Abstract
Apparatus for folding a sheet-form material in a zigzag fashion. Lower and upper guide members are provided in opposed relation in a frame. Sheet-form material is placed under tension between the upper and lower guide members. Plural lower up-and-down movable members are arranged at regular intervals on the lower guide member. Plural upper up-and-down movable members are arranged on the upper guide member at regular intervals and at positions alternate with the lower up-and-down movable members. Fold imparting members are arranged respectively at upper ends of lower up-and-down movable members and at lower ends of upper up-and-down movable members. Upper and lower up-and-down movable members are driven to move toward each other, sequentially from one end side of the upper and lower guide members and toward the other end side, to give folds to the sheet-form material.
