Apparatus for the application of material to a crease of a garment

An apparatus for the application of resin material along crease line of one or more garments simultaneously by providing means which allow at least first and second cartridges containing the resin material to be mounted in a spaced relationship so as to allow resin from each of the cartridges to be dispensed simultaneously. The resin can be applied in substantially less time than conventional systems which only use one cartridge at a time.

CROSS-REFERENCE TO RELATED APPLICATIONS

This United States application is the National Phase of PCT Application No. PCT/GB2018/051482 filed 31 May 2018, which claims priority to British Patent Application No. 1708640.6 filed 31 May 2017, each of which is incorporated herein by reference.

The invention to which this application relates is apparatus of a form which can be used to apply a material to a garment and, in particular, to allow a ribbon or thin line of the material to be applied along a crease line formed in the garment. The material is typically a resin type material which is applied in a liquid form but which, when set, has a rigidity so as to help maintain the shape of the crease in the garment during use of the same.

The provision of a resin material along crease lines of a garment in order to maintain the crease and improve the appearance of the garment during use, is well known, and the applicant in their granted patents EP1405678 and EP1185379, disclose one form of apparatus. This, and other, form of apparatus are used extensively throughout the world and most typically used at the time of manufacturing the garment and/or following laundry of the garment.

It will be appreciated that each application of material from the cartridge in which the resin is held, takes time and, the cartridge, the apparatus in which the cartridge is located, the resin material which is dispensed and the operator time, all add to the cost of production of the garment and hence there is always pressure to be able to reduce the cost of the consumables, the apparatus and the operator time so as to reduce the impact on the overall cost of the garment whilst, and importantly, maintaining the benefits of prolonging the crease life by use of the apparatus and resin material as this is regarded as being a significant advantage in the sale of one form of garment with the resin material applied in comparison to another garment without the resin material applied to the crease lines.

An aim of the present invention is therefore to provide a means to allow the resin material to be applied in a more economic and time efficient manner whilst, at the same time, ensuring that the accuracy and beneficial effect of the application of the material is at least maintained and preferably improved.

In a first aspect of the invention, there is provided apparatus for the application of a fluid material along one or more crease lines formed in one or more garments, said apparatus including at least first and second cartridges in each of which a quantity of the said fluid material is held so as to be dispensed therefrom through an aperture and wherein at least during dispensing of the fluid material the cartridges are located on mounting means and spaced apart with their longitudinal axes substantially parallel.

In one embodiment the fluid material is dispensed during relative movement between the apparatus and the garment.

In one embodiment the relative movement between the cartridges and/or at least part of the mounting means is possible.

In one embodiment the relative movement between the cartridges and/or mounting means is within a predetermined range. In one embodiment the relative movement is linear inasmuch that the angle between the nozzle and the surface of the garment is substantially maintained. In one embodiment the angle is in the range of 80 to 100° and preferably substantially 90°.

In addition or alternatively the relative movement includes a degree of rotatable movement about an axis which is substantially parallel with the direction of movement of the cartridge and/or garment during the application of the fluid therefrom along the crease line.

Typically the garment is located on a support surface which is substantially flat save for the provision of a substantially V-shaped groove for the location of each garment crease line to which the fluid is to be applied at the same time.

In this embodiment typically the support surface will include a plurality of spaced, substantially parallel V-shaped grooves. Typically the spacing is substantially the same as the spacing between the cartridges.

Typically each of said cartridges is provided to be movable within a range of movement with respect to at least part of the mounting means and/or each other.

Typically each cartridge is independently movable.

Typically the cartridges are each linearly movable towards and away from each other within a predefined movement range. Typically during the movement the cartridges are maintained substantially parallel and with their respective nozzles substantially perpendicular to the surface of the support on which the garment is located.

In one embodiment, the cartridge is provided integrally with, or inserted into location with, the mounting means which then maintain the cartridges in a spaced parallel relationship.

In one embodiment, each of the cartridge nozzles is located with respect to a garment crease line so as to allow the simultaneous dispensation of material therefrom along the respective crease lines.

Typically the cartridge nozzles are located with respect to the crease lines such that the dispensed material is applied along the base of the respective crease lines rather than to one side of the crease line. This is achieved by allowing the movement of the cartridges with respect to the mounting means in order to take into account any deviation in the V-shaped grooves in the support surface whilst maintaining the outlet from the nozzle in position at the base of the crease.

