    • Apparatus for changing the direction of transport of a sheet by about 75° to about 90° comprising: a first flat guide for contacting the leading edge of a sheet transported along a path to change its direction of transport by an acute angle; a second flat or concavely curved guide spaced from the first guide for contacting the leading edge of the sheet to change to direction of transport by an acute angle wherein the change of direction of transport of the sheet by the first and second guides totals about 75° to about 90°, the second concavely curved guide providing accumulation of the proper amount of sheet required to change the direction of transport of the sheet by the about 75° to about 90°.
    • 用于将片材的输送方向改变约75°至约90°的装置,包括:用于接触沿着路径传送的片材的前缘以使其运送方向改变锐角的第一平坦导向件; 与第一引导件间隔开的第二平坦或凹形弯曲的引导件,用于接触片材的前缘以改变输送方向锐角,其中第一和第二引导件的片材的输送方向的变化大约为75° 至约90°,第二凹形弯曲引导件提供将片材输送方向改变约75°至约90°所需的适量的片材的积聚。
