The band element has a T-shaped or Y-shaped cross section, is formed of a different material from the roller blind web, and has a smaller material thickness than the roller blind web. In addition, the invention relates to correspondingly configured subassemblies and roof arrangements.

Abstract: A roller blind arrangement, in particular for a vehicle, with a roller blind web. The roller blind web can be wound up at least at one end by a winding device to form a roller blind winding having a geometrical center axis. The roller blind web can be unwound in an unwinding direction. The winding device has a guide element arranged with respect to the geometrical center axis of the roller blind winding in a direction essentially opposite to the unwinding direction and is designed to limit a movement of the roller blind winding in the direction opposite to the unwinding direction. The invention also relates to a roof arrangement with a roof opening, a roof opening frame that bounds the roof opening, and a roller blind arrangement. The roller blind arrangement is arranged in the roof opening and is mechanically coupled to the roof opening frame.

Abstract: In the case of an arrangement for transporting at least one thread treated in a thread conditioning plant from a delivery roller pair to a transport belt which takes up the thread in the form of thread loops, an adapter is arranged downstream of the delivery roller pair, with which adapter it is possible to equip the arrangement as required with a stuffer box or an oscillating loop laying device. By simply exchanging an aggregate it becomes possible, depending on the type of operation required, to crimp and heat set threads or to treat uncrimped threads.

Abstract: A flat-jet nozzle 1 for high-pressure cleaning apparatus has a nozzle mouth passaage formed by the intersection of a depression 21 with half-round base 22 shaped into a nozzle body 2 and a channel 6 leading to the nozzle mouth. In the zone of intersection with the depression 21, the channel has a spherically vaulted wall 12. The width b of the resulting passage .alpha. and the angle between the wall 12 bounding the edge 26 and the longitudinal axis 17 of the channel are dimensioned in such manner that a point defined by this value pair lies inside of a zone bounded by a hyperbolas. This tolerance range is given by the equation:(b-B).multidot.(.alpha.-.alpha..sub.o)=C,in which: the width b is measured in millimeters (mm) and the angle .alpha. is measured in degrees (.degree.), the constant B lies in the range between 0.785 mm and 0.875 mm, the constant .alpha..sub.O lies between 8.25.degree. and 17.25.degree., and the constant C lies in a range from 12.degree. mm to 13.degree. mm.

Abstract: A texturizing device for a yarn conditioning plant comprises a stuffer box, which is made from one piece. The cross section of the stuffer box channel is circular and predominantly constant; however, a taper and/or a yarn retarding lid can be arranged at the exit end of the stuffer box channel. In order to attain a crimping effect when the production is started, the stuffer box comprises at least one air inlet opening, which leads into the stuffer box channel, and which is directed against the channel inlet opening.

Abstract: A method and apparatus is disclosed for heat-setting carpet yarn by conveying continuously running yarn through a heat-setting chamber. To facilitate production of variable texture yarn, a controllable oscillating yarn supply tube assembly is provided for laying down various yarn patterns on a conveyor belt which travels through the heat-setting chamber. The oscillating yarn supply tube assembly is configured to facilitate switch of production between straight-set and various highly crimped textured yarn patterns via simple adjustment of the drive motor which oscillates the yarn supply tube. The apparatus can be used for a new machine as well as for conversion kits for existing carpet heat-setting machines having stuffer boxes supplying highly crimped yarn to a conveyor belt.

Abstract: An energy efficient apparatus and method for the continuous heat treatment of a carpet yarn or the like is disclosed, and which includes a conveyor extending through a heat treatment chamber, and with the conveyor comprising a number of endless belts which are adapted to support the yarn in downwardly hanging relaxed helically arranged loops. The lower portions of the loops are supportingly lifted during movement through each of the entrance and exit openings of the chamber, which permits the dimensions of the openings in the chamber to be minimized and thereby reduce heat loss therethrough.

Abstract: A method and apparatus for the continuous heat treatment of a carpet yarn or the like is disclosed, and wherein the yarn is advanced in loop form through a heat treatment chamber and then along a downstream accumulation zone. A control system is provided for insuring that all portions of the yarn remain in the heat treatment chamber for a predetermined residence time, and such that all portions of the yarn will possess uniform properties and appearance in a finished carpet. The control system continuously monitors the number of loops of yarn in the apparatus, and in the event that the number of loops either exceeds a predetermined maximum or is less than a predetermined minimum, a yarn severing mechanism located upstream of the heating chamber is actuated. By appropriate selection of the maximum and minimum numbers, all of the yarn downstream of the severing mechanism will be able to pass through the heating chamber in the predetermined residence time, and thus no off-standard yarn will be produced.

Abstract: A yarn conditioning plant for processing of yarn at high temperature is improved by provision of arrangements for enabling a plurality of yarn threads that have simultaneously been processed upon a single yarn transport to be wound individually upon separate spools. In accordance with a first preferred embodiment, a tension balancing means is provided which includes a potentiometer that is acted upon by the thread tension of yarn threads passing thereover so as to control the operating speed of individually driven spools. According to a further embodiment, the tension of the individual yarn threads is compensated by the use of two separate storage devices upon which the individual processed yarns can be separately wound in a manner so as to achieve a uniform tensioning thereof.
