APPARATUS FOR PRODUCING NEEDLE PUNCHED ENDLESS PAPERMAKING FELT

摘要

Apparatus for manufacturing endless needled paper machine felts comprising at least one ply formed by a plurality of overlapping loops of a sliver web comprises a needling machine having a working width corresponding to the width of the paper machine felt, and a sliver web feeder which is adapted to be reciprocated throughtout the working width of the needling machine. To ensure that the needling can be properly effected without a formation of wrinkles, a needling device having a working width corresponding to that of the feeder is provided between the feeder and the needling machine and is adapted to be reciprocated in unison with the feeder throughout the working width of the needling machine.
