Thomas Wortmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20030167748
    Abstract: A texturing machine for crimping an advancing yarn and which includes a plurality of processing units and a plurality of feed systems. At least one of the feed systems is formed by a driven feed roll and a rotatable guide roll mounted in cantilever fashion on a machine frame, and about which the yarn is looped. A threading device is associated with the rolls for an initial threadup of the yarn before the start of the process, and by which it is possible to lay the advancing yarn against the circumference of the rolls with a total looping greater than 360°.

  • Patent number: 6536199
    Abstract: A method and apparatus for controlling a machine for false twist texturing a plurality of synthetic filament yarns and which includes a plurality of side by side processing stations. The plurality of processing stations are divided into a plurality of sections, with each section comprising a plurality of processing stations. The processing stations of each of the sections are monitored and controlled independently of the processing stations of adjacent sections, so that the processing of the yarns in each section is independent of the processing of the yarns in adjacent sections.

  • Patent number: 6209302
    Abstract: The invention relates to a false twist texturing machine and to a method of texturing synthetic yarns in, in each case, one processing point, in which a twist-stopping device, a heating device, a cooling device and a false twisting unit are disposed inside a false twisting zone. The yarn is withdrawn from the false twisting zone by means of a delivery mechanism. According to the invention, the twist-stopping device takes the form of a rotatable transport roller, around which the yarn is at least partially wrapped in a peripheral direction and which is drivable by a drive in such a way that the yarn is braked or delivered, so that the yarn tensile force is adjustable inside the false twisting zone.

  • Patent number: 6209301
    Abstract: A texturing machine is described which consists of a plurality of processing-points for thermoplastic threads. A feed bobbin, a first delivery mechanism, an elongated first heating device, an elongated cooling device, a false-twist unit, a second delivery mechanism and also a winding-up device are arranged at each processing-point. In this connection several feed bobbins are arranged above one another in a creel frame, and several winding-up devices are arranged above one another in a winding frame. The first delivery mechanism, the heater and the cooling device are located above the frames. In order to guarantee a careful course of the thread as well as operability, the first delivery mechanism is arranged together with a drive in an operational position directly upstream of the inlet of the first heating device.
