Apparatus for producing fiber molded article useful in upholstered furniture, preferably vehicle seats, comprises pneumatic fiber feeding unit, heating device with heat exchanger, and molded parts of a mold, which are mutually displaceable

摘要

Apparatus comprises a pneumatic fiber feeding unit (2), an associated heating device (4) with a heat exchanger (6) for heating hot air, and a mold (12), which on at least one side includes through-flow holes (14) for air transportation. The mold includes an exhaust valve on the side of the through-flow hole, and includes multiple closeable exhaust ports arranged one behind the other in the feeding direction of the fibers according to . The mold is divided and molded parts are mounted in a mutually displaceable manner. Apparatus for producing a fiber molded article, comprises a pneumatic fiber feeding unit (2), an associated heating device (4) with at least one heat exchanger (6) for heating hot air and a mold (12), which on at least one side includes through-flow holes (14) for air transportation. The mold includes an exhaust valve arranged on the side of the through-flow hole, and includes multiple closeable exhaust ports arranged one behind the other in the feeding direction of the fibers according to . The mold is divided and the molded parts are mounted in a mutually displaceable manner and the molded parts are displaceable into each other. An independent claim is also included for producing a fiber molded article from a thermally-crosslinkable fiber material, comprising transporting the fibers via an air flow into a mold provided with through-flow holes, splitting the mold and moving the mold parts apart from each other prior to filling, compressing after filling the fibrous material by closing the mold, and heating the fibrous material by hot air until the fibers are connected to each other, where the fibers in the mold before compression are oriented perpendicularly to the feeding direction and in the direction of the air flowing out from the mold according to , where the mold is associated with air guiding devices arranged one behind the other in the feed direction of the fibers, which comprise shutter devices, and the shutter devices for filling the mold are opened by the supply openings for the fibers exiting in the direction of the supply opening and an adjustment for the orientation of the fibers takes place by a layer in the form of located fibers.
