Abstract: In a conveying device with an endless conveyor belt, for the conveyance of products, the conveyor belt is adapted, over a part of its length, to follow a path comprising a number of superimposed, helically extending belt tiers. To this end, the conveyor belt comprises mutually articulated and interadjustable link means consisting of a bottom part and links disposed at the ends thereof and forming the two sides of the belt. The links on the two sides of the endless conveyor belt are formed as spacers whose upper edge portions are adapted to bear against the lower edge portions of the links, likewise formed as spacers, disposed on the two sides of the overlying tier of the endless conveyor belt in order that such an overlying belt tier be supported by the immediately underlying tier of the conveyor belt.
