Definitions

  • the invention relates to an arrangement of sanding sheets on documents which carry the abrasive on one side and are provided on the other side with a layer of pressure-sensitive adhesive, which is covered by a removable cover, in the form of a tape.
  • the invention also relates to a dispenser for receiving and dispensing such an arrangement of sanding sheets.
  • Both embodiments have the disadvantage in common that when individual grinding wheels are torn off at the wheel edge, a section of the web or tongue remains which protrudes from the wheel edge.
  • This board cannot only have a negative impact on the grinding pattern. Rather, it still exists the risk that the grinding wheels tear in the area of the board or members of the board, since these protrude from the device-side grinding sheet holder and therefore very easily get caught on unevenness of the workpiece or the like when working with the grinding device.
  • the grinding wheel belts are wound into rolls, which are preferably introduced into appropriately designed dispensers. - Due to this arrangement, the grinding wheels pulled off the roll are curved. This curvature considerably complicates the exact application of the grinding wheels to the device-side grinding wheel holder. This is because there is a risk that the wheel may not lie completely flat on the device-side sanding sheet holder and may even wrinkles. The curvature forced out of the grinding wheels also makes it difficult to detach the flexible, removable cover from the pressure-sensitive adhesive layer.
  • the pressure-sensitive adhesive layer is also not protected by means of a removable cover. While this reduces the cost of manufacture, however, the adhesive force of the pressure-sensitive adhesive layer can be Staubeinwir- kun g, which is not excluded if the packaging or the dispenser is already open, are so greatly reduced that the adhesion between the grinding wheel and the apparatus-side abrasive sheet receiving is so small that the respective grinding wheel quickly detaches from the device-side grinding wheel holder.
  • the known grinding wheel assemblies can only be produced with special punches due to the complicated design of the underlay, which is adapted to punching tools of the shape of the underlay to be punched out.
  • This object is achieved with an arrangement of abrasive belts of the presupposed type in that the abrasive sheets are combined to form a band by connecting strips connected to the covers, and the adjacent abrasive sheets lie flat on top of one another with folds of the free section of the connecting strip lying between two adjacent abrasive sheets come.
  • the sanding sheets are thus produced separately and only then combined into a band by the proposed application of the connecting strips.
  • the sanding sheets connected in this way to form a band are finally stacked flat on top of one another, folding the respective free section of the connecting strip lying between two adjacent sanding sheets.
  • the sanding sheets are packaged and stored in this arrangement.
  • the solution according to the invention has the advantage that the sanding sheets removed from the connecting strips have a completely smooth edge because there are no protrusions, as is the case with the known grinding wheels.
  • Another advantage of the arrangement according to the invention is that the sanding sheets are always flat. This means that the sanding sheets can be easily and precisely applied to the sanding sheet holder on the device. The always flat sanding sheets also make it easier to remove the flexible cover from the adhesive layer.
  • the sanding sheet arrangement according to the invention is simple and inexpensive to manufacture. The sanding sheets are manufactured individually with simple devices. With an equally simple additional device, the connecting strips are then only connected to the covers of the linearly arranged sanding sheets in order to combine them into a band.
  • the connecting strip provided according to the invention can consist of paper, film or a textile material.
  • the material only has to be sufficiently flexible so that it can be deformed and folded without the risk of tearing or permanent kinking.
  • the connecting strip is considerably narrower than the width of the connecting sanding sheets.
  • a connecting strip connects only two adjacent abrasive belts to one another.
  • it can also be expedient if a continuous connecting strip is used for the entire band.
  • the cover of the pressure-sensitive adhesive layer of the sanding sheets can be designed as usual. The side of the cover facing away from the pressure-sensitive adhesive layer only has to be such that the connecting strip can be well glued to the cover using conventional adhesives.
  • the sanding sheets are always flat in the arrangement according to the invention, this can also be used for abrasives of coarse grain, which is not possible in the known arrangements due to the rolling up of the sanding sheets on rollers.
  • the sanding sheets can be stacked on top of one another in two ways.
  • each abrasive sheet comes to rest with its cover on the abrasive side of the adjacent abrasive sheet in the belt. This results in a particularly simple way of removing the respective sanding sheet because the abrasive side of each sanding sheet is on top.
