Method for controlling a laying head of a tire component with a simplified path

A method for controlling a laying head, said laying head being intended for laying at least one tire component by winding said tire component in turns on a receiving face of a core rotated about its central axis, said receiving face having, along said central axis, a predetermined profile, said method comprising:

• a step (a) of geometric characterization of the profile, during which the outline of the profile of the receiving face is provided and a first set of remarkable points, referred to as “geometric remarkable points” are isolated on this profile, these points being considered to be characteristic of the shape of said profile, and said geometric remarkable points are stored in the form of a set of path points referred to as the “path chart”,
• a step (b) of functional characterization of the profile, during which a plurality of functional zones is determined on the profile, each of which extends from a zone start point to a zone end point, and a laying law is associated with each of said functional zones, which laying law specifies conditions for laying the tire component in the functional zone in question, and said zone start points and said zone end points, forming a second set of remarkable points referred to as “functional remarkable points”, are inserted in the path chart,
• then a step (c) of meshing during which, with reference to a predetermined direction of travel of the profile, a series of equidistant virtual points, referred to as “potential guide points”, which delimit in pairs line segments all having an identical length, equal to a predetermined chosen value, referred to as the “unit resolution pitch”, are defined on the profile, from the first functional remarkable point, that is to say from the point at which the first functional zone begins, considered the origin, to the last functional remarkable point, that is to say to the point at which the last functional zone ends, and said potential guide points are inserted in the path chart,
• then a step (d) of simplification during which the size of the path chart is reduced by applying to the path chart one or more selection criteria in order to select at least some, and only some, of the potential guide points and geometric and functional remarkable points contained in the path chart, and by deleting the points not selected, in such a way as to obtain a simplified path chart, of reduced size, within which at least one of the segments which connect the successive selected points in pairs have a length strictly greater than the chosen unit resolution pitch.
