Definitions
- the present invention relates to a dispenser for dispensing cut lengths of material strip, in particular but not exclusively cut lengths of foil strip, and/or a method of dispensing cut lengths of material strip.
- foil strips When applying colour to hair, foil strips may be used, particularly if only certain sections of hair require colouring, e.g. when applying highlights to hair.
- Each foil strip is generally folded at one end. A section of hair for colouring is selected and the folded end of the strip is then placed near the roots of the selected hair. Hair dye is applied to the selected hair. The strip is then folded back on itself, and often the side edges of the foil are also folded, to encase the hair and hair dye between the foil (i.e. a foil wrap is formed).
- dispensers are often used to dispense the foil strips. Electrical dispensers are particularly useful because the length of the dispensed strip can often be customised to suit the length of the hair to be dyed.
- GB2436831, WO03/062110 and EP1590286 disclose examples of electronic dispensers.
- a first aspect of the invention provides a dispenser for dispensing cut lengths of material strip of the type capable of maintaining a crease, the dispenser comprising: a guide for guiding a strip of material through the dispenser; a cutter for cutting a material strip to a desired length; a folder for folding an end of a strip of material; and a link between the cutter and the folder for causing movement of the cutter and folder when one of the cutter or folder is moved by a predetermined amount in one of a first or second direction to actuate cutting or folding; and a drive mechanism for driving movement of the cutter and/or the folder, wherein the drive mechanism is configured for causing movement in two directions, such that movement in one of the first or second direction actuates cutting of the strip material and movement in the other of the first or second direction actuates folding.
- the dispenser provides an improved alternative dispenser to those of the prior art. Further, driving the cutter or folder in one direction for cutting and in another direction for folding, means that a user can easily select when to actuate cutting or folding, which gives a user the option to select not to fold an end of a cut length of material strip. Yet further still, the dispenser is less complex and can be cheaper to manufacture than dispensers of the prior art.
- the strip of material may be a foil strip or a saran strip.
- the cut and folded strip of material may be used in a hair dying procedure.
- the predetermined amount refers to an amount sufficient to actuate cutting or folding.
- the drive mechanism drive may be a rotary drive.
- the first direction and second directions may be opposed directions.
- the first direction may be clockwise or anti-clockwise
- the second direction may be anti-clockwise or clockwise.
- the drive mechanism may drive the folder.
- the link between the cutter and the folder may be such that when the folder is moved by a predetermined amount in the first direction cutting is actuated. Movement of the folder by a predetermined amount in the second direction may actuate folding.
- a reaction member may be shaped and positioned to provide a reaction surface against which the folder can push, in use, with a strip of material therebetween, to create a fold in said strip of material.
- the provision of the reaction surface improves the fold formed in an end of the length of material.
- a tight fold is preferred by hairdressers as it eases the application of dye to strands of hair.

- the motors 42, 52 are electric, and one or both may e.g. be a stepper motor such that accurate positioning may be achieved.
- the drive belt 54 and/or drive belt 60 may be a toothed belt or a chain. In alternative embodiments, a series of gears or an additional motor and no drive connection may be provided instead of using a drive belt.
- the output feed rollers 48 and 50 are provided with complementary relief surfaces in order that the foil strip 16 passing between them is embossed with a pattern.
- the pattern may cover the whole of the roller surfaces or just a portion. In some embodiments, the pattern may be functional - e.g. to increase the rigidity of the foil strip, or have an aesthetic function - e.g. to show the machine brand, or the name/logo of the hair salon in which the machine is used.
- the driven output feed roller i.e.
- the lower feed roller in the present embodiment may have a relief surface defining a pattern for embossing
- the other output feed roller i.e. the upper feed roller in the present embodiment
- CSPE CSM chlorosulfonated polyethylene synthetic rubber
- a dabber 74 is connected to the tray 14.
- the dabber 74 has an arm 76 resiliently connected to the tray 14. At a free end of the arm 76 there is provided a temporary adhesive 78 for adhering to a length of foil strip positioned in the tray 14 when the arm is brought into contact therewith.
- the tray 14 removably connects to the casing 12. For example, using a lug and slot arrangement.
- the tray 14 may also be electrically connected to an electrical system of the dispenser, such that the dispenser can detect whether or not the tray is connected.
- the tray may not be removably connected to the casing, and instead may be permanently connected or may be removably or permanently connected to a component housed within the casing, for example a chassis 84 (described later).
- the tray 14 is not adjustable. However, in alternative embodiments the tray may be adjustable in length.
