Abstract: The invention relates to an applicator (1) for replacement hair strands, one end of the hair of which is embedded into a thermoplastic element. The applicator has a punch/die unit (5, 6), the mutually facing working profiled sections of which are adapted to the shape of at least one thermoplastic element. In order to ensure a fault-free, continuous hot-melt adhesion between a person's own hair strands and the replacement hair strands, the punch (6) is arranged on a pivoting head (10) which supports an additional punch (11) with substantially the same contours, wherein the punch (6) is provided with a heating device (12), and the additional punch (11) is provided with a cooling device (13).

Abstract: Replacement hair strands having a hair-joining element comprise a flat, thin platelet with one replacement hair strand embedded on an end of the platelet, and at least one thin rib that protrudes at an angle with respect to the strand direction of the replacement hair strand from one of two flat sides of the platelet. The rib has flat sides that taper toward its free end. The rib has a height and a base thickness, and the height is greater than the base thickness. The base thickness is approximately the same as a thickness of the platelet. The rib is configured to envelop natural hair strands longitudinally aligned with the strand direction of the replacement hair strand to securely connect the replacement hair strand to the natural hair strands.

Abstract: A hair extension remover, which comprises two crimping jaws, wherein one crimping jaw can be moved relative to the other with a drive. A liquid container that can be pressurized and that is in the form of a piston-cylinder unit, opens into the vicinity of the crimping jaws. In order to ensure exclusive linear motions, the drive of the crimping jaws and the pressurization of the piston-cylinder unit are each designed as a gear drive. Each gear drive can comprise either a gear rack having a pinion or a gear wheel segment, or a gear spindle having a movement nut. The two gear drives can be coupled in an adjustable and motion-transmitting manner.

Abstract: The invention relates to a replacement hair strand having a hair-joining element, consisting of a flat thermoplastic platelet having a replacement hair strand embedded in the end thereof, wherein in order to ensure a secure join with a head hair strand at least one rib running obliquely with respect to the strand direction protrudes from one of the two flat sides of the platelet. At the base thereof, the rib can have approximately the thickness of the platelet, and towards the free end thereof, the rib can be tapered. The height of the rib corresponds preferably to at most the longitudinal extent of the platelet extended in the strand direction.

The two gear drives (3, 4, 5; 11, 12, 13) can be coupled in an adjustable and motion-transmitting manner.

Abstract: A hair weft (5) for hair extension and thickening, in which contiguous hairs (2, 6) are connected to a transversely-running weave strip (3) by an adhesive support (4). In order to ensure various methods of attachment, the weave strip (3) projects beyond the adhesive support (4). In addition, the weave strip (3) together with the adhesive support (4) can be attached at a distance from the hair ends.

Abstract: A thermoplastic hair connecting element is composed of an essentially prismatic body, wherein ends of replacement or extension hair can be embedded in the hair connecting element so as to extend in a longitudinal direction of the element. The hair connecting element has at least one free surface with a profiling extending inclined relative to the longitudinal direction of the element.

Abstract: A U-shaped thermoplastic hair-connecting element is provided with at least one intermediate partition disposed between parallel legs of the U-shaped element. The intermediate partition can be designed as a longitudinal partition which runs essentially parallel to the legs and which projects from a connector of the U-shaped element. Alternatively, the intermediate partition can be a transverse partition which runs essentially transverse to the legs and perpendicular to the connector which connects the legs to one another. There can also be provided longitudinal partitions together with transverse partitions. Foreign hairs can be embedded into the hair-connecting element either during manufacturing, or in a separate manufacturing step.

Abstract: An applicator for replacement hair strands, having hair embedded with one end in a U-shaped thermoplastic element, has a matrix having a recess for receiving the U-shaped thermoplastic element of the replacement hair strand. The applicator also has a stamp movable into the recess of the matrix. An actuating and heating device is provided into which the stamp and the matrix are inserted. The recess of the matrix is penetrated by a channel extending transversely to the movement direction of the stamp. The channel receives a magazine provided with receiving and storing spaces for replacement hair strands. The actuating and heating device has a step-by-step advancing device for the magazine.

Abstract: Method for producing a hair strip wherein hairs lying adjacent to one another are joined together striplike by fusing on and cooling of a strip of synthetic material. For secure cementing of the hairs these are joined together at a predetermined distance from one of their two ends by pouring on of a strip of synthetic material, following which the protruding ends are cut off after solidification of the synthetic material. For improving the hold of the hairs, they may be joined in the region of the strip of synthetic material either before or after this has been poured on by additionally stitching with a thread preferably consisting of the same material.

Abstract: Hair clip that has two connected arms (1, 2) which move between an open and a closed position. To separate out individual strands of hair, a replaceable comb (4) is attached along the length of at least one of the two sides of one of the two arms (1); said comb's teeth (5) extend laterally past the second arm (2) in the closed position.

Abstract: For a single pole plug connector arranged at the end of a single conductor shielded cable, an insulator is used which is slipped on an appropriately prepared cable end. A sealing sleeve is disposed between the insulator and the shield wires folded over backwards on the cable jacket. The shield wires are then brought through a finger-like extension of an elastic cap by means of a connnecting lead, the cap resting also on the insulator and the cable jacket. The shield side end of the connecting lead is fixed relative to the cable by a hose clamp.
