摘要： A process for continuously producing an elastomeric composition is described comprising the step of dosing into at least one extruder (5, 20) at least one ingredient by means of a dosing device (3, 8a, 8b, 10a, 10b, 14, 24), wherein the dosing step is regulated on the basis of : i) actual weight values of the at least one ingredient measured at dosing instants of an evaluation time period of predetermined duration preceding a given dosing instant; ii) expected weight values of the at least one ingredient calculated for corresponding dosing instants of the evaluation time period of predetermined duration preceding the dosing instant; and iii) expected weight values of the at least one ingredient calculated for a prediction time period of predetermined duration following the dosing instant; so as to minimize: - a prediction weight error between actual weight values measured during the prediction time period and the expected weight values calculated for the prediction time period, and - a model weight error between actual weight values measured during the prediction time period and theoretical weight values of the at least one ingredient corresponding to the target weight loss of the at least one ingredient.

摘要： The present invention refers to a method for controlling the laying down of components of tyres on forming drums, said method comprising: sending a first electromagnetic radiation (Ril) on a first laying down structure (3a) comprising a forming drum (2) and a first component (CI) of a tyre laid down on said forming drum (2); detecting at least a first corresponding reflected radiation (Rrl), determining as a function of said first reflected radiation (Rrl) a first parameter (PI) representative of a first main length (LI) of said first component (CI); comparing said first parameter (PI) with one or more pre-stored reference values; generating a first correction signal (SI) as a function of said comparison; sending said first correction signal (SI) to at least one preparation station adapted to prepare said first component (CI) to regulate the preparation of further components. An apparatus for controlling the laying down of components of tyres on forming drums is also described.
