Abstract: The invention relates to the production of profiled hose nipples. The invention was based on the object of providing a method and an apparatus which allow hose nipples of the type outlined in the introduction to be produced in a simple manner such that the formation of burrs is avoided and there is no reduction in diameter. This object is achieved in that during the forming of pipe portions (1) in the apparatus (2, 7, 9) according to the invention in the region of the subsequent ring-shaped webs (4) of the nipple profile (3), the material of the pipe portion (1), at its outwardly pointing end (4), does not come into contact with the tool in the region of the parting joints (6) of the apparatus (2, 7). This can be realized by additional cavities (14) in the tool (2, 7).

Abstract: A device for the determination of parameters, particularly for therapeutic compression measures on limbs (10), comprises an anatomically-modelled limb (10), to which the compression measures may be applied, with sensors (42), provided on the limb (10), for recording said parameter. The surface (44) of the limb (10) is at least partially elastically-deformable in at least one direction and at least one simulation device for a muscle (22, 24) is provided in the limb (10), which may be controlled to give a merely partial deformation of the surface (44) of the limb (10).

Abstract: A bandage with lengthwise elasticity in the warp direction, comprising a textile expanse woven in leno weave and having weft threads, leno threads and elastically extensible warp threads. The warp threads are cotton-elastic threads.

Abstract: The invention relates to a flexible tubular lining material which comprises a seamless plush textile tube and a plastic film layer arranged coaxially and freely around it as well as a method for the production of conduit and/or pipe linings which comprises impregnation of the flexible tubular lining material with a curable resin composition, the introduction of the impregnated material into an inversion tube, the subsequent pressing of this arrangement into the conduit or pipe section to be lined and the curing of the resin under maintenance of applied pressure in the inversion tube.

Abstract: A cohesive bandage fabricated according to a method comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacryate ester and alkyphenyl polyethylene glycol ether to at least one fabric face is disclosed. In one embodiment, the coating is applied by an airless method microselectively in statistical distribution where the quantity of coating is controlled by pump pressure. Alternatively, an aqueous dispersion of polybutyl acrylate ester and carboxymethyl cellulose is microselectively and cohesively coated on both sides of the fabric by screen printing to produce a regular dot pattern on both faces of the fabric.

Abstract: The textile fabric is used as a wound dressing in much the same way as dressing gauze with improved characteristics compared with the latter and comprises a central web portion of man-made fibers having a high surface tension, and on either side thereof web portions formed from absorbent, cellulosic yarns. The central web portion is connected by looping to the outer web portions so that after folding, a nonstick wound dressing is obtained in which the hydrophobic man-made fibers functioning as the wound covering, come to rest on the wound, while the folded layers of cellulosic fibers behind it, act as an absorbent layer.

Abstract: The invention relates to a cohesive, self-adhesive, rigid or elastic bandage for fixing, compression and support dressings and permanent elastic compression and support dressings for medical purposes and a process for the manufacture thereof. The bandage comprises a web of warp and weft threads or warp threads in the form of a woven fabric having a porous structure and an amount of ultra fine particles of an adhesive, such as a rubber adhesive, distributed over and bonded to both the exposed surfaces of the warp and weft threads to provide adhesive particles bonded to the threads on both sides of the fabric. The adhesive particles are uniformly distributed over both bandage surfaces without the fiber groups adhering to one another or to the projecting fiber ends of the two surfaces, the particles being of a size distribution and amount sufficient to provide adhesion between overlying bandage surfaces without substantially reducing the porosity and elasticity of the fabric.

Abstract: An elastic, non-sticking wound textile formed of a highly elastic knitted fabric with a mesh-forming thread of a completely synthetic material facing the wound and highly absorbent yarns incorporated as the weft.

Abstract: The invention relates to a wound dressing which prevents or at least reduces sticking of the dressing to the surface of the wound due to contact with moisture from the wound and which without the use of over twisted threads has a controllable lifting action and an excellent secretion-absorbing action, whereby cutting of the dressing into strips does not lead to lateral fraying due to the cutting of the mesh as is the case with known knitted fabrics and in which the further use leads to complication. The present wound dressing comprises a knitted fabric formed with a basic stitch construction and with a plurality of inlay threads having a Z or S twist, the yarns of the inlay threads having the same thickness and twist, and being inserted as slightly or greatly displaced wefts.

Abstract: The invention relates to a fabric which is highly longitudinally elastic in the warp direction and easily tearable in the weft direction, or highly longitudinally elastic in the weft direction and easily tearable in the warp direction, or highly longitudinally elastic and easily tearable in both the warp and weft directions, which is adhesively or self-adhesively coatable and has a crepe structure, whereby in bandage form it can be used as a fixing and compression bandage after distortions, luxations, fractures and similar injuries, as well as preventatively against injuries liable to occur when playing sports.
