Abstract
An apparatus for stacking sheets comprises a belt of predetermined length and an endless belt. The belts pass around fixed axis rollers and three guide rollers which are displaceable for the purpose of varying the belt geometry by means of a carriage. As soon as a sheet passes in one direction of movement into a transportation plane formed by the belts a drive displaces the carriage on a rail into a position above a stack in the same direction of movement, the sheet which is engaged by the belts being conveyed at double the speed of the carriage to one of the guide rollers around which it is rolled for deposit on to the stack.
