    • Through operation of a driving crank, the knotting apparatus is advanced over the canvas holder, on the one hand, and the various tools for the knotting operation are actuated, on the other hand. By means of drawing tongs (95) comprising two gripping arms (74, 92) the yarn (94) is pulled into the region of a needle head (103). With the front ends of two snaring arms (78,79) a cut-off piece of yarn is hung over the needle head (103). By means of two cross-arms guided parallel to the needle head, the ends of the piece of yarn are led through an aperture in the needle pushed through the canvas, whereupon the needle is retracted in order to form the knot. The desired color can be selected by means of a color selector (14). The method and apparatus make it possible to knot yarn (94) of selectively different colors rapidly and uniformly to the canvas.
    • 另一方面,通过驱动曲柄的操作,打结装置一方面推进到帆布保持架上,另一方面,用于打结操作的各种工具被致动。 通过包括两个夹持臂(74,92)的拉钳(95)将纱线(94)拉入针头(103)的区域。 在两个牵引臂(78,79)的前端处,一根切断的纱线悬挂在针头(103)上。 通过平行于针头引导的两个十字臂,将纱线的端部引导通过穿过画布的针中的孔,然后将针缩回以形成结。 所需颜色可以通过颜色选择器(14)来选择。 该方法和装置使得可以将选择性不同颜色的纱线(94)快速且均匀地结束到帆布。
