Abstract: The invention relates to a method for acquiring and managing morphological data of persons on a computer network, wherein said data is used for producing and/or delivering ready-made individually dimensioned clothes by at least one of the plurality of manufacturers. The inventive method consists, at a preliminary stage, in forming a first data base (3) on human body profiles by storing standard data sizes in a first computer system, in acquiring (6, 10), at a subsequent stage, representative current data of the morphology of said persons by means of a computerized acquisition system and in selecting (5, 8) personal data nearest to current data (6, 9) of each person from standard data. Said method is characterized in that personal data (12) is selected on a second computer system from a second database (4, 7), wherein standard data is organized by size ranges according to each manufacturer.

Abstract: An embroidery 202 is formed by sewing a polarizing fiber onto a suitable cloth 201. The polarizing fiber is composed of a polymer to which a polarization developing material is added and which is stretched after spinning. The embroidery 202 has seams arranged in a predetermined direction. The polarizing fiber exhibits different optical characteristics for a linearly polarized light having an electric field component in the stretched direction of the polymer (the extending direction of the fiber) and for a linearly polarized light having an electric field component perpendicular to that of the above linearly polarized light. Therefore, when a discrimination medium 200 is viewed through a polarization plate, the appearance of the embroidery 202 changes depending on the direction (rotation position) of the polarization plate, so that a discriminating function can be obtained.

Abstract: A method and apparatus for maintaining a yarn take-up point stationary. A first sensor, such as an optical sensor, is positioned proximate a first location of a yarn travel path to output a first signal representative of the position of a yarn at the first location. A second sensor, such as another optical sensor, is positioned proximate a second location of the yarn travel path to output a second signal representative of the yarn at the second location. A controller controls a temperature of a fluid employed to heat the yarn. The controller receives the first signal and the second signal, which are analyzed to produce a heat control signal that is used to control the temperature of the fluid. The heated fluid is used to texturize the yarn, such that the yarn is tensioned and maintained so that a yarn take-up point is substantially stationary.

Abstract: In an arrangement for the stretching and warping of thermoplastic warp threads, in particular polyester threads, there is provided an arrangement comprising a set of feeding rollers, a heating arrangement and a set of take-off rollers. The latter set of rollers has a higher circumferential speed than the former. Between the two sets of rollers there is provided at least one deflecting roller. The circumferential surface of this deflecting roller is divided into a heatable section and a relatively non-heatable section. The deflecting roller is rotatable from an operating position, in which the deflecting surface comprises the heatable surface portion, into a rest position wherein the deflecting surface presented is the non-heatable portion. In this way, the length of the thread exposed to heat can be extended between the feeding and take-off rollers without overheating of thread during the stopping of the arrangement. Other aspects of the mode of the process are also described herein.

Abstract: An apparatus is disclosed for simultaneously air jet entangling a plurality of advancing multifilament yarns. The apparatus comprises a plurality of elongate air jet beams, with each beam having a longitudinal air passageway extending along its length, and a plurality of parallel yarn ducts extending transversely through the beam. Also, an air jet aperture communicates between the air passageway and each yarn duct for directing an impinging airstream against an advancing yarn passing through the duct. The beams are mounted to a supporting frame, with the beams being horizontally disposed and vertically spaced apart, and the beams are each mounted for rotation about a horizontal axis which extends longitudinally along its length, and the supporting frame is itself mounted for rotational movement about a horizontal axis which is parallel to the rotational axes of the beams.

Abstract: The arrangement can transfer with respect to a beam, elastic threads having a predetermined initial extension. The arrangement has a first device for imparting a first thread speed to the threads being transferred. Also included is a controller and at least one tension roller, the latter rotatably mounted between the beam and the first device. The roller can impart a second thread speed to the threads and can stretch them. The threads at the beam are transferred at a third thread speed. Among the first, second and third thread speeds the two furthest upstream have an adjustable speed ratio. The controller can measure the tension of the threads traveling to the tension roller. This controller is operable to alter the speed ratio in response to the tension of the threads, to hold this tension at a predetermined magnitude.
