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

Abstract

The present invention refers to a method for controlling the laying 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.

Description

technical field [0001] The invention relates to a method for controlling the lay-up of tire components on forming rolls. [0002] The invention also relates to a device for controlling the laying down of tire components on forming rollers. Background technique [0003] Tires for vehicle wheels generally comprise a carcass structure comprising at least a carcass ply with respective opposing terminal edges joined to respective anchoring annular structures, commonly referred to as The “bead core”, placed in the area generally identified as the “bead”, the carcass ply has an inner diameter that roughly corresponds to the so-called “fitting diameter” of the tire on the respective mounted rim. The tire also comprises a crown structure comprising at least one belt layer placed in a radially external position with respect to the carcass ply and a tread band radially external with respect to the belt layer. A so-called "underlayer" may be inserted between the tread band and the bel...

Problems solved by technology

[0019] The Applicant has also observed that the operator has great difficulty manually managing the calibration parameters in a workshop where different components are prepared and laid up in parallel and thus have different machines / stations operating The machine / station has to be controlled and possibly calibrated, such as in a workshop of the type described in the aforementioned document WO2013 / 011396
