Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
118 words
An apparatus for making a filler material comprising a. a yarn feeding and cutting device, b. a tubular guide, c. yarn transfer means arranged for taking up the cut yarn filaments and forwarding them along said tubular guide, d. a plurality of movable containers each of which has a curved inner surface and is adapted to be moved in a manner to be disposed in a position facing the outlet of said tubular guide, means for moving said containers in succession to and from said position, e. gas jet means for forming the cut yarn filaments into a shperical shape of each of said containers, and f. means for taking the spherically shaped products out of said containers.
Claim 2
Independent Claim
118 words
