A corner conveyor unit (6), for use in transferring movement from a conveyor operating in the direction A to another conveyor operating in the direction B, includes a plurality of frusto conical rollers (10) mounted for rotation between inner and outer curved walls (12, 14). A device is provided to urge the outermost frusto conical rollers in a separative direction, maintaining tension on the conveyor belt 16. A device is provided to restrain the conveyor belt (16) against movement in a direction C inwardly of the corner unit, the device including a plurality of roller assemblies (18) disposed around the outer edge region of the belt (16), each roller assembly (18) having a pair of roller members (20) engaged with upper and lower trackways (22, 24). Each trackway has an upper part and a lower part b, against which the upper and lower roller member (20) of each pair engage. To facilitate belt changing, the trackway parts (22a, 24a) may be separated from the trackway parts (22b, 24b), allowing the roller assemblies (18) to pass between the trackway parts, allowing the conveyor belt to be drawn inwardly of the corner unit.
A conveyor corner unit comprising a conveyor (16) entrained around frusto conical rollers (10), the belt being restrained against movements in a direction inwardly of the corner by roller members (20) secured to an outer region of the belt acting against a trackway (22, 24) disposed inwardly of said outer region, characterised in that the trackway comprises trackway parts (22a, 22a, 22b, 24b) mounted for relative movement between operative positions and separated positions in which separated positions the conveyor belt (10) and the roller members (20) thereof may be moved inwardly between said separated trackway parts, and separating means (40, 46, 48) to effect movement of said parts from said operative positions to said separated positions, and from said separated positions to said operative positions.
