Title: Sheet-fed rotary printing machine for perfecting
Inventor: LIEBERT OSKAR
IPC: B41F21/10
Filed: 1988-09-01
Abstract: In known sheet-fed rotary printing machines, a sheet is lifted from the first impression cylinder at its trailing edge by a suction gripper system arranged on a sheet transfer cylinder and is transferred to mechanical grippers likewise arranged on the sheet transfer cylinder, whereas the leading edge of the sheet is held on the first impression cylinder by a mechanical gripper system. Since the gearing which actuates the suction grippers is intended expressly to avoid a relative movement of the sheet, it is not possible to stretch out any folds or bulging which may occur. According to the invention, a circumferential component counter to the direction of rotation of the sheet transfer cylinder is imparted to the suction heads (14), arranged on the suction gripper system (11), during the return movement by the gearing (16, 18) driving them. As a result, the suction heads (14) slide along in the rear part of a sheet (8) in the direction of its trailing edge and make the sheet (8) taut before it is transferred to the mechanical gripper system. <IMAGE>

Patent DE-3939380-A1 (DE)
Inventor: BLATTNER JOACHIM
IPC: B23D51/14
Filed: 1989-11-29
Abstract: A wire saw comprises a cut length sawing wire (30), the two ends of which are fastened to two equal-sized cranks which rotate at the same speed, thereby imparting a reciprocating linear motion to the wire. The cranks are designed as the planet wheels (8, 18) of two planetary gears (28, 38). The two planetary gears (28, 38) are driven by sun wheels (1, 11) with which the planet wheels (8, 18) engage so that they rotate about their axis (9, 19) and roll around fixed ring-gears (6, 16), the pitch diameter of which is twice that of the planet wheels (8, 18). The length of the sawing wire (30) between the two securing pins (27, 37) is equal to the distance between the parallel median axes (29, 39) of the two planetary gears (28, 38). The two securing pins (27, 37) move along a line which intersects the two median axes (29, 39) at right angles to the latter. During sawing, the distance between the two securing pins (27, 37) varies only slightly, and therefore the sawing wire (30) is not subjected to any dynamic stress, but only to a static stress due to clamping.
