    • In at least one implementation, a method for forming openings for a stitched seam in a composite panel having an outer layer, and a substrate behind the outer layer includes providing a laser beam onto the substrate, with the laser beam forming an opening through the substrate but not through the outer layer, and moving at least one of the laser or the substrate relative to the other so that a new opening can be formed that is spaced from the already formed opening. Successive openings can be formed in desired locations around the panel to facilitate subsequent panel stitching. In at least some implementations, the laser may form such openings while stitches are formed in the panel, wherein a stitch is provided in a previous opening while or nearly at the same time the laser forms a different opening for a subsequent stitch.
    • 在至少一个实施方案中,用于在具有外层的复合面板中形成用于缝合缝的开口的方法和在外层后面的衬底包括在激光束上形成穿过衬底的开口 而不是通过外层,并且相对于另一个移动至少一个激光器或基板,使得可以形成与已经形成的开口间隔开的新的开口。 可以在面板周围的期望位置形成连续的开口,以便于随后的面板拼接。 在至少一些实施方案中,激光器可以形成这样的开口,同时在面板中形成线迹,其中在先前的开口中设置线圈,或者几乎同时激光形成用于随后的针迹的不同的开口。

    • A device for producing a composite sandwich structure (1), wherein the sandwich structure comprises at least a first and second face sheets (2, 3) of a fibrous reinforcing material sandwiching between them a sheet of a core material (4), the device comprising a connecting fibre inserting apparatus for connecting the first face sheet (1), the core material (4) and the second face sheet (3) by means of connecting fibres (6). The connecting fibre inserting device comprises at least one needle bar extending transversally in the moving direction of the sandwich structure (1) and provided to exert a reciprocating movement in height direction of the sandwich structure (1). The needle bar comprises a plurality of spaced apart needles (11), arranged to face the first face sheet (2), and provided to take along a length of connecting fibre yarn (6) when reciprocating in and out of the sandwich structure (1) thereby forming a loop at the lower surface of the second face sheet (3). The connecting fibre inserting device also comprises at least one looper (12) arranged on a side facing the second face sheet (3) provided to co-operate with at least one needle (11) for seizing the loop of connecting fibre (6), and wherein the movement of the looper (12) is driven by a driving device which is provided to drive the movement of the looper (12) independently of the needle bar.
    • 一种复合夹层结构(1)的制造装置,其特征在于,所述夹层结构至少包括纤维增强材料的第一和第二面板(2,3),所述纤维增强材料在其间夹着芯材(4)片,所述装置 包括用于通过连接纤维(6)连接第一面片(1),芯材(4)和第二面片(3)的连接纤维插入装置。 连接纤维插入装置包括在夹层结构(1)的移动方向上横向延伸的至少一个针杆,并设置成在夹层结构(1)的高度方向上进行往复运动。 所述针杆包括多个间隔开的针(11),所述多个间隔开的针布置成面对所述第一面片(2),并且设置成当沿着所述夹层结构(1)往复运动时沿着连接纤维纱线(6)的长度方向 ),从而在第二面板(3)的下表面处形成环。 连接纤维插入装置还包括布置在面向第二面板(3)的一侧的至少一个弯针(12),其设置成与用于抓住连接纤维(6)的环的至少一个针(11)配合, 并且其中所述活套(12)的运动由驱动装置驱动,所述驱动装置被设置成独立于所述针杆驱动所述弯针(12)的运动。

    • An automatic chain-stitch sewing machine comprising, a sewing needle, a work holder for retaining a work piece during sewing, and a rotary hook having a hook point for capturing a needle thread loop and drawing the loop through a previous thread loop. The machine has means for spreading the limbs of the previous thread loop, and memory means having a plurality of instructions containing at least directional information designating the direction of movement of the work holder along separate coordinate directions in a plane relative the needle. The machine has means for reading the instructions and for forming electrical signals representing the instructions. The machine also has driving means responsive to the signals for moving the work holder in said plane relative the needle to form a pattern of chain-stitches in the work piece.
    • 一种自动链式缝纫机,其特征在于,包括缝纫针,用于在缝制期间保持工件的工件保持架,以及具有用于捕获针线圈的钩点并通过先前的线环拉出环的旋转钩。 机器具有用于扩展以前螺纹环的四肢的装置,以及具有多个指令的存储装置,所述指令至少包含方向信息,该方向信息指定工件夹持器沿相对于针的平面中的分离坐标方向的运动方向。 机器具有用于读取指令和形成表示指令的电信号的装置。 机器还具有响应于用于相对于针移动所述平面中的工件保持件的信号的驱动装置,以在工件中形成链式线迹的图案。
