    • An apparatus for thermally splicing a plurality of associated pairs of yarn ends employed in tufting carpet is provided, having an electrically conductive wire extending across a width of a beam of yarn ends as a heating element, the wire being biased in tension between a pair of springs attached to the wire and to terminal mounted on a bracket member. A yarn end spacing and gaging bar is also mounted to the bracket to retain the associated pairs of yarn ends in a contacting relation in recesses disposed between teeth on the bar, the pairs of yarn ends being made up of yarn ends severed from a spent beam of yarn and associated yarn ends from a fresh beam of yarn. The apparatus maintains the heating element in a substantially fixed position with respect to the plurality of associated pairs of yarn ends to effect a substantially simultaneous heating and melting together of the pairs of yarn ends, and is preferably removably mounted to a beam rack holding the fresh beam.
    • 提供了一种用于在拼接地毯中采用多个相关联的纱线端对进行热拼接的装置,其具有延伸穿过纱线端部的宽度的导电丝线作为加热元件,该线材在一对 连接在导线上的弹簧和安装在支架构件上的端子。 纱线端部间隔和测量杆也安装到支架上,以将相关联的纱线端对保持在设置在杆上的齿之间的凹部中的接触关系中,所述纱线端部由从用过的束 纱线和相关纱线从新鲜的纱线束尾。 该装置将加热元件相对于多个相关联的纱线对保持在基本上固定的位置,以实现纱线端部对的基本上同时加热和熔化,并且优选地可移除地安装到保持新鲜的 光束。
