Embodiment Construction

[0032] figure 1 Apparatus for forming mats of uniform or shaped fiber bundles is shown. The device includes a dosing device, which is designed here as a fiber tow feeder 2 . Downstream of this dosing device, the resulting fiber tow mat is conveyed to the infeed area of ​​a web former 3, in particular a card. The resulting fiber tow mat 12 may also be conveyed directly to a pneumatic fleece former (not shown) or curing machine 50 (see figure 2 ).

[0033] The fiber bundle feeder 2 distributes the fiber bundles to the discharge conveyor belt 4, and the discharge conveyor belt 4 travels endlessly in circles and maintains tension through several deflection wheels 6, only one of which is shown in the accompanying drawings.

[0034] In order to increase the density of the tow material emerging from the tow feeder 2 , an upper drum 8 can also be arranged in the exit region of the tow feeder 2 . This upper roller 8 is driven in the opposite direction to the direction of the wheel...

Abstract

The feed device for supplying individualized fibers or fiber flocks to a transport device, which serves to transport the formed fleece or fiber flock mat onward, includes a plurality of feed segments arranged horizontally next to each other and a plurality of individually actuatable feed rollers, wherein a separate feed roller is assigned to each feed segment. In addition, at least one driven opening cylinder, which cooperates with each feed roller, is also provided.

Description

technical field [0001] The invention relates to a feeding device for supplying individual separated fibers or fiber bundles to a feeding device. Background technique [0002] In the production of fiber fleece, the fiber tows are first distributed from the tow feeder to a conveying device which, in the first option, conveys the fiber tows in the form of a mat of tows to a web forming device (preferably a carding machine). In the second option, the tows are fed directly to a pneumatic fleece former; or, in the third option, the tows are fed directly to a curing machine (such as a needleloom). [0003] In said first option, the carded web (which can also be called single- or double-ply fleece) formed in the web former is then conveyed to a fleece layup machine which lays down the fibers by cross-lapping net to form a multi-layer fleece fabric. The multi-ply fleece can then be cured by a suitable curing machine, such as a needle loom. Overall, the aim is usually to produce a...