- FIG 26 an example of a dispenser 10b with an adjustable tray 14b is shown.
- the tray 14b is provided in two parts: a main part 66b and an extension part 68b.
- the main part connects to the extension part by a lug 70b and slot 72b on each side of the tray.
- the lugs are provided on the main part 66b and the slots 72b are provided on the extension part 68b.
- the slot 72b is slidable relative to the lug 70b so that the length of the tray 14b can be adjusted.
- the casing 12 has a hinged lid 80.
- the lid 80 may be lifted away from a main body of the casing 12 to access the dispensing mechanism. Access may be required to load a roll 82 of foil strip into a cradle of the dispenser, or to solve any blockages or operating problems with the dispenser (should they arise).
- the lower feed rollers 44, 48 are mounted in a chassis 84 and the upper rollers 46, 50 are mounted in a clamp tray 86.
- the clamp tray 86 is clamped to the chassis 84, using spring tabs, so as to mount the upper rollers on top of the lower rollers, in such a close contact that the upper and lower rollers compress a foil strip placed therebetween.
- the clamp tray 86 is connected to the chassis 84 by a pivotal connection 88 at an end near where the roll 82 is loaded into the dispenser 10. When the lid 80 is open, the clamp tray 86 may be pivoted away from the chassis 84 so as to enable a user to feed a foil strip from the roll 82 through the input and output feed rollers, or to clear any blockages or operating problems (should they arise).
- a pair of resilient latches 85 extend upwardly from the chassis 84 in order to selectively hold the clamp tray 86 in place when closed.
- a human machine interface (HMI) 90 positioned on the casing 12 is shown.
- the HMI has a display 92 (e.g. LCD) for indicating a user's selection, for example the selected length of each cut length of foil strip, whether the end of the foil is folded or not, and the quantity of cut length of foil strip required.
- the FEVII 90 also includes a start/pause button 96 and a stop/reset button 94.
- the user interface also includes an indicator 100 to show that the power is on and an indicator 98 to show whether the device is connected to a Bluetooth or wireless network.
- a printed circuit board (PCB) 102 is mounted on an inner side of a casing 12 of the dispenser 10, but alternatively the PCB may be mounted at any suitable position, for example on the chassis 84.
- the PCB comprises a microprocessor controller which is used to control the cutting, folding and dispensing mechanism in accordance with the inputs from the HMI 90.
- the PCB may receive inputs from a remote device connected to a Bluetooth or wireless network, or alternatively using infrared or radio waves.
- the PCB may receive inputs from a USB or Ethernet connection, which for example, is connected to a computer or computer network.
- the tray 14 may be connected to an electrical circuit connected to the PCB to inform a control system of the dispenser whether or not the tray 14 is connected to the casing 12 or an internal component of the dispenser (e.g. the chassis 84).
- the lid 80 of the dispenser is lifted to load the roll 82 of foil strip into the cradle of the dispenser.
- a lock and key mechanism may be used to hold the roll 82 in position and ensure only the correct grade of roll is fitted.
- An example of such a mechanism is disclosed in more detail in our co-pending application EP2451733, which is incorporated herein by reference.
- the clamp tray 86 is then lifted and foil strip from the roll 82 is fed over the chassis.
- the clamp tray is then closed on top of the chassis 86 so that the foil strip 16 is compressed between the upper feed rollers 46, 50 and the lower feed rollers 44, 48.
- a user inputs the desired length of the cut foil strip, the quantity required, and in this example selects to have a fold at one end of the foil strip, using the FDVII or a remote device. These inputs are communicated to the PCB 102, which controls the operation of the two motors 40, 52 accordingly.
- the folder 24 is positioned in its "neutral" position so that the guide surface 36 of the folder 24 is aligned with the guide 18 and the foil strip 16 is fed through the dispenser by input feed rollers 44, 46.
- the feed of the foil strip 16 through the dispenser is temporarily stopped when a desired length has been fed through the dispenser 10.
- the folder 24 is rotated anticlockwise about the axis of rotation R so that the cam of 21 of the folder 24 rotates against the curved surface of the holder 29 of the cutter 22, so as to linearly move the cutter 22 towards the foil strip 16.
- the cutter contacts the foil strip 16 through the gap in guide 18 and pushes the foil strip against the block 35.
- Contact of the foil with the blade 26 and the block 35 cuts a downstream portion of the foil strip to a desired length.
- the folder 24 is rotated clockwise about the axis of rotation R so as to again align the guide surface 36 of the folder 24 with the guide 18.
