Abstract
The polygon effect in a double belt conveyor for the continuous production of laminates having a foam core foamed in situ between covering layers is avoided in that the slat belts are provided with guiding rails in the deflection areas, and in that the slat belts are driven by rotating pulling elements. The driving elements of the pulling elements engage on catches which are arranged along the slat belts, only in the sections of straight-line motion of the slat belts.
