Title:
NEEDLE-PUNCHING OF FIBER WEB AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JPH10212654
Kind Code:
A
Abstract:

To provide a needle-punching method and apparatus capable of easily realizing an especially good needle-punching work without applying undesirable tensile load or elongation to a fiber web.

This needle-punching method and apparatus performs needle- punching of a fiber web 5 with needles 4 repeatedly thrust into the fiber web 5. The fiber web 5 continuously supplied to the needles 4 is further fed stepwise relative to the needles 4 when the web is released from the needles during the engagement of the needles and then taken out with a take-out roll 9. The web 5 is fed from the needle area by the weight of a dancer roll 11 before the take-out operation to get a tensile load on the fiber web 5 independent of the take-out motion with the take-out roll 9.
