Continuous teaseling machine

Garzatrice continua

Leonardo devised this interesting machine, in his endeavour to produce teased lengths of wool. Soaked in an alkaline solution, wool fibres emerge compact and stiff, with a tangle of filaments jutting out. Teaseling consists in tidying and straightening this tangle, by raising and smoothing the filaments in order to make that characteristic fibre which makes wool capable of retaining heat.
