A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.

Apparatus and methods are provided for creating tubular devices, e.g., as components for catheters, sheaths, and or other devices sized for introduction into a patient. In one embodiment, a method is provided for making a tubular device using a sheet of material including a coated first surface. The sheet is rolled around a mandrel until longitudinal edges of the sheet are disposed near or adjacent one another, e.g., without attaching the longitudinal edges together. A tubular braid is positioned over the sheet-wrapped mandrel, one or more tubular segments are positioned over the tubular braid, and heat shrink tubing is positioned over the tubular segments. The resulting assembly is heated to cause the tubular segments to at least partially reflow and/or otherwise laminate the tubular segments to the tubular braid and sheet. The heat shrink tubing and mandrel are then removed to create the tubular device.

Subject matter of the present invention is a method of applying coating layers (9) to a substrate (1, 11, 21, 31), wherein the substrate (1, 11, 21, 31) is drawn through a coating chamber (2) containing a pressurized coating agent (3) being liquefied or softened by means of a thermal exposure, wherein the substrate (1, 11, 21, 31) is drawn through a drawing tool (8), wherein the coating agent (3) serves as a lubricant between the drawing tool (8) and a surface of the substrate (8) and wherein at the same time the coating layer (9) is applied to the surface of the substrate (8). Subject matter of the invention is also a corresponding apparatus for applying a coating layer (9) to a substrate (1, 11, 21, 31). By means of the invention coating layers can be applied to a substrate in an efficient and economical way.

A method is shown for installing a heat tube on a section of pre-insulated piping. A metal carrier pipe is covered with a first layer of foam insulation. Next, a routing device is used to cut a longitudinal slot along the length of the pipe so that the pipe exterior surface is exposed from the insulation. A heat tube is then installed within the longitudinal slot, whereby the heat tube contacts the exterior surface of the metal carrier pipe. A second layer of foam insulation is then sprayed onto the exterior of the metal carrier pipe, covering the previously formed longitudinal slot and installed heat tube. A polyolefin coating is then applied over the insulation to form a protective outer jacket for the insulated pipe.

The continuity of a functional layer of a web (32, 60, 78) is assessed by forwarding the web, detecting (42, 63) the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component (360) in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component (360) in the functional layer. The detectable component (360) can be active or passive. Also included are systems for carrying out the process.

The invention relates to a method for coating a textile hose (4) with a thermoplastic sealing material (5), in particular polyurethane-based, in a coating device (2). The textile hose (4) has a longitudinal direction and a circumferential direction and is manufactured continuously in the longitudinal direction and in the circumferential direction, in particular formed from a tubular knit hose; the textile hose (4) is fed to the coating device (2) and is continuously drawn onto a mandrel (6) extending in the longitudinal direction and approximately in the vertical direction (8) and is continuously transported further over this mandrel (6), the mandrel (6) being supported and oriented according to the position by at least one support means (10) provided outside the textile hose (4). The thermoplastic sealing material (5) is provided in a heated flowable state and is fed continuously to an entire outer circumference (38) of the textile hose (4) which is continuously transported over the mandrel (6) in such a way that some of the thermoplastic sealing material (5) can penetrate into the textile hose (4) and/or can adhere to the outer circumference (38) of the textile hose (4) and forms a closed superficial coating, and the textile hose (4) coated in this way is then continuously drawn off from the mandrel (6).
