Document Type and Number:
WIPO Patent Application WO/2017/208845
Kind Code:
A1
Abstract:
A folding device 70 according to the present invention is provided with: a conveyance unit for sending long double-sided cardboard 60 in a direction perpendicular to ripples in the long double-sided cardboard 60; a crease-imparting unit 100 for imparting creases to the long double-sided cardboard 60 at a prescribed interval L; a first conveyance platform 210 provided downstream from the crease-imparting unit 100, the first conveyance platform 210 having a prescribed upward angle of inclination; a second conveyance platform 220 provided downstream from the first conveyance platform 210, the second conveyance platform 220 having a smaller angle of inclination than does the first conveyance platform 210; a receiving platform 240 on which the folded long double-sided cardboard 60 is placed; and a receiving platform elevator unit 232 for lowering the receiving platform 240 while adjusting the same such that the uppermost surface of the long double-sided cardboard 60 placed on the receiving platform 240 moves downward from the second conveyance platform 220 by a distance that is 0.8-1.2 times the interval L. This makes it possible for continuously produced long double-sided cardboard to be folded into a bellows shape by a simple and compact mechanism.
