Abstract: A clamping device for thin flexible printing plates has a tensioning rail at the trailing wall of a wide longitudinal groove in the plate cylinder. The tensioning unit is mounted for axial and peripheral adjustment on a support of "L" cross-section having a first leg seated with respect to the bottom of the groove and a second leg presenting an upstanding reference surface interposed between the tensioning rail and the trailing wall of the groove. A set of tensioning springs recessed in the tensioning rail bear against the reference surface and apply peripheral tension to the plate. A spring detent latches the tensioning rail temporarily against the reference surface, overcoming the tensioning springs while the trailing edge of the plate is being gripped. The spring detent is mounted upon and movable with the support. Screws having a plurality of selectable holes anchor the support in a series of peripheral positions for accommodation of plates of different length. A plurality of jack screws threaded into the tensioning rail have tips which bear against the reference surface on the support for removing slack from the plate and for tensioning of the plate about the surface of the cylinder.

Abstract: A device for registering of sheets, received in an underlapped stream, upon a feed table. The feed table has a retractable front stop and a side guide defining a condition of accurate register for the sheet. Cooperating with the side guide is a wiping mechanism which includes a lower wiping member and a cooperating upper wiping member for engaging a sheet between them for wiping the same into laterally registered position. A pre-gripper grips the leading edge of a registered leading sheet for transporting it forwardly and upwardly to a receiving cylinder thereby forming a wedged-shaped gap above the following sheet. Upon formation of the gap the upper wiping member is momentarily inserted into the gap in active wiping position, with the result that the following sheet is fully registered while it is still partially covered by the leading sheet. The front stop is mounted for swinging movement and so arranged that upon moving to active position it engages the underside of the leading sheet at a point spaced above the table thereby insuring the presence of a well-defined gap for entry by the upper wiping member. In one embodiment of the invention the upper wiping member is mounted upon a rotatable arm for moving the member quickly into and out of the gap while providing a limited amount of dwell in wiping position. In a second embodiment the upper wiping member is mounted upon an arm which reciprocates inwardly and outwardly of the gap.

Abstract translation: 用于将接收在被覆盖的流中的片材进行登记的装置放在进料台上。 进给台有一个伸缩式前挡块和一个侧向导轨，用于定义纸张的准确记录条件。 与侧导板配合的是擦拭机构，其包括下擦拭构件和配合的上擦拭构件，用于将片材粘合在它们之间以将其擦拭到横向配准的位置。 一个预夹具夹住一个已注册的导向片的前缘，将其向前和向上运送到一个接收圆筒，从而在随后的片材上方形成楔形的间隙。 在形成间隙时，上擦拭构件在主动擦拭位置瞬间插入到间隙中，结果是随后的片材完全登记，同时其仍被部分被前片覆盖。 前挡块被安装成摆动运动，并且布置成使得当移动到主动位置时，它在与桌子上方间隔开的点处接合前片的下侧，从而确保存在用于由上擦拭构件进入的良好限定的间隙。 在本发明的一个实施例中，上擦拭构件安装在可旋转臂上，用于将构件快速地移入和移出间隙，同时提供有限量的擦拭位置。 在第二实施例中，上擦拭构件安装在臂上，所述臂向内和向外间隙地往复运动。
