Method for making sheet materials such as security paper |
abstract |
In a method of making sheet materials such as security paper having partially embedded therein an elongate security element (20) which is partially disposed within the thickness of the sheet and exposed at spaced locations, fibres (24) are deposited onto a moving support surface (11) and the security element (20) is introduced into the fibres by rotating embedment means (14) having a plurality of spaced-apart raised portions (16) with recesses (17) therebetween, so that some fibres move into said recesses between the security element and the embedment means so that said security element is covered by fibres while fibres are substantially prevented from penetrating under the raised portions. The security element (20) may be laid in an oscillating path. The embedment means (14) may additionally impress a watermark. <IMAGE> |
