Problems solved by technology

[0006] One disadvantage of this other method is that the glass wool has a natural tendency to swell and come out of the container (even if suction is applied) and therefore the glass wool often stretches over the weld area for the second end cap and fouls the weld area

Embodiment Construction

[0053] In the following detailed description, reference is made to the accompanying drawings, which illustrate examples of devices according to the present disclosure. It is intended that this example be considered merely illustrative and that the scope of the invention is not limited to this example.

[0054] figure 1 The apparatus 1 is used to produce the fiber product 100 of constant cross-section, and this cross-section is in image 3 is shown in .

[0055] In this disclosure, "upstream" and "downstream" are defined with respect to the normal flow direction of yarns and segments through the apparatus.

[0056] Equipment 1 includes from upstream to downstream:

[0057] Texturized Nozzle 8,

[0058] a rotating nozzle 13 having a first internal channel 12 with a first outlet 14,

[0059] Binder injector 55,

[0060] Room 1 20,

[0061] hardening unit 52, and

[0062] Circular saw 60.

[0063] The texturing nozzle 8 is fed with a multifilament yarn 6 made of glass fil...

Abstract

Method for producing a fibrous product comprising: passing a texturized yarn (10) through a first passage (12) having a first outlet (14); projecting the texturized yarn (10) from the first outlet (14), inside a chamber (20), so as to fill the chamber (20) with the texturized yarn (10), thereby forming a first segment (31) of the fibrous product; moving the first segment (31) away from the first outlet (14); and forming a second segment (32) of the fibrous product in place of the first segment (31) and contiguously to the first segment (31), as many segments as necessary being contiguously formed by repeating the above steps. Apparatus for implementing the method.

Description

technical field [0001] The present invention relates generally to fibrous products and apparatus and methods for producing fibrous products. In particular, the fibrous product may be an acoustic and / or thermal insulation product such as duct insulation. Background technique [0002] Fiber products are used for many industrial purposes, such as for the manufacture of insulation products, structural products, reinforcement products, decorative products, and the like. Insulation products include thermal insulation products that resist the flow of heat and sound insulation products that may have sound barrier properties to impede the transmission of sound or sound absorption properties to dissipate or absorb sound, or have sound barriers properties and sound absorbing properties. Examples of fibrous thermal and / or acoustic insulation products are duct insulation used to prevent the transfer of heat and / or sound from the interior of ducts to the surrounding air. For example, s...
