<p>Roller blinds manufactured from rolls of fabric require cutting of the fabric corresponding to the width of the finished roller blind. Traditionally, a cutting device suitable for the fabric is mounted on the cutting machine, and it is also used even when less suitable for a particular fabric. Compound fabrics are traditionally manufactured in a completely different manner. According to the invention, a fast- acting change-over is obtained between two or more cutting devices so that the active cutting device is alway an appropriate cutting device. Compound fabrics may be cut with a change-over during what becomes a continuous cutting operation.</p> |
