US 8,327,530 B2 · Installation for continuous application of particulate insulation to an elongate element

Abstract

An installation (1) for continuous application of thermally or electrically insulating material (6) around an elongate element (2) having a generally circular cross-section. The installation includes a forcing device (3), in form of a conical tube into which the element (2) is fed simultaneously at the large base end of the conical tube, a sheet (4), on which the insulating material (6) is placed, means for translation of the element through a circular section (2) of the sheet (4), and a device (7) for depositing of insulating material onto the sheet. Such an installation produces thermally insulated tubes or electrically insulated cables.

Dependent claims

An installation for the continuous application of thermal or electrical insulation in granular particle form to an elongate element having a circular cross-section, comprising:

a forcing device in the form of a conical tube for engaging in its large base, simultaneously, both such an element, and a sheet on which the granular particles of insulating material are deposited, which sheet is of sufficient width to envelop the outer circumference of the insulation material surrounding the elongate element,
means for driving in translation said element and said sheet, and
a depositing device for depositing the granular particulate insulating material on said sheet.

Dependencies are inferred from the claim text.
