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.
Claims12
An apparatus for forming strips of mineral fibers into compressed fiber rolls, comprising:
- a plurality of members defining a space in which the strip is rolled;
- means for rolling said strip to form a roll;
- means for moving at least one of said members in relation to others of said members in such a manner that said space is altered in accordance with a size of a roll being formed, wherein said at least one of said members each comprises a roller having a felt contacting surface in the form of regularly disposed relief elements;
- and
- an abrasion resistant inorganic coating on at least a portion of said felt contacting surface of said roller.
