摘要： A feeder for paperboard blanks includes a transport, vertical relationship changing structure to alternately provide action and passive positions for the transport, a suction device, and a transmission with input and output shafts operatively connected so that the output shaft undergoes controlled acceleration during an initial portion of each revolution of the input shaft and is stationary during a last portion of each revolution of the input shaft, whereby the transport engages and grips a blank by static friction and moves and accelerates that blank to nip rolls without slippage occurring and so that each blank enters the nip rolls in register whereupon the blank is disengaged from the transport.

摘要： Apparatus for mounting a flexible printing plate comprises a printing cylinder having a surface upon which the printing plate is mountable, and a connection for applying subatmospheric pressure inside the cylinder. A plurality of valves selectively apply the subatmospheric pressure to the surface from inside the cylinder. These valves have depressable actuating members protrudable above the cylinder surface. Those actuating members contacted by the printing plate when applied to the cylinder surface are depressed thereby to effect application of subatmospheric pressure to beneath the printing plate to draw the plate against the cylinder. Preferably, grooves are provided in the cylinder surface for distribution of the subatmospheric pressure beneath the plate. Advantageously, the printing plate may have a thin, highly flexible and deformable fringe along its trailing edge to seal the surface grooves, at that location. This mounting arrangement facilitates quick changing of printing plates during printing operations.
摘要翻译：用于安装柔性印版的装置包括具有可安装印版的表面的印刷滚筒和用于在滚筒内施加低于大气压的连接。多个阀从气缸内部选择性地将低于大气压的压力施加到表面。这些阀具有可在气缸表面上方突出的可按压的致动构件。当压印在滚筒表面上时，由印版接触的那些致动构件被压下，从而在印版的下面施加低于大气压的压力，以使板抵靠气缸。优选地，在气缸表面中设置有凹槽，用于将低于大气压的压力分配在板下方。有利地，印版可以具有沿其后缘的薄的，高度柔性和可变形的边缘，以在该位置处密封表面凹槽。这种安装布置有助于在打印操作期间快速更换印版。

摘要： A method and an apparatus for stacking serially advancing parallel streams of blanks, such as corrugated paperboard blanks, by serially advancing such parallel streams in which there are spaces between pairs of such blanks in each of the streams but no spaces between the blanks of the pairs, creating spaces between the blanks of each pair during advance, stopping the advance of the blanks one after the other, and guiding succeeding spaced blanks one on top of the other to form a stack of blanks from each stream.
摘要翻译：一种方法和装置，用于通过串联地推进这种平行流中的串联进行的平行的坯料流，例如瓦楞纸板坯，其中在每个流中的这种坯料对之间存在空间，但是在对中的坯料之间没有空隙在提前期间在每对坯料之间产生间隙，一个接一个地停止坯料的前进，以及一个在另一个之上引导后续隔开的坯料，从每个流形成一堆坯料。
