Date Jul. 16, 1987.A conveyor belt is adapted in endless design to follow, through a part of its length, a path comprising a number of superimposed, helically extending tiers. The conveyor belt consists of mutually articulated and relatively adjustable links, each comprising a bottom part and spacers arranged at the longitudinal edges of the bottom part, the spacers forming the two sides of the belt, the upper edge portions of the spacers being adapted to engage the lower edge portions of overlying tiers of the conveyor belt and fixedly connected through a part of their length to the longitudinal edges of the bottom part, the remaining part being movable relative to the bottom part. Each spacer is provided with shoulders mutually displaced in both the longitudinal direction and the lateral direction of the belt, to engage with both the inner side and the outer side of the an upper edge portion of the spacer of the underlying belt tier, thereby to positively guide the edge portion in the lateral direction. |
