阅读说明：本技术 具有多个针板的针刺机或针刺线 (Needle machine or needle thread with a plurality of needle plates ) 是由 F·德曼奇 P-E·劳勃姆 于 2020-03-26 设计创作，主要内容包括：一种用于通过针刺加固纤维网、特别是无纺织物片材的针刺机,包括一系列针场板,每个板具有至少一个从该板的一个面,即针面突出的相应的针场；用于使纤维网在该系列板的针的前面运动的装置；以及用于使针在与该网的运动方向上横向的来回运动的装置,使得它们在一个方向然后在另一个方向上穿过在它们的前面经过的纤维网,该系列针场板至少包括第一板和第二板,该第一板包括第一针场,该第二板包括第二针场,该第一针场根据第一针面图案布置在该第一板的针面上,并且该第二针场根据第二针面图案布置在该第二板的针面上,其特征在于,该第一针面图案使得它不能通过相对于平行于该针的方向和/或该针的运动方向的轴线旋转180°而叠加在其图像上,并且第二针面图案与第一针面图案相同,但是相对于平行于针的方向和/或针的运动方向的轴线相对于第一针面图案旋转了180°。(A needle machine for consolidating fiber webs, in particular nonwoven fabric sheets, by needling, comprises a series of needle field plates, each plate having at least one respective needle field projecting from one face, i.e. the needle face, of the plate; means for moving the web in front of the needles of the series of plates; and means for moving the needles back and forth transversely to the direction of movement of the web, so that they pass through the web passing in front of them in one direction and then in the other, the series of needle field plates includes at least a first plate including a first needle field and a second plate including a second needle field, the first field of stitches being arranged on the needle side of the first plate according to a first needle side pattern and the second field of stitches being arranged on the needle side of the second plate according to a second needle side pattern, characterized in that the first needle pattern is such that it cannot be superimposed on its image by rotation through 180 DEG relative to an axis parallel to the direction of the needle and/or the direction of motion of the needle, and the second stitch pattern is identical to the first stitch pattern but rotated 180 deg. relative to the first stitch pattern with respect to an axis parallel to the direction of the needles and/or the direction of motion of the needles.)
