Title:
NEEDLE PUNCH DEVICE FOR FIBER WEB
Document Type and Number:
Japanese Patent JPH07197369
Kind Code:
A
Abstract:

PURPOSE: To provide a needle punch device which enables the stroke change of a needle board with simple means.

CONSTITUTION: A needle beam 1 held by the needle board 2 of the needle punch device for the fiber web is supported by an oscillatable oscillation link 10 and is so constituted that the needle board 2 is made movable upward and downward along an arcuate orbit 12 around the oscillation axis 11 of the oscillation link 10 driven by a crank mechanism 6 via this oscillation link. Further, the arms 9 of the oscillation link 10 are provided with plural pivotal bearings 15 at the points of distances different with respect to the oscillation axis 11. A connecting rod 8 is selectively pivoted to one of these pivotal bearings 15 to make the pivot 14 of the connecting rod 8 displaceable along the arms 9 of the oscillation link 10, by which the stroke between the upper inversion position and lower inversion position in the lifting motion of the needle board 2 is regulated.
