摘要： An apparatus for continuously cutting fibers to a predetermined length to provide staple fibers comprising at least one rotatably supported disc having a peripheral surface formed with a circumferential row of engagement projections radially outwardly protruding therefrom and spaced at intervals of a predetermined pitch and at least one cutting blade, the disc being rotatable sequentially past a delivery station and then past a cutting station during one complete rotation thereof. The fibers are at the delivery station delivered successively onto the disc so as to cause the fibers to be substantially traversed in a zig-zag fashion while extending alternately outwardly and inwardly around the engagement projections, and then partially pressed against such every other engagement projections by means of an endless belt drivingly trained around the disc. Portions of the fibers, which extend outwardly around every other engagement projections, are, when brought to a cutting station, successively cut by an impact shearing action created by the cutting blade in cooperation with the every other engagement projections around which those portions of the fibers extend outwardly, thereby providing the staple fibers.

摘要： An apparatus for continuously manufacturing a corrugated sheet having a varying fold width and also having fold lines extending either straight or in wavy or zig-zag fashion in a direction widthwise thereof. The apparatus includes upper and lower toothed rolls each made up of a group of toothed discs and having a circumferential groove defined between each neighboring toothed discs. At least one of the upper and lower toothed rolls is supported for adjustment in position relative to and in a direction towards and away from the other of the upper and lower toothed rolls. Upper and lower guide bars while extending in a direction parallel to the upper and lower toothed rolls are accommodated within the circumferential grooves for movement in a direction towards and away from each other over a distance corresponding to the height of each tooth of any one of the upper and lower toothed rolls. During a continuous passage of the web of sheet through a biting region defined between the upper and lower toothed rolls, the web of sheet is alternately folded by the interaction between the upper and lower toothed rolls to provide the corrugated sheet.
