摘要:
The winding machine is intended for plastic, laminated, aluminum, paper and self-adhesive materials and comprises two winding shafts (10, 11) which are each provided with a direct-drive motor (13, 14) and which are mounted on a plate (15) that is rotationally supported with respect to a vertical wall (16a) of a framing (16). The plate (15) has associated guides (50, 51) and drive means for moving the motors (13, 14) and shafts (10, 11) linearly with respect to the plate (15). The second end of each winding shaft (10,11) is supported by a carriage (40, 41) that can move in guides (44, 45) provided on a wall (16b), each carriage (40, 41) including a clamp (42, 43) that holds the ends of the winding shafts (10, 11) in a horizontal plane during the formation of a reel on any of said winding shafts (10, 11) and as the reel is moved into an unloading position.

A pinch valve includes a valve body having a slot which is configured to allow a web of substrate material to pass therethrough. The valve body has a sealing surface which includes a first curved portion with a first radius of curvature. A dynamic seal element is configured to engage the valve body and includes a second curved portion having a second radius of curvature which is larger than the first radius of curvature. An actuator is operable to selectively bias the dynamic seal element into and out of engagement with the valve body so that when it is biased into engagement with the valve body the web of substrate material is engaged between the sealing surfaces of the dynamic seal element and the valve body. Also disclosed is a processing system which includes the pinch valve.

A paper feeding apparatus comprises a fluid-supply device; a connecting pipe communicating with the fluid-supply device; and a plurality of force units connecting to the connecting pipe, each force unit having a pressing wheel on one end thereof; wherein each pressing wheel operates in coordination with a paper feeding wheel for feeding paper. The force units output equal force according to the same hydraulic pressure so that the pressing wheels provide the same component force to the corresponding paper feeding wheel so as to improve the quality of paper feeding. Furthermore, a method for using the paper feeding apparatus is disclosed.

A web winding up or unwinding device adapted for a web-form material coating machine comprises a web roll support, the web roll support comprising a web roll changing device, and a web edge guide device, the web edge guide device comprising a sensor device adapted for determining a shifting of a lateral edge of a web of the web-form material to be wound up on or unwound from the web roll arranged on the web roll support, a web roll support displacing device adapted for laterally displacing the web roll support, and a control device adapted for controlling the sensor device and the web roll support displacing device.
摘要:
A conveyor system for transporting a printing plate in a platemaking system, includes: a carriage riding on a track and one or more low friction substantially horizontal planar support surfaces provided as a high wear laminate, positioned above the carriage and the track, for supporting the printing plate on the non-emulsion side without the use of rollers, belts, bearings or air cushioning. The carriage includes one or more engagement mechanisms for engaging a bottom, non-emulsion side of the printing plate, and the track includes an air cylinder. The engagement mechanisms can be, for example, suctions cups which engage the plate by a vacuum, suction cups which engage the plate by pressure and adhesion, other adhesive devices, or a mechanical gripper for gripping the plate. The track or linear actuating system is preferably an air cylinder. Alternatively the linear actuating system could include a belt and pulleys, a chain and gears, or a threaded lead screw.

A device for registering the position of a rotor part in a transport system also having a static part in addition to the rotor part includes a dimensional standard forming part of the rotor part, and a plurality of transmitters provided on the static part; and a printing unit and a printing machine including the position registering device.
摘要:
A method for winding sheet material from a assisting roller onto a roll includes the step of exerting a compensating force in a compensating force direction on a shaft of the roll. The compensating force at least partially counteracts a bending stress in the shaft due to a gravitational force from the roll and/or a contact force from the source roll. The shaft includes two ends that are disposed to rotate on bearings. The bearings are spaced apart and disposed near the two ends. The space between the bearings defines a winding space of the roll. An apparatus for practicing the method is also disclosed.
