Definitions
- This invention relates to a method for the application of tape to a surface, and particularly but not exclusively to a method of manually applying tape to a surface using a hand-held tape applicator.
- tape encompasses single-sided adhesive tapes, double-sided adhesive tapes, duct tapes, masking tapes, cloth tapes, sealant tapes, PVC tapes, packaging films, protective films and other strips of material that may be applied to surfaces.
- protective films The description below relates protective films but it will be appreciated that the present invention is not limited to the application of protective films.
- Protective films are designed to protect surfaces from scratching, scuffing, marking and other damage. It is common practice to apply a protective film to the surface of a product immediately following the manufacture thereof. In this way, the newly manufactured product is protected from surface damage during transit and/or storage.
- the use of protective film is not limited to newly manufactured products, for example it is common for removals companies to apply protective film to household furniture prior to packaging the furniture into the removals vehicle.
- a typical machine for this purpose comprises a first series of rollers for driving and guiding the product through the machine.
- the machine further comprises a second series of rollers for drawing the protective film from a supply reel and directing it towards the surface to be protected.
- the second series of rollers includes pressure rollers for bringing the protective film into contact with the surface and applying pressure thereupon to adhere the film to the surface.
- Another problem is that the machinery has to be appropriate to the specific product to which the film is to be applied.
- the position of the pressure rollers must be appropriate to the height of the product, and the width of the machinery must be sufficient to accommodate the full width of the product.
- the machinery must be adapted to cope with this.
- the second approach namely the application of film by hand with little or no equipment, is typically adopted by removals companies when applying protective film to household furniture prior to packing the furniture into the removals vehicle.
- One advantage of this approach is that the manual application method may be easily adapted according to the nature of the goods to which the film is to be applied: there are no restrictions regarding the length, width, surface contours etc. Furthermore, no additional space other than the space required to change the orientation of the goods is required in order to cover the surfaces of the goods with protective film.
- the manual approach to the application of protective film has a number of significant drawbacks.
- One major drawback of the manual application of protective film is that it is a labour-intensive and time-consuming process.
- GB872896 and JPH0952652A each disclose a method of applying tape to a target surface, the method comprising the steps of:
- the re-orientating step acts to displace the third roller so as to extend a blade which cuts the tape.
- a method of the kind disclosed in GB872896 and JPH0952652A for applying tape to a target surface which is characterised in that the tape is thereby brought into contact with the target surface by the second and third rollers to apply pressure thereupon and to adhere the tape to the surface when the applicator is urged further along the target surface in a direction substantially perpendicular to the longitudinal axes of the rollers.
- the side of the tape that faces radially inwards when the tape is coiled around the reel is preferably arranged to face radially outwardly when the tape is passed over the rollers. It is envisaged that this side of the tape will be adhesive.
- the present invention is not limited to adhesive tape, for example the surface to which the tape is to be applied may be coated with adhesive prior to applying the tape.
- a tape applicator may be operated in at least two operating orientations rotated relative to one another about an axis parallel to the longitudinal axes of the rollers, this axis may be coincident with the handle portion.
- the first tangent plane is substantially parallel to the plane of the target surface and first and second rollers bring the tape into contact with the target surface and apply pressure thereupon to adhere the tape to the surface.
- the tape thus passes between the first and second rollers and the surface when the applicator is orientated in the first operating orientation.
- the second tangent plane is substantially parallel to the plane of the target surface and the second and third rollers bring the tape into contact with the target surface and apply pressure thereupon to adhere the tape to the surface.
- the tape thus passes between the second and third rollers and the surface when the applicator is orientated in the second operating orientation.
- the tape applicator may be gripped by a user via the handle portion and manually pushed or pulled in a direction substantially perpendicular to the longitudinal axes of the rollers. It is envisaged that the tape applicator will be pushed or pulled from a first longitudinal edge of a surface to the opposing longitudinal edge of the surface.
- the tape is passed from the reel to the first roller, from the first roller to the second roller and, if operated in the second operating orientation, from the second roller to the third roller.
- the frictional engagement between the tape and the first and second rollers, or the second and third rollers provides the forces required to unwind the tape from the reel. It will also be appreciated that the process of adhering the tape to the target surface is assisted by the weight of the applicator on the surface and any additional pressure towards the surface applied by the user.
