ABSTRACT:
A process and apparatus for controlling the deposition of roving by winding or by contact on large structures, in which deposition is carried out on a mandrel (1) driven in rotation about its axis (.theta.). A deposition head (6) is adjustable in position along at least a first rectilinear axis (X) of movement parallel to the axis of rotation (.theta.) of the mandrel. The head (6) is also movable along a second axis of rectangular displacement (Y) orthogonal to the axis of the mandrel. The axis of rotation (.theta.) of the mandrel is taken as a master axis and the other axes (X, Y, .beta., .gamma., 8, 9) are made subservient to the master axis. The master axis (.theta.) is controlled by speed orders according to a pre-established program and from a pre-established trajectory table (21). The slave axes are made subservient as a function of the angular position of the master axis, from the instantaneous angular position of the master axis (.theta.), by computing from the trajectory table (21), for each instantaneous position, the corresponding order values for each slave axis and by applying these orders to these slave axes.
