process for the manufacture of tubular elements from synthetic fibres, the ineinanderschiebbar, a fishing rod with controlled movement to form, and this method produced elements

摘要

Rovings of tough fibres (10) previously impregnated with thermosetting resin are wound around a rigid mandrel (9) with end diameters (D1) and (D2), driven in rotation, with pitches (p1) situated on the end regions (L) of the mandrel and p2 in the middle of the mandrel, such that the pitches (p1) and (p2) lie within a range of values 75 mm /= p1 DIVIDED 2 /= 100 mm 100 mm /= p2 DIVIDED 2 /= 250 mm, the diameter (D2) being greater than or equal to 8 mm, the ratio of the diameters D2 DIVIDED D1 lying in a range such that 0.67 /= D2 DIVIDED D1, the pitch p1 lying on the end regions (L) of the mandrel such that (L) lies between 50 mm and 100 mm.
