  Patent application by TECHNIQUES ET PEOCEDES COFPA S.A.R.L. street

  du Bois-Rouquin - industrial zone no2 - 37110 CHiATEAU-RENAULIT.

  The present invention relates to a method of manufacturing a material for

  wall covering intended to simultaneously provide decoration, insulation and

  thermal and sound insulation, protection against condensation, at competitive prices compared to wall coverings: paint, paper or

  other materials, all made on a machine of the design of the invention.

  in a single passage in a possible width of up to three mAtres, thereby eliminating the need for

standardis4es.

  Many products have been made for wall decoration, for example paper textiles, collages or flammages of fabrics on foam

  of various qualities and compositions. All these products bring benefits

  some of them in the decoration and isolation of the habitat but all have

  cost prices are prohibitively expensive and are not designed differently from

  The novelty and invention of COFPRA consisted in carrying out from several

  a variety of materials, a complexing of these products, to create a machine necessary for the realization of the material, object of the invention and to obtain a product whose price, provided laid to the consumer will not exceed that of a conventional wall paper , providing an acoustic absorption of OC-0,?, according to

  frequencies and a decrease in noise from C to r decibels.

  The product used in wall covering also removes thermal bridges

  on the cold walls of the walls. This isolation is concretized by a

  temperature in the room from 1 to 3 c, depending on the quality of the

  already existing wall, and the surface importance of the parts of the

  piece exposed in direct cold.

  It should be noted that the results obtained in energy saving are increasing according to the insulating quality of the walls: a wall is bad insulation,

the more our material will be effective.

  T.a suppression of thermal bridges also eliminates the condensation

  internally on walls or ceilings, creating moisture and molds. The man

  teriau resulting from the complexing being 100/100 synthetic, no deterioration

can be created by moisture.

  In addition to the technical qualities of thermal and acoustic insulation and anticon-

  densification, the material brings economic advantages.

  It can be placed glued-stretched, that is to say with the help of a film of coll-n periphery of the piace. This advantage increases its insulating power Cn creating a thin air gap between the wall and the material, not to mention the low cost of glue. It can also be used in full bonding, but its power

  insulation decreases slightly as a result.

  The characteristic economic advantages of the material that can be realized up to three meters wide, are the removal of the preparation of the walls, the direct laying on concrete of formwork or agglomerates. It can be used in low-rent housing either in nine or in renovation without increasing the cost of construction.

  The manufacturing process, which is the subject of the patent claim, consists

  simultaneously, with rigorously equal tensions, the foam (1),

  the adhesive tape (3), the synthetic textile (2) and the pre-imitation transfer paper

  awarded (4), all in the above-mentioned order so that the (i) is directly introduced the first, unprinted face plated on the cylinder, then the

  nonwoven (2), adhnif film (3) and foam (1).

  all four alarms are plated by a conveyor belt formed of an endless teflon mat, the tension of which is regulated by a tensioner (7)

  compressing around a heating cylinder the four elements.

  I cylinder heated to 2100C approximately by heating resistors drowned dane

  thermofluid oil, transfer by contact its heat to the elements in pre-

  sence, causing on the one hand the migration of dyes from the paper to the

  synthetic textile port, and also by putting the plastic film at the point of ramoalissement-collage, the latter ensuring, by thermo-welding, the link:

  between the foam and the printed textile.

  rar continuous scrolling, all three elements is delineated by scissors

  Electric in (11); the paper used for printing is recovered by

  bearing in (8) and the finished product wound by the center on cardboard tube in (10).

  The device comprises a steam suction hood (12), whose exhaust

  air intake is to the outside, with recovery by a channel in (12)

  cutting waste to transport them pneimatically outside.

  The entire system operates continuously, the speed of manufacture being the result of the contact temperature setting of the materials to be welded and

  to be printed. It can vary according to the development of the heating cylinder.

  ghost and the necessary duration of contact to get the temperature up

  of all the elements to collect and print.

  The present invention relates to a wall covering intended for decoration, but mainly to the acoustic correction and the thermal insulation of the habitat whose cost price on a wall is identical to a painting or wall paper,

  Product Description; its composition is characterized by X

  1. First component - the surface textile - a textile web of staple polyester fibers, fibers intermixed without binders so as to constitute a structure resembling a traditional textile weave. It is micro-perforated or not for

  give the appearance of a classic weave.

  2. Second component - an extruded and blown polyethylene film, specially treated to have a heat-sealing power between 180 and 2000C

  The structure is designed to crack at the time of heat sealing in order to

  serve the possibility of air exchange between the wall and the internal wall (Ir, In room.

  It is also possible, for technical purposes, to use plastic films.

  ticks do not crack during lamination and thus form a barrier

  completely impervious to air.

  This film is also used as an anti-ultraviolet barrier because polyether or polyester foams tend to oxidize under the effect of ultraviolet

and take a yellow coloring.

  3. Third component - polyether foam. It can be used other plastic foams such as polyester or latex, etc. We chose in the complexing the polyether foam for technical reasons on the one hand, imputrescibilité (very good aging), on the other hand, autoextinguibilit s this material plaqué auit

wall does not lead the flame.

  It was therefore for safety reasons that it was chosen in relation to the others

synthetic foams from the trade.

  In the product, object of the invention, its thickness can vary from 1 to 10 mm and more. But the best technical results, transposed in price-quality, were obtained with a thickness of 3 mm. It is this thickness that the inventor

  chosen for the marketing of its material.

  But, depending on the needs of specific isolations, the thickness can be increased

  the use of the textiles forming the surface of the product, the claim also covers all woven and non-woven synthetic textiles used in

  process design defined by the inventor.
