Abstract

A process for the manufacture of a fiberglass, cultured marble or onyx products which comprises: a) Storing suitable moulds in a heated room at above 30?oC; b) Moving the mould to an area where Gelcote is applied using standard equipment; c) Moving the mould to an area for the application of the required patterns to the "gelcoted" surface by means of silk screens made to a predetermined design; d) Moving the mould to a mixing head area where components of the final products, comprising a resin mixture and catalyst, which are stored separately, are mixed and added to the mould to form the required article; e) The product mould complete with article is then moved to a demoulding and storage area and after allowing for a curing time of about 20 minutes, the article is removed from the mould; f) The mould is then returned to the heated room, in (a) above, to complete the process cycle.

Description

THE RO ERTS SYSTEM FOR THE MATTUPACTURE OF FIBERGLASS ,
CULTURED MARBLE & ONYX PRODUCTS .
DESCRIPTION
A system for the manufacture of fibreglass, cultured marble & onyx products.
TECHNICAL FIELD.
This invention is a system for the manufacture of fibreglass, culturea marble & onyx products for the building, decorative, novelty, leisure & other industries .
Bachground Art:
Fibreglass , cultured Barbie & onyx products are well known & ex t ensi vely used in the building,decprative ,novelty,leisure
& other industries for nany years.
In the building industry,these products include vanity tops
&. integral basins,wall panels, shower enclosures, baths & many other items.
Production of these items is sainly achieved by nixing a predetermined formula in a conventional doughc-iser, then hand pour the formula into buckets or other containers,manually add catalyst & other additives & stir same in these containers, add colouring & veining to provide color & pattern and then hand pour into a preselected mould and left to cure for some
25 minutes.The article is then removed from the mould.
DISCLOSURE:
The invention is ε system for the menufacture of fibreglass, cultured marble & onyx products,using mechanical methods for the continuous mixing of the formula,depositing the same to preheated moulds,which in turn have been gelcoted & with pattern & colour applied by means of silk screens.These methods allow for the reduction in curing tines used & so attain greater productivity over conventional methods,now in use.
DRAWINGS:
A drawing is enclosed which shows a typical layout of the areas to be used within the system and the movement, of the moulds throughout the nrocess. THE ROBERTS SYSTEM - DESCRIPTION (CONTINUED)
BEST MODE FOR CARRYING OUT THE INVENTION:
The following areas are required to attain the best results for the manufacture of fibrεglass,cultured marble & onyx products when using The Roberts System & these areas are further defined in the attached drawing:
(A) Heated room for mould storeage - suggested constant 30degrees Cent.
(B) Spray area for application of Gelcote to moulds.
(C) Silk screen area for application of the pattern & pigments to mould
Bulk container-blunderer-dispenser area for the storeage and nixing of un-catalysed resin,calcite & pignent in the proportions required by the designated fonzrαla. -2.
This container will be constructed from stainless steel or aluniniun cuter with stainless steel or aluminium nixing blades to the inner - such blades to be driven by an electric motor.libte,the capacity of the container and the electric motor will be dependant on the storeage requirements of the individual manufacturer. -3.
The formula will be mixed & paddled when the process is non operational.and will be pressurised to approximately 20 lbs/sq.foot. -4.
P.V.C.or similar feeder lines will be fitted from this container to the mixing head area (e) for application of the formula to the moulds.
(E) Mixing head area for the application of the formula from area (d) with catalyst from area (f),to the moulds.
(P) Catalyst storeage container fabricated from stainless steel or aluminium.The capacity of this container: will be dependant on the storeage requirements of the individual manufacturer.
(&) Demoulding & storeage area for finished products. BEST MODE FOR CAR RYING OUT THE I NVE TION - Continued .
PROCESS :
1. The moulds will be stored in the room area (a) at a constant temperature of approximately 30 degrees Centrigade.
2. The required product mould is then moved to area (b) where the Gelcote is applied,using standard or modified equipment - such as Binks,Bullet,Glasscraft,Robertson or similar types - after presetting such equipment to attain a ten (1 0) minute gellation.
3. The mould is then moved to area (c) for the application of the coloured pattern to the gelcoted surfaces by the use of silk screens to a predetermined design and by using one or more pigments or other such formula necessary to attain the required design.
4 . The mould is then moved to the mixing head area (e) where the formula from the bulk container (d) is mixed with catalyst from area (f) and deposited to the mould, in the preset proportions to attain a three (3) minute gellation time or such other time thatmay be required for various formulae and or existing atmospheric conditions.
Again, the mixing & depositing of the formula will bemade by use of standard or modified Binks, Bullet,Glasscraft,Robertson or similar types of equipment.
5. The product mould complete with article is then moved to the demoulding and storeage area (g) and after allowing for a curing time of approximately twenty(20) minutes,the article can be removed from the mould.
6. The mould is then returned to the heated room (a) and so completing the process cycle.
THE INDUSTRIAL APPLICABILITY OF THE INTENTION:
The invention can be used for the manufacture of all fibreglass, cultured marble and onyx products for use in the building, decorative,novelty,lei-sure and other industries. The invention is compatable for modification of the existing systems,currently in use.

Claims

CLAIMS.PART ONE:The invention has adopted the following technical features to manufacture fibreglass,cultured marble & onyx products,in addition to the established prior art and currently being used throughout the industry.
1. Preheating of moulds to approximately 30 degrees Centrigrade.
2. Continuous mixing & paddling of un-catalysei resin,celcite &. pigments whilst being stored in a stainless steel or aluminium outer container with stainless steel or aluminium fixing blades fitted to the inner - such blades to be driven by an electric motor.
3. Tepositing of tinter, pigment or other formula to the mould by the use of predesigned silk screens to achieve uniform colour and pattern to the product article.
4. Mechanical mixing & depositing of paddled formula to mould by using a modified Sinks,Bullet,Glasscraft,Robertson or similar type depositor gun When using this equipment, the mixed formula & catalyst Kill be laid on to the mould in predetermined & even proportions and so allow for a reduced gellation period for curing.
PART TWO:
With the use of the technical features as set out in Part One and the established prior art, currently in operation throughout industry, the invention is a system for the manufacture of fibreglass,cultured marble & onyx products - which the applicant seeks to protect.
The system provides for strong quality control, throughout manufacture to attain a product with uniform pattern & colour together with a reduced labour content of some 807° - when compared to present production methods using established prior art.A chart of the comparative labour content for the production of three (3) vanity tops - each 910 mm x 520 mm wide x 18 mm thickness & complete with a single bowl - using a conventional system & The Roberts System,is set out on page 2 attached.
Figure imgf000009_0001
When using the Roberts System, a saving of some 56 minutes is effected in comparison to the mechanical mix & hand pour application which is the conventional or existing art,now extensively in use.
Adapted to percentages, the use of the Roberts System reduces the labour content for each moulded product to some 20% of that produced by use of conventional or existing art systems - a saving of some80%.
