Abstract
In the packaging of products such as rolls of mineral wool felts, a series of members entrain the felt into a space in which the rolling-up takes place. At least one of these members is mobile in relation to the others in order to alter the size of the space in which the rolling-up takes place as the roll of felt increases in size. This movable member is a roller whose surface contracting the felt is covered with an inorganic coating resistant to abrasion and adapted to have a rough finish.
