There is provided a construction which comprises: a printing plate receiving means that is arranged at a position remote from the periphery of a plate cylinder for supporting a printing plate lock-up hook portion in parallel to the axis of the plate cylinder and as capable of displacement in parallel to that axis; a receiving position determining means for positioning at a predetermined position of the printing plate receiving means the printing plate lock-up hook portion mounted thereon; and a stop position determining means for stopping the printing plate receiving means at a predetermined position relative to a side end surface of the plate cylinder. The invention enables a printing plate being locked up to be positioned with an extremely high precision, yet in a short period of time, corresponding to the position where it is to be locked up, relative to an axially displaced plate cylinder.

Printing plate support device and printing plate removably mounting

Printing plate support device and printing plate removal mounting

The present invention provides an angle-bar device for use in a rotary press, which aims at removing ink and paper debris, etc deposited on the whole peripheral surfaces of the angle-bars by rotating the angle-bars continuously so as to increase the tension on the paper web which is running around and between the angle-bars. This angle-bar device comprises: at least two pieces of angle-bars (1a; 1b) disposed rotatively on the upstream and downstream sides, respectively, of the direction of running of a paper web; driving means (2a ; 2b) each for rotatively driving each of the angle-bars; a start controlling means (3) connected operatively with the driving means and adapted to control the starting of the driving means. The device further comprises an operation controlling means (4) for detecting the operating condition of the rotary printing press, which is connected with the start controlling means (3) so that it can send out output signal to the start controlling means. Each of the driving means (2a ; 2b) drives each of the upstream and downstream angle-bars at a preset rotational speed and in a preset direction of rotation.