In one embodiment, the mounting means includes resilient means which allow relative movement of the cartridges so as to maintain the nozzles in a position so as to dispense the material along the crease lines base Typically the resilient means are such as to allow the movement of the cartridge with respect to the mounting means so as to take into account any deviation in the crease line and/or between respective crease lines and thereby maintain the dispensation of the material along the base of the respective crease lines.

Typically the biasing means (most typically in the form of springs) are provided so as to allow the movement of the cartridge but when the movement force is removed, the resilience of the biasing means urge the cartridges back to a default position.

In one embodiment, the nozzles are provided as integral parts of the cartridge or alternatively, are inserted or attached to the cartridge. Typically location means are provided so as to maintain the nozzle in a non-rotatable position with respect to the cartridge at least one the cartridge and nozzle are in use. This acts to ensure that the nozzle is maintained in the required orientation with respect to the cartridge.

In one embodiment, the outlet from the nozzle is linear and the longitudinal axis of the said outlet is parallel with the crease to which the fluid material is applied.

In one embodiment the movement of the cartridge with respect to part of the mounting means is achieved by providing a sufficient space so as to allow movement of the cartridge within a range of movement defined by sidewalls of a slot of the mounting means in which at least the nozzle and/or fin of the cartridge is located.

In another embodiment the movement of the cartridge with respect to part of the mounting means is achieved by providing a first mounting means part which receives the cartridge in a substantially fixed position and said mounting means part is mounted with respect to a further part of the mounting means and is axially movable with respect thereto with respect to an axis that is offset to, and substantially parallel with the longitudinal axis of the cartridge.

In one embodiment the first part of the mounting means is provide with an arm which is received in a recess in the second part of the mounting means.

Typically the same connection is used for each of the cartridges provided on the mounting means.

In an alternative embodiment, biasing means are provided within the mounting means to allow the movement of the legs linearly within a predetermined range in at least one direction substantially perpendicular to the longitudinal axis of the cartridge and the biasing means act, once a movement force is removed or reduced from the cartridge, to return the cartridge to a default position.

Thus, in whichever embodiment the cartridges and in particular the nozzle can move within a predetermined range of movement to take into account deviation in the crease line or in the surface underlying the crease and at the same time, once the deviation is passed or other movement force is removed, the nozzles will return to respective default locations with respect to the mounting means and the crease lines.

In a further aspect of the invention, there is provided apparatus for the application of a fluid material along crease lines of one or more garments, said apparatus including mounting means for locating at least first and second cartridges in which quantities of the fluid material is held and dispensed therefrom via respective nozzles during relative movement between the apparatus and the garment and wherein the said cartridges are provided so as to simultaneously dispense the said fluid material along first and second crease lines.

In one embodiment the first and second crease lines are spaced apart on the garment by a distance which is substantially the same as the distance of the spacing between the respective longitudinal axes of the first and second cartridges.

In one embodiment the mounting means include a first portion locating the cartridges at or towards one end and a second portion locating the cartridges at or towards the opposing end.

In one embodiment the first and/or second portions of the mounting means include springs mounted therein to allow movement of the cartridges with respect to each other, whilst biasing the same to a default position in which the same are substantially parallel.

In a further aspect of the invention there is provided apparatus for the dispensing of a fluid along one or more crease lines in ne one more garments, said apparatus including two or more cartridges, each cartridge including a quantity of the aid fluid therein and said fluid is dispensed from the cartridges via an aperture by the provision of a pressurised fluid source onto a nozzle located to be moved by the pressurised fluid along the interior of the cartridge so as to move the fluid towards the said aperture to be dispensed, a supply of said pressurised fluid is attached to each cartridge and control means are provided to allow the user selection of the supply of said pressurised fluid to the cartridges, a support base having spaced apart grooves for the rescript there along of the crease lines to which the fluid is to be dispensed and wherein mounting means are provided to allow the two or more cartridges to be located in a spaced apart relationship, with a spacing substantially equal to the spacing between said spaced apart grooves and relative movement between the mounting means with the cartridges located therein and the support base a lows the fluid being dispensed from the said cartridges to be dispensed along the said crease lines.

