摘要:
A permanent magnet consists of a rare earth element (RE) or a mixture thereof, cobalt, iron and a transition metal (TM) selected from the group consisting of chromium, manganese, titanium, tungsten, molybdenum, and mixtures thereof; wherein for each two moles of the rare earth elements there are 14-19 moles of all other elements.

摘要:
A jogger for lateral alignment of sheets in a sheet-delivering device of a sheet-processing machine, such as a printing machine, has displaceable diaphragm; resiliently yieldable member; and a pusher member connected with the diaphragm and the resiliently yieldable member so that upon displacement of the diaphragm in one direction, the pusher member first moves toward a sheet-delivery device against the force of the resiliently yieldable member and then tilts after contacting a sheet stack in the sheet-delivery device, wherein the diaphragm is elastic and pneumatically impingeable to perform the displacement, so that the pusher member automatically adjusts upon the sheet stack.

摘要:
A pick-up unit in a printed sheet transport device for a printing machine includes a gripper shaft, a number of grippers and a number of corresponding counter gripping members, and a traverse which encloses the gripper shaft and the grippers at three sides. The traverse has a front wall, an upper wall and a rear wall; the latter extends to a plane of transporting of the printed sheet at an acute angle and is formed with a projection which extends inwardly from the rear wall of the traverse.
摘要:
A sheet gripper for a sheet-displacing apparatus such as a rotary printing machine has a pair of gripper elements whose faces are engageable with each other to grip the edge of a sheet being printed. At least one of the gripper elements is formed at its respective face of a relatively soft elastomeric material from whose surface extend hard fibers which are otherwise imbedded in the soft elastomeric material. The material may be a thermoplastic synthetic resin reinforced with glass fibers.
