    Abstract: An electrical conductor element in the form of a flexible or rigid sheet is provided for detecting attempts to break into a space where valuables or money are being stored, such as a strongroom or the coin container of a slot machine. The base material of the element is in the form of a woven or non-woven material or of plastic sheeting, and the electrical conductor is in the form of wire such as enameled copper wire for electrical connection with an alarm system. The conductor is secured in place by stitching, that is to say the wire is either formed into penetrating stitches by being fed from the needle or shuttle of a sewing machine or it is fed from a stationary part of the sewing machine so as to be fixed in place by stitches or conventional textile yarn or thread. When the conductor is interrupted by drilling, sawing or the like the alarm system is activated.

    Abstract translation: 提供柔性或刚性片形式的电导体元件用于检测试图进入储存贵重物品或货币的空间的尝试,例如老虎机或老虎机的硬币容器。 元件的基材是织造或非织造材料或塑料薄片的形式,并且电导体是线材的形式,例如用于与报警系统电连接的漆包铜线。 导体通过缝合固定就位,也就是说,通过从缝纫机的针或梭子进给而将线形成为穿刺针迹,或者从缝纫机的固定部分进给,以便固定 通过针迹或常规纺织纱线或线程就位。 当导体通过钻孔,锯切等中断时,报警系统被激活。
