    • The striking device described comprises a stringing system in the form of individual strings. The latter are maintained respectively in the frame of the striking device (5) by means of rivet sleeves (7), the heads (8) of the rivets being located against the external edges (9) of the holes. An advantageous feature is that in the event of breakage of a string, no effect is suffered by the adjacent strings, and only the broken string needs to be changed. The strings intended for first stringing or for replacement are provided with a permanently-fixed rivet sleeve. Furthermore, a free sleeve is provided in order to push and fit, after insertion, the string in the facing holes. Furthermore, a description is given of a stringing device (13), of simple design and by means of which even the inexperienced can replace the strings without difficulty.
    • 所描述的打击装置包括单个琴弦形式的弦系。 后者通过铆钉套筒(7)分别保持在打击装置(5)的框架中,铆钉的头部(8)抵靠孔的外部边缘(9)定位。 一个有利的特征是,在串的破损的情况下,相邻的串不会产生任何影响,并且只需要改变断开的字符串。 用于首次穿线或更换的绳条设置有永久固定的铆钉套筒。 此外,提供了一个自由的套筒,以便在插入之后将该绳子推入和装配在相对的孔中。 此外,给出了简单设计的穿线装置(13)的描述,并且甚至没有经验的穿着装置也可以毫无困难地替换串。
