- the pad which is of lofty material, allows some adjustment of the abrasive flaps with respect to possible uneven floor parts.
- the abrasive flaps are generally parallel to the surface of the pad and are connected thereto by means of hook shaped protrusions. It is a drawback of this arrangement that the maximum rotation speed of the abrasive article is limited.

It is also possible to arrange the flaps in a series which is continuous in circumferential direction) (360°). One or more series may be arranged in concentric fashion. In radial direction, the flaps may exactly cover each other. However, it is also possible to make the flaps overlap each other only partly in radial direction. Thus, the flaps may be offset laterally with respect to each other, in such a way that a series is obtained which is wider than the width of the individual flaps.
- a circular ring shape of the series of abrasive flaps is more preferred as thereby the regular treatment of the floor is increased.
- the support layer may be ring shaped accordingly.

Furthermore, it is possible to have flaps which are fit for increasing the gloss of a floor, e.g. of a marble or granite floor and the like.
- the pad may also be carried out in different ways; preferably, the pad has a lofty character and comprises a nonwoven three dimensional web of fibers which are bonded to one another at points of mutual contact.
- the support layer may comprise a textile layer which is adhered to a resin layer through a very thin glue layer.

The flaps cover the pad and overlap each other in the circumferential direction of the pad (2). Also, the flaps (6) are each attached to a support layer (5) interposed between the pad (2) and the flaps (6).
Description
- The invention is related to a treatment article for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum, concrete, terrazzo and the like, comprising a pad having major surfaces facing away from each other and a plurality of abrasive flaps on one of said major surfaces of the pad, which flaps at least partly cover the pad, a rotation axis being defined perpendicular with respect to the major surfaces.
- A treatment article of this kind is disclosed in U.S. Pat. No. 6,234,886. Said prior art treatment article has a plurality of abrasive sheets. Said abrasive sheets are spaced from each other and are arranged according to specific patterns on the surface of the pad. The abrasive article may be used for sanding operations, for buffing, polishing and the like depending on the abrasive character thereof.
- The abrasive article can be applied to a floor treating machine which has a frame carrying a drive motor and one or more drive heads. The abrasive article is mounted onto a drive head; by controlling the drive motor the drive head is set in rotation. By means of a handle which is connected to the frame, the operator is able to direct the floor treating machine over a floor so as to carry out the treatment thereof. The pad, which is of lofty material, allows some adjustment of the abrasive flaps with respect to possible uneven floor parts.
- The abrasive flaps are generally parallel to the surface of the pad and are connected thereto by means of hook shaped protrusions. It is a drawback of this arrangement that the maximum rotation speed of the abrasive article is limited. Relatively high rotation speeds would lead to a considerable temperature increase having regard to the fact that the full surface of the abrasive flaps is pressed into contact with the floor. Furthermore, the abrasive flaps may become disengaged from the pad. Thus, the productivity of these prior art abrasive articles is necessarily relatively low.
- The object of the invention is to provide a treatment article by means of which the treatment of an object, in particular of a floor, can be carried out more efficiently and at higher speeds than possible with the prior art treatment articles. This object is achieved in that the flaps overlap each other in at least the circumferential direction of the pad and are each attached to a support layer interposed between the pad and the flaps.
- According to the invention, the treatment article does have flaps for carrying out a certain treatment of e.g. a floor, supported by the pad. Thus, the treatment article is able to adjust to any uneven aspect of the floor in question. The flaps have a somewhat slanted position with respect to the floor surface as a result of the fact that said flaps overlap each other. Each flap at one end is positioned underneath a preceding flap and at the opposite end is positioned above a following flap, when seen in circumferential direction (roof tile fashion). Thereby, the area of contact between the flaps and the floor is reduced. As a consequence, the heat generated during rotation of the treatment article over the floor is reduced. Thus, it is made possible to rotate the treatment article at a relatively high speed. Moreover, the flaps are firmly held to support layer on the pad in a mutually overlapping fashion, which further increases the resistance against disintegrating. As a result of the higher speeds, the productivity of the treatment article is increased.
