Description

[Technical Field]

[0001] The present invention relates to a knitting needle having a hook tip with a top surface, a side portion, and a back portion. [Background technology]

[0002] Document DE 40 38 936 A1 relates to a compound needle for chain sewing machines, particularly stitch bonding machines, with an asymmetrical needle head and a point on the head above the central longitudinal axis of the needle. The needle head includes lower and upper wedge surfaces oriented obliquely from the tip of the needle to the back of the needle, and the upper wedge surface, adjacent to the thread space and running parallel to the central longitudinal axis, with a section facing the thread space, serves as a front guide surface for the slide. The thread space also has a base located significantly below the needle tip level and separated from the lower wedge surface or the back of the needle by a small cross section. According to document DE 40 38 936 A1, the inclined surface is located between the front end of the front guide surface of the slide and the needle tip. The inclined surface and the guide surface are at a delta angle (3 to 0°) with respect to each other so that the needle tip is closer to the central longitudinal axis than the guide surface, and the position of the needle tip is in relation to the guide surface such that an imaginary line running parallel to the guide surface and passing through the needle tip has a very small distance from the guide surface.

[0003] From document EP 1 500 734 A1, a knitting needle is known with an elongated needle body, particularly for stitch bonding, especially for technical textiles. The needle body has a recess at one end for receiving the thread and the retaining device, a pointed end at the other end, and two flat sides that converge towards each other at an acute angle. Here, the acute angle has an initial value following the end and changes to a lower value at the transition point away from the end. Document EP 1 500 734 A1 proposes that the needle body have a top surface and a bottom surface that intersect at the end with a rectangular cross section, and that the end of the needle body is on a centerline that runs parallel to the longitudinal extension of the needle body and intersects the recess essentially halfway through its depth. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to improve the knitting needles mentioned at the outset structurally and / or functionally. [Means for solving the problem]

[0005] This object is achieved with a knitting needle having the features of claim 1. Advantageous embodiments and / or developments are the subject of the dependent claims.

[0006] The knitting needle can be used in a stitch bonding process. The knitting needle can be a sewing needle. The knitting needle can be used in a warp knitting machine.

The edge surface may subtend an angle of about 80° to about 100° at the top, particularly about 90°, about 65° to about 85°, particularly about 75°, and / or about 50° to about 70°, particularly about 60°. The angle may be selected as a function of the dimension of the needle in the direction in which the transverse axis extends. The smaller the dimension of the needle in the direction in which the transverse axis extends, the smaller the angle that may be selected. The larger the needle dimension along the horizontal axis, the greater the selectable angle. The knitting needle can have a first beveled edge adjacent to the upper surface above the hook tip and a second beveled edge adjacent to the first edge. The first edge can subtend an angle of about 80° to about 100°, particularly about 90°, and the second edge can subtend an angle of about 50° to about 70°, particularly about 60°.

[0019] The knitting needles may have a total height at the tip of the hook. The total height may extend in the direction of a vertical axis. The upper end surface may have a proportion of about 20% to about 40%, particularly about 30%, of the total height. The side portions may have a proportion of about 20% to about 40%, particularly about 30%, of the total height. The edge surface of the back section may have a proportion of about 20% to about 40%, particularly about 30%, of the total height.

[0020] The side portions of the knitting needle can converge at the tip section and / or the hook projection. The side portions of the knitting needle can converge at the tip section and / or the hook projection in a viewing direction corresponding to the direction of the vertical axis range. The side portions of the knitting needle can converge in an elliptical, partially elliptical, or polygonal manner.

The lateral portions of the knitting needles can converge in the second step at an angle of about 20° to about 30°, in particular about 25°. The angle can be selected as a function of the dimension of the needle in the direction of the extension of the transverse axis. The smaller the dimension of the needle in the direction of the extension of the transverse axis, the smaller the angle that can be selected. The larger the dimension of the needle in the direction of the extension of the transverse axis, the larger the angle that can be selected.

