Problems solved by technology

When welding or deformation is used as a means of joining one layer of material to another, the welding or deformation is applied throughout the thickness of the pipe wall, to the detriment of insulation
Also, this method is not very reliable

Embodiment Construction

[0044] Therefore, if figure 1 As shown, a device 1 for producing a tubular product comprises a tube forming device 2 , a tube holding device 3 , a pulling device 5 and an energy application device in the form of a laser emitter 4 . Referring to the tube forming device 2 shown in more detail figure 2 , which includes a series of holes 6 for forming the body material 7 into a tubular shape. Refer to the tube holding device 3 shown in more detail image 3 , which includes a circular hole 8 for holding the subject material 7 drawn therethrough in a tubular shape. As explained further below, the pulling device 5 is used to pull the subject material 7 through the tube forming device 2 and the tube holding device 3 . In addition, as explained further below, the laser 4 is used to direct the laser beam 19 onto a laser absorbing composition disposed on the host material, so that the host material 7 is shaped into a tube, and the tube holder 3 is used to absorb the laser light. Kee...

Abstract

Apparatus for manufacturing a tubular product comprising a tube forming means, a tube maintaining means, a drawing means and energy application means, in which the tube forming means comprises a formation aperture or series of apertures adapted to form a subject material drawn therethrough into a tubular shape, in which the tube maintaining means comprises a circular aperture or series of apertures adapted to maintain the subject material drawn therethrough in the tubular shape, in which the drawing means is adapted to draw the subject material through the tube forming means and the tube maintaining means, in which the energy application means is adapted to direct an energy to the subject material, or an energy absorbent component disposed thereon, such that the subject material is set in the tubular shape, and in which the tube maintaining means is adapted to maintain the subject material in the tubular shape during absorption of the energy.

Description

technical field [0001] The present invention relates to a device for the production of tubular products, in particular but not limited thereto, for the production of electrically insulating pipes. Background technique [0002] Electrically insulating tubing is commonly used for electrically insulating joints of electrical wires, such as those found in the coils of electric motors. Such tubing is constructed of thin layers of electrically insulating material such as polyester. These products come in many forms and are manufactured using many different methods. [0003] One type of tube is fabricated from several narrow strips of electrically insulating polymer, all coated with adhesive and wound around a cylindrical mandrel at an oblique angle to form a continuous length with a helical seam the tube. The tube can be cut to length at a later time. [0004] Another type of tube is made by rolling a short length of electrically insulating polymer onto a cylindrical mandrel a...
