PRENEEDLE-PUNCHING APPARATUS FOR FIBROUS WEB
Document Type and Number:
Japanese Patent JPH10102371
Kind Code:
A
Abstract:

To constitute the subject apparatus by a simple means so as to significantly improving esp. preneedle-punching conditions within the range of leading a fibrous web into a relevant guide unit.

This needle-punching apparatus is equipped with a needle board 2 having needles 4a, 4b reciprocatingly drivable in the piercing direction and each bearing varves to bring a fiber together and a fibrous web guide unit 6 made up of abed plate 7 standing against the needle board 2 and a stripper plate 8 situated between the bed plate 7 and the needle board 2. To ensure conditions advantageous for preneedle-punching, the needle 4a in the needle board 2 located in the coming side area 12 of the guide unit 6 bears the varves with a distribution denser than the case with the other needle 4b, or with a distribution, though coarser, lying within the contour of the operative portion for the needle 4a.
