Definitions

  • the present invention relates to a method of cutting paper products in which the paper products are cut in at least one side in a cutting device.
  • Such a cutting method is basically known from the prior art and serves, for example, to trim the paper products coming from a printing press on, for example, three pages to the desired format.
  • the side trimming is carried out for example with rotary cutting knives, which are equipped with individual blades and perform the cut against a counter knife.
  • cutting methods are known in which two intermeshing rotary cutting knives are used to cut the paper products.
  • the solution of this object is achieved by the features of claim 1 and in particular by the fact that following the side trimming the previously trimmed side of the paper products for finishing the cut surface is ground.
  • a grinding process in which the previously trimmed side of the paper products is ground only so far until any existing cutting marks are removed, for example by about 1/10 mm.
  • the cutting method according to the invention also makes it possible to cut very thick paper products, such as telephone directories or the like, to a desired size with rotary cutting knives, the products resulting from the method having an exceptionally uniform cut surface which is free of any cutting marks.
  • the inventive method is suitable for any type of paper products, such as magazines, stacks of magazines, catalogs, directories or even compressed or bundled cut sheets.
  • the paper products are held in a compressed state from the beginning of the cutting until the completion of the grinding, that is, the paper products are continuously compressed during cutting and grinding at least on the side where they have previously been cut.
  • the compression can be done in an advantageous manner with the aid of Pressing tapes are already present on the cutting device.
  • the grinding of the product sides in the pressed state results in an extraordinarily high quality of the grinding surface, whereby the products can not reorient themselves between cutting and grinding.
  • the paper products can be conveyed during grinding. This results in a relative movement between the product to be ground and the grinding device used during the grinding process, which increases the uniformity of the cut but also the processing speed. This can also be achieved by moving the cutting and grinding devices relative to the product.
  • the paper products are ground with a grinding wheel which is oriented slightly obliquely to the previously cut side of the paper product.
  • a grinding wheel which is oriented slightly obliquely to the previously cut side of the paper product.
  • this relates to a grinding device, comprising a conveyor with the paper products can be transported along a conveying path, wherein in the region of the conveying path a pressing device is provided with which the subsidized Paper products are compressed during transport on at least one side.
  • a grinding device is provided in the region of the pressing device with which the paper products are ground in the area of the compressed side.
  • the grinding device may have a grinding wheel, which is oriented slightly obliquely to the conveyor line, so that it is ensured that the paper products can move safely into the grinding device.
  • the grinding device has a grinding wheel, which can be adjusted in the direction of the paper product to be ground, for example by means of a spring, a motor, a setting cylinder or the like. This ensures that there is no jamming when the paper product enters the grinding device. At the same time, the depth of the cut can be influenced by the contact pressure and the contact time.
  • the grinding device has at least two grinding wheels, which are mounted on a changing device.
  • the changing device may comprise a rotatable support, on which the at least two grinding wheels are mounted, so that by turning the carrier one of the grinding wheels can be brought into their working position and the other grinding wheel can be replaced and / or cleaned.
  • a cutting device is provided in the conveying direction in front of the grinding device, with which the paper products are cut in the region of the compressed side.
  • the grinding device can be used simultaneously for performing the edge trimming.
  • the grinding device has a protective housing, which prevents the spread of grinding dust.
  • the protective housing can in this case be provided with a dust extraction.
  • this relates to a grinding tool for carrying out the method according to the invention, wherein the grinding tool has a grinding plate on which a perforated grinding wheel is fixed by means of a clamping ring, wherein in the grinding plate a plurality of elongated channels are provided, through which a Extraction of sanding dust can be done.
  • Such a grinding tool is particularly well suited for the grinding of previously trimmed paper products, since the grinding wheel is easily interchangeable with the aid of the clamping ring. Furthermore, basically known holes are provided in the grinding wheel, so that suction can take place through the grinding wheel. Due to the elongated channels in the sanding pad, a large-area suction of the sanding dust is possible, so that the spread of dust is minimized overall.
