Abstract
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.
Claims3
In apparatus for manufacturing an endless needled paper machine felt up to a predetermined maximum width, the felt comprising at least one ply formed by a plurality of overlapping loops of a sliver web, which apparatus comprises
- a needling machine having a working width equal to said predetermined maximum width and
- a sliver web feeder operable to feed a sliver web to said needling machine, wherein the improvement comprises
- a needling device of smaller working width than the needling machine between said needling machine and said sliver web feeder, the needling device and the feeder having the same working width, and
- means for reciprocating the needling device with the feeder in unison throughout the working width.
Dependencies are inferred from the claim text.
