摘要:
A method of regulating the position of a clutch actuator in a vehicle employs the concept of adapting the servo-loop parameters of a position controller of the clutch to different operating conditions of the vehicle, as well as the concept of applying and continuously adapting a bias current of the actuator motor in order to avoid or minimize the incidence of a hunting or after-regulation behavior of the control loop and to thereby minimize the energy consumption of the actuator motor.

A flexible printing plate with bent suspension legs is secured on a cylinder of a printing press by utilization of a base body located in a cylinder groove. The base body supports flexible clamping elements which can engage the suspension legs. The base body may be formed by a plurality of short base bodies to facilitate removal and replacement of the base body.

There are provided plastisols based on poly(meth)acrylate which have a mean molecular weight in excess of 3,500,000 which have superior shelf life, tensile strength extensibility and viscosity as well as gel formation and filmforming propeties to those known heretofore. These plastisols are formed by emulsion polymerization.

An ink system of a rotary printing press includes a roller and a working doctor blade. The roller has a structured surface which may include helical or annular grooves.
摘要:
A method and apparatus for placement of a doctor blade bar against an ink dispensing roller utilizes doctor blade supporting base bodies which have resiliently supported doctor blades and which are shiftable between rest and work positions along doctor blade base support beams by blade base shifting devices. The doctor blades are moved into engagement with the screen roller along a curved path. The resilient support of the doctor blades eliminates blade warping and possible damage to the working edge of the blades.
摘要:
A short inking system for an offset web-fed rotary printing press utilizes a chambered doctor blade which contacts the lower periphery of the screen roller. A dampening system is situated interiorly of the plate cylinder. The axes of rotation of the screen cylinder and of the ink application cylinder are located on a first plane while the axes of the ink application cylinder and the plate cylinder are located on a second plane. The two planes intersect at the axis of rotation of the ink application cylinder and are inclined at an angle between 30.degree. and 60.degree. to the vertical.
摘要:
A printing ink feeding assembly for an anilox roller uses a plurality of individual anilox inking units. Each unit has its own individual chambered doctor blade, ink trough, ink pump and drive motor. The widths of the units and their positioning beneath the anilox roller are variable to provide flexibility of anilox roller inking.
摘要:
A chambered doctor blade utilizes parallel, axially extending spaced working and sealing doctor blades, together with spaced end plates to define an ink chamber. Free axial ends of the working doctor blade extend beyond the ends of the end plates and remove built-up ink beads. This removed ink flows down the surface of the inwardly inclined end plates.
摘要:
An ink transfer roller assembly which is usable to evaluate the smearing behavior of ink on a print carrier utilizes a central disk having a resilient oleophilic periphery and two side disks of smaller radii. The oleophilic surface is pressed against a freshly printed surface and is rolled off the printed area. Ink retained by the resilient roller is transferred to the previously uninked surface and is evaluated for ink smearing.
摘要:
A dampening system for a printing press uses a dampening fluid spray system to apply dampening fluid to a first of several serially arranged transfer rollers. The dampening fluid is carried by these transfer rollers to a dampening forme roller and then to a plate cylinder. The surfaces of the dampening forme roller and the several transfer rollers after the first such transfer roller are oleophilic. Spaced levers adjustably support several of the transfer rollers and the dampening forme roller.