In one embodiment the control means for the pressurised fluid is provided with a user actuation means which is located on or adjacent to the mounting means so as to be operable by the user when gripping the mounting means.

Referring firstly toFIGs. 1andb, there is illustrated a garment2such as a pair of trousers, which have crease lines4formed therein. The crease lines4are shown in position on a support surface6and it is shown that the crease lines4are located in respective grooves8which may be V or gull wing shaped in sections8which run substantially parallel along the support surface. With the crease lines4in position, then in accordance with the invention, respective cartridges10in which the fluid resin material is held can be used to deposit, from an aperture in their respective nozzles14, a ribbon12of the fluid material therefrom, along the length of the crease line, with the aim being to ensure that the ribbon of resin which is dispensed is dispensed into the base of each crease line as there is relative movement between the cartridges and the garments. In this embodiment the cartridges10and mounting means22therefore are moved as indicated by arrow24such that the nozzles14move along the crease lines4Once applied, the resin then cures and serves to maintain the crease line in the garment for a longer period of time than if the resin was not present and thereby maintaining the appearance of the garment.

FIG. 2illustrates a cartridge10of a type which is suitable for use in accordance with the invention and the cartridge comprises a body18which has a cavity therein and in which the fluid resin is held. At one end20of the cartridge there is provided a connection for a pressurised gas connection which causes movement of a piston28in the cavity in the direction of arrow30so as to cause the movement of the resin towards the opposing end32at which there is provided a tongue34with nozzle14secured therein. A bore passes through the tongue and hence into a bore in the nozzle which in turn leads to an elongate aperture in the nozzle which allows the ribbon of resin to be applied from the cartridge10. The cartridge, or mounting means therefore, can also include guide means in the form of fins36which are aligned with the outlet of the nozzle along the longitudinal axis38of the cartridge so that these are moved along the crease line and groove in advance of the nozzle with respect to the direction of movement so as to further assist in ensuring that the ribbon of the material is applied into the base of the crease line4during the relative movement between the garment and the cartridge to apply the resin material.

The cartridges10are typically provided as a disposable item such that once the resin therein has been used, the cartridge can be disposed or alternatively, the cartridge could be provided to be refilled. In either case, it is desired that the cartridge can be removed from the apparatus for disposal and replacement, or refilling.

In accordance with the invention, the apparatus further includes a mounting means22which, in this embodiment includes receiving locations for two cartridges10and allows the first and second cartridges to be located with their respective longitudinal axes38substantially parallel to each other and spaced apart by a predetermined distance X The distance of separation will typically be that of a space in between the two grooves8in the work surface6so as to allow the resin material to be applied from the said first and second cartridges10simultaneously along the two crease lines4,4′ each respectively located in a groove8. It will therefore be appreciated that this will allow the application of the resin material from two cartridges and hence at a much faster rate than by using one cartridge, although it should be appreciated that the mounting arrangement which is now described for the cartridges can be effective and provide advantage in the mounting of only one cartridge. In order to allow the use of the two cartridges10, it is important that the same are held in a parallel relationship and that this parallel relationship can be ensured each time the respective cartridges are placed into the mounting means.

In addition, it is important that the cartridges10are movable within a predetermined range of movement in order to allow variations in the location of the creases4and/or the grooves8to be taken into account and ensure that the resin material line follows the base of the crease4as, if this is not achieved then the resin material would be applied to one side of the crease which would not be as effective in extending the lifetime of the crease. In accordance with the invention, this is achieved by providing a degree of cartridge movement in the mounting means22to allow relative movement between the cartridges and/or between the cartridge and the mounting means and thereby allow relative movement of the cartridges whilst ensuring that the same are encouraged to move back to the predetermined spacing X.

InFIGS. 3a-cone embodiment of the mounting means22is shown and it can be seen that the mounting means comprise a first part40, a further part42for connection with cartridge10and a further part42′ for connection with cartridge10′. InFIG. 3b, cartridge10is removed for ease of illustration and inFIG. 4cpart of the first part40of the mounting means is shown in cross section along line A-A.

