[0002] DE 40 38 936 A1 relates to a slide needle for a warp knitting machine, in particular a stitch-bonding machine, comprising an asymmetric needle head and a tip, which is arranged on the needle head above the central longitudinal axis of the needle, the needle head comprising a lower and an upper wedge surface, the lower wedge surface being oriented obliquely from the needle tip to the needle back and the needle head adjoining a thread cavity, a portion of the upper wedge surface extending parallel to the central longitudinal axis and facing the thread cavity, which portion serves as a guide surface for the front of the slide, furthermore, the thread cavity comprising a base, which lies significantly below the needle tip plane and is spaced apart from the lower wedge surface or the needle back by a small cross section. According to DE 40 38 936 A1, the oblique surface is arranged between the front end of the guide surface for the front of the slide and the needle tip, such that the needle tip is closer to the central longitudinal axis than the guide surface, the oblique surface and the guide surface are angled relative to each other by an angle DELTA, which is 3 to 10°, and the position of the needle tip has a relationship with the guide surface, because an imaginary line parallel to the guide surface and passing through the needle tip is at a small distance from the guide surface.

[0003] From EP 1 500 734 A1 a knitting needle is known, which is in particular for stitch-bonding technology, in particular for technical materials, comprising an elongated needle body comprising a recess for receiving a thread, holding means at one end, and a tip on the opposite side, and the needle body comprises two flat sides, which taper towards the tip at an acute angle opposite to each other, which acute angle has a first value at the tip, which first value changes to a smaller value at a transition point away from the tip. According to EP 1 500 734 A1, it is proposed that the needle body should comprise a needle upper side surface and a needle lower side surface, which intersect at the tip, the needle body should have a rectangular cross section, and the tip of the needle body should lie on a center line, which extends parallel to the longitudinal extension of the needle body and intersects the recess substantially at half the depth.

The needle can have a head shape with an elliptical cross section. The point cross section can be at least approximately elliptical in shape. For this purpose, the rungs can be designed relatively narrow. The rungs can also be referred to as cover surfaces. At least two cover edge chamfers can be provided. The cover edge chamfers can also be referred to as edge surfaces. The cover edge chamfers can extend over the entire point length. Furthermore, in a plan view, a stepped wedge shape can be created by at least one taper. Furthermore, the elliptical shape of the point can be provided not only in cross section, but also in side view and in plan view.

[0023] The invention improves the ability to absorb radial forces. Furthermore, wear on the needle and damage to the material to be processed is reduced. More planar circulation of the point is possible, and the nonwoven fabric / fiber can be better laid around the point. The improved circulation, without significant deflection, leads to the radial forces being absorbed more uniformly by the point. Furthermore, the smaller deflection reduces the punctual loading of the point and prevents the occurrence of wear notches. The contact surface of the needle is reduced, and a more uniform force distribution is created in the needle body. Further advantages can thus be achieved in terms of radial forces and axial forces.

[0033] Figure 1 is a detailed side view of a needle point 100 comprising a hook tip 102 and having an approximately oval cross section at the hook tip 102. Figure 2 is a plan view of the needle point 100.

[0034] The needle point 100 is intended for use in a stitch-bonding process. The needle point has a longitudinal axis 104, a vertical axis 106 and a transversal axis 108, which are arranged at right angles to each other.

[0035] The hook tip 102 forms a front portion of the needle point 100. The hook tip 102 comprises an upper surface 114, which is oriented in the direction of extension of the vertical axis 106 and extends along the longitudinal axis 104, side portions 116, 118, which are oriented in the direction of extension of the transversal axis 108, and a back portion 120, which is oriented in the direction of extension of the vertical axis 106 and forms a lower surface of the needle point 100. The hook tip 102 comprises a tip portion 122 and a hook portion 124. The tip portion 122 is positioned asymmetrically with respect to the longitudinal axis 104 and forms a front end of the needle point 100. The hook portion 124 adjoins the tip portion 122 in the direction of extension of the longitudinal axis 104. The hook portion 124 comprises a hook protrusion 126, a hook throat 128 and a hook base 130.

[0036] The needle point 100 comprises a shank 112. The shank 112 adjoins the hook tip 102 in the direction of extension of the longitudinal axis 104 and forms a middle or back portion of the needle point 100. The needle point 100 comprises a slit 132, which is arranged on the shank 112 and extends in the direction of extension of the longitudinal axis 104. The slit 132 serves to guide a slide in the direction of extension of the longitudinal axis 104 in order to open and / or close the hook throat 128.

