PURPOSE:To prevent winding of a stretch-broken fleece or a part thereof around a final stretch-breaking roller, by placing a collection guide at a position separated from the final stretch-breaking roller by a specific distance and collecting the stretch-broken sliver under a specific condition. CONSTITUTION:A tow (a) is passed through a final stretch-breaking zone A, collected with a collection guide 10, transferred to a trumpet 7 in the form of a sliver (b) and the stretch-broken sliver (c) is delivered to the subsequent step with a sliver-feeding roller 8. The position of the collection guide 10 is separated from the grip point 14 of the final stretch-breaking roller by a distance of l/5-2l [l is average fiber length (mm) of the stretch-broken sliver], the right and the left collection angles are set to 10-80 deg. each and the total denier of the stretch-broken sliver per unit width at the position of the collection guide is adjusted to 300-1,300d/mm.