- the invention provides many of the above-described advantages of manual tape application.
- the translation of the applicator in relation to the surface of the goods obviates the requirement for a clearance space of at least twice the length of the goods to be covered.
- Another advantage is that a power source is not required and hence avoids fuel costs and ensures full portability without the drawbacks associated with portable power supplies.
- the present invention avoids a number of the above-described drawbacks associated with the manual application of tape to a surface.
- the applicator used in the method facilitates the accurate positioning of tape.
- the longitudinal edges of the first, second and/or third rollers may be aligned with a lateral edge of the surface or an adjacent strip of tape in order to ensure that the applicator is appropriately directed, namely to ensure that the strip of tape applied by the applicator will abut the lateral edge of the surface or the adjacent strip of tape without gaps or overlap.
- the applicator also assists the user in simultaneously unwinding the protective film from the supply reel and applying the unwound portion of the film to the surface of the goods. It will be appreciated that this greatly enhances the efficiency of the tape application process.
- the obtuse angle defined between the first and second tangent planes may be between 100 degrees and 150 degrees.
- the radial distance between the first and second rollers is less than the radial distance between the second and third rollers. It is advantageous to provide a short radial distance between rollers in order to ensure that at least two rollers engage with the surface in as short a distance as possible with respect to the starting longitudinal edge of the surface. However, a larger radial distance between rollers enables the user to more accurately utilise the alignment of the longitudinal edges of the rollers with respect to the lateral edge of the surface or an adjacent strip of tape in order to point the applicator in an appropriate direction.
- the applicator will be initially orientated in the first orientation described above and subsequently tilted to the second orientation, the first orientation, thereby providing the shorter radial distance between rollers desired immediately upon commencement of application of a new strip of tape, and the second orientation providing the longer radial distance between rollers desired for the remainder of the application process.
- the first, second and third rollers may be arranged in a substantially arcuate shape about the handle portion.
- One advantage of this arrangement is that it minimises the angle through which each roller redirects the tape, thereby reducing the risk of the strain on the tape over the roller and hence the risk of the tape tearing or the like.
- the mounting means may comprise an elongate mounting member arranged to fit within the central aperture of the reel.
- the reel may rotate relative to an outer surface of the mounting member.
- the mounting member may comprise an outer sleeve arranged to rotate relative to an inner core.
- the reel may frictionally engage the outer surface of the outer sleeve when mounted in the tape applicator, the rotation of the reel being provided by the rotation of the outer sleeve relative to the inner core.
- the tape applicator further comprises guide means for guiding the tape from the reel to the first roller.
- the guide means may comprise a guide roller.
- the guide roller may form part of the actuate shape that may be defined by the first, second and third rollers.
- the rollers are may be cylindrical.
- the radii of the first, second and third rollers may be substantially equal to one another.
- the radius of the guide roller may be smaller than the radii of the first, second and third rollers.
- the first, second and third rollers may comprise a rubber coating for minimising the risk of damage to the surface during application of the tape.
- the tape applicator may further comprise cutting means arranged for cutting the tape.
- the cutting means may be arranged for cutting the tape at a location in the first tangent plane.
- the cutting means may comprise a cutting blade arranged to extend in a plane substantially perpendicular to the first tangent plane.
- the cutting blade may comprise a cutting edge, which may be serrated.
- the cutting blade may be reconfigurable between a disengaged configuration in which the cutting blade is spaced apart from the first tangent plane and an engaged configuration in which the cutting blade intersects the first tangent plane.
- the cutting blade may be biased towards the disengaged configuration by means of a spring or the like.
- the cutting means may comprise a manually-operated trigger mechanism for reconfiguring the cutting blade between the disengaged and engaged configurations.
- the trigger mechanism may comprise a finger portion arranged for receiving a user's finger whilst the user grips the handle portion of the applicator.
- the finger portion may be mechanically coupled to the cutting blade such that the cutting blade is reconfigured to the engaged configuration when the finger portion is pulled towards the handle portion of the applicator.
