    • The present invention is directed to a sheet feeding apparatus and method. In particular this invention comprises a sheet feeding apparatus having a first conveyance member, a second conveyance member, and a sheet bending member. The first conveyance member conveys a sheet from a source of sheets at the first speed. The second conveyance member is positioned near the first conveyance member, and conveys the sheets away from the first conveyance member at a second speed that is less than the first speed of the first conveyance member. The sheet bending member is positioned to engage the sheet as the sheet moves from the first conveyance member to the second conveyance member. The sheet bending member engages the sheet to produce a gap between the tail end of the sheet and the second conveyance member. The lead edge of the next adjacent sheet from the first conveyance member is then fed into the gap. The apparatus also comprises a conveyance member for conveying a stream of overlapping sheets to the printing press. The conveyance member can have at least two portions pivotally connected to one another with at least one of the portions pivotally connected to the source of the stream of overlapping sheets. The conveyance member is constructed so that the portions can retract from the printing press in respect of pivotal connections.
    • 本发明涉及一种片材供给装置和方法。 具体地说,本发明包括具有第一传送部件,第二传送部件和片材弯曲部件的片材进给装置。 第一传送部件以第一速度从片材源传送片材。 第二传送构件位于第一传送构件附近,并且以小于第一传送构件的第一速度的第二速度传送片材离开第一传送构件。 片材弯曲构件定位成当片材从第一传送构件移动到第二传送构件时接合片材。 片材弯曲构件接合片材以在片材的尾端和第二传送构件之间产生间隙。 然后将来自第一传送构件的下一个相邻片材的前缘馈送到间隙中。 该设备还包括用于将重叠片材流输送到印刷机的输送构件。 传送构件可以具有至少两个枢转地彼此连接的部分,其中至少一个枢转地连接到重叠片材流的源。 传送构件构造成使得这些部分能够相对于枢转连接从印刷机收回。