The parts42,42′ are provided with a receiving housing44into which the end32of the cartridge is located and the tongue34is inserted along a slot46in the housing. The part42,42′ also includes a shaped arm48which is received in a shaped recess50in the part40of the mounting means22. The arm48and recess are shaped so as to allow relative movement about a pivot axis52which is typically in line with the axis38of the cartridge and the relative movement is rotational movement as indicated by arrows56,58with the range of movement defined by the contact between the arm48and the sidewalls54of the recess.

An alternative embodiment is illustrated inFIGS. 4a-cwherein there is shown a mounting means22which includes therein receiving housings62,62′ which are provided to receive the end32of the cartridges10.10′ therein. InFIG. 4b, cartridge10is removed for ease of illustration and inFIG. 4cpart of the first part40of the mounting means is shown in cross section along line B-B. The tongue34of each cartridge is received in a slot60,60′ and it is the degree of movement between the walls64of the slot60and the walls66of the tongue34which define the possible range of movement in the directions of arrows68,70about the axes38of the cartridges10,10′.

A third embodiment is illustrated inFIGS. 5aandb. In this case the mounting means22is shown to comprise two portions72,74, although it should be appreciated that it would still be possible to use only one portion as in the other embodiments.

The first portion72is mounted at the tongue34,34′ end76, of the cartridges10,10′ and the second portion74is mounted at the inlet end78of the cartridges10,10′ so as to retain the same in a substantially parallel relationship and with the nozzles14substantially perpendicular to the support surface and garment thereon. In this relationship it can be ensured that the outlets from the respective cartridge nozzles lie in and are moved along the base of the respective crease lines so as to move accurately and effectively apply the fluid into the base of the crease as the cartridges are moved along the respective crease lines of the garment.

On occasion, the grooves8in the support surface in which the crease lines lie may deviate from straight and parallel due to inconsistencies when manufacturing the same and/or due to wear and/or due to warping of the support surface. In this embodiment, in order to allow the nozzles14,14′ of the cartridges10,10′ to follow the base of the groove8and hence the crease line lying therein, the cartridges10.10′ are movable linearly with respect to the mounting means body within a predefined range of movement. The movement is linear as indicated by the arrows80and are along axes82,84which are substantially perpendicular to the longitudinal axes38,38′ of the cartridges10,10′. The movement is achieved and controlled in this embodiment by providing telescopic sections86in each of the portions72,74between the cartridges10,10′.

In order to ensure that when the cause for movement of the cartridges has been removed the cartridges return to the default position, the portions72,74include springs88which can be overcome by the movement force exerted on the nozzles, and in turn the cartridge, by the deviation of the grooves8as the guide fins36follow the same as the cartridges are moved along the respective crease lines and grooves to apply the fluid. However the springs are sufficiently strong such that when the movement force is removed the springs exert a force so as to move the cartridges10,10′ back into the default positions with the required spacing.

Referring now toFIGS. 6a-fthere is illustrated a further embodiment of mounting means102in accordance with one embodiment of the invention.

Once again, the mounting means102include a body104and, located with the body, are first holding means106and second holding means108. Each of the holding means is provided to receive a cartridge110,112therein and to thereby position the respective cartridges with regard to the body.

Typically, the spacing X between the cartridges and in particular, the nozzles of with dispensing apertures114116of the cartridges, when located in the holding means, is substantially the same as the spacing between the respective garment crease lines when located in the grooves8in the work surface and thereby allow the resin to be simultaneously dispensed from the respective cartridges through the aperture in the nozzles and along the base of the crease lines. In one embodiment the spacing X is 55 mm. In one embodiment the spacing between the cartridges is adjustable to allow the same to be altered to react to being used with support surfaces which have grooves with a different spacing between the same. Typically once the adjustment has been made the spacing is locked so as to prevent further alteration during the use of the mounting means with the particular work surface.

The guidance of the movement of the mounting means and hence cartridges110,112along the crease lines, is again achieved by the provision of guide fins120on each of the cartridges which are located such that when the cartridges are moved with the mounting means, the guide fins are in advance of the dispensing nozzle and can therefore be moved along the crease and hence grooves in advance of the resin which is being dispensed from the cartridge nozzle.

Thus, in accordance with the invention, the mounting means as shown, allow the simultaneous dispensation of resin from the two cartridges110,112in a controlled manner.

