    Abstract: A pair of endless chains are reeved about spaced pairs of sprockets and transverse gripper bars are connected to the endless chain in spaced relation to each other. The sprockets are driven to propel the chains with transverse gripper bars secured therethrough through the cutter and creaser section, stripping section and delivery section of the press unit. The gripper bars have a plurality of gripper members secured thereto and extending rearwardly therefrom. The gripper members include a rigid base or pad member extending rearwardly from the gripper bar and a resilient sheet engaging gripper finger positioned in overlying relation with the fixed rearwardly extending rigid pad member. The gripper finger actuator includes vertical pin members extending upwardly through vertical portions in the transverse gripper bar with the upper edge portions abutting the underside of the resilient gripper fingers. The lower edge portions of the pin members have rollers thereon arranged parallel to the longitudinal axis of the transverse gripper bars. An elongated plate is slidably secured to the underside of the transverse gripper bars and has portions abutting the respective rollers connected to the vertical pins. The plate members have an inclined portion adjacent to the respective rollers so that axial movement of the plate member relative to the gripper bar moves the roller members along the inclined portions of the plate to move the resilient gripper finger end portions away from the fixed pad of the gripper member. The plate unit includes cam followers connected at one end to the transverse gripper bar and at the other end to the slidable plate. The cam followers are arranged to move the slidable plate longitudinally relative to the gripper bar to open the gripper members at preselected locations along the press unit.

    Abstract translation: 一对环形链条围绕间隔开的一对链轮被卷绕，并且横向夹杆连接到彼此间隔开的环形链条。 链轮被驱动以推动链条，横向夹持杆通过切割器和压头部分，剥离部分和压榨装置的输送部分固定穿过。 夹持杆具有固定到其上并从其向后延伸的多个夹持器构件。 夹持器构件包括从夹持杆向后延伸的刚性基部或垫构件，以及与固定的向后延伸的刚性垫构件的上部关系定位的弹性片接合夹爪。 夹持器手指致动器包括垂直销构件，其向上延伸穿过横向夹持器杆中的垂直部分，上边缘部分邻接弹性夹持器指状物的下侧。 销构件的下边缘部分具有平行于横向夹持杆的纵向轴线布置的辊。 细长板可滑动地固定到横向夹杆的下侧，并且具有邻接连接到垂直销的相应辊的部分。 板构件具有与相应辊相邻的倾斜部分，使得板构件相对于夹持杆的轴向运动沿着板的倾斜部分移动辊构件，以使弹性夹持器手指端部远离固定垫 夹具构件。 板单元包括一端连接到横向夹持杆的凸轮从动件，另一端连接到可滑动板。 凸轮从动件被布置成相对于夹持杆纵向地移动可滑动板，以沿着压榨单元在预选位置打开夹持构件。

    Abstract: Feed mechanism for stacking printed paper sheets. The sheets are carried from the press between pivotal grippers on an endless conveyor entrained over at least one pulley. A movable slide having a cam surface is provided adjacent to the conveyor to engage the grippers and open the same at a precise point over the stack. Means are provided to reciprocate the slide so as to adjust the position of opening. The slide is provided with an arcuate member at its forward end and a connecting link. The arcuate member is provided with a segmented recess to receive the connecting link. The cam surface is thereby directly continued by the link and the arcuate member which is received in the recess when the cam is shortened.
