摘要： A leading edge of a leading blank in a series of overlapping envelope blanks is fed at a preselected speed into contact with a rotatably mounted backing roller. The backing roller is mounted in a frame and is selectively adjustable between a first position and a second position. A rotatably mounted segment roller is positioned opposite the backing roller. A pull-out segment is a secured to a radial portion of the backing roller. A plurality of longitudinal slots are provided in the surface of the pull-out segment and are selectively connected to a source of negative pressure. The segment roller is driven at a preselected speed greater than the speed of the series of overlapping blank. In a first mode of operation, the backing roller is adjusted to a first position in the frame so that upon rotation, the pull-out segment frictionally engages the leading edge of the leading blank, separating it from the series of overlapping blanks. In a second mode of operation the backing roller is adjusted to a second position so that the pull-out segment is removed from frictional engagement with the leading edge of the leading blank. Negative pressure is exerted through the longitudinal slots. Upon rotation of the segment roller, the negative pressure secures the leading edge of the leading blank to the pull-out segment separating the leading blank from the series of overlapping blanks.
摘要翻译：一系列重叠信封坯料中的前导坯料的前缘以预选速度进给，以与可旋转地安装的背衬辊接触。背衬辊安装在框架中并且可选地在第一位置和第二位置之间调节。可旋转地安装的分段辊定位成与支承辊相对。拉出段固定到支承辊的径向部分。多个纵向狭槽设置在拉出段的表面中并且选择性地连接到负压源。分段辊以比该系列重叠坯料的速度大的预选速度被驱动。在第一操作模式中，支撑辊被调节到框架中的第一位置，使得在旋转时，拉出部分摩擦地接合前导毛坯的前缘，将其与一系列重叠坯料分离。在第二操作模式中，将背衬辊调节到第二位置，使得拉出部分从与前导毛坯的前缘的摩擦接合中去除。负压通过纵向槽施加。在分段辊旋转时，负压将前导坯料的前缘固定到将前导坯料与一系列重叠坯料分开的拉出段。

摘要： A series of overlapping envelope blanks are fed into contact with a pull-out roll which engages and accelerates the first blank to separate it from the remaining blanks. From the pull-out roll, the separated blank is fed onto the surface of a rotary aligning wheel. A plurality of aligning pins extend from the surface of the wheel and are positioned in spaced relation around the wheel. The separated blank is fed into contact with the aligning pins forcing the blank with its trailing edge engaged with the pull-out segment to maintain the separated blank aligned on the surface of the wheel. Vacuum ports are positioned on the surface of the wheel adjacent to the aligning pins. The negative pressure from the vacuum ports secures the sheet to the surface of the wheel as the sheet is aligned into a preselected position on the wheel by contact with the pins. The wheel rotates at a lower speed than the pull-out segment and conveys the separated blanks in a radial path to a point on the aligning wheel where each blank is transferred to a folding mechanism where the seal flap of the blank is folded.
摘要翻译：一系列重叠的信封坯料被送入与拉出辊接触，该拉出辊接合并加速第一坯料以将其与剩余的坯料分离。从拉出辊中将分离的坯料送入旋转对准轮的表面。多个对准销从轮的表面延伸并围绕车轮定位成间隔的关系。分离的坯料被供给与对准销接触，迫使坯料的后缘与拉出段接合，以将分离的坯料保持在轮的表面上。真空端口位于与对准销相邻的轮的表面上。当真空端口通过与销的接触将片材对准到车轮上的预选位置时，来自真空端口的负压将片材固定到车轮的表面。轮以低于拉出段的速度旋转，并将分离的坯料以径向路径传送到对准轮上的点，其中每个坯料被转移到折叠机构，其中坯料的密封片折叠。

摘要： A continuous web of material is unwound from a roll by driven pull rolls that feed the web material to a printing unit in a feedline of an envelope making machine. The printing unit prints a selected one of the inside surface and the outside surface of the web before the web is cut and folded to form envelopes. The printing unit is supported by a base which is mounted for pivotal movement on a platform of a fixed frame member. The base is connected to the platform by a vertical pivot pin for movement through a 180.degree. between a first position for printing the inside surface of the web and a second position for printing the outside surface of the web. The base of the printer is locked to the platform in the selected one of the first and second positions to perform the desired printing operation. The web is fed between counter-rotating impression and plate cylinders rotatably mounted and driven on the printer base. A film of ink is transferred by an anilox roll on the printer base to the plate cylinder which transfers the inked image to either the inside or outside surface of the web. To reverse the printing to the opposite surface of the web, the printer base is unlocked from the platform and pivoted about the pivot pin to move the plate cylinder to the opposite side of the web. The base is then locked to the platform, and the printing operation is resumed. With this arrangement, a single printing unit is used to print both surfaces of the web material.
摘要翻译：通过将卷筒纸材料供给到信封制造机的进给线中的印刷单元的驱动拉辊，卷筒纸从卷筒展开。在幅材被切割和折叠以形成信封之前，打印单元打印幅材的内表面和外表面中的所选择的一个。印刷单元由安装成在固定框架构件的平台上枢转运动的基座支撑。基座通过垂直枢轴销连接到平台上，用于在用于打印幅材的内表面的第一位置和用于打印幅材的外表面的第二位置之间移动180°。打印机的基座在所选择的第一和第二位置中被锁定到平台以执行期望的打印操作。卷筒纸在可旋转地安装并在打印机基座上驱动的反向旋转印模和印版滚筒之间进给。油墨膜通过印刷机底座上的网纹辊转印到印版滚筒上，印版滚筒将油墨图像转印到幅材的内表面或外表面。为了将印刷反转到纸幅的相对表面，打印机基座从平台解锁并围绕枢转销枢转，以将印版滚筒移动到卷筒纸的相对侧。然后将基座锁定到平台，并恢复打印操作。利用这种布置，使用单个印刷单元来印刷网状材料的两个表面。
