摘要：
The draw group - combined with the card - comprises several pairs of rotating cylinders (7,9), both the cylinders of each pair being driven into rotation to drag the web (B) passing therebetween; the cylinders (7,9) of a subsequent pair are provided with a peripheral speed greater than that of the cylinders (7,9) of the preceding pair, in order to cause a partial draw; the cylinders of adjacent pairs graze one another thus obtaining a self-cleaning effect; the two cylinders (7,9) of each pair are provided with metal surfaces and one of them is elastically urged towards the other.
