DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The object of the present invention is a process and a machine for the manufacture of vulcanised decorated and multi-coloured mats and the mats thus obtained, which are of such a type that their active side is virtually defined by the points of a multitude of nubs which, in uniform distribution, emerge vertically from a mat body which fulfills the functions of a base resting upon the floor.
A first characteristic of this invention is a process aimed at incorporating in the vulcanised mat obtained multicoloured decorative designs which are imaginatively predetermined.
A second characteristic of the invention is the design of a machine capable of applying the above-mentioned manufacturing process.
A third characteristic is that the vulcanised mat is of a monobloc construction and is composed of different layers, consisting of a base layer, which supports another or other upper ones, in which cavities are arranged. From these emerge the uniformly distributed nubs, which are trunco-conical with spherical tips and whose points define the discontinuous and soft surface upon which the user treads.
Some of the layers may be arranged on the same surface level and all of them incorporate determined colours in their mass in such a way that, due to the arrangement of the cavities, different colours emerge which, appropriately distributed in the layers, define various images.
By virtue of the three dimensional structure of the nubs and their different placing, aligned or in quincunxes, as well as the varying perspective of the observer and his distance from the nubs, these images are perceived as changing and of a holographically generated style, which stimulates the attention of users.
BACKGROUND OF THE STATE OF THE ART
Currently, the only process used to decorate nubbed mats is by painting the multicoloured design in question on the tips of the nubs.
This process is not very effective because with use the paint which was applied comes off and soon the most intensively used parts of the decorative design disappear, so that the decorative design becomes completely disfigured even though the mat is practically new.
On the other hand, nub mats manufactured by the traditional vulcanising press process are of the same colour throughout or, if more than one colour is featured, these are randomly distributed, because such traditional methods do not allow of an ordered distribution of different colours of rubber material in the vulcanising mould such that the mat obtained displays a predetermined colour pattern, at least when this is to be achieved by an industrial process rather than by craftsmanship.
EXPLANATION OF THE INVENTION AND ITS ADVANTAGES
In the face of this state of affairs, the new process propounded here will ensure that the multi-coloured decorative design is integrated in the very mass of the nubs; so that the design will endure in all its splendour even when the nubs begin to wear through use, since the new substratum which will be revealed has the same colour as the worn down surface and will retain it until the nubs are completely worn away, or what amounts to the same, until the end of the mat's useful life.
To this end, according to this new process, in a first operation, the cutout or cutouts with their respective outlines and colours corresponding to the different parts which make up the chosen decorative design are prepared in untreated rubber.
In a second operation, the untreated rubber base is made with a perimeter corresponding to the mat to be manufactured.
In a third operation, these decorative cutouts are put in their exact places upon the above-mentioned untreated mat-base.
In a fourth operation, the untreated ensemble obtained consisting of mat-base and decorative cutouts, is placed in a punch--press which is a kind of inverse action vulcanising press, in such a way that the untreated ensemble rests on the base provided by the lower housing of the punch--press which operates in relation to a corresponding upper punch--cover whose active side is formed by a multitud