- the step of re-orientating the tape applicator such that the second tangent plane is parallel to and physically abuts the target surface is preferably performed when the distance between the second roller and the longitudinal edge of the target surface is at least equal to the radial spacing between the second and third rollers. More preferably, the step of re-orientating the tape applicator such that the second tangent plane is parallel to and physically abuts the target surface is performed when the distance between the second roller and the longitudinal edge of the target surface is equal to the radial spacing between the second and third rollers.
- the step of re-orientating the applicator may comprise pivoting the tape applicator about the second roller such that the tape is pressed between the target surface and the second roller as the tape applicator is re-orientated.
- the step of urging the applicator along the target surface may comprise manually pushing or pulling the applicator along the target surface.
- the method may further comprise the steps of mounting a reel of tape on the mounting means of the tape applicator and passing the tape over at least the first roller. It is envisaged that these steps will be performed when commencing taping with a new reel of tape.
- the reel of tape may be pre-loaded within the applicator, for example if the applicator has been previously used for applying tape from the reel.
- the method may further comprise the step of applying pressure to the applicator, said pressure being directed towards the target surface.
- the step of applying pressure to the applicator is performed concurrently with the step of urging the applicator along the target surface.

Description
- This invention relates to a method for the application of tape to a surface, and particularly but not exclusively to a method of manually applying tape to a surface using a hand-held tape applicator.
- As used herein, the term "tape" encompasses single-sided adhesive tapes, double-sided adhesive tapes, duct tapes, masking tapes, cloth tapes, sealant tapes, PVC tapes, packaging films, protective films and other strips of material that may be applied to surfaces. The description below relates protective films but it will be appreciated that the present invention is not limited to the application of protective films.
- Protective films are designed to protect surfaces from scratching, scuffing, marking and other damage. It is common practice to apply a protective film to the surface of a product immediately following the manufacture thereof. In this way, the newly manufactured product is protected from surface damage during transit and/or storage. However, the use of protective film is not limited to newly manufactured products, for example it is common for removals companies to apply protective film to household furniture prior to packaging the furniture into the removals vehicle.
- Currently there are two common practices for applying protective film. One approach is to use large dedicated machinery and the other is to simply apply the film by hand with little or no equipment.
- The former approach is typically adopted in manufacturing facilities, the specialist machinery for applying protective film to the newly manufactured product defining a final stage in the manufacturing process. A typical machine for this purpose comprises a first series of rollers for driving and guiding the product through the machine. The machine further comprises a second series of rollers for drawing the protective film from a supply reel and directing it towards the surface to be protected. The second series of rollers includes pressure rollers for bringing the protective film into contact with the surface and applying pressure thereupon to adhere the film to the surface.
- One problem with the use of such machines is that the entire length of the product must be passed under the pressure rollers, and hence the machine requires a clearance space of at least twice the length of the product to be covered. This is particularly problematic when applying protective film to large products such as vehicle body parts or large glazing panels.
- Another problem is that the machinery has to be appropriate to the specific product to which the film is to be applied. For example, the position of the pressure rollers must be appropriate to the height of the product, and the width of the machinery must be sufficient to accommodate the full width of the product. Furthermore, if the upper surface of the product is uneven, for example if the surface is undulating, then the machinery must be adapted to cope with this.
- Yet another problem is that such machines are generally expensive to buy and maintain as a result of the large number of component parts of such machines and the complexity thereof.
- Furthermore, due to the large number of component parts and the requirement for the machines to support the goods to which the protective film is to be applied, such machines are typically large and heavy. This poses problems in relation to the flexibility and portability of the machines.
- The second approach, namely the application of film by hand with little or no equipment, is typically adopted by removals companies when applying protective film to household furniture prior to packing the furniture into the removals vehicle. One advantage of this approach is that the manual application method may be easily adapted according to the nature of the goods to which the film is to be applied: there are no restrictions regarding the length, width, surface contours etc. Furthermore, no additional space other than the space required to change the orientation of the goods is required in order to cover the surfaces of the goods with protective film. However, the manual approach to the application of protective film has a number of significant drawbacks. One major drawback of the manual application of protective film is that it is a labour-intensive and time-consuming process. Furthermore, it is difficult for a user to simultaneously unwind the protective film from the supply reel and apply the unwound portion of the film to the surface of the goods. It has been found that seemingly minor errors in application of the protective film, for example a small delay in applying pressure to the protective film, result is significant defects in the applied film. It has also been found that it is difficult to accurately guide the protective film in the desired direction. For example, it is easy to accidentally veer leftwards or rightwards when applying the film, thereby leaving a region of the surface uncovered.

