DETAILED DESCRIPTION OF THE DRAWINGS

[0047] FIG. 1 schematically shows a sectional side view of a laminating apparatus 10 for carrying out a method 300 for heat-setting and laminating a 3D knitted fabric. The laminating apparatus includes a force-exerting device 12, a temperature device 14, an impregnating device 16, an addition device 18, and a radiating device 20. The force-exerting device 12 of the laminating apparatus 10 is designed for applying force 308 (not shown) to the 3D knitted fabric 100 and to the hot-melt adhesive yarn 102 for the activation 304 (not shown) of the hot-melt adhesive yarn 102. The temperature device 14 of the laminating apparatus 10 is designed for controlling the temperature 314 (not shown) of the 3D knitted fabric 100 and of the hot-melt adhesive yarn 102. The impregnating device 16 of the laminating apparatus 10 is designed for impregnating 310 (not shown) the 3D knitted fabric 100 and the hot-melt adhesive yarn 102 with an activation medium, the activation medium comprising an acrylate. The addition device 18 of the laminating apparatus 10 is designed for adding 312 (not shown) a catalyst medium to the 3D knitted fabric 100 and to the hot-melt adhesive yarn 102 for the activation 304 (not shown) of the hot-melt adhesive yarn 102.