- the feed of the foil strip 16 through the dispenser again commences, and the output feed rollers 48, 50 rotate to feed the cut lengths of foil strip out of the dispenser.
- the output feed rollers 48, 50 rotate at substantially the same speed as the input feed rollers 44, 46.
- the cut length of foil strip exits the dispenser 10 at a faster rate than the strip of foil from the roll 82 advances towards a region where the body 20 is located. This ensures that the cut strip of foil is clear of the cutter 22 and folder 24 before the cutter or folder is actuated.
- the feed of the foil strip through the dispenser temporarily stops.
- the folder 24 then rotates clockwise about the axis of rotation R to rotate the guide surface 36 and the notch 32 through an aperture in the guide 18.
- the folder 24 is rotated until the foil strip 16 is pressed between the notch 32 and the reaction surface 33.
- the position of the axis of rotation R means that the axis of rotation R is offset from both the notch 32 and the reaction surface 33 so that the axis of rotation R is not between the notch 32 and the reaction surface 33. If it were desired for the cut length of foil strip to not have a folded end then this step would not be carried out.
- the folder 24 is rotated anti-clockwise about the axis of rotation R to position the guide surface 36 of the head 31 of the folder 24 in alignment with the guide 18.
- feeding of the foil strip is again commenced, and the foil strip is fed through the dispenser by the input feed rollers 44, 46.
- the fold in the foil strip 16 is fed through the output feed rollers, which compresses and completes the fold in the foil strip (an end of the foil is folded so that the two sides of the fold are substantially parallel and face-contacting).
- the feed of the foil strip through the dispenser is temporarily stopped, and the folder 24 is rotated anti-clockwise to move the blade 26 of the cutter 22 through the aperture in the guide 18, so as to cut the foil strip 16 to a desired length.
- the cut also creates a new leading edge of the foil strip from the roll 82, which can be folded if desired.
- the presently described embodiment provides an alternative improved arrangement for a dispenser to the dispensers of the prior art.
- the arrangement of the folder 24 and the cutter 22 means that the folder 24 can be optionally operated, giving a user flexibility as to whether or not they wish an end of a cut length of foil to be folded.
- the reduced number of components and simplicity of the dispenser 10 means that the complexity and cost of the dispenser can be reduced compared to dispensers of the prior art.
- the dabber 74 provided on the tray 14 means that a user can easily select a length of foil from the tray when needed by depressing the arm into contact with the foil and the arm resiliently moving to a lifted position with the foil having been releasably secured to the adhesive.
- the FDVII 90 permits easy use of the dispenser and provides improved flexibility for the user, e.g. easy selection of length of foil strip or whether to have a folded end, and also prompts for refilling foil roll or how to fix errors. Further the ability to program the PCB via a remote device (e.g. a remote controller designed for use with the dispenser or another portable device such as a mobile phone, computer or computer network) provides added convenience for a user.
- a single body 120 is provided for cutting and folding the foil strip 116, and is shown in more detail in Figure 17.
- the body 120 is rotatably mounted so as to be rotatable about an axis of rotation A.
- the axis of rotation A is offset from a guide surface of the dispenser (and therefore, in use, is offset from the foil), and also offset from both a cutter 122 and folder 124 of the body 120.
- the cutter 122 is provided at one end of the body 120 and the folder 124 is provided at an opposite end of the body 120.
- the body 120 is a substantially elongate body, and the cutter 122 is disposed at one end of the body 120 and the folder 124 is positioned at the other end of the elongate body.
- the cutter 122 may be positioned in any other position with respect to the folder that enables only the cutter or folder to be actuated at any one time.
- the cutter 122 has an elongate blade 126 protruding towards the guide 118, and in use, towards the foil strip 116.
- the blade 126 is angled to be approximately 80° to the guide.
- the blade may be angled at between 90 to 30° to the guide.
- An aperture is formed in the guide 118 (as shown in Figure 18). In use, the blade 126 rotates through the aperture to cut the foil strip 116.
- An abutment surface 130 is provided on the cutter 122 to abut a portion of the guide 118 when the blade 126 rotates through the aperture, so as to prevent over rotation of the cutter 122.
- no abutment surface may be provided.
- the folder 124 comprises a notch 132.
- the notch 132 is substantially V-shaped and the walls of the notch are angled at approximately 45°. However, in alternative embodiments the walls of the notch may be angled at between 20 and 70°.
- the notch is provided for folding the foil to a substantially 45° angle.
- the guide 118 has an aperture 134 through which the folder 124 can rotate.
