Abstract:
A process for controlling the deposition of roving by winding or contact on large structures, in which the deposition is carried out onto a mandrel (1) driven in rotation about its axis (.theta.) by a support/drive device, with a deposition head (6) adjustable in position along at least one first rectilinear axis of displacement (X) parallel to the axis of rotation (.theta.) of the mandrel and a second rectilinear displacement axis (Y) orthogonal to said axis of the mandrel, comprisingusing as a master axis the axis of rotation (.theta.) of the mandrel (1) and making the other axes (X, Y, .beta., .gamma., 8, 9) subservient to said master axis,controlling the master axis (6) by speed orders according to a pre-established program, and,from a pre-established trajectory table (21) integrating the kinematic of the master axis and giving for each slave axis the values of orders corresponding to predetermined angular positions of the master axis, to make subservient the slave axes as a function of the angular position of the master axis, from the instantaneous angular position of the master axis (.theta.), by computing from said trajectory table (21), for each instantaneous position, the corresponding control values of each slave axis and by applying these orders to said slave axes.
