Title:
APPARATUS FOR PRODUCING NEEDLE FELT
Document Type and Number:
Japanese Patent JPH06240555
Kind Code:
A
Abstract:

PURPOSE: To prevent a generation of crease on matrix cloth used for the integral entangling with bat fibers in a piled state without any manual work.

CONSTITUTION: A crease removing apparatus 17 is installed at a forward course of a needling machine for producing felt by entangling bat fibers on matrix cloth 2 in multiple layers. The apparatus 17 consists of a pair of endless belts 18a and 18b covering from the central part of the matrix cloth 2 to the both edges and a driving motor 20 to circulate the endless belts 18a and 18b in the directions in which the parts of the belts facing to the reverse side of the matrix cloth 2 move towards each edge. Multiple needles 23 are planted on the outer peripheral surfaces tilting backwards to circulating directions. When entangled with the bat fibers the cloth matrix 2 is sent to the needling machine while the reverse surface of the matrix cloth 2 is scratched out from the center parts towards each edge by the needles 23 through the driven belts.
