Rotary printing machine

Technical Field

The application relates to the field of printing, in particular to a rotary press.

Background

A rotary press is a press in which the image to be printed is bent around a cylinder. Printing can be performed on a variety of substrates, including paper, paperboard, and plastic. The substrate may be fed in a single sheet or may be unwound from a continuous roll by a printing press for printing and further modifications (e.g. die cutting, finishing, embossing) if desired. Printers using continuous rollers, sometimes referred to as "web presses," can print both front and back sides simultaneously at very fast printing speeds, and the printed sheets can be quickly dried and folded directly in different binding modes.

When the prior rotary printing machine is started up, the conveying roller is accelerated suddenly, the tension of a paper tape wound on the conveying roller is increased suddenly, the paper tape is not pre-tightened in advance, and the paper tape is easy to break in sudden tension change.

With respect to the related art in the above, it is considered that there is a drawback that the paper tape is easily broken without being tensioned.
