Abstract
Abstract The process to heat strands of fibrous materials so that they are bonded to each other at the points of contact, such as for cigarette filters without paper containing shells, uses fibres of dielectric material passed through an electric or electro-magnetic field of more than 3.108 Hz and less than 3.1011 Hz. The process provides an effective and intensive heat application, under controlled conditions, allowing high throughput speeds.
