摘要： A throw-on and throw-off device for a blanket cylinder in the printing unit of an offset press is provided wherein two parallel double-acting fluid pressure cylinders connected to the blanket cylinder via a toggle-like linkage can be individually supplied with compressed air either consecutively or simultaneously so that, in the first case, precise sequential throw-on of the blanket cylinder on the plate cylinder and subsequently on the impression cylinder can be achieved and, in the latter case, there can be a very rapid throw-off of the blanket cylinder from both the impression cylinder and the plate cylinder. Compressed air energization of the two pressure cylinders is triggered by a control unit in accordance with the position of grip edge zones of the blanket, plate and impression cylinders being in registration. In order to ensure that throwing on and throwing off take place when the grip edge zones of the printing cylinders are positioned immediately opposite one another, the control unit detects the position of the printing unit cylinders relative to one another by way of an angular position sensor and also detects the actual speed of the press via a speed sensor. The control unit forms speed-dependent throw-on and throw-off actuating times which are advanced in the direction of rotation of the printing unit cylinders so that the reaction time is outside the time slot for grip edge zone registration.
摘要翻译：提供了一种用于胶版印刷机的印刷单元中的橡皮布滚筒的抛出和抛出装置，其中两个平行的双作用流体压力缸通过肘式连杆连接到橡皮布滚筒上，可以单独地供应压缩空气连续或同时地，使得在第一种情况下，可以实现印版滚筒上的橡皮布滚筒和随后在压印滚筒上的精确连续喷涂，并且在后一种情况下，可以非常快速地抛出的压印滚筒和印版滚筒。两个压力缸的压缩空气通电由控制单元根据橡皮布，板和压印缸的夹紧边缘区域的位置而被触发。为了确保在打印滚筒的抓握边缘区域彼此相对定位时发生扔掉和丢弃，控制单元通过角位置传感器检测打印单元气缸相对于彼此的位置并且还通过速度传感器检测压机的实际速度。控制单元形成与打印单元滚筒旋转方向前进的速度相关的投掷和脱落致动时间，使得反应时间在握持边缘区域对准的时间段之外。

摘要： A sheet-conveying drum for use between units in a printing machine is provided with a plurality of gripper bridges arranged substantially circumferentially symmetrically on the drum surface. The gripper bridges hold the paper to the drum and include gripper impact strips that are adjustable radially relative to the drum in order to accommodate printing materials of different thickness. Each gripper impact strip is adjusted by means of a positioning device that is arranged on the drum radially inward of the gripper impact strip and mounted so that it can move axially relative to the drum and cam the gripper impact strip radially. The axial movement of each positioning device is brought about by an actuating device which is preferably a pneumatic cylinder and is disposed on the body of the drum at the free end of each positioning device. An energy supply sequentially actuates each actuating device resulting in the piston of each cylinder either extending or retracting. The extension and retraction of the actuating device moves the positioning device in the axial direction between adjustable stops thereby camming the gripper impact strips into two separate operating positions.

摘要： A device the for in-register transfer of sheets and for the conveyance thereof between the printing units of a multi-color press by means of gripper carriages that move on rails and which are driven by an endless chain and which are aligned on the delivery and feed cylinders by rotating drive forks and that cooperate with a cam roller carried by the carriage. For joint axial and radial alignment with quiet entry the drive fork has leading and trailing flanks of different thicknesses and the flanks are guided into engagement with the cam roller by hardened guide plates in the gripper carriage. The leading flank is undersized and the second flank has the dimension necessary for establishing proper registration of the carriage.

摘要： In a sheet-fed offset press having at least one printing unit in which the blanket cylinder can be thrown on and off the impression cylinder and plate cylinder by a pressure-medium-energized actuating arrangement, the pressure medium energization is triggered by a control unit in accordance with the position of grip edge zones of the cylinders being in registration. In order to ensure that throwing on and throwing off take place when the grip edge zones of the cylinders are positioned immediately opposite one another, the control unit detects the position of the printing unit cylinders relatively to one another by way of an angular position sensor and also detects the actual speed of the press via a speed sensor. The control unit forms speed-dependent throw-on and throw-off actuating times which are advanced in the direction of rotation of the printing unit cylinders so that the reaction time is outside the time slot for grip edge zone registration. The invention reduces the very substantial constructional outlay needed in the case of pressure-medium-energized actuating arrangements to ensure reliable throw-on and throw-off at high printing speeds.

Preferably spraying nozzles are provided for applying cleaning agents to the back side of the web of cleaning cloth, as well as control means for controlling the selective engagement of the pressing elements and the stepwise advancement of the cleaning cloth. The control means is arranged to selectively control the engagement of the pressing elements either individually or collectively, as desired and the clean web may be presented to the successive cylinders in either wet or dry condition. Optionally, a pressing element may also be employed to urge the cleaning cloth into engagement with the impression cylinder of the printing press.

摘要： A sheet-conveying drum for skew register correction in multicolor printing that does not affect the drive in sheet-fed rotary presses. The sheet-conveying drum comprises gripper bars and support or carrying webs that are disposed on a drum shaft. The web disposed nearest the drive input has on its flange an arcuate bearing surface around which the drum body can be skewed relatively to the drum shaft. The web disposed opposite the drive input is coupled to an adjusting eccentric bushing by way of a flange to cause the drum to skew. The movements of drum skewing do not adversely affect the drive and, therefore, the transmission ratios of the sheet-guiding cylinders relative to one another.

摘要： A throw-on and throw-off device for a blanket cylinder in the printing unit of an offset press is provided wherein the blanket cylinder is mounted at both its ends in eccentric bushings and the pivoting throw-on/throw-off movement of the bushings is produced by a toggle-like linkage. Two parallel double-acting fluid pressure cylinders are connected by way of their piston rods to a cross link which is pivoted to one of the links of the toggle linkage. The two pressure cylinders can be individually supplied with compressed air either consecutively or simultaneously so that, in the first case, precise sequential throw-on of the blanket cylinder on the plate cylinder and subsequently on the impression cylinder can be achieved and, in the latter case, there can be a very rapid throw-off of the blanket cylinder from both the impression cylinder and the plate cylinder.
