DEVICE FOR ADJUSTING A LAYER FRONT

摘要

The invention relates to a method for laying a reinforcing layer (1) on a receiving surface having an overall cylindrical shape, said layer including a leading edge (F) and a trailing edge (R) which, after complete rotation of the receiving surface, are intended to be arranged end-to-end between a maximum tolerance (Ts) and a minimum tolerance (Ti) measured relative to a reference front, during which: a layer of a given theoretical length is produced, the length separating the leading edge from the trailing edge is determined along a central measurement line (Lm), and along at least two lateral measurement lines (La, Lb) arranged transversely on either side of the central measurement line, said layer is deposited on a launching conveyor, the length correction (COR) to be made is determined at the central measurement line so that the two points (Af, Mm) of a front (F) of the layer, which correspond to the measured lengths the values of which are most distant from one another (Lmax, Lmin, La, Lm), are placed equidistant from the middle reference line situated at a distance (Tc) from the reference front, the value of which corresponds to the mean value of the maximum tolerance and the minimum tolerance, the leading edge of the layer is conveyed onto the receiving surface (6), and the remainder of the layer is deposited by adjusting the ratio of the longitudinal movement of the launching conveyor to the circumferential movement of the receiving surface, whereby the length laid down at the central line is equal to the length measured at said central measurement line (Lm) corrected by said length correction (COR).
