Definitions

  • the present invention relates to abrasive belts for sanding-smoothing machines, including a horizontal operative roller, onto which an abrasive paper belt forming a sleeve is mounted; the belt is aimed at eliminating defects, such as long undulations, present in wooden floors.
  • Some sanding-smoothing machines include one operative roller while other machines include two operative rollers.
  • the first type of machines includes one tensing roller and one operative roller, e.g. horizontal; a belt of abrasive paper is mounted around both rollers.
  • the second type of machines include two operative rollers, which have horizontal axes too; an abrasive paper is mounted on each of these horizontal operative rollers.
  • the belt of abrasive paper forms a sleeve, whose section allows it to be put on the related roller/s, so as to tightly surround it/them.
  • the above mentioned machines are used for roughing-out and/or smoothing wooden floors.
  • the handle of the machine is slightly pressed in the direction of its movement; the pressure must be stronger in case roughing-out is to be performed, and slighter in case of finishing or smoothing.
  • This procedure features some disadvantages deriving from the too rigid structure of the sleeves of abrasive paper.
  • the sleeve does not adhere to the operative roller tightly enough and consequently, during operation, the operative roller speed and the machine movement speed make the sleeve slide on the operative roller, since the operative roller and the sleeve touch each other with smooth surfaces.
  • the traditional sleeve presents also other disadvantages; during operation, the sleeve can rough out and/or smooth a portion of the floor equal to the length of the operative roller, on which it is mounted.
  • the lines can be removed only by another run of the machine, which results in waste of time, bigger use of abrasive belt and further reduction of the floor thickness.
  • the rigidity prevents a perfect smoothing of the surface, i.e. does not effectively eliminate or level the considerable undulations deriving from an imperfect floor assembly, since the contact between the operative roller and the floor is not always ensured.
  • the main object of the present invention is to reduce the rigidity of the sleeve/operative roller assembly, so as to make the latter auto-modeling in order to avoid the above described disadvantages.
  • Another object of the present invention is to increase the working area of sleeves of abrasive belt, mounted on each operative roller.
  • the reference numeral 2 indicates a machine for sanding-smoothing wooden floors P, including operative rollers
  • the reference numeral 3 indicates a machine including only one operative roller.
  • the machine 2 with two operative rollers 6, 7, includes has abrasive belt sleeves 8, 9 mounted on the rollers, while the machine 3, equipped with one tensing roller 5 and one operative roller 50, includes has abrasive belt sleeve 55, whose dimensions are bigger with respect to the belts of the first machine, since it is trained around both rollers 5, 50 ( Figure 5).
  • the external part of the sleeves is made of abrasive paper, whose grain is suitable for roughing-out and smoothing.
  • the inner part of the abrasive paper features a layer of soft material M, e.g. foam rubber, which is to be set in adherence onto each of the operative rollers 6, 7, 50.
  • a layer of soft material M e.g. foam rubber
  • the layer of the material M is applied to the inner surface of the paper by suitable adhesive means.
  • foam rubber can be substituted by other materials of identical characteristics, such as fabric, cloth, natural or synthetic rubber, polyurethane foams or similar, or any kind of flexible material.
  • the so-obtained sleeve is inflated with a selected pressure, so as to obtain a particularly soft layer.
  • the layer of material M allows the sleeves to adhere perfectly to the surface of each operative roller, on which they are mounted, thus increasing the friction between the contact surfaces, and subsequently, the driving power the operative roller can exert on the sleeve.
  • the pressure is uniformed in the whole contact area, so as to assure that the operative roller touches the floor along its whole length.
  • the above described sleeves can be used for sanding-smoothing machines with either one working sleeve or two working sleeves; only the sleeves dimension change, so that they can adhere perfectly to the corresponding operative rollers.
