IPC: B65H51/18
Filed: 1987-07-24
Abstract: PURPOSE: To carry out the uniform zigzag folding with uniform peaks and valleys by forming folds with folding rods at a prescribed interval in a blanket of beltlike fibers in the width direction, then nipping the intermediate parts between folds with upper and lower transverse rods and contracting the respective nipped parts with a contracting mechanism of a pantograph. CONSTITUTION: A blanket 1 of beltlike fibers on a belt conveyor 2 is pressed with fold rods 3 to form folds at a prescribed interval in the width direction and the blanket 1 is then lifted to a height adjacent to plural upper transverse rods 9. Lower transverse rods 8 are simultaneously pushed out from the lower side to nip the blanket 1 in the intermediate positions between the folds. The respective nipped parts of the blanket 1 nipped from the upper and lower sides are then uniformly contracted with a contracting mechanism and compressed into a zigzag folded state with the nipped parts as peaks and the fold parts as valleys.  The compressed blanket 1 is compressed and held with pressure contact plates of a holding machine from the left and right and the upper and lower transverse rods 8 and 9 are then removed to thereby afford a zigzag folded blanket 1 having a uniform height of the peaks and valleys in good yield without resultantly requiring the trimming.
