    • Twin compartment packets, e.g. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.
    • 双室隔间包,例如 茶包形成,隔间连接在包头和可选的尾部。 分组由一对分隔的管状腹板产生,所述隔板的管状腹板与隔室对准地配合在一起,然后腹板在隔室端部密封件处互连,并在那些密封件处切断以形成分开的包装。 用于进行处理的装置在将它们形成管状分隔的纤维网之前以间隔的间隔将剂量的茶沉积到两个分开的幅材上,使得两个幅材的隔室成为对准,互连注册隔间,并将互连隔间分隔成单独的包,同时 纸幅连续地穿过设备。 该方法能够高生产率,因为幅材能够以均匀的速度移动通过连续的阶段。

    • A sensor for detecting open longitudinal seams in the continuous wrapper of cigarette or cigarette filter rod produced by a continuous rod-making machine relies on detection by a microphone (54) of disturbance caused by the defective seam to an air stream. The air stream is generated from a narrow slot (44) and normally follows a fixed, preferably flat, surface (40) closely adjacent to the longitudinal path of a rod (12). The surface (40) is part of a body (22) which contains the microphone (54) and connecting leads (56, 58), together with a passage (36) allowing sound to reach the microphone. Air is bled through a small bore (52) and through a further bore (30) containing a sound-insulating filter (66) to provide a purging air flow in the passage (36).
    • 用于检测由连续制棒机产生的香烟或香烟过滤棒的连续包装纸中的开放纵向接缝的传感器依赖于由缺陷接缝引起的空气流的麦克风(54)的检测。 空气流由窄槽(44)产生,并且通常沿着与杆(12)的纵向路径紧密相邻的固定的,优选平坦的表面(40)。 表面(40)是包含麦克风(54)和连接引线(56,58)的主体(22)的一部分,以及允许声音到达麦克风的通道(36)。 空气通过小孔(52)和通过包含隔音过滤器(66)的另一孔(30)排出,以在通道(36)中提供净化空气流。
