Method and apparatus for manufacturing fibre-reinforced hoses

The object of the invention is a method for building hoses reinforced with spirally laid fibres, where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibres are unwound from drums (14). The drums (14) are rotat...

Beschreibung
Zusammenfassung:	The object of the invention is a method for building hoses reinforced with spirally laid fibres, where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibres are unwound from drums (14). The drums (14) are rotated about two axes, the first axis being the principal axis of the drums (A) and the second axis (B) being nearly parallel with the direction in which the fibres are unwound, where the direction of rotation of the drums (14) about the second axis (B) is the same as the direction in which the hose under construction (3) is rotated. The apparatus for carrying out the method comprises a laying head (12) and a drum support platform (15), where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibres (10) are unwound from drums (14) through a circular fibre guide (1) The further object of the invention is a method for building hoses reinforced with spirally laid fibres, wherein the reinforcing fibres (10) are laid on the hose surface through a rotating self-adjusting circular fibre guide (2) arranged substantially coaxially with the hose. The invention also relates to an apparatus for carrying out the above method.