  • the channels may be curved in plan view and extend from a radially inner end to a radially outer end.
  • the rotation of the grinding wheel can advantageously also be used to convey the resulting grinding dust within the elongated curved channels and depending on the direction of rotation to the radially inner end or to the radially outer end of the channels.
  • Fig. 1 shows a section through a grinding device having a conveyor in the form of a pair of belts 10, 11, which is driven by a drive device, not shown and between the paper products P, such as directories or the like can be transported along a conveyor line.
  • a respective pinch roller 12 and 14 is provided below the lower conveyor belt 10 and above the upper conveyor belt 11, which is pressed by means not shown in the direction of the paper product P.
  • the two pressure rollers 12 and 14 form a pressing device with which one side of the paper product P can be compressed during transport along the conveying path.
  • FIG. 1 shows a grinding device 20, which is provided in the region of the pressing device 12, 14 and with which the paper products P can be ground in the area of the compressed product side.
  • the grinding device 20 has a grinding wheel 22 shown in dashed lines in FIG. 1, which is clamped by means of a clamping ring 24 on a grinding plate 26 which is screwed by means of screws 23 to a rotatable shaft 28 via a motor, not shown.
  • the shaft 28 is mounted on a base body 30 which is movable by means of an actuator 32 on a carriage 34 so that the grinding wheel 22 can be made in the direction of the paper product P.
  • a spindle 33 is rotated, which in turn moves the base body 30 in the vertical direction in Fig. 1 to the right or left.
  • a control is provided, which always sets the grinding wheel 22 by a distance of about 1/10 mm in the direction of the paper product P, if this has passed the outer periphery of the grinding wheel 22 and is transported past the grinding wheel. Subsequently, the carriage 34 can be moved back again.
  • a total of twelve elongated channels 27 are provided in the sanding plate 26 in the illustrated embodiment, which are each open to the front and back of the sanding pad 26 and through An extraction of sanding dust can take place.
  • the channels 27 are curved in plan view and extend from a radially inner end A to a radially outer end B.
  • the sanding pad 26 is connected by screws 25, which clamp the clamping ring, with an intermediate ring 29, in which an annular suction channel 40 is provided in a connecting channel 42nd for a suction opens.
  • the intermediate ring seals against housing-fixed components 36 and 38 via a seal, not shown, which is received in an annular groove 44.
  • the grinding wheel 22 Since the grinding wheel 22 is provided with holes, the paper dust generated during grinding can be sucked through the holes of the grinding wheel.
  • 42 negative pressure is applied to the connecting channel, so that the grinding dust passes through the holes of the grinding wheel 22 first in the elongated channels 27 of the grinding plate 26 and from there into the annular suction channel 40 of the intermediate ring 29, before being sucked into the connecting channel 42. Since the grinding wheel 22 and the sanding pad 26 rotate in the counterclockwise direction in FIG. 2, this rotational movement assists in transporting the paper dust within the channels 27 in the direction of the outer end B. This contributes to a uniform removal of the resulting sanding dust can.
  • the described grinding device may be provided in a protective housing, which additionally prevents spreading of grinding dust.
  • the grinding device according to the invention is preferably integrated in a rotary cutting machine, as for example in the German patent application 10 2005 001 471 of January 12, 2005.
  • the disclosure of this patent application becomes explicit incorporated by reference into the content of the present application.
  • the individual paper products are trimmed on at least one side in a cutting device, as described, for example, in the preceding paragraph German patent application 10 2005 001 471 is disclosed.
  • the trimmed side remains held within the pressing device and the paper product is guided past the grinding device 20 with the aid of the conveyor belts 10, 11, so that following the side trimming, the previously trimmed side can be ground to refine the cutting surface.
  • the servo motor 32 is driven so that the grinding wheel 22 is made short to the passing paper product P.
  • the paper product P is thus held during grinding both in a compressed state and conveyed during grinding in the conveying direction.
  • suction of the grinding dust through the channels 27, 40 and 42 described above takes place.
