## Abstract

A device for preparation of double fabric for down products comprises a printing means that can print an adhesive in a predetermined printing pattern on fabric; a drying means that can dry or fix the adhesive; a laminating means that can stack and laminate the fabrics on which an adhesive is printed; and a bonding means that can bond the fabrics with a cured adhesive by pressing with a predetermined pressing means and high-frequency heating to cure the adhesive; wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less. Consequently, double fabric for down products thus manufactured has an excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality.

## Claims

### Claim 1

A device for the preparation of a double fabric for down products, which comprises a printing means, a drying means, a laminating means and a bonding means as follows:
a printing means which is provided with a printing apparatus carved with a predetermined printing pattern and which can print an adhesive in said printing pattern on a fabric;
a drying means which can dry or fix the adhesive so that the adhesive printed on the fabric is not transferred during a laminating process;
a laminating means which can stack and laminate the fabrics on which an adhesive is printed; and
a bonding means which is provided with a pressing means on which a protrusion having a predetermined pressing pattern is formed and which can bond fabrics with the adhesive by pressing with said pressing means and high-frequency heating to cure the adhesive;
wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less.

### Claim 2 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said printing means can selected from a group consisting of a stamping printing means, a pressing press printing means, a roller printing means or a screen printing means.

### Claim 3 (depends on 2)

The device of manufacturing a down product according to claim 2, characterized in that, a groove having a predetermined pattern is formed in a depth of 0.5˜10 mm on said printing press or roller.

### Claim 4 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said printing means is provided with both of an adhesive printing means for inner fabric and an adhesive printing means for outer fabric.

### Claim 5 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said drying means is a hot wind dryer or a tenter.

### Claim 6 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said laminating means further comprises a first alignment means (the means for adjusting the fabric location) to adjust the relative positions between the location of the adhesive printing pattern at the upper fabric and the location of the adhesive printing pattern at the lower fabric.

### Claim 7 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said bonding means further comprises pressing means which can be selected from a pressing press or roller.

### Claim 8 (depends on 7)

The device of manufacturing a down product according to claim 7, characterized in that, a protrusion having a predetermined pattern is formed in a height of 5˜20 mm on the surface of said pressing press or roller.

### Claim 9 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said bonding means is a dielectric heating apparatus employing a high frequency of 5 MHz˜50 MHz.

### Claim 10 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said bonding means comprise a second alignment means which can control the position of the adhesive printed on a fabric or the position of the protrusion to adjust their relative positions.

### Claim 11 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said second alignment means can adjust and overlap the relative positions of said printing pattern and pressing pattern by coinciding the center line of the printing pattern of the adhesive with the center line of the pressing pattern of the protrusion.

### Claim 12 (depends on 1)

The device of manufacturing a down product according to claim 1, characterized in that said printing pattern of the printing means and said pressing pattern of the pressing means have a width of 1˜10 mm, respectively.
