Textile printing apparatus

Claim 2

Apparatus suitable for carrying out the coloration of synthetic textile materials with a printed carrier material by a vacuum transfer printing process in an intermittent operation consisting essentially of upper and lower rigid platens mounted for relative movement towards or away from each other so that when said platens are closed, said platens cause the printed surface of said carrier material to be pressed into intimate contact with said textile material, means for heating at least one of the platens at least in the area where the carrier material and textile material are pressed together to a temperature above 100° C. so that the heat therefrom is transferred by contact to one or both of said textile material and said carrier material, sealing means for enclosing an air-tight region extending between opposed portions of the surfaces of the platens when the platens are closed so that said region is air-tight, whereby said synthetic textile material and said printed carrier material are containable within said air-tight region enclosed by said sealing means and means for evacuating the said region to a pressure of not more than 100 mm. of mercury.

Claim 3

The apparatus of claim 1 wherein the upper platen is mounted for relative movement towards or away from the lower platen which is fixed.

Claim 4

The apparatus of claim 1 wherein the upper platen is provided with means for heating it to a temperature of at least 100° C.

Claim 5

The apparatus of claim 1 wherein the lower platen is provided with a suitable connection to the evacuating means.

Claim 6

The apparatus of claim 1 wherein a porous plate of sintered stainless steel is inlaid into the lower platen and the lower side of the porous plate is connected to the evacuating means.

Claim 7

Apparatus suitable for carrying out the coloration of synthetic textile materials with a printed carrier material by a vacuum transfer printing process in an intermittent operation consisting essentially of upper and lower rigid platens mounted for relative movement towards or away from each other so that when said platens are closed, said platens cause the printed surface of said carrier material to be pressed into intimate contact with said textile material, means for heating at least one of the platens to a temperature above 100° C. so that the heat therefrom is transferred by contact to one or both of said textile material and said carrier material, sealing means for enclosing an air-tight region extending between opposed portions of the surfaces of the platens when the platens are closed so that said region is air-tight whereby said synthetic textile material and said printed carrier material are containable within said air-tight region enclosed by said sealing means, means for evacuating the said region to a pressure of not more than 100 mm. of mercury and a compensating device attached to said upper platen to maintain the original load on said textile material due to the application of the upper platen throughout the duration of the period during which vacuum is applied to the textile material.

Claim 8

Apparatus suitable for carrying out the coloration of synthetic textile materials with a printed carrier material by a vacuum transfer printing process in an intermittent operation consisting essentially of upper and lower rigid platens mounted for relative movement towards or away from each other so that when said platens are closed, said platens cause the printed surface of said carrier material to be pressed into intimate contact with said textile material, means for heating at least one of the platens to a temperature above 100° C. so that the heat therefrom is transferred by contact to one or both of said textile material and said carrier material, sealing means for enclosing an air-tight region extending between opposed portions of the surfaces of the platens when the platens are closed so that said region is air-tight whereby said synthetic textile material and said printed carrier material are containable within said air-tight region enclosed by said sealing means, means for evacuating the said region to a pressure of not more than 100 mm. of mercury and a compensating device attached to said upper platen to maintain the original load on said textile material due to the application of the upper platen throughout the duration of the period during which vacuum is applied to the textile material.

Claim 9

The apparatus of claim 6 wherein the upper platen is mounted for relative movement towards or away from the lower platen which is fixed.

Claim 10

The apparatus of claim 6 wherein the upper platen is provided with means for heating it to a temperature of at least 100° C.

Claim 11

The apparatus of claim 6 wherein the lower platen is provided with a suitable connection to said evacuating means.

Claim 12

The apparatus of claim 6 wherein a porous plate of sintered stainless steel is inlaid into the lower platen and the lower side of the porous plate is connected to the evacuating means.

Claim 13

Apparatus suitable for carrying out the coloration of synthetic textile materials with a printed carrier material by a vacuum transfer printing process in an intermittent operation consisting essentially of an upper platen which is mounted for relative movement towards and away from a lower platen so that when said platens are closed, said platens cause the printed surface of said carrier material to be pressed into intimate contact with said textile material, means for heating the upper platen to a temperature of at least 100° C. so that the heat therefrom is transferred by contact to one or both of said textile material and said carrier material, sealing means for enclosing an air-tight region extending between opposed portions when the platens are closed so that said region is air-tight whereby said synthetic textile material and said printed carrier material are containable within said air-tight region enclosed by said sealing means, evacuating means in communication with the lower platen for evacuating said region to a pressure of not more than 100 mm. of mercury, a porous plate inlaid into the lower platen to form a surface coplanar with the upper surface of the lower platen upon which said textile material or carrier material is supported during treatment, said porous plate being in communication at its lower surface with said evacuating means and a compensating device attached to said upper platen to maintain the original load on said textile material due to the application of the upper platen throughout the duration of the period during which vacuum is applied to the textile material.

Claim 14

Apparatus suitable for carrying out the coloration of synthetic textile materials with a printed carrier material by a vacuum transfer printing process in an intermittent operation consisting essentially of an upper platen which is mounted for relative movement towards and away from a lower platen so that when said platens are closed, said platens cause the printed surface of said carrier material to be pressed into intimate contact with said textile material, means for heating the upper platen to a temperature of at least 100° C. so that the heat therefrom is transferred by contact to one or both of said textile material and said carrier material, sealing means for enclosing an air-tight region extending between opposed portions when the platens are closed so that said region is air-tight whereby said synthetic textile material and said printed carrier material are containable within said air-tight region enclosed by said sealing means, evacuating means in communication with the lower platen for evacuating said region to a pressure of not more than 100 mm. of mercury, a porous plate inlaid into the lower platen to form a surface coplanar with the upper surface of the lower platen upon which said textile material or carrier material is supported during treatment, said porous plate being in communication at its lower surface with said evacuating means and a compensating device attached to said upper platen to maintain the original load on said textile material due to the application of the upper platen throughout the duration of the period during which vacuum is applied to the textile material.
