Abstract
A vibration device for an arrangement for producing a nonwoven fabric web, wherein the vibration device is configured to be arranged in a transverse direction of the arrangement under a conveyor belt for fibers from which the nonwoven fabric web is produced, wherein the vibration device is configured to cause the conveyor belt and the fibers transported thereon to vibrate, and wherein the vibration device includes a beam whose top side is configured to contact a bottom side of the conveyor belt at least temporarily, wherein the beam is supported or only excited or excitable by the vibration device so that the beam essentially performs or permits no vibrations in a conveying direction of the arrangement.
Claims15
A vibration device for an arrangement for producing a nonwoven fabric web,
- wherein the vibration device is arranged in a transverse direction under a conveyor belt of the arrangement for producing the nonwoven fabric web transporting fibers of the nonwoven fabric web, wherein the transverse direction is transverse to a conveying direction of the conveyor belt,
- wherein the vibration device performs vibrations orthogonal to the conveyor belt and causes the conveyor belt and the fibers transported thereon to vibrate,
- wherein the vibration device includes a beam whose top side contacts a bottom side of the conveyor belt at least temporarily,
- wherein the vibration device is excited or excitable so that the beam essentially performs no vibrations in the transverse and conveying directions of the conveyor belt,
- wherein the vibration device includes plural unbalance motors connected with the beam, and
- wherein two respective unbalance motors of the plural unbalance motors are arranged in sequence along a longitudinal extension of the beam extending transverse to the conveyor belt and the two unbalance motors are essentially arranged symmetrical to a longitudinal center of the beam.
