THREE-DIMENSIONAL MESH STRUCTURE, METHOD OF MAKING THREE-DIMENSIONAL MESH STRUCTURE AND DEVICE FOR MAKING THREE-DIMENSIONAL MESH STRUCTURE Russian patent published in 2016 - IPC D04H3/16 

FIELD: manufacturing technology.

SUBSTANCE: device for making 1 three-dimensional mesh structure according to present invention includes a nozzle 3 with multiple extrusion holes 31 to provide for extrusion and falling down thermoplastic synthetic polymer in molten state, which leads to formation of beam 21, consisting of a set of fibres 20; a pair of discharging chutes 42a, 42b and arranged across wide faces 22a and 22b beam fibres 21 forming inclined surfaces 44a and 44b, which are inclined in direction of beam fibres 21 and are arranged opposite each other at a distance S1, which is less than width of narrow side of mass extrusion holes 31; hole 5 for supply of cooling water on inclined surfaces 44a and 44b; and two exhaust mechanisms 6 with endless bands 61a and 61b entering in contact with wide faces 22a and 22b beam fibres 21, stretching fibre bundle 21, and located opposite each other at a distance less than distance between a pair of discharge chute 42a and 42b.

EFFECT: device for making a three-dimensional mesh structure, which enables easy adjustment of elasticity (repulsion) and accuracy of dimensions at low costs.
