Description

METHOD AND APPARATUS FOR LAMINATING FOILS The present invention relates to a method and apparatus for laminating foils of plastics material.
It is known to provide a plastics foil having a decorative surface effect, such as woodgrain, coloured or marbled or any other effect, for usage in applying to furniture and the like. Such furniture, for example kitchen cabinet doors. may be provided with rebates and indentations to which the decorative foil must adhere. During the process of forming the foil into these irregularities, the decorative foil may become damaged. Damage is also possible during transportation and erection of the furniture.
It is an object of the present invention to provide a method and apparatus for laminating such decorative foils with a protective layer of film before they are applied to the furniture. The film should be so adhesive that it will remain in place until the furniture is finally in situ, when it can be removed easily and without damage to the decorative effect.
According to a first aspect of the present invention, there is provided an apparatus for laminating plastics foils comprising a first roller or mandrel means to accept a roll of surface decorated foil, a second roller or mandrel means for accepting a roll of protective adhesive coated plastics film, a pair of nip rollers to which the foil and film may be fed, means to drive at least one of said nip rollers at a predetermined speed, a third roller or mandrel means to accept a take-up roll of laminate, independent means to drive said third roll, and means to sense the tension in the web of laminate at its approach to the take-up roller and signal the independent drive mcans to drive said lakc-ul) roll it sucll a sl)ccd as to maintain the tension substantially constant.
The means to sense tension may sense the torque on the independent drive means.
At least one of the nip rollers may be coated with an anti-static resiliently deformable material.
The apparatus may further comprise at least one, preferably two, freely rotatable rolls over or under which the foil and/or the laminate pass, which roll or rolls are electrically earthed to reduce anti-static build up.
The independently driven drive may comprise a pneumatic motor driven at a predetermined pneumatic pressure to drive at a predetermined torque.
The foil having surface decoration may be of PVC or a like plastics material.
The protective film may be a polyetl0ylene film.
In this case, the polyethylene film may be pre-treated to have an adhesive surface on one face thereof, which surface may be optionally treated by corona discharge.
The adhesive material may be natural rubber, or an acrylic glue. which is preferably corona treated so as not to adhere to other layers of similar material on the roll.
The driven nip roller may drive at a speed between 0.4 metres per minute to 55 metres per minute. dependent on the foil substrate.
Each of the said rollers or mandrel means may be transversely trackable by up to 30 millimetres each side of a central position. optionally 25mm each side.
According to a second aspect of the present invention, there is provided a method of lamiiiniiiig plastics foils col0l)riNi iig with NIcI)N ol' providing l'irsl roll of stirIicc decorative plastics foil, providing a second roll of protective adhesive coated plastics film, providing a pair of nip rollers at least one of which is driven at a predetermined speed, passing said foil and said film between said pair of nip rollers to laminate them, providing a take up roller to accept the laminate, said take-up roller being independently driven, providing means to drive said take-up roller, providing means to sense the tension of the laminate web between the nip rollers and the take-up roller and signal said drive means to drive the take-up roller and maintain the tension substantially constant.
Preferably, said take up roller drive means is provided with a torque sensor and is thereby prevented from operating when the tension in the web exceeds the predetermined tension.
According to a third aspect of the invention there is provided a coil of laminated plastics material produced by the above method or using the above apparatus.
An embodiment of the present invention will now be more particularly described by way of example and with reference to the accompanying drawings. the single figure of which slows schematically an apparatus embodying tulle invention.
Referring now to the drawings there is shown schematically an apparatus embodying the invention. It includes a pair of nip rollers 1 and 2. of which the lowermost. in use, roller 1 is driven at a predetermined speed. Each of the rollers is coated with an anti-static rubber composition and the drive speed may vary between 0.4 metres per minute to 55 metres per minute. dependent on the substrate being laminated.
The substrate, which is usually a decorated PVC foil is fed from a coil at roller or mandrel 3 (or alternatively from change over roll or mandrel 4) to the nip between nip rollers 1 and 2 via a freely rotating chromium plated roller 5. the purpose of which is to reduce static electricity in the foil and help in the transverse tracking of the process.
Also fed to the nip between rollers 1 and 2 is a film of protective material, preferably transparent and preferably of polyethylene, which is stored on roll 6. This film may be coated with an adhesive sucls as rubber or an almlcrylic rcsin (() lc ;Idhcsivc oil Ile facc n0cciiig the PVC foil. The film is previously treated by corona discharge to render the film non adhesive to its own adjacent layer in the coil.
The laminated film then passes under a second chromium plated freely rotatable roller 7 on to a take up roller 8. The purpose of this second roller 7 is to reduce static electricity by itself being earthed and to help in the transverse tracking of the process. To this end, each of the rollers 3, 4, 6 and 8 are independently trackable in a transverse direction by up to 30mm, preferably 25 mm, each side of centre.
Take up roller 8 or the mandrel supporting the take-up roll is driven independently of the drive to nip roller 1 by a pneumatic motor. The speed of this motor is determined by the tension in portion 9 of the web of laminate to the effect that, as the tension increases, the motor slows down, and as the tension decreases, the motor speeds up. Hence, the completed coil of laminate at roller 8 will be evenly wound.
It is important that the speed of the apparatus is set by the nip rollers 1 and 2 since the variation in diameters of the feed rollers 3 and 6 and that of the take up roller 8 Will vary as the process continues. and moreover the difterential longtitudinal stretch of tlie materials of the PVC foil fed from roller 3 and the polyethylene film fed from roller 6 can cause disruptions and other surface imperfections if they were drawn through the nip under tension by the drive to roller 8.
The anti-static coating on rollers 1 and 7 and the anti-static earthing properties of rollers 5 and 7 ensure that the two layers of laminated material will bond more effectively.
The coil of laminated material may be used to coat furniture or other articles so that the decorated foil is protected throughout the process and during storage, transportation and installation. The protective film of polyethylene may then be removed once the finished articles of furniture are in place.