[0021] The top and back sections can converge at the tip section and / or hook section. The side portions of the needle can converge at the tip section and / or hook projection in a viewing direction corresponding to the direction of the horizontal axis range.

The top and back sections can converge at the tip section and / or hook section into a step wedge shape.

[0022] The upper portion can run along the longitudinal axis. The upper surface can run along the longitudinal axis. The upper side can be located posterior to the longitudinal axis. The tip section can be on the longitudinal axis. The tip section can be asymmetric with respect to the longitudinal axis. The tip can be located primarily posterior to the longitudinal axis. The tip can be located at least substantially completely posterior to the longitudinal axis.

[0023] In summary, the present invention therefore provides, inter alia, a compound needle for chain stitch bonding machines, in particular with an optimized point. The needle can have a head shape with an elliptical cross section. The cross section of the pointed head can be approximately elliptical. For this purpose, the bridge (Steg) can be designed to be relatively narrow. The bridge is also called the top surface. At least two roof ramps can be provided. The roof ramps are also called edge surfaces. The roof ramps can extend over the entire length of the pointed head. Furthermore, at least one taper can be used in plan view to create a stepped wedge shape. The elliptical shape of the pointed head can be provided not only in cross section, but also in side view and plan view.

[0024] This invention increases the radial force absorption capacity. It also reduces needle wear and damage to the workpiece. It allows for a wider loop around the pointed head, allowing the non-crimp fabric (Gelege) / fiber to better encase the pointed head. Thanks to the improved loop without significant deflection, radial forces are absorbed more evenly by the pointed head. Furthermore, the smaller deflection reduces point loads on the pointed head, preventing wear notches from occurring. The needle surface is reduced, and forces are distributed more evenly over the needle body. This allows for further benefits in terms of radial and axial forces. [Brief explanation of the drawings]

[0026] Figure 1 shows in side view a detail of a knitting needle 100 having a hook tip 102 and a generally oval cross section at the hook tip 102. Figure 2 shows the knitting needle 100 in plan view.

[0027] The knitting needle 100 is used in a stitch bonding process and has a longitudinal axis 104, a vertical axis 106, and a transverse axis 108 oriented at right angles to one another.

[0028] The hook tip 102 forms the front of the knitting needle 100. The hook tip 102 is oriented within the vertical axis 106 and has a top surface 114 extending along the longitudinal axis 104, side sections 116, 118 oriented in the direction of extension of the transverse axis 108, and a back section 120 oriented in the direction of extension of the vertical axis 106 and forming the underside of the knitting needle 100. The hook tip 102 has a tip section 122 and a hook portion 124. The tip portion 122 is asymmetrical with respect to the longitudinal axis 104 and forms the front end of the knitting needle. The hook portion 124 has a hook protrusion 126, a hook throat 128, and a hook base 130.

[0029] The knitting needle 100 has a needle shaft 112. The needle shaft 112 is adjacent to the hook tip 102 in the direction of extension of the longitudinal axis 104 and forms a central portion or back section of the knitting needle 100. The knitting needle 100 has a slot 132 disposed on the needle shaft 112 and extending in the direction of extension of the longitudinal axis 104. The slot 132 is used to guide a slide in the direction of extension of the longitudinal axis 104 to open and close the hook groove 128.

[0030] The knitting needle 100 has a generally oval cross-section at the hook tip 102. Figure 3 shows the knitting needle 100 in a cross-sectional view of a plane on the hook base 130 parallel to the vertical axis 106 and the horizontal axis 108. Figure 4 shows the knitting needle 100 in a side view and a cross-sectional view along lines labeled AA, 8-8, CC, DD, and EE, from which the cross-sections at corresponding locations can be seen.

[0031] The elliptical cross section is clearly visible in the cross section at positions CC and DD. Towards the tip 122, the cross section decreases more in height than in the lateral direction. In the hook section 124, the cross section is bounded at the front by the hook base 130 and has a semi-elliptical shape.

