A method and apparatus for shaping of fabrics

摘要

In the field of shaping fabrics there is a need for a method and apparatus for the shaping of fabrics which utilises ultrasonic techniques while improving the versatility of being able to change the profile to be cut/embossed. A method of shaping fabric comprises creating a former having a surface relief which defines the desired profile and/or surface pattern, placing the fabric to be shaped onto the former to overlie said surface relief and remain in a fixed position relative thereto, and sweeping an ultrasonic head in at least two dimensions over the area of fabric overlying the former whilst pressing the fabric between said head and the former such that the profile and/or surface pattern on said former is transferred to said fabric.
