摘要： A device for producing a composite sandwich structure (1), wherein the sandwich structure comprises at least a first and second face sheets (2, 3) of a fibrous reinforcing material sandwiching between them a sheet of a core material (4), the device comprising a connecting fibre inserting apparatus for connecting the first face sheet (1), the core material (4) and the second face sheet (3) by means of connecting fibres (6). The connecting fibre inserting device comprises at least one needle bar extending transversally in the moving direction of the sandwich structure (1) and provided to exert a reciprocating movement in height direction of the sandwich structure (1). The needle bar comprises a plurality of spaced apart needles (11), arranged to face the first face sheet (2), and provided to take along a length of connecting fibre yarn (6) when reciprocating in and out of the sandwich structure (1) thereby forming a loop at the lower surface of the second face sheet (3). The connecting fibre inserting device also comprises at least one looper (12) arranged on a side facing the second face sheet (3) provided to co-operate with at least one needle (11) for seizing the loop of connecting fibre (6), and wherein the movement of the looper (12) is driven by a driving device which is provided to drive the movement of the looper (12) independently of the needle bar.

摘要： Composite sandwich structure and method for producing such structure 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 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.