GB872896 JPH0952652A - providing a tape applicator comprising a frame, a handle portion provided on the frame, mounting means for mounting a reel of tape on the frame, and first, second and third exposed rollers mounted on the frame, the rollers comprising substantially parallel longitudinal axes, a first tangent plane being defined between the first and second rollers and a second tangent plane being defined between the second and third rollers, the angle defined between the first and second tangent planes being obtuse and the handle portion being located within the obtuse angle;
- orientating the tape applicator such that the first tangent plane defined between the first and second rollers is parallel to and physically abuts the target surface, the tape thereby being brought into contact with the target surface by the first and second rollers to apply pressure thereupon and to adhere the tape to the surface when the applicator is urged along the target surface in a direction substantially perpendicular to the longitudinal axes of the rollers; and
- re-orientating the tape applicator such that the second tangent plane defined between the second and third rollers is parallel to and physically abuts the target surface.
- The re-orientating step acts to displace the third roller so as to extend a blade which cuts the tape.
- We have now devised a method of tape application that alleviates at least some of the above-mentioned problems.
- In accordance with the present invention, there is provided a method of the kind disclosed in
GB872896 JPH0952652A - The side of the tape that faces radially inwards when the tape is coiled around the reel is preferably arranged to face radially outwardly when the tape is passed over the rollers. It is envisaged that this side of the tape will be adhesive. However, the present invention is not limited to adhesive tape, for example the surface to which the tape is to be applied may be coated with adhesive prior to applying the tape.
- A tape applicator may be operated in at least two operating orientations rotated relative to one another about an axis parallel to the longitudinal axes of the rollers, this axis may be coincident with the handle portion.
- In a first operating orientation, the first tangent plane is substantially parallel to the plane of the target surface and first and second rollers bring the tape into contact with the target surface and apply pressure thereupon to adhere the tape to the surface. The tape thus passes between the first and second rollers and the surface when the applicator is orientated in the first operating orientation. In a second operating orientation, the second tangent plane is substantially parallel to the plane of the target surface and the second and third rollers bring the tape into contact with the target surface and apply pressure thereupon to adhere the tape to the surface. The tape thus passes between the second and third rollers and the surface when the applicator is orientated in the second operating orientation.
- In use, the tape applicator may be gripped by a user via the handle portion and manually pushed or pulled in a direction substantially perpendicular to the longitudinal axes of the rollers. It is envisaged that the tape applicator will be pushed or pulled from a first longitudinal edge of a surface to the opposing longitudinal edge of the surface. The tape is passed from the reel to the first roller, from the first roller to the second roller and, if operated in the second operating orientation, from the second roller to the third roller. It will be appreciated that the frictional engagement between the tape and the first and second rollers, or the second and third rollers, provides the forces required to unwind the tape from the reel. It will also be appreciated that the process of adhering the tape to the target surface is assisted by the weight of the applicator on the surface and any additional pressure towards the surface applied by the user.
- The invention provides many of the above-described advantages of manual tape application. For example, the translation of the applicator in relation to the surface of the goods obviates the requirement for a clearance space of at least twice the length of the goods to be covered. Another advantage is that a power source is not required and hence avoids fuel costs and ensures full portability without the drawbacks associated with portable power supplies.
- Furthermore, the present invention avoids a number of the above-described drawbacks associated with the manual application of tape to a surface. For example, the applicator used in the method facilitates the accurate positioning of tape. In particular, the longitudinal edges of the first, second and/or third rollers may be aligned with a lateral edge of the surface or an adjacent strip of tape in order to ensure that the applicator is appropriately directed, namely to ensure that the strip of tape applied by the applicator will abut the lateral edge of the surface or the adjacent strip of tape without gaps or overlap. The applicator also assists the user in simultaneously unwinding the protective film from the supply reel and applying the unwound portion of the film to the surface of the goods. It will be appreciated that this greatly enhances the efficiency of the tape application process.
- The obtuse angle defined between the first and second tangent planes may be between 100 degrees and 150 degrees.
