FR2704579A1 - Preglued tiles (slabs) and accessories - Google Patents

Abstract

Pregluing of tiles and accessories made of expanded and moulded synthetic material, or cork, using an adhesive and protecting it with a sheet of paper that is siliconised on one side.

Description

The present invention relates to a method of fixing and installing slabs and accessories of expanded synthetic material, with variable physical characteristics, predetermined according to the application, such as mechanical characteristics, thermal or sound insulation characteristics, as well as slabs and accessories in natural product such as cork.

As is known, the slabs and accessories molded in expanded synthetic material, in particular in expanded polystyrene, as well as in cork, due to their lightness, are of an easy and easy handling, within the reach of all physical persons and of constitution. normal.

The invention proposes to create means for laying slabs and accessories in molded synthetic material, having all or some of the predetermined physical characteristics, or natural product such as cork.

To this end, the present invention relates to a method of laying slabs and accessories in expanded synthetic material, in particular in expanded polystyrene, as well as in cork, a process according to which the laying becomes easier, faster, and without any tools.

The current laying of these synthetic tiles and accessories is done using paste adhesive placed on the back of these tiles and accessories, using a spatula.

The installation of these tiles and accessories requires frequent handling and movement of the natural person, environmental protection for possible drops of glue, cleaning of the tools after use and special attention to their own clothes.

The present invention consists in gluing these slabs and accessories at the end of the production line, with an adhesive adapted to the material, and in protecting this adhesive with one. sheet of silicone paper.

With this process, more cleaning of tools, more environmental protection, less movement and handling, ease of installation, huge time savings, and the possibility of doing this intervention without having to change.

Mode of realization
I. Gluing
a / By a glue and scraper roller system which will prevent
deposit an extremely thin layer of glue on these slabs or
accessories.

b / By a glue gun and directional nozzle system, with a
running speed of the parts to be glued, linked to the time of
spraying glue for an even and thin layer on these
tiles and accessories.

The principle a / or bl will be managed and automated by sensors and eye
electronic, or other operating mode, depending on the
chain, type of material chosen, product and other choices.

2. Drying
a / If the glue used is a water-based glue, a drying of
10 to 15 seconds is necessary, and will be achieved using a
hot air blower (recovered from production line), air
at about 50 "C, and blown by a ramp 10 cm from the support
glued. (SEE EXAMPLE NO l
b / No drying if a synthetic adhesive with evaporation is used
direct and instant. (SEE EXAMPLE NO.2 3. Installation of the paper protection by a suction system
(paper pre-cut to size), this paper being siliconized on the
face in contact with the glue.

4. Packaging as already used at the end of the chain for slabs or
accessories not pre-glued. The installation of these slabs or
pre-glued accessories is identical to non-pre-glued.
