Title:
DEVICE FOR NEEDLE PUNCH ON ONE SURFACE OF FELT
Document Type and Number:
Japanese Patent JPH01321968
Kind Code:
A
Abstract:

PURPOSE: To improve the punching frequency of needles without depending on the load for penetration and drawing of needles through a felt by forming guide chips of specified height between longitudinal lines of through holes of a doffing plate disposed between a needle plate and a felt mounting plate.

CONSTITUTION: A doffing plate 3 having through holes 4 for needles 5 is disposed between a needle plate 1 which is vertically movable and a felt mounting plate 2. The needles 5 arranged in longitudinal lines in the needle plate 1 along the passing direction 6 of a felt are penetrated the through holes 4 of the doffing plate 3 by the vertical movement of the needle plate 1 to penetrate the felt passing on the felt mounting plate 2 so as to form fiber loops to increase bonds among fibers of the felt tissue. In this process, a guide plate 7 having the height 0.2 to 2 times as the diameter of the through holes 4 is disposed between the longitudinal lines of the through holes 4 so as to prevent the felt surface from intruding into the through holes 4 when the needles 5 penetrating the felt are extracted.
