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 (Ri) on a first laying down structure () comprising a forming drum () and a first component (CI) of a tyre laid down on said forming drum (); detecting at least a first corresponding reflected radiation (Rr), determining as a function of said first reflected radiation (Rr) 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.

Method and apparatus for controlling the laying down of components of tyres on forming drums

A method for controlling the laying down of components of tyres on forming drums, includes: sending a first electromagnetic radiation on a first laying down structure including a forming drum and a first component of a tyre laid down on the forming drum; detecting at least a first corresponding reflected radiation, determining as a function of the first reflected radiation a first parameter representative of a first main length of the first component; comparing the first parameter with one or more pre-stored reference values; generating a first correction signal as a function of the comparison; and sending the first correction signal to at least one preparation station adapted to prepare the first component to regulate the preparation of further components. An apparatus for controlling the laying down of components of tyres on forming drums is also described.