  • the length of the free, ie not connected to the covers, section of the connecting strip lying between two adjacent sanding sheets can correspond to the length of one sanding sheet. In this case, this section comes to lie between the adjacent grinding belts.
  • each abrasive sheet lies with its abrasive side against the abrasive side of one adjacent abrasive sheet and with the cover against the cover of the other adjacent abrasive sheet and the length of the free, lying between two adjacent abrasive sheets free section of the connecting strip corresponds to twice the thickness of the sanding sheet.
  • the arrangement according to the invention is suitable not only for round sanding sheets, but also for sanding sheets of any other shape.
  • a dispenser which has an edge in the region of its removal openings, over which the sanding sheet to be removed in each case with its cover can be pulled away from the sanding sheet while deflecting it, is particularly advantageously suitable for receiving and dispensing the arrangement of sanding sheets according to the invention. In this way, when the respective sanding sheet is simply pulled out by grasping it at the free end of the connecting strip, the cover is detached from the pressure-sensitive adhesive layer of this sanding sheet.
  • the dispenser advantageously also represents the packaging.
  • it preferably consists of cardboard.
  • the pull-off edge is expediently reinforced, e.g. by means of a second layer of cardboard or by means of an aluminum strip that is glued or riveted on.
  • a separate dispenser which, for example, consists of metal and is designed to hold several sanding sheet belts, e.g. with sanding sheets of different sizes or abrasives of different grain sizes.
  • the grinding sheets which are designed as circular grinding disks and are designated overall by 10 or 20, each consist of a base 11 or 21, on one side of which the abrasive 12 or 22 is applied and the other side of which is provided with a layer of pressure-sensitive adhesive which is covered by a cover 13 or 23 is protected.
  • the individual grinding wheels 10 and 20 are combined to form a band by connecting strips 14 and 24 connected to the covers 13 and 23, respectively.
  • each grinding wheel 10 comes to lie flat with the cover 13 on the abrasive side 12 of the grinding wheel 10 adjacent in the band and lying underneath.
  • the length of the free section of the connecting strip 14 lying between two adjacent grinding wheels 10 is adapted approximately to the diameter of a grinding wheel 10.
  • This free section of the respective connecting strip 14 comes to lie between the adjacent grinding wheels 10. Due to this arrangement, as indicated in FIG. 1, the grinding wheels 10 can be pulled off the stack by pulling on the free end of the connecting strip 14 of the uppermost grinding wheel 10 by unfolding the connecting strips 14.
  • each grinding wheel 20 lies flat with its abrasive side 22 against the abrasive side 22 of one adjacent grinding wheel 20 and with the cover 23 against the cover 23 of the other adjacent grinding wheel 20.
  • the length of the free section of the connecting strip 24 lying between two adjacent grinding wheels 20 corresponds approximately to twice the thickness of a grinding wheel 20.
  • Both embodiments have in common that a comparison Bonds g sstMake 14 and 24, only two adjacent grinding wheels 10 and 20 to each other.
  • This dispenser shows a dispenser from which the individual grinding wheels 20, e.g. 3 are arranged, can be removed.
  • This dispenser is labeled 40 in total. It consists of a housing, e.g. made of metal, which has a removal opening 41 on its upper side.
  • a plate 43 is arranged on a long side of the dispenser 40, which extends obliquely upwards and ends in an edge 42 which lies above the removal opening 41 of the dispenser 40.
  • the plate -43 continues from the edge 42 in the form of an upwardly open channel 44 in which two slots 45 are formed.
  • a box 50 in which a stack of grinding wheels 20 is mounted is inserted into the dispenser housing, which is designed to hold two boxes, each with a stack of sanding sheets.
  • the lid of the carton 50 is folded up and held in this position by a tab on the plate 43.
  • the top grinding wheel 20 is guided into the area of the edge 42.
  • the cover 23 is, for example, by pulling on the front strip-Verbindun s g a piece 24 in the front region of the grinding wheel 20 removed and inserted into the associated slot 45th If the front connecting strip 24 or the detached part of the cover 23 is pulled in this position, the cover 23 is completely detached from the grinding wheel 20 under consideration by pulling it out of the slot 45, so that this grinding wheel 20 can be removed from the belt.
  • the respective cover 23 is removed from the subsequent grinding wheels 20 simply by further pulling on the connecting strips or the covers.