[0037] The needle point 100 has an approximately oval cross section at the hook tip 102. Figure 3 is a cross-sectional view of the needle point 100 in a plane parallel to the vertical axis 106 and the transversal axis 108 at the hook base 130. Figure 4 is a side view of the needle point 100 as well as along Figure 4The cross-sectional view is taken along the line A-A, B-B, C-C, D-D and E-E, from which the cross-section at the corresponding position can be identified.

[0038] At positions C-C and D-D, the elliptical cross-section is clearly visible in the cross-sectional view. Towards the tip 122, the reduction of the cross-section in the vertical direction is greater than the reduction in the lateral direction. At the hook 124, the cross-section is delimited in the front by the hook base 130 and is semi-elliptical.

[0039] The cross-section is in the shape of an obtuse polygon, in this case a hendecahedron or a dodecahedron. On the longitudinal portion of the knitting needle 100, the corners of the cross-section form an edge which, on the upper side, extends parallel to the longitudinal axis 104 and, on the rear side, extends downwards from the tip 122 towards the hook 124 to the rear 120.

[0040] The knitting needle 100 comprises, on the upper surface 114 of the hook tip 102, a flat covering surface 134 extending along the longitudinal axis 104, a first inclined edge surface (e.g. 136) adjoining the covering surface 134, and a second inclined edge surface (e.g. 138) adjoining the first edge surface 136. The first edge surface 136 encloses an angle of approximately 90°. The second edge surface 138 encloses an angle of approximately 60°. The edge surfaces 136, 138 are arranged symmetrically with respect to the vertical axis.

[0041] At the rear 120 of the hook tip 102, the knitting needle 100 comprises a first edge surface (e.g. 140) adjoining the second edge surface 138, and a second inclined edge surface (e.g. 142) adjoining the first edge surface 140. At the rear 120, the first edge surface 140 encloses an angle of approximately 120°. At the rear 120, the second edge surface 142 encloses an angle of approximately 60°.

[0042] The upper edge surfaces 136, 138 comprise approximately 30% of the overall height of the knitting needle 100. The side portions 116, 118 comprise approximately 30% of the overall height of the knitting needle 100. The edge portions 140, 142 on the rear side comprise approximately 30% of the overall height of the knitting needle 100.

[0043] As is clearly seen in the plan view according to Figure 2 The side portions 116, 118 converge at the tip 122 in a stepped wedge-like manner, the side portions 116, 118 comprising a first step 144 and a second step 146. After the first step 144, the side portions 116, 118 converge at an angle of approximately 7°. After the second step 146, the side portions 116, 118 converge at an angle of approximately 25°.

[0044] Figure 5is a plan view of a needle 200 comprising a hook tip 202 and converging side portions 204, 206. The side portions 204, 206 of the needle 200 converge at a tip portion 208, thereby forming a polygonal oval shape 212 in the plan view. Furthermore, particular reference is made to Figures 1 to 4 and the related description.

[0045] Figure 6 is a side view of a needle 300 comprising a hook tip 302 and converging upper surface 304 and back portion 306. The upper surface 304 and back portion 306 converge at a tip portion 308, and optionally also at a hook portion 310, thereby forming an oval shape 312 in the side view. Furthermore, particular reference is made to Figures 1 to 4 and the related description.

[0046] The needles 100, 200, 300 are intended for use in a stitch-bonding process, wherein the needles 100, 200, 300 are additionally moved horizontally in a production direction transverse to the longitudinal direction of the needles during a vertical lifting movement along the longitudinal direction of the needles, corresponding to the direction of extension of the longitudinal axis.

[0047] Figure 7 The needle 400 is shown in use with a uniaxial nonwoven fabric 402, similar to the needles 100, 200, 300. The nonwoven fabric 402 comprises fibers (e.g. 406) extending at an angle of 90° to the feed direction 404. Figure 8 The needle 400 is shown in use with a biaxial nonwoven fabric 410. The nonwoven fabric 410 comprises fibers (such as 412, 414) extending at an angle of 90° with respect to each other, and at an angle of 45° with respect to the feed direction 404.

[0048] Due to the oval cross-section of the needle 400, the fibers 406 or 412, 414 of the nonwoven fabrics 402 and 410, respectively, loop around the hook tip 408 in a broad manner without significant deflection, in turn reducing wear on the needle 400 and damage to the nonwoven fabric 402 or 410.

[0049] The needle 400 can also be used with a multiaxial nonwoven fabric. Advantageous effects can in particular be shown in this case.

[0050] “Capable of” / “may” in particular refers to optional features of the present invention. Furthermore, there are also improvements and / or embodiments of the present invention which additionally or alternatively comprise one or more specific features.

[0051] If desired, separate features can also be taken from the combinations of features disclosed in the present case and used in combination with other features to limit the subject matter of the claims, while severing the structural and / or functional connection that can exist between the features.
