Description

  The present invention relates to a calendar manufacturing method and a manufacturing apparatus thereof. Specifically, the present invention relates to a manufacturing method and a manufacturing apparatus for manufacturing a calendar having a hanging string.

  The wall-mounted calendar is obtained by binding a plurality of calendar papers (that is, calendar booklets) printed on a calendar for one year or in units of two months with a binding frame (header). In order to facilitate the recycling of the calendar and to save the trouble of sorting and collecting the calendar, the number of calendars using a paper binding frame is increasing recently. In a calendar using a paper binding frame, generally, a round suspension hole is formed in the binding frame, and the calendar is suspended through a nail or the like in the suspension hole.

  However, even though such a hanging hole can hang the calendar on a nail or the like, it cannot be hung on a wide or irregularly shaped hanging tool. Therefore, it is desirable to provide a hanging string (hereinafter referred to as a hanging string) also on a calendar using a paper binding frame. Therefore, the applicant of the present invention has filed a utility model registration application in which a hanging string is bonded to a calendar using a non-metallic binding frame, particularly a paper binding frame (actual application 2011-868).

  On the other hand, as a calendar manufacturing apparatus, those disclosed in Patent Document 1 and Patent Document 2 are known. These relate to a calendar manufacturing apparatus using a paper binding frame, but none of the manufacturing apparatuses can attach a hanging strap to the calendar. Therefore, if an attempt is made to manufacture a calendar with a string, the hanging string must be attached to the calendar using a special hanging tool as disclosed in Patent Document 3, which increases costs. Alternatively, there is no choice but to bond both ends of the hanging string to the outer surface of the binding frame by hand. Therefore, in any method, the linking process cannot be automated, and the manufacturing efficiency is inferior.