- The radial distance between the first and second rollers is less than the radial distance between the second and third rollers. It is advantageous to provide a short radial distance between rollers in order to ensure that at least two rollers engage with the surface in as short a distance as possible with respect to the starting longitudinal edge of the surface. However, a larger radial distance between rollers enables the user to more accurately utilise the alignment of the longitudinal edges of the rollers with respect to the lateral edge of the surface or an adjacent strip of tape in order to point the applicator in an appropriate direction. It is envisaged that the applicator will be initially orientated in the first orientation described above and subsequently tilted to the second orientation, the first orientation, thereby providing the shorter radial distance between rollers desired immediately upon commencement of application of a new strip of tape, and the second orientation providing the longer radial distance between rollers desired for the remainder of the application process.
- The first, second and third rollers may be arranged in a substantially arcuate shape about the handle portion. One advantage of this arrangement is that it minimises the angle through which each roller redirects the tape, thereby reducing the risk of the strain on the tape over the roller and hence the risk of the tape tearing or the like.
- The mounting means may comprise an elongate mounting member arranged to fit within the central aperture of the reel. The reel may rotate relative to an outer surface of the mounting member. Alternatively, the mounting member may comprise an outer sleeve arranged to rotate relative to an inner core. In the latter case, the reel may frictionally engage the outer surface of the outer sleeve when mounted in the tape applicator, the rotation of the reel being provided by the rotation of the outer sleeve relative to the inner core.
- The tape applicator further comprises guide means for guiding the tape from the reel to the first roller. The guide means may comprise a guide roller. The guide roller may form part of the actuate shape that may be defined by the first, second and third rollers.
- The rollers are may be cylindrical. The radii of the first, second and third rollers may be substantially equal to one another. The radius of the guide roller may be smaller than the radii of the first, second and third rollers.
- The first, second and third rollers may comprise a rubber coating for minimising the risk of damage to the surface during application of the tape.
- The tape applicator may further comprise cutting means arranged for cutting the tape. The cutting means may be arranged for cutting the tape at a location in the first tangent plane. One advantage of this arrangement is that the second and third rollers are available for adhering the portion of tape that has been severed from the body of tape on the reel to the surface. Furthermore, the body of tape that remains after cutting the tape passes from the reel and over the first roller, thereby enabling a user to easily locate the tail of the tape and to re-commence application of the tape.
- The cutting means may comprise a cutting blade arranged to extend in a plane substantially perpendicular to the first tangent plane. The cutting blade may comprise a cutting edge, which may be serrated. The cutting blade may be reconfigurable between a disengaged configuration in which the cutting blade is spaced apart from the first tangent plane and an engaged configuration in which the cutting blade intersects the first tangent plane. The cutting blade may be biased towards the disengaged configuration by means of a spring or the like. The cutting means may comprise a manually-operated trigger mechanism for reconfiguring the cutting blade between the disengaged and engaged configurations. The trigger mechanism may comprise a finger portion arranged for receiving a user's finger whilst the user grips the handle portion of the applicator. The finger portion may be mechanically coupled to the cutting blade such that the cutting blade is reconfigured to the engaged configuration when the finger portion is pulled towards the handle portion of the applicator.
- The step of re-orientating the tape applicator such that the second tangent plane is parallel to and physically abuts the target surface is preferably performed when the distance between the second roller and the longitudinal edge of the target surface is at least equal to the radial spacing between the second and third rollers. More preferably, the step of re-orientating the tape applicator such that the second tangent plane is parallel to and physically abuts the target surface is performed when the distance between the second roller and the longitudinal edge of the target surface is equal to the radial spacing between the second and third rollers. It is particularly advantageous to re-orientate the applicator if the radial spacing between the second and third rollers is greater than the radial spacing between the first and second rollers, the applicator being reconfigured to the configuration with the greater spacing between rollers when it is possible for both the second and third rollers to individually press the tape onto the surface.
- The step of re-orientating the applicator may comprise pivoting the tape applicator about the second roller such that the tape is pressed between the target surface and the second roller as the tape applicator is re-orientated.
- The step of urging the applicator along the target surface may comprise manually pushing or pulling the applicator along the target surface.
