of a pair of knives is adjustable. This allows easy adjustment or readjustment of the knife pair, in order to be able to vary, for example, the immersion depth of the two knives with changed production parameters.
  • the adjustable knife holder of the edge knife stations are hereby preferably arranged mutually of the adjustable knife holder of the at least one longitudinal cutting device, so that mutually takes place employment in the material web.
  • At least one marginal knife station in the edge region of the material web is additionally assigned at least one longitudinal cutting device having a pair of knives for producing a preliminary trimming.
  • the edge strip width can be easily kept below a maximum allowable value.
  • the respective edge knife station is preferably associated with at least one removal device for the cut edge strip.
  • the discharge device may comprise, for example, at least one mechanical guide plate, one or a discharge device acted upon by at least one vacuum.
  • At least one guide roller is preferably arranged between the two edge-knife stations and the at least one longitudinal cutting device the possibility of influencing for the purpose of ensuring an integrity run of the web creates.
  • a knife train yard is assigned to at least one pair of knives of a longitudinal cutting device, so that it can be safely parked in the event of non-operation and not disturbing.

  • the bottom blade used is 5 pot knives
  • the top blade 6 is disk-shaped pointed knives, as used, for example, in the already mentioned German patent DE 34 19 843 C2 are described.
  • the two knives 5, 6 are arranged on a respective carriage 7, 8, which in each case extending transversely to the running direction L (arrow) of the material web 3 Knife traverse 9, 10 are adjustably mounted and each having a knife holder 11, 12 for supporting the associated blade 5, 6 have.
  • Each knife 5, 6 can be positioned transversely to the direction of travel L (arrow) of the material web 3 to be divided in order to set the required format width.
  • each upper blade 6 in the direction of its axis of rotation against the associated lower blade 5 can be adjusted so that the two cutting edges can be aligned exactly relative to each other.
  • the blades 5, 6 may of course be mounted on a common carriage.
  • two edge measuring stations 14 each having a pair of knives 15 are provided in the respective edge region 13.1, 13.2 of the material web 3 for producing a respective edge strip 16.1, 16.2.