- The flaps may be arranged according to a series, preferably according to a series which is at least partly circular and concentric with respect to the rotation axis. Other arrangements are possible as well, for instance in the form of a series of flaps which is spiral shaped with respect to the rotation axis. According to a further embodiment, the flaps may be arranged according to an intermittent series comprising groups of flaps which are at a distance from each other. It is also possible to arrange the flaps in a series which is continuous in circumferential direction) (360°). One or more series may be arranged in concentric fashion. In radial direction, the flaps may exactly cover each other. However, it is also possible to make the flaps overlap each other only partly in radial direction. Thus, the flaps may be offset laterally with respect to each other, in such a way that a series is obtained which is wider than the width of the individual flaps.
- Furthermore, a circular ring shape of the series of abrasive flaps is more preferred as thereby the regular treatment of the floor is increased. Furthermore, the support layer may be ring shaped accordingly. Most preferably, the series of abrasive flaps and/or the support layer are/is located adjacent or bordering the outer circumference of the pad. The flaps may also be arranged in accordance with two or more concentric ring shapes.
- The major surface central portion of the pad lofty material onto which the flaps are connected, may have a central portion which is free from flaps. Also the support layer may have a central portion which is free from flaps. The flaps are thus concentrated at the outer parts of the pad and/or of the support layer which have the highest circumferential speeds, which is favorable for the treatment action.
- The flaps may be mounted in several ways onto the support layer and the pad. For instance the flaps may be clamped onto the pad, or be connected thereto by means of hooks and the like. Preferably however, the support layer is at least partly covered with a glue layer, one edge of each flap being embedded in said glue layer.
- The flaps may comprise abrasive particles, such as particles of diamond, cubic boron nitride, aluminium oxide, silicon carbide, zirconium or any other abrasive substance or polishing compound. However, the flaps need not always have an abrasive character. It is also possible that the flaps have a treatment surface which is fit for daily or weekly maintenance of a floor, or for cleaning the floor. Furthermore, it is possible to have flaps which are fit for increasing the gloss of a floor, e.g. of a marble or granite floor and the like.
- The pad may also be carried out in different ways; preferably, the pad has a lofty character and comprises a nonwoven three dimensional web of fibers which are bonded to one another at points of mutual contact. The support layer may comprise a textile layer which is adhered to a resin layer through a very thin glue layer. Such support layer is relatively stiff in bending and may yet flex somewhat under the influence of the floor irregularities encountered when operating the floor machine onto which the abrasive article is mounted. The textile material may be located on the side of the support layer which faces the flaps. As mentioned, the support layer is at least partly covered with a glue layer. One edge of each flap is embedded in said glue layer and is adhered to the textile layer of the support layer by said glue layer. The somewhat rough character of the textile material promotes a reliable bond between the support layer and the flaps. In particular, the tensile stiffness of the support layer may be higher than the tensile stiffness of the lofty pad. The diameter of the treatment article may be selected in accordance with the envisaged application.
- The invention is furthermore related to a floor treatment machine comprising a frame, at least on rotary drive head, drive means for driving the rotary drive head in rotation about the axis thereof, handling means for controlling and steering the machine over a floor to be treated as well as a treatment article according to any of the preceding claims for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum, concrete, terrazzo and the like, comprising a pad having major surfaces facing away from each other and a plurality of flaps on one of said major surfaces of the pad and which at least partly cover the pad.
- Such a floor treatment machine is disclosed in U.S. Pat. No. 6,234,886 as well. According to the invention, this floor treatment machine is characterized in that the flaps overlap each other in the circumferential direction of the pad and are each attached to a support layer interposed between the pad and the members and in that the other major surface of the pad is supported against the rotary drive head.
