Embodiment Construction

[0041] figure 1 A device 1 for manufacturing fiber products based on glass wool, for example for manufacturing insulating panels for air distribution ducts, is schematically shown. The apparatus 1 comprises a fiberizing unit 11 to which molten glass is supplied in the usual manner from a furnace and through forehearths (these are not shown). The device 1 comprises a binder applicator 12 provided for applying, in particular by spraying, a binder onto the web of fibers 13 produced by the fiberizing unit 11 . The fibers are collected on a perforated conveyor 14 in the form of a mat 15 of glass wool fibers mixed with a binder. The binder may be a heat curing resin, such as a phenol / formaldehyde resin, or any other type of suitable binder.

[0042] At the end of the conveyor 14 , the device 1 comprises a crosslinking furnace 2 . The furnace has a closed interior 3 in which a lower conveyor 4 and an upper conveyor 5 for transporting and calibrating mats 15 circulate. In the usua...

Abstract

This forming device is intended to be mounted on a pallet (6) of a conveyor for transporting the fibrous product through the heating device, wherein the pallet (6) defines a receiving surface (63) for the fibrous product. The forming device has: a forming body (8) whose main body portion (81) is intended to be arranged in front of the receiving surface (63); and at least one anchoring element (9) intended to be arranged behind the receiving surface (63) And fixed on the pallet. The forming body (8) and the anchoring element (9) comprise complementary buckle parts (88, 99), and when the body portion (81) of the forming body (8) faces the receiving surface (63) and the anchoring element (9) is in the receiving When the rear of the surface (63) is fixed to the pallet (6), it is possible to push the main part of the forming body (8) towards the receiving surface (63) by applying a single Engages complementary snap features (88, 89) towards thrust (F1).

Description

technical field [0001] The invention relates to a forming device for shaping a fibrous product intended to be fitted on the pallet of a conveyor for transporting the fibrous product through a heating device. The invention also relates to a device for manufacturing fiber products comprising such a forming device. Background technique [0002] Insulating fiber products, such as insulating panels for air distribution ducts, typically comprise mats of mineral fibers, such as glass fibers, held together by an organic binder. The manufacture of such fiber panels involves first fiberizing and laying the fibers on a perforated moving conveyor or conveyor. A mass of fibers is pressed onto the conveyor by means of suction boxes arranged below the conveyor. During fiberization, a binder having heat-activatable tack properties is sprayed onto the drawn fibers in the form of a solution or a suspension in a volatile liquid such as water. This adhesive typically comprises a heat curable...
