    • An apparatus for providing a continuous supply of web material to a web printer or other system. The web material is fed from a first roll supported in a feed position, and when the first roll is near depletion, the leading end of a second roll is adhesively connected to the web of the first roll with that web then being severed. One belt drive means is employed for rotating both the forward and rearward rolls so that these achieve the same speed for the connecting and severing operations. The belt drive means are connected to the press drive through control means which vary the belt drive speed in accordance with the tension of the web. An indexing conveyor supports forward and rearward rolls to locate the rolls in the forward and rearward running positions and in intermediate positions for connecting and severing of the web material and for loading of new rolls into the system.
    • 一种用于向网络打印机或其他系统提供连续供应网状材料的设备。 纤维网材料从支撑在进料位置的第一辊进料,当第一辊接近耗尽时,第二辊的前端与第一辊的纤维网粘合地连接,然后被切断。 采用一个带驱动装置来转动前辊和后辊,使得它们达到相同的连接和切断操作速度。 皮带驱动装置通过控制装置连接到压力传动装置,该装置根据卷材的张力改变皮带驱动速度。 分度传送器支撑向前和向后的辊以将辊定位在前后运行位置和中间位置,用于连接和切断卷材,并将新卷装载到系统中。
