Abstract: A self-correcting conveyor facility has a conveyor belt for transporting flat objects, in particular mail items. The self-conveying correcting conveyor facility has an elastic conveyor belt for transporting flat objects, in particular mail items. The conveyor belt rests on a correction roller, which is supported in a rotatable manner in a roller support.

Abstract: A spiral winder wrinkle remover capable of wrapping a material of varying thickness into a structurally stable, smooth coil. As a material is supplied to the spiral winder, the collecting device, such as a spool, rotates and oscillates linearly along the axis of rotation to distribute the material along the length of the collecting device and form a structurally stable coil of material.
