Problems solved by technology
This solution is not often applied due to its cumbersome implementation
The laying direction of the reinforcing fibers has to be constantly switched from layer to layer, which severely reduces productivity and does not prevent over-twisting (fiber winding around itself)

Embodiment Construction
[0059] figure 1 A schematic side view of one possible use of the hose building machine is shown. According to this schematic diagram, the hose under construction rotates about its own axis while the laying head advances in the direction of the same axis. However, the invention is not limited to this type of use, and since only the relative movement of specific elements (rather than movement with respect to the ground) is of interest to the solution concerned, so long as the hoses under construction are simultaneously rotating and advancing motion, or the rotation of the roller around the hose, or any combination of these, the invention can be applied.
[0060] exist figure 1 In the shown arrangement, the hose 3 under construction undergoes a rotation relative to the laying head 12, wherein the laying head 12 and the roller support platform 15 for securing the roller 14 move in a direction parallel to the longitudinal axis of the hose. Refer to the image 3 and Figure 4 L...

Abstract
The object of the present invention is a method for constructing a hose reinforced with helically laid fibers, wherein the hose (3) under construction undergoes a rotational and advancing movement relative to the laying head (12) and wherein the reinforcing fibers pass from the roller Barrel (14) unfolds. The roller (14) rotates around two axes, the first axis (A) is the main axis of the roller and the second axis (B) is approximately parallel to the direction of fiber unwinding, wherein the roller (14) revolves around the second axis (B) in the same direction of rotation as the hose (3) in construction. The device for carrying out the method comprises a laying head (12) and a roller support platform (15), wherein the hose (3) in construction undergoes a rotational and advancing movement relative to the laying head (12), and wherein the reinforcing fibers (10) is unwound from the drum (14) by the endless fiber guide (1). A further object of the present invention is a method for constructing a hose reinforced with helically laid fibres, wherein the fiber guide (2) is laid on the surface of the hose by means of a rotating self-adjusting annular fiber guide (2) arranged substantially coaxially with the hose Reinforcing fibers (10). The invention also relates to a device for implementing the above method.
Description
technical field [0001] The object of the present invention is a method and a device for processing fiber-reinforced hoses, in particular high-pressure hoses comprising spirally laid reinforcement layers. Background technique [0002] High-pressure fiber-reinforced hoses, especially larger diameter high-pressure fiber-reinforced hoses, are often referred to in the literature as flexible tubing to distinguish them from commonly used industrial hoses and tire inner tubes. [0003] Flexible tubing enables a liquid or gas to flow between two connection points that can move relative to each other. As a result, coiled pipes are used in the offshore oil industry where they must meet a complex set of requirements, the most important of which is pressure maintenance. This means that flexible pipes must withstand high working pressures even above 1000 bar. Furthermore, the tube must resist the chemical action of its entrained medium and must cope with the stresses caused by the diffu...
