Title:
NEEDLE PUNCH APPARATUS FOR FIBER WEB
Document Type and Number:
Japanese Patent JPH0860517
Kind Code:
A
Abstract:

PURPOSE: To provide a needle punch apparatus for a fiber web enabling the improvement of mass balancing and the smoothening of the rocking of a needle beam through the wide balance between inertia force and a first order moment of inertia by a simple means.

CONSTITUTION: In an needle punch apparatus, inertia force and a first order moment of inertia are widely balanced by the following construction: a crank mechanism 6 guides and drives a needle beam 1 in cooperation with a rocker link 12, and the needle beam 1 holds a needle board 2; a pair of connecting rods 9 of the crank mechanism 6 are driven in mutually opposite senses; one end of each connecting rod 9 is pivoted on the crank shaft or eccentric shaft 7, 8; at the same time, the other ends are mutually connected via a linking piece 10 which is pivoted on a rocker link 12; and in a mid-position of the stroke of the crank mechanism 6, the plane of symmetry 17 between both the crankshafts or eccentric shafts 7, 8 is almost at right angles to the plane 16, which is defined by the center of gravity S of the total mass consisting of the crank mechanism 6, the rocker link 12, the needle beam 1, the needle board 2 and the needle 3, and the rocker shaft 13 of the rocker link 12.
