The invention relates to a calender (110) for profiling a rubber mixture for the manufacture of tyre covers, the calender (110) comprising three rotary rolls, the intermediate roll (114) and the lowerroll (116) being separated by a second distance (d1) in the vertical plane (PV1), which second distance (d1) defines the height of a second profiling nip (124), wherein the calender (110) is characterised in that it comprises a table (170), for detaching the profiled mixture, which is positioned downstream of the second profiling nip (124) and prevents the cohesion defects that result in cracks and fissures in the profiled member exiting the calender. 本发明涉及使用于制造轮胎外胎的橡胶混合物成型的压延机(110)，所述压延机(110)包括三个旋转辊，中间辊(114)和下辊(116)在竖直平面(PV1)中以第二距离(d1)分隔开，其中第二距离(d1)限定第二成型辊隙(124)的高度，其中压延机(110)的特征在于其包括用于将成型的混合物分离的工作台(170)，其设置在第二成型辊隙(124)的下游，并防止造成现有压延机中的成型构件中的裂缝和裂纹的内聚力缺陷。
