A cryst. opaque sheet of thickness 0.55 mm. min. or a cryst. transparent film may be used. Thermoforming is by usual vacuum- and/or pressure-assisted methods, with pre-heated material being formed into a cold mould. The process is suitable for making deep-drawn articles for packaging, boxes, covers and containers. Use of polyesters with high mol. wt. gives better physical properties, esp. strength e.g. resistance to breaking by brittleness.

Plastic sheet vacuum moulded directly against mould - to produce optical finish by pre-heating before moulding

Hot vacuum moulding a plastic (e.g., methacrylate sheet by securing it at its edges to a mould by means of a brace, around the edge of the mould being mounted in a treatment chamber of which the pressure and temp. can be controlled. The sheet is pre-heated to roughly mould it without damage, and then heated to 107 degrees-115 degrees C whilst an increasing suction is applied through apertures in the mould to form the sheet against the mould. The method is used for forming transparent windows for various vehicles. The plastic sheet can be moulded directly against the mould without a surrounding jacket and still have an optically smooth surface.

Thermo:formed plastic crockery preprinted on the underside - to prevent contact between the printing inks and the food

Disposable crockery is made from transparent thermoplastic sheet printed on the underside and then thermoformed to the shape required for a plate, dish, etc. The print pattern is modified to compensate for distortion of the surface by the thermoforming process. The sheet is preprinted in several columns, pref. using heat dried inks and collected as a roll of flat sheet before being led into the slower thermoforming cycle. The printing inks are protected from contact with the food by transparent body of the article more reliably than use of paper or plastic crockery having printing on the upper face exposed or protected only by a thin coating.

IMPROVEMENTS IN THE MOLDING OF PLASTIC FILMS

L'invention concerne un procédé de formage d'un récipient, destiné à l'empaquetage d'un objet ou d'un produit, à partir d'une matière plastique flexible. Ce procédé consiste à mouler le film dans une cavité de matrice pour y former un enfoncement ayant une surface dont l'étendue et le périmètre sont essentiellement égaux à ceux de la surface intérieure du récipient désiré. Le contour de l'enfoncement est toutefois différent du fait que la partie du film moulé correspondant à une jonction entre des parois adjacentes du récipient a un rayon de courbure supérieur à celui de cette jonction. La matière en excès forme une protubérance à l'intérieur de l'enfoncement. On modifie ensuite le contour du film moulé pour obtenir le récipient de la forme et de la dimension désirées. Application à l'empaquetage des objets ou des produits. The invention relates to a method of forming a container, intended for packaging an object or a product, from a flexible plastic material. This method involves molding the film in a die cavity to form a recess therein having an area the extent and perimeter of which are substantially equal to that of the interior surface of the desired container. The contour of the recess is however different in that the part of the molded film corresponding to a junction between adjacent walls of the container has a radius of curvature greater than that of this junction. The excess material forms a protuberance within the indentation. The contour of the molded film is then modified to obtain the container of the desired shape and size. Application to the packaging of objects or products.

PROCESS FOR TRANSFORMATION AND TRANSFER PRINTING ON PLASTIC MATERIAL

L'INVENTION CONCERNE UN PROCEDE DE CHANGEMENT DE FORME ET D'IMPRESSION PAR TRANSFERT DE PRODUITS SEMI-FINIS THERMOPLASTIQUES OU COMPORTANT AU MOINS UNE COUCHE SUPERFICIELLE EN MATIERE PLASTIQUE SUSCEPTIBLE D'ETRE DEFORMEE. ON TRANSFORME LE PRODUIT SEMI-FINI1 SE TROUVANT A LA TEMPERATURE DE CHANGEMENT DE FORME EN UTILISANT LA PRESSION OU LE VIDE AU MOYEN D'UN OUTIL DE MODELAGE2 DANS LEQUEL LE CONTRE-MOULE CORRESPONDANT A LA SURFACE4 DU PRODUIT1 DESTINEE A L'IMPRESSION PEUT ETRE CHAUFFE ET ESTCHAUFFE A UNE TEMPERATURE APPROPRIEE POUR LE TRANSFERT DE COLORANTS. UNE COUCHE COHERENTE5 DE MATIERE SUSCEPTIBLE D'ABSORBER DE L'EAU, LEGEREMENT HUMIDIFIEE, SE TROUVE A LA SURFACE DU CONTRE-MOULE3. LE SUPPORT COULEUR PLAN6 APPROPRIE POUR L'IMPRESSION PAR TRANSFERT CONSTITUE UNE COUCHE QUI LA SURPLOMBE. LA SURFACE4 DU PRODUIT SEMI-FINI1 EST AMENEE AU CONTACT DU SUPPORT COULEUR6 SOUS L'EFFET DE LA PRESSION OU DU VIDE. THE INVENTION CONCERNS A PROCESS FOR CHANGING SHAPE AND PRINTING BY TRANSFER OF THERMOPLASTIC SEMI-FINISHED PRODUCTS OR CONTAINING AT LEAST ONE SURFACE LAYER OF PLASTIC MATERIAL LIKELY TO BE DEFORMED. THE SEMI-FINISHED PRODUCT1 IS TRANSFORMED AT THE TEMPERATURE OF CHANGE OF SHAPE BY USING PRESSURE OR VACUUM BY MEANS OF A MODELING TOOL2 IN WHICH THE COUNTERMOLD CORRESPONDING TO THE SURFACE4 OF THE PRODUCT1 INTENDED FOR PRINTING CAN BE HEATING AND HEATING TO AN APPROPRIATE TEMPERATURE FOR THE TRANSFER OF COLORANTS. A COHERENT5 LAYER OF MATERIAL LIKELY TO ABSORBING WATER, SLIGHTLY WET, IS LOCATED ON THE SURFACE OF THE COUNTERMOLD3. PLAN6 COLOR MEDIA SUITABLE FOR TRANSFER PRINTING CONSTITUTES A LAYER OVERLOADING IT. THE SURFACE4 OF THE SEMI-FINISHED PRODUCT1 IS BROUGHT INTO CONTACT WITH THE COLOR6 SUPPORT UNDER THE EFFECT OF PRESSURE OR VACUUM.

Three-dimensional fabric embossing process - uses vibrating die to give localised application of heat and pressure

A three-dimensional effect is obtd. on textile or leather matls. using an oscillating die with local thermal applications to give localised shrinking through heat and pressure on the stretched matl. The process imposes a structured three-dimensional effect on the matl. which is permanent, and will not be lost during usage or subsequent cleaning.
