Abstract

Calender arrangement, especially for the manufacture of synthetic materials, with two support cylinders at the introduction end or at the outlet end, with three smaller diameter working cylinders arranged between these two support cylinders that can be operated and heated, characterized by the fact that the diameter of the intermediate working cylinder (4) of the three working cylinders (3 to 5) is equal to or only slightly less than the diameter of the two support cylinders (1, 2).
