Definitions
- the invention relates generally to needle machines for the production of nonwoven Fibrous materials and in particular to the needle boards used in such machines and their attachment to the needle bar of the needle machine. Needle machines are general known and for example in Lünenschand and Albrecht: “Nonwovens", Georg-Tiehme-Verlag Stuttgart, 1982, pp. 122-129.
- the needles used in such a machine point at their in a needle board held end a bend, the so-called crutch on. That with many hundreds of such Needles stocked needle board carries at his the needle bar of the needle machine facing Rear side of a polyamide plate, which in its adjacent to the needle bar surface having a plurality of grooves. In these grooves open the holes that the needles pick up the needle crutches each lie in the grooves and are during the stitch movement of the needle bar from the needle board facing contact surface of the needle bar supported against the stitching force.
- a first solution comprises U-shaped profile strips, which are the two longitudinal edges of Embrace needle bar and needle board together and pneumatically inflate Hoses, each between the needle bar and the overlying leg of the U-profile are biased so that they the needle board against the Press needle bar.
- a second solution provides, the needle board by means of several Bolt, the corresponding holes formed in a center line of the needle board holes penetrate, screw on the needle bar.
- An arrangement of the aforementioned types operates satisfactorily, as long as the width of the Needle boards and / or the movement speed of the needle bar and / or the Nadelgurzug devis, do not exceed certain limits. Due to the not insignificant Mass of staffed needle board and high acceleration forces tends that Needle board namely at the movement reversal of the needle bar in the return stroke, through the needles are pulled out of the processed fiber fleece, to an elastic Deformation, such that the needle board at the unconstrained places from the system on the needle bar and in the subsequent stroke reversal of the needle bar returns to the contact position on the needle bar.
- a needle board attached to both Edges is braced on the needle bar, so bulges in between the clamped Edge of the needle board elastically, and a needle board, which is bolted to the needle bar in its center line, lifts at its two longitudinal Edge from the needle bar elastic and then returns to the investment position back.
- the needle board flutters so on the needle bar.
- This elastic deformation is, for example, as will be shown later in detail, at a populated needle board made of aluminum of 10 mm thickness and about 305 mm width so great, that with a lifting height of the needle bar of 30 mm and a stitch frequency of 2,750 / min due to inertia forces in operation in the middle of the needle board a cyclically bulging and elastically resetting sink of about 1.4 mm results.
- This fluttering of the needle board on the needle bar not only creates unbearable Noise from the impact of the needle board on the needle bar in the elastic Reset, but is also dangerous, because the needle crutches loosen in their grooves and then the needles can move, thereby increasing the risk of damage Needles, needle board and needle bar is caused.

- alternative one can, together with a plane-parallel surfaces having needle board an intermediate layer body use that has a curvature and that between needle bar and needle board is placed and against which the needle board is stretched.
- Both types are easily retrofitted to all existing needle machines, and It is possible in this way, expensive, relatively thick needle boards made of carbon fiber reinforced Plastic through inexpensive, relative thin needle boards made of aluminum or similar To replace light metal alloys while taking advantage of the advantages of the invention without having to change anything at the needle machine
- a second type provides, the contact surface of the needle bar, against which the needle board is to be stretched, seen curved in cross section execute.
- the needle board can then have plane-parallel needle penetration surfaces.
- a needle bar, on which the needle board is to be tightened at its edges this means a convex curvature
- a needle bar, on which the needle board is arranged by means of its center plane Screws to be attached this means a concave curvature.
