Apparatus and method for producing a base layer of a solid tyre

The invention relates to an apparatus and a method for producing a base layer of solid tyre blanks, consisting of a radially inner rubber subcore layer (4), a central core layer (5) and a radially outer covering layer (6). The apparatus has a pivot block (7) with two winding drums (8, 9), a winding system (10) for feeding and depositing the rubber subcore layer (4) and the covering layer (6) on the winding drum (8, 9), a laying unit (11) with a wire support (12) for feeding and depositing the core layer (4) on the winding drum (8, 9), wherein the pivot block (7) with the two winding drums (8, 9) is arranged between the winding system (10) and the laying device (11) in such a way that, in a first position, the first winding drum (8) is assigned to the winding system (10) and the second winding drum (9) is assigned to the laying unit (11), and wherein the pivot block (7); can be pivoted about an axis (13) in such a way that, in a second position, the first winding drum (8) is assigned to the wire support (12) a