- The method may further comprise the steps of mounting a reel of tape on the mounting means of the tape applicator and passing the tape over at least the first roller. It is envisaged that these steps will be performed when commencing taping with a new reel of tape. Alternatively, the reel of tape may be pre-loaded within the applicator, for example if the applicator has been previously used for applying tape from the reel.
- The method may further comprise the step of applying pressure to the applicator, said pressure being directed towards the target surface. Preferably the step of applying pressure to the applicator is performed concurrently with the step of urging the applicator along the target surface.
- An embodiment of the present invention will now be described by way of example only and with reference to the accompanying drawings, in which:
-
Figure 1 is a side view of a tape applicator for use in a method of the present invention; -
Figure 2 is a perspective view of the tape applicator offigure 1 ; and, -
Figure 3 is a flow diagram of method in accordance with the present invention of applying tape to a surface. - Referring to
Figure 1 of the drawings, there is illustrated atape applicator 10 for applying tape to a target surface. Theapplicator 10 comprises a series ofrollers parallel frame portions - The series of rollers includes first, second and third
exposed pressure rollers rollers rollers rollers roller - The first and
second frame portions first frame portion 12 is formed of first and second substantiallyelongate arms rollers first frame portion 12 such that the longitudinal axes of therollers first frame portion 12. Thefirst roller 11a is coupled to thefirst frame portion 12 at a distal end of thefirst part 12a of thefirst frame portion 12. Similarly, thesecond roller 11b is coupled to thefirst frame portion 12 at a proximal end of thesecond part 12b of thefirst frame portion 12 and thethird roller 11c is coupled at a distal end of thesecond part 12b of thefirst frame portion 12. A first tangent plane P1 is defined between the first and second rollers and a second tangent plane P2 is defined between the second and third rollers. The radial distance between the second andthird rollers second rollers - The
second frame portion 13 includes a handle having a ribbed hand-grip 14 formed of an elastomeric or plastics material. A space is formed intermediate the hand-grip 14 and thesecond roller 11b to accommodate a user's fingers. The longitudinal axis of the hand-grip 14 extends substantially perpendicular to the polar axis of thesecond roller 11b such that, when gripped, the arm of the user extends in a substantially radial direction with respect to thesecond roller 11b. - The
second frame portion 13 also includes a mountingmember 15 for mounting a reel oftape 20 to thesecond frame portion 13. The mountingmember 15 extends substantially perpendicularly to thesecond frame portion 13 towards thefirst frame portion 12. The mountingmember 15 comprises anouter sleeve 15a arranged to rotate relative to aninner core 15b, the inner cylindrical side wall of the reel oftape 20 being arranged to frictionally engage outwardly protruding portions of thesleeve 15a when thereel 20 is mounted on the mountingmember 15. Accordingly, in use, thereel 20 rotates about an axis substantially parallel to the longitudinal axes of therollers outer sleeve 15a may be detachably coupled to theinner core 15b and a plurality ofouter sleeves 15a of different outer diameters may be supplied to accommodate reels oftape 20 having differing internal diameters. - The mounting
member 15 is disposed at an end of thesecond frame portion 13 proximal to thefirst roller 11a such that the mountingmember 15, thefirst roller 11a, thesecond roller 11b and thethird roller 11c together form a substantially actuate shape that curves inwardly with respect to the hand-grip 14, the mountingmember 15 and thethird roller 11c being located at opposing ends of the arcuate shape. - A
guide roller 16 is provided on thesecond frame portion 13 intermediate thefirst roller 11a and the mountingmember 15 and closer to the latter. The length of theguide roller 16 is substantially equal to the lengths of the first, second andthird rollers guide roller 16 is substantially smaller than the radii of the first, second andthird rollers guide roller 16 is arranged to rotate about an axis substantially parallel to the longitudinal axes of the first, second andthird rollers reel 20 to theguide roller 16 and subsequently to thefirst roller 11a. Unlike the first, second andthird rollers guide roller 16 is not configured to directly apply tape to the target surface and/or adhere the applied tape thereto. In particular, the tape is not pressed between theguide roller 16 and the target surface. - A
