Problems solved by technology

However, the dispersing section is also used to simultaneously disperse the fibers over the entire width of the fleece to be produced, which means that it is not possible to produce a fleece with a locally defined more precise uniformity also in the width direction of the fleece
[0011] A disadvantage of all of these devices and methods described above is the impossibility of achieving precise local coverage by fibers; that is, the impossibility of precisely dispersing the fibrous material over a locally defined area
The area density of the resulting final product cannot be locally increased, locally decreased or uniformed to a satisfactory extent

Embodiment Construction

[0036] figure 1 A first embodiment of the feeding device according to the invention is shown. In this example, the feeding device 2 comprises a feeding arm 4 . However, other designs of the feed device 2 are also conceivable.

[0037] in accordance with figure 1In the example of , the feed arm 4 is arranged above the two-dimensional deposition surface 6; here, the two-dimensional deposition surface 6 is the upper harness of the endless drive belt. In the present example, the feed arm 4 is a pivot arm having legs 8, 10 connected to each other at a first, preferably horizontal, pivot axis 12 in the region where the legs 8, 10 intersect. Form an inverted V shape. Thus, the second leg 10 is pivotably connected to the first leg 8 via the first pivot shaft 12, so that the angle between the two legs 8, 10 (ie the angle of the inverted V shape) can be adjusted by the second leg. The pivoting of the part 10 becomes larger or smaller.

[0038] In addition, the end of the first leg...

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 fibers or fiber flocks. Background technique [0002] A preferred field of application for these types of feed devices is the production of three-dimensional moldings of fibrous materials. Three-dimensional moldings of fiber materials are used, for example, in the automotive industry, where these components are used for sound dampening. These moldings are used, for example, as door linings, rear shelves and roof linings. The floor and connecting walls extending from the cabin to the trunk and from the cabin to the engine compartment are also lined with molded sound dampening pieces. The goal is to use a one-piece piece with the largest possible area. The sheet metal parts of the body have highly formed irregular shapes to ensure rigidity and save material. These sheet metal parts include, for example, mounts for additional vehicle components as well as through-openings for cable channels and steering co...
