Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides printed matter such as a calendar, which automatically moves the calendar to be printed and automatically turns the pages when printing a calendar or other already bound papers. This invention relates to an automatic transfer and flipping method, and an apparatus therefor.

Conventionally, when printing a name such as a company name on a calendar, the calendar is usually already bound, so the worker's hands have to "turn over" each page one by one as the printing machine starts operating. A method is adopted in which printing progresses depending on the task. However, this "turning" work requires great skill, and if the work is done over a long period of time, a considerable amount of effort is required, which may lead to poor printing or injury.

The present invention was developed in view of the above-mentioned conventional circumstances, and aims to provide a method and apparatus for automating the manual "turning" process, as well as the loading, setting, and unloading of calendars and other printed matter. It is something.