cutting blade 17 is provided for cutting the tape when the desired area of the target surface has been covered. Theblade 17 includes a serrated edge to assist cutting of the tape. Thecutting blade 17 extends between the first andsecond frame portions blade 17 being substantially parallel to the longitudinal axes of therollers cutting blade 17 is disposed intermediate the first andsecond rollers cutting blade 17 is reconfigurable between a disengaged configuration in which the cutting blade is spaced apart from the first tangent plane P1 and a second configuration in which the cutting blade intersects the first tangent plane P1 so as to cut the tape. The length of theblade 17 is sufficient to ensure that the full width of the tape is cut when theblade 17 is reconfigured to the engaged configuration. The cutting blade is biased towards the disengaged configuration by means of a spring (not shown) and is manually reconfigured to the engaged configuration by means of finger-operated trigger mechanism. The trigger mechanism includes finger portion (not shown) located at a suitable position with respect to the hand-grip 14. In use, the cutting blade is pulled towards the engaged configuration when the finger portion is pulled towards the hand-grip 14. - With particular reference to
figure 3 , in order to apply tape to a target surface, a user initially mounts the reel oftape 20 on the mountingmember 15 of thetape applicator 10 atstep 101. The user then passes the free end of the tape from thereel 20, over theguide roller 16 and over thefirst pressure roller 11a atstep 102. - At
step 103, the user grips theapplicator 10 via the hand-grip 14 and orientates theapplicator 10 such that the first tangent plane P1 is substantially parallel to the target surface. - With the
applicator 10 in this orientation, atstep 104 the user engages the tape disposed on thefirst roller 11a with the target surface such that the tape is pressed between the target surface and thefirst roller 11a. It is envisaged that the user will align the longitudinal axis of thefirst roller 11a with a first longitudinal edge of the target surface and the longitudinal edge of thefirst roller 11a with the lateral edge of the target surface. - At
step 105, the user pushes theapplicator 10 away from the first longitudinal edge of the target surface in a direction substantially perpendicular to the longitudinal axis of thefirst roller 11a, the orientation of theapplicator 10 being maintained in this step. Initially, the tape is applied to the target surface via thefirst roller 11a only, but once the distance from thefirst roller 11a to the first longitudinal edge the target surface becomes greater than the distance between the first andsecond rollers second rollers 11b applies additional pressure to the tape applied to the target surface by thefirst roller 11a, thereby improving the adhesion of the tape to the surface. It is envisaged that the user will align the longitudinal edges of thefirst roller 11a and, when applicable, thesecond roller 11b with a lateral edge of the surface in order to ensure that theapplicator 10 is appropriately directed, namely to ensure that the strip of tape applied by the applicator will abut the lateral edge of the surface without gaps or overlap. - Once the distance from the
second roller 11b to the first longitudinal edge of the target surface is equal to the distance between the second andthird rollers applicator 10 atstep 106. In detail, the user pivots theapplicator 10 about thesecond roller 11b such that thefirst roller 11a becomes elevated above the target surface. In the new orientation, the second tangent plane P2 is substantially parallel to the target surface and the second andthird pressure rollers - The user continues to push the
applicator 10 away from the first longitudinal edge of the target surface in a direction substantially perpendicular to the longitudinal axes of therollers second roller 11b reaches the second longitudinal edge of the target surface. Again, it is envisaged that the user will align the longitudinal edges of the second andthird rollers applicator 10 is appropriately directed, namely to ensure that the strip of tape applied by the applicator will abut the lateral edge of the surface without gaps or overlap. - The user then pulls the finger-trigger at
step 107 to reconfigure thecutting blade 17 into the engaged configuration and hence cut the tape. The tape extends forwardly of thesecond roller 11b and thus the user may wish to finely trip the tape to ensure that the end of the tape is flush with the second longitudinal edge of the target surface. Alternatively, the user may pull the finger-trigger atstep 107 when the distance between thesecond roller 11b and the second longitudinal edge of the target surface is equal to the distance between thesecond roller 11b and thecutting blade 17. It is envisaged that as the user becomes more experienced in using the applicator he will become more capable of judging this distance and will hence adopt the latter approach. If the width of the target surface is greater than the width of the tape, the user recommences the taping process at the first longitudinal edge of the target surface, mirroringsteps 103 to 107 but aligning the lateral edges of the first, second, and/orthird rollers applicator 10 is appropriately directed. - From the foregoing therefore, it is evident that the present invention provides a simple yet effective method of applying tape to a surface.
