Description

In contrast, FROM the known printing machines with a reamer printing roller carriage moving over the taler, using an eccentric for adjusting the onset of the reiber roller, in the proposed print print. In order to eliminate the deflection of the frame from the printing force, the carriage is equipped with rollers interacting with the taler on the opposite side of the reamer roller.

The drawing shows a schematic side view of the printing press. On the frame 7, which is the base of the machine, the thaler 2 is movably fixed. On the frame 7 connection, a trolley 3 with two rollers 4 is installed. Through the holes in the sides of the trolley 3, threaded studs 5, springs 6 are fitted, one end of the stud 5 is fastened with nut 7, and the second is screwed into the body of frame 8, in which eccentric shaft 9 is mounted. In the middle, two ball bearings 10 are mounted on shaft 9, and operating lever 77 is mounted on end of shaft 9. Arms 72 are hinged to frame 8 ball roller 7J mounted in ball bearings.

The roller roller 7J is guided under the Yu ball bearings so that the links 72 rest against the side walls of the frame S. The roller 7J, pressing the Yu ball bearings, lifts the frame 8, with the studs 5 and the springs 6 raising the cart J with the rollers 4, which are pressed against the taler 2.

When you rotate the working lever 77 ball bearings Yu, leaning on the reiber roller 13, will lift the eccentric shaft 9 and the frame S with the studs 5.

Springs 6, szhima, will put pressure on the cart 3 with rollers 4, which, in turn, will transmit pressure on the thaler 2 from the bottom up. Thus, the thaler 2 will be clamped on one side with a reiber roller 73, and on the other side with rollers 4.

A printing plate or lithographic stone 74 is placed on the thaler 2. The ink is moistened and rolled. A sheet of blank paper is placed on top of the paper.

75

a cardboard deckel 75 is applied. The reamer roller 13 is brought up to the stops under the W ball bearings, the operating lever 7 is turned and the entire printing mechanism is sharply pulled along the entire taler 2. Then the working lever and the reiber roller are returned to the initial position and the printing mechanism idles to roll back. Having thrown dekkel 15 for the printing mechanism, remove the finished print.

Subject invention

A printing machine with a carriage with a reamer printing roller moving over a taler, using an eccentric for adjusting the onset of a reiber roller, characterized in that, in order to eliminate the deflection of the frame from the printing force, the carriage is equipped with rollers 4 interacting with the thaler 2 on the opposite side of the reiber roller 13 .
