Abstract
A conveyor for conveying piece goods and the like through a helical path in a vertical direction has a frame and an endless conveyor belt supported by the frame having a conveying part guided in the helical path and a return path. The conveyor belt includes substantially rigid slats movably coupled near their axis and having an upper transport face. The slats are relatively pivotable around both of two axes. The frame has a helical support face for slidably supporting the slats in the conveying part and a radially directed guide face for guiding these slats substantially radially in the conveying part. At least a number of slats are provided with at least a guide roller rotatable about a substantially vertical axis of rotation and adapted to roll along the radially directed guide face.
