Lineshaft conveyors are a truly innovative design among powered conveyors. The basic design utilizes rollers that are driven by a urethane belt from a drive shaft under the roller bed which runs the length of the conveyor. This driveshaft is turned by a motor and transmits its rotation via small urethane belts to individual rollers.
This type of conveyor also provides a basic accumulation function. When back-pressure is applied to the product being conveyed, the spools driving the rollers under the product will slip on the drive shaft providing very minimal back-pressure.
