A pipe for forming air flow pipelines in a structure that includes a flexible tube made from composite material, the tube having, on the length of same, sections for which the wall of the tube is stiffened by means of structural elements made from a rigid composite material incorporated into the wall of the tube. The structural elements are configured and arranged at the surface of the tube in such a way as to form a lattice framework surrounding the wall of the tube. The pipe further includes electrical conductors, disposed longitudinally on the wall of the pipe, the electrical conductors having a straight path at the stiffened sections of the pipe and a meandering path at certain of the non-stiffened sections of the pipe, the meandering allowing the conductor to tolerate the possible twisting of the pipe when it is installed in the structure.

Fabrication of formed hoses is provided which include an innermost elastomer layer, a first fiber-reinforcement region, and multiple second fiber-reinforcement regions. The first fiber-reinforcement region has a first fiber-reinforcement density, and is disposed, at least in part, at a bend region of the formed hose, and the multiple second fiber-reinforcement regions have a second fiber-reinforcement density, and are disposed at least at the first and second end regions of the formed hose. The second fiber-reinforcement density is greater than the first fiber-reinforcement density, and results in the first and second ends of the formed hose being less radially-deformable than the bend region of the hose. This facilitates providing a mechanical fluid-tight connection with a hose barb fitting when the formed hose is slid over the hose barb fitting, absent any clamp over the formed hose and hose barb fitting connection.

The invention relates to a fluid line (1) having a tube (2) made of a synthetic material. The fluid line (1) should be guided in a flexible manner. To this end, it is provided that the synthetic material can be subjected to a temperature of at least 150° C., and that along part of the length thereof, the tube (2) is surrounded by an expansion protection (8).

A duct system with multiple flex duct sections includes a duct take off, a duct register boot, at least one flexible duct assembly that includes an inlet coupler, an outlet coupler, and a duct section. The inlet coupler and outlet coupler are terminally connected to the duct section completing the flexible duct assembly as the number of duct assemblies determines the length of the duct system. The duct takeoff is mounted to the inlet coupler, and the duct register boot is mounted to the outlet coupler as the duct takeoff is in fluid communication with the duct register boot through the flexible duct assembly. Additionally, an air controlling device can be mounted with respect to three different places, wherein the three different places are in between two couplers, the coupler and the duct takeoff, and the duct register boot and the coupler to improve the efficiency of the duct system.

The disclosure provides a hose manufacturing machine, which includes a spool and a pintle assembly. The spool rotates about a central axis. The pintle assembly includes a spindle and a brake arrangement. A first end of the spindle is attached to the spool along the central axis. The brake arrangement includes a brake disc and a force plate. The brake disc includes a brake surface and is attached to a second end of the spindle. The force plate includes a number of brake pads. The brake pads has a relatively higher wear coefficient than the brake disc. The brake pads of the force plate contact the brake surface of the brake disc to at least partially restrict the rotational motion of the spool.