- the folder 124 has a guide surface 136 angled at approximately 30° to an elongate plane 138 of the body 120 and positioned adjacent the notch 132. The guide surface 136 is positionable in alignment with the guide 118. If no folding is required, the guide surface acts to guide the foil strip 116 through the dispenser.
- the body 120 is rotatable to rotate the guide surface 136 and notch 132 through the aperture 134 in the guide.
- the guide surface 136 then acts to guide a portion of the foil strip 116 into the notch 132 for folding.
- a reaction member 125 is positioned on an opposite side of the foil strip 16 to the body 120.
- the reaction member 125 has a planar surface parallel to a flow of the foil strip 116 through the dispenser 110 for guiding the foil strip through the dispenser 110 and for supporting the foil strip 116 during a cutting process.
- the reaction member 125 has slot 127 positioned and angled to receive a portion of the elongate blade 126 after the elongate blade has cut through the foil strip 16.
- the reaction member 125 has a nose 133.
- the nose 133 is angled at a corresponding angle to the notch 132, so that when the folder is rotated to fold an end of the foil strip 116, the foil strip 116 is folded between the notch 132 and the nose 133.
- the operation of the dispenser 110 will now be described, concentrating mainly on the difference in operation between dispenser 110 and previously described dispenser 10.
- the body 120 is positioned in its "neutral" position so that the guide surface 136 of the folder 124 is aligned with the guide 118 and the foil strip 116 is fed through the dispenser by input feed rollers 144, 146.
- the body 120 is rotated anticlockwise about the axis of rotation A so as to rotate the blade 126 of the cutter 122 through the aperture 128 in the guide 118.
- the blade rotates through the foil strip 116, so as to cut the foil strip, and into the slot 127 of the block 125.
- the block 125 providing support to the foil strip 116 whilst the foil strip is cut.
- the body 120 is rotated clockwise about the axis of rotation A so as to again align the guide surface 36 of the folder 124 with the guide 118.
- the output feed rollers 148, 150 rotate to feed the cut lengths of foil strip out of the dispenser.
- the cut length of foil strip exits the dispenser 110 at a faster rate than the strip of foil from the roll 182 advances towards a region where the body 120 is located.
- the body 120 rotates clockwise about the axis of rotation A to rotate the guide surface 136 and the notch 132 through the aperture 134 in the guide 1 18.
- the rotary motion of the body 120 causes a portion of the foil to enter the notch 132.
- the folder 124 continues to rotate towards the nose 134 of the block 125 and the portion of foil is compressed between the notch 132 and the nose 133 to create a fold in the foil strip, in this embodiment the fold is approximately 45°. If it were desired for the cut length of foil strip to not have a folded end then this step would be omitted.
- the body 120 is rotated anti-clockwise about the axis of rotation A to position the guide surface 136 of the folder 124 in alignment with the guide 118.
- the foil strip is fed through the dispenser by the input feed rollers 144, 146.
- the fold in the foil strip 116 is fed through the output feed rollers, which compresses and completes the fold in the foil strip (i.e. the an end of the foil is folded so that the two sides of the fold are substantially parallel and face-contacting).
- the body 120 is rotated anti-clockwise about the axis of rotation A to rotate the blade 126 of the cutter 122 through the aperture in the guide 118, so as to cut the foil strip 116 to a desired length.
- the cut also creates a new leading edge of the foil strip from the roll 182, which can be folded if desired.
- the presently described embodiment provides an alternative improved arrangement for a dispenser to the dispensers of the prior art.
- the cutter 122 and the folder 124 are part of the same body 120, which enables the dispenser to be compact.
- one pair of input feed rollers and one pair of output feed rollers are provided, but in alternative embodiments any number of feed rollers may be provided at the input, output or along a flow path of a foil strip through the dispenser.
- the cutter and folder may be positioned above the feed path of the foil, instead of below.
- the cutter and folder may translate e.g. using a linear actuator and a cam and follower arrangement instead of or in addition to rotation in different direction order to cut and fold respectively.
- the folder may be moved linearly instead of rotationally.
- the folder may be linearly moved toward the foil strip by a predetermined amount (e.g. to move the folder past the guide) to actuate folding. Movement of the folder linearly away from the foil strip may cause movement of one end of a pivoted link away from the foil strip, which in turn causes the other end of the pivoted link to move towards the foil strip. Movement of said other end of the pivoted link towards the foil strip may then actuate movement of the cutter towards the foil strip so as to actuate cutting.
- the folder has been actuated to cause cutting or folding, but in alternative embodiments the cutter or the cutter and folder may be actuated to cause cutting or folding.
