    • A sheet inverter and stacking apparatus has at least one sheet inverter wheel having at least one arcuate sheet retaining slot into which a sheet may be inserted. The wheel is incrementally rotated from a sheet load position to a sheet unload position and a sheet is driven in the process direction into the slot when the inverter wheel is in the load position. The sheet is removed from the slot, stacked in a stacking tray and its leading edge registered. The sheet retaining slot provides minimal resistance to sheet movement in the slot upon insertion in the slot in the process direction and provides high resistance to sheet movement in the slot in a sideways direction transverse to the process direction.
    • 片材逆变器和堆垛装置具有至少一个片材变换轮,其具有至少一个弓形片保持槽,片可插入其中。 轮子从片材装载位置逐渐旋转到片材卸载位置,并且当变频器车轮处于装载位置时,片材沿着处理方向被驱动到槽中。 将纸张从插槽中取出,堆放在堆垛盘中,并将其前缘注册。 片材保持槽在沿着处理方向插入槽中时对槽中的片材移动提供了最小的阻力,并且在横向于过程方向的横向方向上提供了对槽中的片材移动的高抵抗力。

    • A method of tying a balloon having an inflatable bulb bounding a chamber, a flexible neck with a passageway in communication with the chamber, and a filling opening in the neck through which a fluid can be directed into the neck passageway and inflation chamber. The method contemplates the steps of providing a device with a housing having first and second elongate legs projecting therefrom in substantially parallel alignment, placing the neck of the balloon between the first and second legs, situating a length of flexible line across the neck in lengthwise alignment with and adjacent to one of the legs, twisting the legs about their length to thereby roll the balloon neck against itself and surround the line, and tying the line against itself so that the neck is embraced by the line. The invention is also concerned with a hand tool device for carrying out the method.
