<p>A method for producing a composite sandwich structure comprising at least a first and second face sheet of a fibrous reinforcing material sandwiching between them a sheet of a core material, the method comprising the steps of forwarding the multilayer object towards a connecting fibre inserting device and connecting the first and second face sheet and the core material together by inserting connecting reinforcing fibres. The sandwich structure is forwarded using a plurality of pulling devices, wherein a first and second clamping force is exerted by a first and second pulling device mounted at a position in front of behind the connecting fibre inserting device and wherein the first and second pulling devices in the clamping position is adjacent to the connecting fibre inserting device when inserting the connecting fibre; the pulling force by the first and the second pulling device to displace the multilayer unit being exerted simultaneously and being substantially equal in magnitude.</p> |
