Abstract

A carrier (1) is provided, adapted for use with a pouch (10) for a laminator, wherein the carrier comprises a layer of material (2) which is sufficiently rigid to provide a support for at least a part of the pouch to prevent bending of the part of the pouch. In use, the carrier and pouch are inserted together into a laminator, and pass between rollers of the laminator. As the carrier provides a support for at least a part of the pouch, when the carrier and the pouch are passed between the rollers, the carrier prevents the part of the pouch from bending and thus from wrapping around at least one of the rollers, which otherwise might cause the laminator to jam. As the carrier comprises one layer of material, when the carrier and the pouch are passed between heated rollers of the laminator, heat is directly transferred from one of the rollers to the pouch. This has advantages in the ease of lamination of an item (15) within the pouch. The pouch (10) may comprise A4 size sheets (11,12).

Description

PATENTS ACT 1977 Al 1243GB Title: Carriers for use with Laminator Pouches
Description of Invention
S The invention relates to carriers for use with laminator pouches.
Laminators have been used for some time to laminate various items such as paper products etc. Conventionally, an item is laminated by enclosing it between two sheets of laminating material, such as a plastics material, and sealing it therebetween, e.g. using an adhesive provided on the laminating material. Presently, to achieve this, the item is placed within a pouch comprising two sheets of laminating material, and the pouch is fed between rollers of a laminator. These act to simultaneously apply heat and pressure directly to the pouch, and thereby seal the laminating material around the item.
Such a method is satisfactory if the item to be laminated and the pouch are of a comparable size, e.g. A4 or AS size. However, if the item is smaller than the pouch, for example if an A4 size pouch is used with an approximately AS size item, then problems can arise. A part of the pouch will be empty, and this can become wrapped around one of the rollers of the laminator, causing it to jam.
Repair of the laminator is then necessary, at a cost to the owner or supplier.
According to the invention there is provided a carrier, adapted for use with a pouch for a laminator, wherein the carrier comprises a layer of material which is sufficiently rigid to provide a support for at least a part of the pouch to substantially prevent bending of the part of the pouch.
In use, the carrier and pouch are inserted together into a laminator, and pass between rollers of the laminator. As the carrier provides a support for at least a part of the pouch, when the carrier and the pouch are passed between the rollers, the carrier substantially prevents the part of the pouch from bending and thus from wrapping around at least one of the rollers, which otherwise might cause the laminator to jam. As the carrier comprises one layer of material, when the carrier and the pouch are passed between heated rollers of the laminator, heat is directly transferred from one of the rollers to the pouch. This has advantages in the ease of lamination of an item within the pouch.
The carrier may be sufficiently rigid to able to support its own weight and the weight of the part of the pouch thus substantially preventing bending of the part of the pouch.
The carrier may provide a support for a substantial part of the pouch.
The carrier may provide a support for all of the pouch. The carrier may provide support for an empty portion of the pouch which does not contain an item to be laminated. Additionally, the carrier may provide support for a portion of the pouch which contains an item to be laminated. The item to be laminated may be sufficiently rigid to substantially prevent bending of the portion of the pouch containing the item. However, the empty portion of the pouch may be able to bend. Using the carrier to provide a support for at least the empty portion of the pouch, the pouch may be used to laminate an item which is smaller than the size of the pouch, without the empty portion of the pouch bending and wrapping around one of the rollers of the laminator.
The carrier may provide a support for at least a part of the pouch such that one or more items to be laminated may be placed within the pouch without substantial bending of the part of the pouch. The carrier may provide a support for at least a part of the pouch such that the or each item may be substantially retained in the position in which they are placed. Thus, using the carrier, items may be more easily placed within the pouch and retained substantially in their position, whilst the pouch and the carrier are rnanoeuvred for insertion into a laminator, and whilst the pouch and the carrier pass through the laminator. The items are less likely to fall out of the pouch when the carrier is used.
The carrier may comprise any form which is able to provide a support to at least a part of the pouch. The carrier may comprise a sheet of material. The carrier may comprise a frame. The carrier may comprise a lattice.
The carrier may be of a size to provide a support for all of the pouch.
For example, if the pouch is A4 size, the carrier may be larger than A4 size.
For example, the carrier may be approximately 223mm wide and 310mm long.
If the pouch is AS size, the carrier may be larger than A5 size. The carrier may be approximately 0.26mm thick.
The carrier may comprise at least one retaining member to retain a portion of the pouch between the retaining member and the carrier. The retaining member may substantially prevent bending of the portion of the pouch. The portion of the pouch may then be prevented from wrapping around the rollers of the laminator. The carrier may comprise at least one retaining member to retain at least a part of an edge of the pouch between the retaining member and the carrier. For example, the carrier may comprise a retaining member in the form of a lip. For example, the carrier may comprise a retaining member in the form of a tab at a first corner portion of the edge of the pouch, and a retaining member in the form of a tab at a second corner portion of the edge of the pouch. The edge of the pouch may be a leading edge of the pouch, i.e. the edge which is first inserted into a laminator, and/or a trailing edge of the pouch, i.e. the edge which is last inserted into a laminator.
The carrier may be made of a cardboard material. The carrier may be made of a heat conducting material. The carrier may be made of a non-stick material, such as Teflon (RTM) or a silicon material. The carrier may be coated with a non stick material. The carrier may be coated on one side with a non stick material, on which side the pouch may be positioned for use. If adhesive leaks from the pouch on to the side of the carrier, this may be more easily wiped off The carrier may then be more easily used more than once.
The carrier may be made of an anti static material. The carrier may he coated with an anti static material. The carrier may be coated on one side with an anti static material, on which side the pouch may be positioned for use. This allows easier positioning of the pouch on the side of the carrier.