- As mentioned before, the floor treatment machine may be used more efficiently and at relatively high speeds. Thus, it is preferred that the treatment article, which is in contact with a floor, and the associated rotary drive head are rotated at a rotational speed of at least 175 rpm, preferably at least 800 rpm. Preferably, the rotational speed is in the range of 175-2000 rpm.
- The pad may be carried out in different ways, and may e.g. comprise a lofty material of entangled fibers which enclose open pores, or of an expanded PVC material and the like.
- The floor treatment machine may be carried out with a single treatment head. Such type of floor treatment machine may be used for grinding or polishing purposes. Also the floor treatment machine may be carried out as a so-called burnisher which usually are operated at relatively high speeds for e.g. buffing, cleaning or polishing. Furthermore, the floor treatment machine may be carried out as a cleaning machine or so-called auto-scrubber or scrubber dryer. Also, the treatment article may be used on a single head cleaning machine or so-called “swing machine”. The treatment article may be used under dry conditions, or in the presence of liquids which act as e.g. a coolant and/or as dust control.
- The invention will be described further with reference to the drawings.

flaps 6 are arranged according to a ring shapedseries 7 which is concentric to the mountinghole 18 in thepad 2 and which generally covers the ring shapedsupport layer 5. By means of athick glue layer 10, one of theedges 8 of eachflap 6 is embedded in aglue layer 10; thereby the flaps are firmly adhered to thetextile layer 16 of thesupport layer 5. Thetextile layer 16 which is on the lower surface of the resin layer and which has a certain roughness, promotes the formation of a strong and reliable bond with respect to theglue layer 10 and theflaps 6. - Adjacent flaps are arranged in the way of overlapping roof tiles, in such a way that the opposite end 9 of the flaps is free. Each flap is partly covered by a preceding
flap 6′, seen in the direction of movement of theseries 7 offlaps 6 as depicted by the arrows inFIGS. 1 and 2 . Saidflap 6 in turn partly covers a followingflap 6″, and so on. Eachflap 6 has asurface 15 facing away from thepad 2 which is provided with e.g. abrasive particles. Thesurface 15 of eachflap 6 is in contact with the floor to be treated, in so far as thesurface 15 extends beyond the precedingflap 6′ as shown inFIG. 2 . - The
major surface 3 of thepad 2 is covered only over a ring shaped part at the outer circumference; thecentral part 11 of the major surface is completely uncovered. The uncovered surface of the pad may be smaller in case a second ring shaped series (not shown) of flaps is arranged inside the outer series. - The embodiment of
FIG. 4 shows an alternative arrangement of theflaps 6 according to several spiral shapedseries 7′. These series are regularly distributed in the circumferential direction of thepad 2, in such a way that the treatment article is well balanced. - The alternative embodiment of
FIG. 5 shows flaps (6) which are arranged according to anintermittent series 7″, 7′″'. These series comprisegroups 21 of flaps which are formed according to a part of a circle which is concentric with respect to therotation axis 19. In the embodiment shown, the groups are equidistant to the rotation axis and are at a distance from each other in circumferential direction. Here as well, the distribution of the groups of flaps is such that the treatment article is well balanced. - Although in the embodiments shown subsequent flaps cover each other fully in radial direction, it is also possible to make subsequent pads overlap each other with some offset in radial direction.
- For the purpose of mounting the
treatment article 1 onto the treating machine, theupper surface 4 of the pad is provided with areleasable loop layer 18. Conversely, thedrive head 12 is equipped with a hook layer which connects to the loop layer. It is also possible to apply the loop layer on the drive head, and the hook layer on the pad. By means of these hook and loop fasteners, the oppositemajor surface 4 of thepad 2 is connected to the lower surface of thedrive head 12 of afloor treating machine 13 as shown inFIG. 6 . Theseries 7 offlaps 6 is resting on the floor surface to be treated. Once the operator sets thedrive head 12 with thetreatment article 1 in rotary motion, thefloor treatment machine 13 is controlled by means of thehandle 14 over the floor so as to obtain the required treatment thereof. -