The body104also includes a handle portion122which is located on a surface124of the body opposing that to which the holding means are located. The handle is provided with a head portion126which is provided to be gripped by the user in order to move the body, mounting means and cartridges as an integral unit. The handle can be of any desired form but it is believed that the shape as shown is particularly advantageous in being comfortable to be gripped whilst at the same time, ensuring that a secure grip can be achieved to move the mounting means and cartridges in a controlled manner. The head portion126, in this embodiment, is rotatable about an axis128so as to aid in the continued straight line movement of the body by the user as the distance of the body and angular orientation of the same from the user changes and therefore maintains a straight line of movement along the groove and avoids the possibility of the movement of the mounting means being along a bend as the user. The rotation of the head portion126allows the user to continue to grip it in the same way and move the mounting means in a straight line whilst the relative position of their hand with respect to the body104changes.

In one embodiment, the body and/or handle may also include a control switch130for user actuation to allow the switching on and off of the pressurised fluid source which is directed to both of the cartridges106,108in order to move the pistons which are located within the respective cartridges towards the dispensing nozzles and hence move the resin which is to be dispensed towards the nozzle under pressure to ensure that the resin is emitted from the nozzle aperture in a continuous manner. In the embodiment shown the switch130is located on the head portion to be selectively moved. In another embodiment the head portion may be the switch and can be activated by selectively moving the same to different positions along the axis128to activate a microswitch located in the body of the mounting means.

Typically the pressurised are source includes a regulator to allow equal gas, typically pressurised air flow into the respective cartridges. This and/or manual adjustment allows the air supply to be adapted to suit different potential flow rates of the fluid material in particular cartridges and/or to take into account variation in environmental conditions which may affect the flow rate of the fluid.

Typically, the holding means and/or handle are located with the body in a manner to allow limited movement of the same with respect to the body104so as to take into account any variation in movement of the cartridge as it is moved along the crease line whilst, at the same time, ensuring that the resin is still applied into the crease rather than to a side of the same.

FIG. 7illustrates the mounting means ofFIGS. 6a-fwith the top part of the body104removed for ease of illustration and it is shown the manner in which, for each of the cartridges106,108, there are provided first and second supports202,204and202′,204′ respectively. Each of the supports has a channel in which there is provided a bearing206. In turn, the bearing has an aperture which receives therein a shaft208and the shaft extends along the width of the body104. Each shaft208is received in end supports210at opposing ends of the same which therefore retain the shaft in position with respect to the body. Spaced inwardly of the same, there are provided stops212which are sized so as to allow the shaft to pass there through but to prevent the carrier204of the cartridge from passing there through. This therefore means that the range of movement in the direction of arrows210212, is restricted by the stops whilst, at the time, the gap between the stops212and the end face204of the carrier, allow a limited scope of movement and hence a limited scope of limited movement of the cartridge attached to the carrier204. Thus, in accordance with the invention it will be seen that the relative spacing between the cartridges is adjustable as cartridges are moved in the direction214along the respective crease lines in the garment a and grooves8in the work surface. Once again springs, not shown, can be provided to act, in this case, between a stop212and the end surface of the adjacent carrier204,206,204′,206′, in order to bias the respective cartridge position to a default position.

The need to provide the possibility of movement between respective cartridges and/or a cartridge with respect to the body, is required in order to allow the nozzle through which the fluid material is dispensed from each cartridge, to remain in a plane which is substantially perpendicular to the longitudinal axis of the body of the mounting means. The mounting means body, in turn, is provided to be substantially parallel with the work surface in which the grooves8are provided and upon which the garment to which the fluid material is to be applied, is located. This, in turn, means that the fluid material is dispensed into the base of the crease lines of the garment and along the same to thereby ensure that the fluid material is located in the required position so as to act to maintain the crease in the garment. If the fluid material is not dispensed into the crease line but, instead, is applied onto the garment surface adjacent to the crease line then the fluid material does not act on the crease and therefore does not provide the required permanence of crease characteristic. Thus, if the linear movement between the cartridges and/or the cartridges and the body was not possible the line of application of the fluid can diverge from the line along which the crease follows the groove in the surface.

It will therefore be appreciated that in accordance with the invention, there is provided apparatus which allows the application of resin material along crease lines in substantially less time than the conventional systems which only use one cartridge at a time. In addition, the quality of application of the resin is maintained and it is ensured that the application of the resin is along the base of the crease as required.