The carrier and the pouch may be positioned together for use. The pouch may be placed on the carrier for use. The carrier and pouch may be inserted into a laminator in a substantially horizontal position, with the pouch uppermost. The pouch may be attached to the carrier for use. The carrier and pouch may be inserted into a laminator in a substantially horizontal position, with the pouch lowermost.
The carrier may be used with various types of laminators, for example, fixed temperature larninators.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which Figure 1 is a schematic perspective representation of a carrier according to the invention, Figure 2 is a schematic perspective representation of a pouch for use with the carrier of Figure 1, Figure 3 is a schematic perspective representation of the carrier of Figure 1 and the pouch of Figure 2 in position for use, and Figure 4 is a schematic side representation of the carrier and pouch of Figure 3, and a laminator.
Referring to Figure 1, the carrier 1 comprises a substantially rectangular sheet of material 2, which is approximately 223mm wide, approximately 310mm long, and approximately 0.26mm thick. The material of the carrier is a cardboard material, and is sufficiently rigid to be able to support its own weight, without significant bending, e.g. under the force of gravity. A surface 3 of the carrier is coated with a non stick and anti static material. The surface 3 is provided with a retaining member 4, which is in the form of a substantially rectangular lip. This is attached to the surface 3, for example by adhesive, along three sides 5 thereof The fourth side 6 of the retaining member is not attached to the surface 3 of the carrier, and the retaining member 4 may be lifted away from the surface 3 at this side, for insertion of part of a pouch between the surface 3 and the retaining member 4.
Referring to Figure 2, the pouch 10 comprises two sheets of laminating material, 11, 12. Each sheet of the pouch is approximately A4 size, i.e. approximately 210mm wide and approximately 297mm long. The laminating material of each sheet is a plastics material, and is flimsy, i.e. it cannot support its own weight without significant bending. The sheets of laminating material 11, 12 are attached together at a sealed edge 13 only. The sheets may therefore be separated, as shown, and an item to be laminated placed between them.
Inner surfaces 14 of the sheets, i.e. the surfaces of the sheets which face each other, are provided with adhesive. Thus during the lamination process, the sheets will adhere to the item being laminated and to each other. It will be appreciated that the item to be laminated should be wholly contained between the two sheets 11, 12 of the pouch 10. However, apart from this criterion, the item may be just a little smaller than the pouch, or significantly smaller than he pouch. In the Figure, an item 15 which is significantly smaller than the pouch is shown. This is inserted between the sheets of laminating material 11, 12, such that a portion thereof abuts the sealed edge 13, and the sheets of laminating material are then brought together. This leaves a portion 16 of the pouch which is empty. If the item 15 is sufficiently rigid, it will be able to support its own weight and that of the laminating sheets of the pouch around it, without significant bending. However, the empty portion 16 of the pouch will not be able to support its own weight, and will bend easily.
Referring to Figure 3, the carrier 1 and the pouch 10 are shown in a position for use. The carrier 1 is placed in a substantially horizontal position, with the surface 3 uppermost. The pouch 10 is then placed on the surface 3 of the carrier, and the sealed edge 13 of the pouch is inserted between the retaining member 4 and the surface 3 of the carrier. The pouch 10 is thus positioned substantially centrally on the carrier 1, as shown. The anti static / coating on the surface 3 of the carrier assists in the positioning of the pouch 10 on the surface. The cardboard material of the carrier 1 is sufficiently rigid to support its own weight and also that of the pouch 10, and the carrier is therefore able to provide a support for the pouch and to substantially prevent bending of the pouch. As the carrier 1 is wider and longer than the pouch 10, the carrier provides a support for all parts of the pouch, including the portion which contains the item 15 and the portion 16 which is empty.
Referring to Figure 4, a side view of the carrier 1 and the pouch 10 is shown. To laminate the item 15, the carrier 1 and the pouch 10, containing the item 15, are inserted together into a laminator 20. The carrier 1 and the pouch enter the laminator 20 via an entrance opening, and are fed through the laminator 20, in the direction of the arrow A, by rollers 22, 23, exiting the laminator via an exit opening. The rollers 22, 23 simultaneously apply heat and pressure to the carrier and the pouch, and the sheets of the laminating material of the pouch are sealed by the adhesive thereon around the item 15. As the carrier 1 provides a support for the whole of the pouch 10, especially the empty portion 16, the pouch is substantially prevented from bending e.g. under gravity, and thus it cannot become wrapped around the lower roller 23. As the leading edge of the pouch 10, which comprises the sealed edge 13 thereof, is positioned under the retaining member 4 of the carrier, this edge of the pouch cannot bend upwards and is prevented from wrapping around the upper roller 22. Thus use of the carrier allows a pouch to be used to laminate an item which is significantly smaller than the pouch, without problems of jamming the laminator. During the lamination process, the roller 22 applies pressure and heat directly to the pouch 1 0, but the roller 23 applies pressure and heat to the pouch 10 via the carrier 1. The roller 23 may require to apply more heat than if the carrier were not used, but this may be alleviated by making the carrier of a heat conducting material. The carrier provide a support for all of the pouch such the item to be laminated may be placed within the pouch without substantial bending of the part of the pouch, and the item may be substantially retained in the position in which it is placed. Thus, using the carrier, items may be more easily placed within the pouch and retained substantially in their position, whilst the pouch and the carrier are rnanoeuvred for insertion into a laminator, and whilst the pouch and the carrier pass through the laminator. The items are less likely to fall out of the pouch when the carrier is used.
The above description has been limited to a pouch of approximately A4 size, and a carrier which is larger than A4 size. However, it will be appreciated, that the invention of the carrier can be used with any sized pouch, e.g. A5 size. It will also be appreciated that the form of the carrier is not limited to a sheet, but could comprise a frame or a lattice or any form capable of providing a support for the pouch.
When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
