Method of applying heat-sealable marking labels for flexible articles

Claim 1

A METHOD OF PRODUCING PERMANENT MARKINGS OF FLEXIBLE ARTICLES COMPRISING APPLYING UNDER HEAT AND PRESSURE A TRANSFER CONSISTING OF A TEMPORARY SUPPORT HAVING RELEASE PROPERTIES AND HAVING PRINTED THEREON A PATTERN OR MARKING CONSISTING OF DISTINCT INFORMATIVE CHARACTERS INCORPORATING A HEAT-CURABLE RESIN SYSTEM AND A PIGMENT, THE HEAT AND PRESSURE SERVING TO BOND THE CHARACTERS TO THE SURFACE OF THE ARTICLE AND TO EFFECT CURING OF THE RESIN, IN WHICH THE CHARACTERS OF THE TRANSFER ARE EACH COVERED WITH A SUPERIMPOSED LAYER OF A CLEAR HEAT-CURABLE RESIN SYSTEM IN A MANNER TO OVERLAP THE ARTICLE TO BE MARKED THE CHARACTERS AND WHICH IS BONDED TO THE ARTICLE TO BE MARKED WITH THE CHARACTER SUPPORTED PRIMARILY BY THE CLEAR RESIN WITHOUT PROVIDING A CONTINUOUS LAYER OVER THE WHOLE AREA OF THE PERMANENT MARKINGS. M , SAID TRANSFER BEING PREPARED BY FIRST PRINTING THE CHARACTERS ON THE TEMPORARY SUPPORT WITH A FINE SCREEN MESH AND THEN PRINTING THE SUPERIMPOSED LAYER OF CLEAR RESIN SYSTEM ON THE CHARACTERS WITH A COARSE SCREEN MESH, EACH OF SAID SCREENS INCLUDING A PHOTOGRAPHICALLY PRODUCED STENCIL, THE STENCIL ASSOCIATED WITH THE COARSE SCREEN MESH BEING OF INCREASED SIZE TO INCREASE THE SIZE OF THE PRINTING AREA IN EVERY DIRECTION AND TO ENSURE THAT THE CLEAR HEAT-CURABLE RESIN LAYER OVERLAPS THE CHARACTERS PRODUCED BY THE FINE SCREEN MESH IN ALL DIRECTIONS SAD INCREASE IN SIZE BEING CARRIER OUT PHOTOGRAPHICALY BY INTERPOSING A THICK SHEET OF TRANSPARENT FILM BETWEN A POSITIVE AND THE STENCIL TO SCATTER THE PROJECTED LIGHT.

Claim 2

A METHOD OF PRODUCING PERMANENT MARKINGS OF FLEXIBLE ARTICLES COMPRISING APPLYING UNDER HEAT AND PRESSURE A TRANSFER CONSISTING OF A TEMPORARY SUPPORT HAVING RELEASE PROPERTIES AND HAVING PRINTED THEREON A PATTERN OR MARKING CONSISTING OF DISTINCT INFORMATIVE CHARACTERS INCORPORATING A HEAT-CURABLE RESIN SYSTEM AND A PIGMENT, THE HEAT AND PRESSURE SERVING TO BOND THE CHARACTERS TO THE SURFACE OF THE ARTICLE AND TO EFFECT CURING OF THE RESIN, IN WHICH THE CHARACTERS OF THE TRANSFER ARE EACH COVERED WITH A SUPERIMPOSED LAYER OF A CLEAR HEAT-CURABLE RESIN SYSTEM IN A MANNER TO OVERLAP THE ARTICLE TO BE MARKED THE CHARACTERS AND WHICH IS BONDED TO THE ARTICLE TO BE MARKED WITH THE CHARACTER SUPPORTED PRIMARILY BY THE CLEAR RESIN WITHOUT PROVIDING A CONTINUOUS LAYER OVER THE WHOLE AREA OF THE PERMANENT MARKINGS. M , SAID TRANSFER BEING PREPARED BY FIRST PRINTING THE CHARACTERS ON THE TEMPORARY SUPPORT WITH A FINE SCREEN MESH AND THEN PRINTING THE SUPERIMPOSED LAYER OF CLEAR RESIN SYSTEM ON THE CHARACTERS WITH A COARSE SCREEN MESH, EACH OF SAID SCREENS INCLUDING A PHOTOGRAPHICALLY PRODUCED STENCIL, THE STENCIL ASSOCIATED WITH THE COARSE SCREEN MESH BEING OF INCREASED SIZE TO INCREASE THE SIZE OF THE PRINTING AREA IN EVERY DIRECTION AND TO ENSURE THAT THE CLEAR HEAT-CURABLE RESIN LAYER OVERLAPS THE CHARACTERS PRODUCED BY THE FINE SCREEN MESH IN ALL DIRECTIONS SAD INCREASE IN SIZE BEING CARRIER OUT PHOTOGRAPHICALY BY INTERPOSING A THICK SHEET OF TRANSPARENT FILM BETWEN A POSITIVE AND THE STENCIL TO SCATTER THE PROJECTED LIGHT.

Claim 3

A method of marking flexible textile articles comprising a. forming a marking element by applying a plurality of marking characters comprising a heat-curable resin ink to a temporary support having release properties, and then applying a superimposed layer of a clear heat-curable resin system overlapping the boundary edge of each of said characters but not as a continuous layer over the entire area of said plurality of characters, said marking characters and superimposed layer being applied to said temporary support by a fine screen mesh and a coarse screen mesh respectively, each of said screens including a photographically produced stencil, the stencil associated with said coarse screen mesh being prepared photographically by interposing a thick sheet of transparent film between a positive and the stencil to scatter the projected light to increase the size of the printing area in every direction and to ensure that the clear heat-curable resin layer overlaps in all directions each of the characters printed on the temporary support by said fine screen mesh, b. applying said marking element to an area of a flexible textile article with said superimposed layers contiguous to said fabric, c. applying heat and pressure to said temporary support sufficient to cure and bond said superimposed layers with said characters to said textile article, and d. removing said temporary support from said bonded superimposed layers and characters, e. whereby said textile fabric remains flexible in the area where said plurality of superimposed layers and characters are applied.

Claim 4

A method of marking flexible textile articles comprising a. forming a marking element by applying a plurality of marking characters comprising a heat-curable resin ink to a temporary support having release properties, and then applying a superimposed layer of a clear heat-curable resin system overlapping the boundary edge of each of said characters but not as a continuous layer over the entire area of said plurality of characters, said marking characters and superimposed layer being applied to said temporary support by a fine screen mesh and a coarse screen mesh respectively, each of said screens including a photographically produced stencil, the stencil associated with said coarse screen mesh being prepared photographically by interposing a thick sheet of transparent film between a positive and the stencil to scatter the projected light to increase the size of the printing area in every direction and to ensure that the clear heat-curable resin layer overlaps in all directions each of the characters printed on the temporary support by said fine screen mesh, b. applying said marking element to an area of a flexible textile article with said superimposed layers contiguous to said fabric, c. applying heat and pressure to said temporary support sufficient to cure and bond said superimposed layers with said characters to said textile article, and d. removing said temporary support from said bonded superimposed layers and characters, e. whereby said textile fabric remains flexible in the area where said plurality of superimposed layers and characters are applied.
