Title:
DEVICE FOR INTERMITTENTLY FEEDING SHEET
Document Type and Number:
Japanese Patent JPH09156806
Kind Code:
A
Abstract:

To prevent the generation of unevenness of the intermittent feeding variable of sheets in the case of high-speed carrying and in the case of low-speed carrying by supporting one surface or both surfaces of a sheet with abutment of a pair of supporting means in the fore and aft direction at the predetermined position of the sheet, and intermittently pressing the sheet surface between the pair of supporting means in the fore and aft direction.

A delivery roll 8 of a feeding device 7 is always rotated at the constant speed so as to feet a fiber sheet 6 in the arrow A direction, and a rotary plate 13 is rotated in the arrow B direction at the predetermined speed. With the rotation of the rotary plate 13, a pressing roll 14 presses the top surface of the fiber sheet 6, and the fiber sheet 6 is pushed down between a pair of supporting rolls 11, 12 in the fore and aft direction so as to be forcibly sagged downward, and during the time when the sagging width W is reduced from the maximum to 0, the fiber sheet 6 of a needling device 1 side is stopped. When the pressing roll 14 is separated from the top surface of the fiber sheet 6, the fiber sheet 6 of the needling device 1 side is fed in the arrow A direction by the delivery roll 8.
