Abstract (en)
A device for exerting a traction of a chain (2) getting out of a manufacturing machine, fit to be connected to the chain (2) to keep it in traction with its own weight. The device comprises a drive roller (3), motor means (5) for controlling the rotation of drive roller (3), a movable pushing roller (4), elastic means (9) for keeping pushing roller (4) pushed against drive roller (3) with the interposition of chain (2). As a consequence of the friction between chain (2) and rollers (3, 4), the device is steady with respect to the chain when drive roller (3) is blocked, whereas it slides up with respect to chain (2) when drive roller (3) is rotated by motor means (5). Sensor means are associated to motor means (5) for controlling the rotation of drive roller (3) as a function of the level of the device. <IMAGE>
