摘要该文的形成机构提供一个单页自动进纸机系统,重点是从堆栈纸中连续进给纸张。该机构包括安装在上部可绕轴旋转的上滚筒,下滚筒可转动地安装在平行于更低轴的一侧和上部轴下方,中间滚筒安装位于绕中间轴旋转并且平行上部轴和位于上部轴的下部和下部轴的上方。输送带送带延伸通过上部,中间和下部滚筒。因此,该机制包括用于驱动输送带,并且保持堆栈纸张放置于输送带在中间和上滚筒之间的部分。51515

而且该机构用于将纸张从输送带上的原位置运送到相对的位置。该机构包括安装在输送带上的一个可旋转的横梁,第一个扣环安装在横梁上,且在输送带上的横梁上至少悬挂一个可旋转的辊。第二个扣环也安装在横梁上,它的位置与第一个扣环至少相隔一个可旋转的辊的距离。该机构还包括用来调整横梁上扣环之间的间距的装置,以适应纸张的尺寸大小和运输时纸张间的间隙。

 Abstract In one form of a mechanism is provided in a sheet feed machine for stream feeding sheets from a stack with adjacent sheets fed in an overlapped configuration. The mechanism comprises an upper roller mounted for rotation about an upper axis, a lower roller mounted for rotation about a lower axis located parallel with and to one side of and below the upper axis, and an intermediate roller mounted for rotation about an intermediate axis located parallel with the upper axis and offset above a plane passing through the upper and lower axes. A conveyor belt extends over the upper, intermediate and lower rollers. The mechanism also includes means for driving the conveyor belt and means for holding sheets in a stack upon the belt be-tween the intermediate and lower rollers with a portion of the stack located above the belt between the intermediate and upper rollers. 

In another form of a mechanism is provided in a sheet feed machine for holding a stream of sheets moving atop a conveyor belt in position relative one to the other. The mechanism comprises a beam pivotably mounted above the conveyor belt, a first collar mounted to the beam, arid at least one roller rotatably suspended from the first collar over the belt. A second collar is mounted to the beam in spaced relation with the first collar and at least one other roller is suspended from the second collar. The mechanism also includes means for adjusting the spacing between the collars upon the beam to accommodate variations in feed sheet sizes and spacings of the sheets in the stream.
