Abstract
Description
- The invention relates to the field of winding rollers for flat strip material in towel dispensers.
- A typical towel dispenser typically comprises two rollers. A first roller on which a roll of clean cloth is provided and a second roller for winding up the cloth that has been used, the so-called winding roller. When all the clean cloth has been used, the first roller will be empty and a roll of used cloth will be winded on the winding roller. After removal of the winding roller, the used cloth will be washed and reused.
- When a new roll of clean cloth is provided in the towel dispenser, the end of the clean cloth is attached to the winding roller. This is usually done by clamping the end of the clean cloth into a groove in the winding roller. Publication
EP1176898 shows a system wherein the cloth is clamped into a groove in the winding roller by means of a pivoting rod. A disadvantage of clamping the cloth to the winding roller is that it makes the removal of the winding roller from the roll of used cloth more difficult. - It is an object of the invention to provide a winding roller that may be easily removed from the roll of used cloth.
- According to one aspect, the invention provides a replaceable winding roller for flat strip material in a towel dispenser. The roller comprises a substantially cylindrical roll, an outer surface of the roll forming a winding surface for winding the flat strip material, the roll comprising a groove axially extending from one end part of the roll to another end part of the roll. The groove is open on the one end part. The roller further comprises a freestanding pin being connected to the another end part of the roll, forming a gap between the groove and the pin into which the strip material may be slid. The freestanding pin is positioned in the groove below the winding surface and the gap distance between the groove and the pin is at least the width of the flat strip material in an uncompressed state.

Figure 1 : Schematic view of a replaceable winding roller according to the present invention. -
Figure 2 : Perspective view of an exemplary embodiment of a replaceable winding roller according to the present invention. -
FIG. 1A shows a perspective view of areplaceable winding roller 1 for flat strip material in a towel dispenser according to the present invention. The directions of two cross-sections of the roller A - A' and B - B' as shown inFIGS. 1B and 1C respectively, are indicated. -
FIG. 1B shows a schematic view of cross-section A - A' of thewinding roller 1 as indicated inFIG. 1A . Thewinding roller 1 comprises a substantiallycylindrical roll 2, an outer surface 3 of the roll forming awinding surface 4 for winding the flat strip material. The outer surface 3 of the roll preferably is a smooth surface to reduce frictional forces between the roller and the cloth while removing the roller from the roll of used cloth. Furthermore, a smooth surface may be easier to clean. This may be especially important with regard to sanitary facilities. - The roll comprises a
groove 5 axially extending from oneend part 61 of theroll 2 to anotherend part 62 of theroll 2. The end parts are only visible inFIG. 1C . Thegroove 5 is open on the oneend part 61. Thegroove 5 may have a substantially semi circular shape, but it may also be tapered. The winding roller comprises afreestanding pin 7 that is connected to the anotherend part 62, forming agap 8 between thegroove 5 and thepin 7 into which the strip material may be slid from the oneend part 61 where thegroove 5 is open. -
Fig. 1C shows a schematic representation of a cross-section B - B' of the winding roller as indicated inFIG. 1A . Besides all the elements already shown inFIG. 1B , this cross-section clearly shows theend parts pin 7 to thecylindrical roll 2. In thisembodiment pin 7 has the same length as thecylindrical roll 2. Thepin 7 may also be of a different length, e.g. shorter than thecylindrical roll 2. Preferably, the surface of thegroove 5 and the surface of thepin 7 are smooth. This may make it easier to slide the cloth into thegap 8 while connecting the clean cloth to the windingroller 1. Furthermore, smooth surfaces may be easier to clean. This may be especially important with regard to sanitary facilities. - The freestanding
pin 7 is positioned in thegroove 5, below thewinding surface 4 of the roll. Thedashed line 41 shows thewinding surface 4 above thegroove 5. Thedashed lines 41 makes it clear that the freestandingpin 7 is positioned below thewinding surface 4 of the roll. In this position, thepin 7 does not protrude above thewinding surface 4 of the roll. This position of thepin 7 may make it easier to remove the windingroller 1 from the roll of used cloth. - The
gap distance 9 between thegroove 5 and thepin 7 is at least the width of the flat strip material in an uncompressed state. With thisgap distance 9, the strip material is not compressed when slid into thegap 8 and therefore not clamped in thegap 8. Thewinding roller 1 may be easier removed from the roll of used cloth, when the cloth is not clamped in thegap 8. Furthermore, agap distance 9 whereby the cloth is not clamped in thegap 8 may also make it easier to slide the end part of the clean cloth into thegap 8. -
FIG. 2 shows a view of an exemplary embodiment of the replaceable winding roller according to the present invention from three perspectives respectively shown inFIGS. 2A, 2B and 2C . In the following,FIG. 2 will be referred to as regardingFIGS. 2A, 2B and 2C . If a certain aspect may only be seen in one of the figures or an aspect may particularly well be seen in one of these figures, there will be explicit reference to this figure. - After sliding the free end of the clean cloth into the gap 8 (see
Fig 1B ), the roller may be rotated a couple of times to stably connect the clean cloth to the windingroller 100. The embodiment of thewinding roller 100 shown inFIG. 2 comprises aturning element 10.FIG. 2A and 2B show the turning element on the side of thecylindrical roll 2 where the groove 5 (seeFig 1B ) is open, the turningelement 10 on the other side of the roller is shown inFIG. 2C . The turningelements 10 may be helpful for rotating the roll a couple of times to stably connect the clean cloth to the windingroller 100. - The embodiment of the winding
roller 100 as shown inFIG. 2 comprises aflange 11 on the another end part 62 (seeFig 1C ) of the roller where the pin 7 (seeFig 1B ) is connected to the roller. Theflange 11 may align the various layers of cloth during winding and therefore stabilize the roll of used cloth on the windingroller 100. - In the embodiment of the winding
roller 100 shown inFIG. 2 , the one end part 61 (seeFig 1C ) of the roll, i.e. the part of the roller where thegroove 5 is open and where the strip material may be slid in, does not comprise aflange 11. This makes it possible to pull on the anotherend part 62 of theroll 2, i.e. the part of the roller where thepin 7 is connected to theroller 100, and remove the cylindrical roll 2 (seeFig 1B ) from the wound up roll of used cloth. Aflange 11 on the oneend part 61 would impede removing the roller from a roll of cloth without unrolling the roll of cloth. - To make it easier among others to slide the towel into the
gap 8, the embodiment of the winding roll shown inFIG. 2 and especially inFIGS. 2A and 2B comprises a slant recessedcylinder surface 12 on the one end of the roller where thegroove 5 is open. - For cost effective manufacturing, a winding roller comprising a
groove 5 and apin 7, may be manufactured in one piece. A typical way of manufacturing a winding roller in one piece is via injection moulding. In injection moulding, a mass of viscous material is injected under high pressure in a mould in the form of the desired product. After cooling the synthetic material in the mould, the desired product may be obtained. The mass of the typically synthetic viscous material is preferably provided as a granulated material or as a powder and melted into a viscous mass. - The replaceable winding roller according to the present invention may be comprised in a towel dispenser.
- The detailed drawings, specific examples and particular formulations given serve the purpose of illustration only. Furthermore, other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the exemplary embodiments without departing from the scope of the invention as expressed in the appended claims.
