DEVICE AND PROCESS FOR FORMATION OF LAYERS OF ROCK WOOL FIBRES AND SIMILAR FIBROUS INSULATING MATERIALS

摘要

A device for formation of layers of rock wool fibres and similar insulating materials consists of a conveyor (1) of a collecting chamber, a take-off conveyor (2), at least two two-parted swivelling belts (3, 5), at least one feed-in conveyor (4), and at least one loading conveyor (6). Fibres are transferred from the conveyor (1) to the take-off conveyor (2), from the latter between the first pair of double upright swivelling belts (3) which are depositing fibres during the zigzag movement on the first feed-in conveyor (4), and from this one between the second pair of double upright swivelling belts (5) which are depositing fibres during their zigzag movement on the first loading conveyor (6). The zigzag depositing may be repeated in such a manner that the fibrous layer before the curing chamber consists of two or several transverse depositions turned to each other for 90 degrees.