[0032] The cross section is polygonal, in this case an eleven- or twelve-sided polygon, with obtuse angles. The corners of the cross section form edges on the longitudinal sections of the knitting needle 100, which start at the top parallel to the longitudinal axis 104, on the back section, from the tip section 122 to the hook section 124, and slope towards the back section 120.

[0033] The knitting needle 100 has a flat top surface 134 extending along the longitudinal axis 104 on the upper side 114 of the hook tip 102, a sloped first edge surface such as 136 adjacent the top surface 134, and a sloped second edge surface such as 138 adjacent the first edge surface 136. The first edge surface 136 subtends an angle of approximately 90°. The second edge surface 138 subtends an angle of approximately 60°. The edge surfaces 136, 138 are symmetrically disposed about a vertical axis.

[0034] Knitting needle 100 has a first edge surface, such as 140, that is immediately adjacent to one another on back section 120 of hook point 102, and a sloped second edge surface, such as 142, that is adjacent first edge surface 140. First edge surface 140 subtends an angle of approximately 120° on back section 120. Second edge surface 142 subtends an angle of approximately 60° on back section 120.

[0035] The upper edge surfaces 136, 138 make up approximately 30% of the overall height of the needle 100. The side sections 116, 118 make up approximately 30% of the overall height of the needle 100. The back section edge surfaces 140, 142 make up approximately 30% of the overall height of the needle 100.

[0036] 2, the side sections 116, 118 converge to the tip section 122 in the shape of a stepped wedge, with a first step 144 and a second step 146. From the first step 144, the side sections 116, 118 converge at an angle of approximately 7°. From the second step 146, the side sections 116, 118 converge at an angle of approximately 25°.

[0037] Figure 5 shows in plan view a knitting needle 200 having a hook tip 202 and converging sides 204, 206. The sides 204, 206 of the knitting needle 200 converge to a tip 208, resulting in a polygonal oval shape 212 in plan view. Again, reference is made particularly to Figures 1 through 4 and the associated description.

[0038] 6 shows a side view of a knitting needle 300 having a hook tip 302 and converging top surface 304 and back section 306. The top surface 304 and back section 306 converge at the tip section 308 and possibly also at the hook section 310, resulting in an oval shape 312 in the side view. Further, reference is made particularly to FIGS. 1 through 4 and the associated description.

[0039] The knitting needles 100, 200, 300 are used in a stitch bonding process in which the knitting needles 100, 200, 300 are further moved horizontally laterally in the production direction during a vertical stroke movement in the needle longitudinal direction corresponding to the extension direction of the longitudinal axis.

[0040] Figure 7 shows a knitting needle 400, such as knitting needles 100, 200, 300, when used with a unidirectional non-crimp fabric (Geelege) 402. The non-crimp fabric 402 has fibers such as 406 that run at a 90° angle relative to the feed direction 404. Figure 8 shows the knitting needle 400 when used with a biaxial non-crimp fabric 410. The non-crimp fabric 410 has fibers such as 412, 414 that run at a 90° angle relative to each other and a 45° angle relative to the feed direction 404.

[0041] The oval cross section of the knitting needle 400 allows the fibers 406 or 412, 414 of the non-crimp fabric 402 or 410 to loop around the hook tip 408 over a wide area without significant deflection, thereby reducing wear on the knitting needle 400 and damage to the non-crimp fabric 402 or 410.

[0042] The knitting needle 400 can also be used with multiaxial non-crimp fabrics, which may have beneficial effects, among other things.

[0043] "kann" specifically denotes any feature of the invention, and therefore there are developments and / or exemplary embodiments of the invention that additionally or alternatively have the respective feature.

[0044] Where necessary, isolated features from the combinations of features currently disclosed may be selected and used to delimit the subject matter of the claims and may be combined with other features to eliminate structural and / or functional relationships that may exist between the features.
