Description of the Related Art Conventionally, as a calendar in which a plurality of paper sheets displaying calendars are bundled, the hanging upper end edge is covered with a metal fitting having a "U" cross section, and the metal fitting is used to display the date and the day of the week. It is well known that the sheet is wound and closed together with the end portion of the sheet.

However, in recent years, it has been required to improve the waste separation treatment, so that the conventional calender has such a trouble that it is troublesome to separate the metal fitting and the calender sheet.

Therefore, a heating adhesive is applied to the binding end portions of the paper sheets forming the calendar, and a plurality of sheets are stacked so that the binding end portions are aligned, and a plurality of sheets are heated and pressed. A calender making machine has been developed that adheres and closes the sheets.

This calender making machine is equipped with a table for carrying in the stacked sheets from one side, heating and pressurizing them, and then carrying them out from the other side. From one side to the other side of the table, an edge aligning device that aligns the peripheral edges of the laminated sheets and a latching opening at the binding edge of the laminated sheets whose peripheral edges are aligned by the edge aligning device are pressed. A punch device that opens, a perforation forming device that punches perforations for cutting a calendar at the binding end of the laminated sheet, and a heat press device that heats and presses the binding end of the laminated sheet (FIG. 10). (See) and are provided in order. On the table, there is slidably arranged a clamp device that grasps and moves the front end of the stacked sheets from the edge aligning device to the heat press device in the conveying direction.
