A method for the production of reinforced tube-shaped structures (1) of
rubber layers and reinforcement layers (2, 3) has the steps of:a)
applying a first rubber layer (2a) with a first extrusion unit (4a) onto
a series of sequential rigid cylindrical mandrels (5) which are coupled
to each other and which are driven at an advancement speed (v) in the
direction of an advancement axis (x);b) applying a first filament layer
at defined desired filament angles (.alpha..sub.1) referred to the
advancement axis (x) with a bobbin creel unit (10a) having means which
rotate about the advancing mandrels (5);c) applying atleast one further
rubber layer (2b) to the first filament layer utilizing at least one
additional extrusion unit (4b);d) continuously measuring the advancement
speed (v) of the mandrels (5);controlling the quantity, which is applied
via the first extrusion unit (4a), in dependence upon the measured
advancement speed (v) in order to obtain a defined desired thickness of
the first rubber layer (2a);f) controlling the rotational speed of the
first bobbin creel unit (10a) during the rotation about the mandrels (5)
in dependence upon the advancement speed (v) in order to obtain a
filament layer having a defined desired filament angle (.alpha..sub.1).
