FUNCTION ON A CONVEYOR BELT
To enable a conveyor to manage belt tension, it can be fitted with an assembly known as a “tension group”. This take up pulley unit adjusts belt tension according to the load exerted by the conveyed material, as well as to the forces generated by stop/start operations.
This group of conveyor drums is made up of 2 bend pulley (or “deviation drums”) to deflect the belt from the drive drum to the take up pulley. The take up pulley then returns the belt to the 2nd bend pulley in the direction of the tail pulley.
The take up pulley is suspended in vacuum with an added load to increase its weight. It enables even tension to be applied to the conveyor, with the option of raising or lowering the belt according to belt load and applied forces.
Implementation
The bend pulleys and take up pulley are machined with a convex shape. This process maintains perfect centering of the conveyor belt.

Other classic drums
tail pulley
Usually positioned on the other side of the control section on a conveyor belt, this drum is used to return the control section to its original position.
head pulley
The head pulley is the drum that sets the conveyor belt in motion.
snub pulley
The snub pulley increases the belt’s contact surface with the nearest drum.
