ABSTRACT:
A work-sheet folding apparatus including a table having a hole; a support plate which is provided above the table and on which the work sheet is placed; a first folding member which cooperates with the support plate to fold an outer peripheral portion of the work sheet in a first direction perpendicular to the support plate; a first moving device which moves the first folding member in the first direction; second folding members which cooperate with the support plate to fold back the outer peripheral portion of the work sheet in a second direction parallel to the support plate; second moving devices which move the second folding members in the second direction; a support member which surrounds an outer peripheral portion of the support plate and which supports the second folding members; a pressing device which presses the support plate and the support member on the table; a movable member which is provided in the hole of the table such that the movable member is movable upward and downward; and a supporting device which supports the movable member such that an upper surface of the movable member is flush with an upper surface of the table, and which permits the movable member to be moved downward by being pressed by the folded-back outer peripheral portion of the work sheet when the support plate is pressed on the table by the pressing device.
