Claims
- 1. A method for producing a package for use as a framework in the manufacturing of a body of composite material and which is formed by threads assembled by a multi-directional deposit of thread, said method comprising:
- depositing a single thread without residual tension in a sinuous path extending in a first direction and zig-zagging between end portions of rigid mutually parallel rods as to form a layer of said thread in a plane transverse to the direction of said rods;
- supporting the layer on a bearing surface;
- moving the bearing surface away from the region in which the thread is being deposited by about the thickness of the layer;
- compacting the layer along the rods with sliding of the layer by applying a pressure to the layer;
- depositing the single thread without residual tension in a sinuous path extending in a second direction and zig-zagging between end portions of the rigid mutually parallel rods so as to form a subsequent layer of said thread in a plane transverse to the direction of said rods, said second direction crossing said first direction so that said first-mentioned layer crosses said subsequent layer;
- supporting the subsequent and first-mentioned layers on the bearing surface;
- again moving the bearing surface away from the region in which the thread is being deposited by about the thickness of the subsequent layer;
- compacting the subsequent layer along the rods with sliding of the subsequent layer by applying a pressure to the subsequent layer; and
- repeating the steps of depositing, supporting, moving and compacting to form additional superimposed layers alternating in the first and second direction until a desired number of layers is formed.
- 2. A method according to claim 1, wherein the thread deposited without tension between said rigid mutually parallel rods is delivered by a mechanical thrust on demand in a direction substantially parallel to said direction of the rods.
- 3. A method according to claim 1, including carrying ends of said rigid mutually parallel rods which are opposite from said end portions thereof between which said thread is deposited for counteracting a force on said rods transmitted to said rods by said steps of compacting and through friction between said layers and said rods.
- 4. A method according to claim 3, including vibrating said carrying of said rods after each step of compacting for sliding said rods with respect to said layers.
