(3) FIGS. 2a-e illustrates views of one embodiment of the apparatus in accordance with the invention; and

(4) FIGS. 3a-c illustrate views of a further embodiment of the apparatus in accordance with the invention.

DETAILED DESCRIPTION OF THE INVENTION

(5) Referring firstly to FIG. 1, there is illustrated apparatus and a method in one embodiment for applying lines of resin to creases of a garment. The apparatus 2, includes a mounting means 4 with which are selectively located in respective support assemblies, first and second cartridges 6,8. The cartridges are selectively connectable to the mounting means so as to allow the replacement of the same when they become empty of the resin material which is provided in a fluid condition within a cavity of the cartridge.

(6) The cartridges can be as defined in the Applicant's patent EP1185379 and typically comprise a body 10 which defines therein a cavity in which a quantity of the fluid resin is located along with a piston. The cartridge, at one end, includes a connection 16 to a pressurised fluid source 18 which typically is an air pump. At or adjacent to the opposing end of the cartridge, there is provided a dispensing assembly including a nozzle 22 which has a channel or port 23 therethrough which connects the cavity of the cartridge with an opening at the tip of the port to allow a quantity of the resin material to flow through the said opening.

(7) The assembly is provided to be used in the application of resin from the respective cartridges 6,8 so that a first line of resin is applied from the first cartridge 6 and a second line of resin is applied from the second cartridge 8 with the lines of resin in parallel and along the base of parallel crease lines 30, 30′ in one or more garments 26, such as legs 26,26′ of a pair of trousers which are located on one or more support surfaces 32, 32′. The support surfaces have formed therein first and second grooves 28, 28′ which are provided at the same spaced apart relationship as are the openings from the respective cartridges when held in the mounting means 4 so that when the creases 30,30′ are in location along the respective grooves 28,28′ then the lines of resin are applied along the base of the respective creases and subsequently cure and harden to retain the crease line.

(8) The mounting means 4 can include some resilience as illustrated in FIG. 2d in terms of allowing sideways movement of the respective cartridges as indicated by arrows 34,34′ with respect to their longitudinal axis 52, 52′ so that any deviation in the crease line or groove along which the cartridges are moved, can be taken into account to thereby try to ensure that the line of resin is applied along the bases of the creases when in location along the grooves rather than a sidewall of the crease as this can adversely affect the quality of the resin application.

(9) The resin is moved out of the cartridge cavity through the opening 23 under the influence of the piston located in the cavity and the piston is moved by the provision of the pressurised air into the cavity to one side of the piston, with the resin material being located on the other side of the piston. Thus, the appropriate pressure of the pressurised air source allows the resin to be forced out of the cartridge, and the movement of the cartridge along the crease line allows the resin material to be applied from the opening onto the crease at the required amount and, this can occur simultaneously from both cartridges so as to allow two lines of resin to be applied at the same time.

(10) In the present invention, the operation of the pump 18 to allow the pressurised air to be provided, is achieved by the operator using their hand and, typically the same hand which is used to move the mounting means along the crease lines, by holding a gripping portion 40 located on the body 42 of the mounting means. Thus, the portion 40 is shaped so as to be ergonomically effective when gripped and allow the mounting means 4 to be moved to slide the cartridges along the crease lines. There is a significant advantage in terms of efficiency, comfort and usage of available space, in being able to use the gripping portion 40 to allow the operation of the pressurised fluid source and, at the same time, the movement of the mounting means and dual cartridges.

(11) In accordance with the embodiment shown in FIGS. 2a-e, to operate the fluid source 18 the operator holds the gripping portion 40 and applies a force to the same, typically downwardly towards the body 42 of the mounting means 4 as illustrated by arrow 44, and this acts to operate an air or electrical switching means 48 which is located in the mounting means, typically located between the portion 40 and the body 42. The movement of the gripping portion to operate the switching means 48, is typically guided by guide means 46 which allow smooth movement of the portion 40 so that the application of the movement force downwardly on the portion 40 and the movement of the same with respect to the mounting means, downwardly and upwardly, does not adversely affect the position of the gripping portion and hence the mounting means when it is being held to move the mounting means along the crease lines and so does not have any adverse effect on the guidance of the application of the resin onto the garment crease line or lines.

(12) In one embodiment, the switching means 48 includes a body and switch portion which is resiliently biased to a raised position away from the body 40 in which case the switching means is in an off position and the pressurised fluid supply is closed with the pump 18 not operating. The switching means 48 is positioned so that the application of the downward force 44 via the portion 40, acts against the biasing force and moves the switch portion to an on position which in turn sends an operate signal to operate the pump 18 via a connection cable or wirelessly to then allow the pressurised fluid to be provided from the pump to each of the cartridges and it will typically be the case that the same pump is used to supply the pressurised fluid to both cartridges 6,8.

(13) Turning to FIGS. 3a-c there is illustrated a further embodiment of mounting means 4 in accordance with the invention. In this embodiment the mounting means again includes a body 42 and a gripping portion 40 on a first upper surface 60 and support assemblies 50 including brackets 12,14 and resilient connectors 74 to the opposing surface 62 of the body 42 and which receive the cartridges therein. In this embodiment the gripping portion 40 is formed as an integral part of the body 42 and is fixed in position with respect thereto. However the operation of the pressurised fluid source in this embodiment is achieved by operating the switch portion 64 of the switching means 48. The switching means 48 are located with respect to the gripping means 40 and body 42 such that the switch portion 64 is accessible externally of the gripping means with the remainder of the switching means 48 located within the gripping portion 42 as shown in broken lines in FIGS. 3a and b.

(14) Typically the gripping means includes two access apertures 66, 68 and the switching means 48, in the embodiment shown in FIG. 3a is located so that the switch portion 64 is accessible through the aperture 66 and in FIG. 3b the switching means 48 is located so that the switch portion 64 is accessible through the aperture 68. As it is envisaged that the switch portion will be operated by the operator's thumb when holding the gripping portion 40 to move the mounting means, the ability to select which side of the gripping portion 40 at which the switch portion 64 is located, means that the apparatus can be easily adapted to allow convenient use of the switching means 48 by a right or left handed person when holding the gripping means 40 by sliding the switch portion 64 between on and off positions as indicated by arrows 70 in FIG. 3c and hence control the operation of the pump connected thereto.

(15) Typically, each of the said cartridges 6, 8 are located on first and second support assemblies 50 which include a bracket 12,14 and resilient connectors 74 which are provided at spaced locations along the longitudinal axis 52, 52′ of said cartridge so that the cartridges 6,8 are located and retained in a substantially parallel arrangement as illustrated in FIGS. 1 and 2a-e.

(16) There is therefore provided an improved form of cartridge mounting means and also an improved manner of control of operation of the application of the resin material from the cartridges held by the mounting means onto the crease lines of the garment. The improved control system for the supply of pressurised air also means that the bulkiness of the apparatus is also significantly reduced thereby allowing the apparatus to be used in relatively confined spaces whilst ensuring that the supply of the resin material along the crease lines is effectively achieved.
