Abstract:
1. A device for producing a fiber product by depositing melt-spun fibers on a delivery belt comprising: a spinning device associated with an upper surface of the delivery belt; and, a vacuum device associated with a lower surface of the delivery belt to produce a vacuum flow, wherein the vacuum device includes a vacuum chamber that acts together with the spinning device to deposit the fibers on the delivery belt, the vacuum chamber including a stationary lower vacuum box connected to a vacuum attachment channel and a mobile upper vacuum box, which are coupled to one another in a pressure-tight manner to encompass a passageway therebetween, wherein the vacuum chamber defines a cross-section such that a substantial portion of the cross-section guides the vacuum flow wherein the upper vacuum box can be adjusted in relation to the lower vacuum box.
