摘要： A sheet decelerating and stopping apparatus which may be used as a staging apparatus in a sheet-feeding environment. A pivoting member having decelerating and stopping areas thereon is spring biased to an operating position in which the decelerating area on the member cooperates with a decelerating area on on wall of a sheet-feeding track in which the sheet is fed to decelerate the sheet. The stopping area on the member stops a sheet if it is not stopped by the cooperating decelerating areas. An actuator moves the member to an inoperative position to enable a sheet to be released from the apparatus.

摘要： A sheet feeding apparatus includes a retard mechanism to prevent the inadvertent feeding of doubled or overlapped sheets. The retard mechanism includes a plurality of belts in an assembly positioned adjacent to a sheet feeding roller, and rotating in such a direction as to retard the sheets being fed. The retard assembly is mounted on the free end of a lever arm pivotally secured adjacent to its other end to the base of the sheet feeding apparatus. The lever arm with the retard assembly mounted thereon is spring-urged toward the feed roller, but may be moved slightly away from said roller to accommodate the thickness of the sheet being fed between the feed roller and the retard assembly. A dual spring arrangement contained in the lever arm permits the lever arm to move with relatively little force to accommodate passage of a single sheet, but to resist more vigorously any additional movement, such as would be required for the passage of double or overlapped sheets. A one-way retaining device permits movement of the lever arm and retard assembly toward the feed rollers as the roller and belts wear, but prevents movement away from said roller except for the limited movement permitted to accommodate sheets during feeding. The retaining device may be released to permit the lever arm and retard assembly to be swung away from the feed roller for replacement of the feed roller and retard belts when worn.

摘要翻译： 片材进给装置包括防止双重或重叠片材的无意中进给的延迟机构。 延迟机构包括位于片材进给辊附近的组件中的多个带子，并沿着延迟供给的片材的方向旋转。 延迟组件安装在杠杆臂的自由端上，杠杆臂相对于其另一端可枢转地固定到片材进给装置的基部。 安装有延迟组件的杠杆臂被弹簧推向进给辊，但是可以稍微远离所述辊移动以适应在进给辊和延迟组件之间供给的片材的厚度。 包含在杠杆臂中的双弹簧布置允许杠杆臂以相对较小的力移动以适应单个片材的通过，但是更有力地抵抗任何额外的运动，例如通过双重或重叠片材所需的任何附加运动。 当辊和皮带磨损时，单向保持装置允许杠杆臂和延迟组件朝向进给辊移动，但是除了允许在进给期间容纳片材的有限运动之外，防止移动远离所述辊。 可以释放保持装置以允许杠杆臂和延迟组件摆脱进给辊，以便在穿着时更换进给辊和延迟带。

摘要： Apparatus for driving sheets comprises a track assembly, a first plurality of drive rollers and a cooperating set of back-up rollers for transporting sheets in a first direction along the track assembly, a second plurality of drive rollers and a cooperating set of back-up rollers for driving said sheets in a second direction with respect to the track assembly, into proper position to cause them to be transported by said first plurality of drive rollers and cooperating back-up rollers, and solenoid-operated actuating mechanism for simultaneously operating both sets of back-up rollers to cause one set of back-up rollers to be moved into operative position when the other set of back-up rollers is moved out of operative position.
