Apparatus for depositing slivers on double-curved bodies or surfaces

摘要

An apparatus for depositing uni-directional pre-impregnated slivers 12 on double-curved bodies or surfaces 23 provides essentially a dispensing reel 11 for the sliver 12, two jockey rollers 13 and 14, a warping roller 30 and a shaping roller 40 which co-operates with it, a guide roller 21 and a pressing roller 22 for pressing the sliver 12 onto the surface 23. By sub-dividing the warping roller 30 into a number of rotatable roller segments 31 and by the possibility of changing the shaping roller 30 to any desired contours of double-curved surfaces, it is possible to achieve a variable running length of the fibres over the width of the sliver 12 and a smooth application of the sliver to any double-curved surfaces without creases or undulations.
