Abstract
The feed device for feeding individualized fibers or fiber flocks to a transport device which includes a first feed segment and a second feed segment for feeding in a starting material. Each feed segment has its own feed roller and each feed roller is individually actuatable. The feed device also includes an opening roller, which cooperates with the feed rollers of the first and second feed segments to individualize the starting material into fibers or fiber flocks. The first and second feed segments are arranged a certain distance apart in a circumferential direction of the opening roller.
Claims11
A feed device for feeding individualized fibers or fiber flocks to a transport device, the feed device comprising:
- a plurality of feed segments at least comprising a first feed segment and a second feed segment, wherein the first feed segment has a first feed roller to feed a first fiber sliver of fiber fleece strip and the second feed segment has a second feed roller to feed a second fiber sliver or fiber fleece strip, and wherein the first and second feed rollers are individually actuatable;
- and
- an opening roller, which cooperates with the first feed roller to individualize the first fiber sliver or fiber fleece strip at the first feed segment into fibers or fiber flocks and which cooperates with the second feed roller to individualize the second fiber sliver or fiber fleece strip at the second feed segment into fibers or fiber flocks;
- wherein the first and second feed segments are arranged a certain distance apart in a circumferential direction of the opening roller.
A nonwoven-forming machine for forming a material web, the nonwoven-forming machine comprising:
- a transport device conveyed in a transport direction;
- and
- a first feed device for scattering individualized fibers or fiber flocks onto the transport device, the first feed device comprising:
- a plurality of feed segments at least comprising a first feed segment and a second feed segment, wherein the first feed segment has a first feed roller to feed a first fiber sliver or fiber fleece strip and the second feed segment has a second feed roller to feed a second fiber sliver or fiber fleece strip, and wherein the first and second feed rollers are individually actuatable;
- and
- an opening roller, which cooperates with the first feed roller to individualize the first fiber sliver or fiber fleece strip at the first feed segment into fibers or fiber flocks and which cooperates with the second feed roller to individualize the second fiber sliver or fiber fleece strip at the second feed segment into fibers or fiber flocks;
- wherein the first and second feed segments are arranged a certain distance apart in a circumferential direction of the opening roller.
