A fiber material is filled into a cavity of a tool to produce a product from the fiber material. The tool comprises a mold which defines the cavity therein and a holder which supports the mold. The holder is displaced to move the mold to at least one thermal treatment station The fiber material is thermally treated in the mold at the at least one thermal treatment station.

A liner, comprising a layered material in which a carded nonwoven wadding is thermally bonded to a thin carded nonwoven top layer, for upholstered furniture. In the liner, a high proportion of the staple fibers in the top layer are thin bi-component binder fibers. Further, at least 20 wt % of the staple fibers in the wadding is thick staple fibers. Furthermore, also the wadding comprises bi-component binder fibers.

A cover layer of a fleece material for an innerspring unit comprising a plurality of pocketed springs is manufactured by supplying at least two longitudinal fleece webs, which extend substantially parallel in a longitudinal direction and are spaced from one another, and repeatedly attaching a transverse fleece web, which extends between the longitudinal fleece webs in a direction substantially perpendicular to the longitudinal direction, to the longitudinal fleece webs. The transverse fleece web segments are attached to the longitudinal fleece webs such that they form together with the longitudinal fleece webs a frame-like structure serving as the cover layer.
