Abstract
Abstract Pile fabrics with a pile containing thermoplastic fibers are thermoprinted with a pattern, the contact pressure between the pile fabric and the thermoprinting web in the heating zone being such that about 40 to 60% of the pile is compressed, and immediately afterwards relief-formed and/or surface formed while still hot with a pattern which bears a strict relationship to the thermoprinted pattern. A machine for carrying out this process comprises a thermoprinting unit with adjustable contact pressure and a relief-forming and/or surface forming patterning unit which functions in synchronism and coordination therewith.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
A machine for printing pile fabrics containing thermoplastic fibres, comprising a. means conveying said pile fabric through a printing zone, b. a thermoprinting web containing sublimable dyes, and means for winding and guiding said web into contact with the pile of said pile fabric and the web away from said pile fabric after heating thereof, c. flat heating means, the lower surface of which engages said thermoprinting web for heating the thermoplastic fibres of the pile to a temperature at which they begin to undergo plastic deformation, d. guide means for supporting said pile fabric, said guide means being positioned below and spaced from said heating means, e. means for vertically adjusting said guide means toward or away from said heating means to adjustably compress the pile fabric between said guide means and said heating means to effect sublimation of the dyes into the heating thermoplastic fibres, and f. an embossing roller positioned beyond the printing area for embossing the printed pile fabric, and means for synchronizing the movement of said thermoprinting web and said embossing roller to permit coordination between the printed color and the embossed pattern on the pile fabric.
Claim 2
Dependent Claim
192 words
A machine for printing pile fabrics containing thermoplastic fibres, comprising a. means conveying said pile fabric through a printing zone, b. a thermoprinting web containing sublimable dyes, and means for winding and guiding said web into contact with the pile of said pile fabric and the web away from said pile fabric after heating thereof, c. flat heating means, the lower surface of which engages said thermoprinting web for heating the thermoplastic fibres of the pile to a temperature at which they begin to undergo plastic deformation, d. guide means for supporting said pile fabric, said guide means being positioned below and spaced from said heating means, e. means for vertically adjusting said guide means toward or away from said heating means to adjustably compress the pile fabric between said guide means and said heating means to effect sublimation of the dyes into the heating thermoplastic fibres, and f. an embossing roller positioned beyond the printing area for embossing the printed pile fabric, and means for synchronizing the movement of said thermoprinting web and said embossing roller to permit coordination between the printed color and the embossed pattern on the pile fabric.
Claim 3
Dependent Claim
56 words
The machine according to claim 1, in which said guide means is provided with a screw threaded spindle for adjustment of said guide means relative to said heating means, said adjustment permitting said pile to be compressed 40 to 60 % of its thickness before entering the space between said guide means and said heating means.
Claim 4
Dependent Claim
27 words
The machine according to claim 1, in which said embossing roller cooperates with a counter roller to form a nip through which the printed pile fabric passes.
Claim 5
Dependent Claim
17 words
The machine according to claim 3, in which said embossing roller is provided with a cooling system.
