Definitions

  • ABSTRACT A needle-felting machine comprising two needle boards each having a multiplicity of barbed needles projecting from a surface thereof and disposed so that the needles in each board face away from the other board.
  • the boards are arranged in linear opposition to each other and are reciprocably driven from a common drive shaft and gearing disposed intermediate the boards.
  • a web of loosely matted fibers is fed past .the needle surface of each board by a plurality of feed rolls driven from the common drive shaft and is simultaneously penetrated by the needles of both boards so as to obtain a balanced force system.
  • This invention relates to needle-felting machines for felting of textile fibers by the action of barbed felting needles and more particularly to a novel and improved needle-felting machine in which the mass and acceleration forces are substantially perfectly balanced so that high-speed operation may be obtainable.
  • the rudimentary elements of a needle loom for producing a needle felted fabric comprises a needle board having a multiplicity of barbed needles and means to reciprocate the board toward and away from a web of fibers which preferably moves continuously in a horizontal path beneath the barbed needles.
  • Apparatus of this type is disclosed in U.S. Pat. No. 3,340,586 issued to J. Zocher, one of the coinventors of the present invention.
  • the present invention overcomes these problems of the prior art by providing a needle-felting machine having a pair of spaced apart needle boards arranged in linear opposition to each other and driven from a common drive shaft which synchronously reciprocates the boards linearly in opposite directions toward and away from the advancing web.
  • the treedles in each board face away from the other board so that as the needle boards reciprocate the needles of both boards simultaneously penetrate the web and simultaneously withdraw from the web.
  • the common drive is disposed between the two needle boards and absorbs the counter directed mass forces of the oppositely moving needle boards. In this manner substantially all the opposed mass forces are absorbed by the drive shaft and not the frame of the machine.
  • a yet still further object of this invention is to provide needle-felting machine having a pair of spaced apart needle boards each including a multiplicity of barbed needles projecting from one surface thereof, said needle boards being disposed such that the needles in each board face away from the other board, means for advancing said web pass the needle surface of each board, and drive means for synchronously reciprocating the boards linearly in opposite directions toward and away from said web so that all the needles simultaneously penetrate said web and simultaneously withdraw from said web.
