Problems solved by technology

This conversion therefore becomes very time-consuming due to the assembly time and very expensive for the user, who has to always repurchase the structural drum with the suction tube and the assembly of the suction tube when processing new nonwovens

Embodiment Construction

[0019] exist figure 1 and 2 A drum 1 is shown in , which basically comprises a suction duct 2 and a structural drum 3 . The drum 1 is part of a process-technical plant (not shown), in which the product web made of unwoven or unwoven fibers is consolidated by means of high-energy jets and optionally Get a pattern.

[0020] The suction tube 2 can in turn be made of a solid cylinder equipped with clips 5 and spacer elements 6 . In order to carry away large quantities of liquid, the suction pipe 2 has a plurality of bores. The structural drum 3 can be configured as a thin sheet metal or fabric, which has a plurality of bore holes and optionally a surface structure. The clips 5 are designed as elongated strips which extend along the longitudinal axis of the suction pipe 2 . Furthermore, the catch 5 has notches 5 a which correspond to the projections 6 a of the spacer element 6 . The clip 5 is connected to the suction tube 2 by means of a fastening element 7 and clamps the spa...

Abstract

The invention relates to a device for hydrodynamically bonding nonwoven fabrics, woven fabrics or knitted fabrics, said device comprising a suction tube (2) which has a plurality of bores and on which a structuring drum (3) is arranged at a distance, characterized in that the distance between the suction tube (2) and the structuring drum (3) can be established by exchangeable distancing elements (6).

Description

technical field [0001] The invention relates to a device for hydrodynamically consolidating a nonwoven, woven or knitted fabric, in which a liquid, for example water, is sprayed from a plurality of nozzles onto the material to be consolidated. The material to be consolidated runs on a liquid-permeable rotating drum, which can additionally be subjected to a negative pressure in order to draw off the water. Usually, the drum comprises a cylindrical solid suction pipe with a plurality of bore holes which ensure a large drainage flow. Spaced apart from the suction pipe is a structured drum which may have fine openings for consolidating the fibres, but may also have a surface structure which imparts a patterned form to the material to be treated. Background technique [0002] According to the current state of the art, construction drums are always supplied together with the suction pipe and are replaced in the installation. Especially when the device is to be switched over to a...
