Abstract: A hooking device (1) for moving systems of rolling cylinders comprises a lifting structure (30-32) of a cylinder (50) provided with gripping means (4) of said cylinder (50) and upper hooking means (10) suitable for keeping said device (1) in a raised position, said device (1) also comprising tilt compensation means. According to the invention, said tilt compensation means comprise a series of guides (100, 120), each guide (100, 120) being provided with at least one mass element (200, 220), said at least one mass element (200, 220) being moveable along said guide (100, 120).

Abstract: It is provided a fibering device for making insulating glass fibers in which the gas fiber coming out of a rotor (3) driven in rotation around its axis is maintained to a viscous state and stretched by means of two blower units capable of directing the respective flows towards the fibers coming out of the rotor (3). The second blower unit (8) consists of a plurality of nozzles (10) for delivery of an air flow, which nozzles can be rotated about a respective axis (B) that is transverse to the rotation axis (A) of the rotor. Through movement of the nozzles (10), the point of incidence of the second flow (9) on the fibers is modified so that the stretching degree of the fibers is consequently varied.

Abstract: A rolling-mill stand comprises, in combination: at least two rolls (15) supported by respective mounts (16, 17) with adjustment and blocking tie rods (18, 19), supporting feet (20), and supports (20a). According to the invention, the said rolls (15) are mounted on a central module (11), whilst the corresponding mounts (16, 17), tie rods (18, 19), feet (20), and supports (20a) are mounted together in the form of two side modules (12, 13). A fast-clamping and fast-release system (21) is moreover provided for the stable but releasable connection between the said central module (11) and the said two side modules (12, 13).

Abstract: A vertical coil winder for winding hot rolled products. A reel includes a cylindrical container and a plurality of vertical rods provided within the container. A gap is defined between the container and the rods to receive a hot rolled product which is wound due to the rotation of the reel. The rods can move in the radial direction between an expanded position for winding the product and a withdrawn position for extracting the coil.
