摘要:
A mailroom conveyor system for transporting and handling a stream of printed and folded signatures supplied by high speed tapes of a folding apparatus of a printing press. The system includes a plurality of grippers, a rail system for guiding the grippers, an electric linear drive system for individually driving the grippers in the rail system, and a control system coupled to the electric linear drive system for individually controlling the movement of the grippers in the rail system.

A device for determining the height of a pile of sheets, includes a measuring sensor formed as an expansion member and pneumatically drivable towards a top surface of the sheet pile.
摘要:
A control circuit for an electric motor having a power control element containing a first semiconductor for driving the motor in one torque direction, and a power control element containing a second semiconductor for driving the motor in the other torque direction includes a circuit-breaker for at least isolating one of the power control elements, upon failure of the one power control element, and connecting the remainder of the circuit to the other power control element instead of the failed power control element.

An optical device for detecting a condition of a carbon brush in a drive unit includes lightguides disposed in vicinity with the carbon brush yet out of contact with the carbon brush and having a device for monitoring wear of the carbon brush, and a device for triggering a warning signal when the carbon brush has reached a predetermined residual length.
摘要:
A printing press and a method for controlling a printing press include rotatably mounted cylinders. At least two adjacent cylinders roll on one another through bearer rings. At least one of the adjacent cylinders can be rotated actively relative to at least one of the bearer rings by a setting device.
摘要:
A drive for a rotary printing press makes a reliable transmission of high torques possible and, with low structural expenditure, setting of the phase in the main drive gear train. In the drive for a rotary printing press, two adjacent transfer drums are mounted with shaft journals in side walls, a gearwheel of the gearwheel mechanism is disposed fixedly in terms of rotation on the shaft journals and the gearwheels are not in direct engagement with one another. The gearwheels of the adjacent transfer drums are permanently in engagement in each case with one intermediate gear. The gearwheels of the adjacent transfer drums and the intermediate gears are kept at a spacing from one another in each case with one lever. The intermediate gears are kept at a spacing in each case from one another with a coupler. The coupler can be disconnected and the engagement of the teeth of the intermediate gears can be canceled.
摘要:
An apparatus for depositing sheets onto a stack permits improved alignment of the sheets on the stack. At least one conveying element provides for cyclical forward movement of the sheets into a position above the stack. At least one reciprocating aligning element is provided for stacked sheets. A device for controlling movements of the aligning element includes a computer. At least one linear actuator moves the aligning element and may be controlled by the computer.
摘要:
A computer system and method is disclosed that analyzes and corrects retail data. The system and method includes several client workstations and one or more servers coupled together over a network. A database stores various data used by the system. A business logic server uses competitive and complementary fusion to analyze and correct some of the data sources stored in database server. The data fusion process itself is an iterative one—utilizing both competitive and complementary fusion methods. In competitive fusion, two or more data sources that provide overlapping attributes are compared against each other. More accurate/reliable sources are used to correct less accurate/reliable sources. In complementary fusion, relationships modeled where data sources overlap are projected to areas of the data framework in which fewer sources exist—enhancing the accuracy/reliability of those fewer sources even in the absence of the other sources upon which the models were based.
