Method and apparatus for producing a liner hose (30) for lining channels and pipes, comprising a circumferentially closed inner film hose (32) and at least on fibrous strip (34) wound onto the inner film hose (32) and impregnated with a curable reaction resin, wherein the inner film hose (32) is drawn in a winding apparatus (40) onto a support tube (8) which is mounted on one side and arranged substantially horizontally, at the free end (10) of which a winding mandrel (12) is arranged having a transport apparatus (16) which, during the circumferential winding of the fiber strips (34), transports the inner film hose (32) in a feed direction (36) to a stationary supporting surface (18) which is arranged at the free end (10) of the winding mandrel (12) and over which the liner hose (30) is conveyed further, wherein the inner film hose (32) is drawn over the free end (13) of the winding mandrel (12) onto the support tube (8) against the feed direction (36).

The invention relates to a method for manufacturing a tubular body (2) for a packaging in tube form (1), comprising the following steps: ) definition of the geometrical characteristics of the tubular body (2) to be produced; ) creation of an initial image (6) covering the surface of the tubular body (2) to be produced, said initial image (6) having a right lateral edge and a left lateral edge; ) creation of an intermediate image (8) from the initial image (6) by adding a lateral strip (13) to one of said edges of the initial image (6), said lateral strip (13) comprising a copy of the other of said edges of the initial image (6); ) printing of at least one intermediate image (8) on a sheet, the intermediate image (8) being disposed such that the lateral edges of the image are parallel to the direction of unwinding of the sheet; ) cutting of a small strip on each lateral side of the intermediate image (8) to form a final image (10); ) shaping of the sheet as tubular body (2) and edge-to-edge assembly to obtain a continuity of the design between the right edge and the left edge of the image.

Devices and methods for making devices that temporarily occlude spaces within the body to provide a therapeutic effect.

The invention relates to a multilayer tube, comprising a tubular inner film made of modified polytetrafluoroethylene, and one or more layers of a planar textile fibrous material, which is saturated with a curable resin, and optionally an outer film. The outer film is preferably made of UV impermeable material. The multilayer tube can be used for repairing pipes, but it can also be used as a stand-alone pipe for transporting fluids such as liquids and gases.

A method of forming a structural tube may include urging a substantially flat thermoplastic sandwich sheet against a mandrel and heating the thermoplastic sandwich sheet to a temperature below a glass transition temperature. The method may further include allowing the thermoplastic sandwich sheet to cool and removing the mandrel, thereby forming a tube portion.

An airbag for a blood pressure measuring device for fixing a cuff, including: a main sheet member which spreads in two layers forming a bag body, wherein a constricted portion is formed on the bag body, the constricted portion narrowing the air chamber with respect to the width direction, a pair of sub sheet members are disposed so as to correspond to the respective layers of the main sheet member, the sub sheet member occupying a region including at least a portion corresponding to the constricted portion, and the pair are respectively welded to the layers of the main sheet member at the constricted portion, the pair being welded to the corresponding layers of the main sheet member at a center near portion away from the constricted portion toward a center side with respect to the width direction.
