Publication number: 20110244066Abstract: An apparatus is configured to produce a spunbonded fabric. In order to achieve an airiness of the spunbonded fabric and ready adaptability to process parameters which are to be changed, a spinning beam together with a blowing apparatus is configured to be pivotable in a pivoting unit. A relatively high airiness is achieved by the filaments running obliquely onto the fabric belt below the spinning beam. Rotary leadthroughs or elastic feed lines to the spinning beam make the slight pivoting possible.Type: ApplicationFiled: May 11, 2011Publication date: October 6, 2011Applicant: OERLIKON TEXTILE GMBH & CO.

Publication number: 20110121480Abstract: A method for melt spinning, stretching, and winding a multifilament thread to form an FDY-yarn as well as a device for performing the method are presented. Hereby, a plurality of filaments are first extruded from thermoplastic melt, cooled to a temperature below the glass transition temperature of the thermoplastic material, and gathered to form a filament bundle without adding a preparation fluid. The filament bundle is then drawn-off at a speed above 1,500 m/min., heated to have a temperature above the glass transition temperature of the thermoplastic material, and stretched at a drawing speed above 4,000 m/min. Preparation of the filament bundle with a preparation fluid and winding the thread to form a spool is then performed.

Patent number: 7946398Abstract: A permanently excited magnetic hysteresis brake (1) comprises a support roller (7) rotatable about a fixed axle (9), a magnetic element (3), a hysteresis element (2) and an adjusting device for adjusting the position of the magnetic element (3) and hysteresis element (2) relative to one another and for adjusting the braking torque acting via the support roller (7) on the yarn (5). The magnetic hysteresis brake (1) has only one single mechanically acting actuator (18) for adjusting the braking torque. Both the adjustment of the braking torque to the desired value for the operation of the brake (1) and the adjustment of the braking torque when calibrating the brake (1) are carried out by actuation of this one actuator (18). The structure and handling of the magnetic hysteresis brake (1) can be simplified thereby. The magnetic hysteresis brake (1) can be used to maintain a uniform thread tension on textile machines.Type: GrantFiled: February 21, 2007Date of Patent: May 24, 2011Assignee: Oerlikon Textile GmbH & Co.

Patent number: 7917998Abstract: A method and a cutting device for the continuous cutting of fibers fed in fiber cables into fiber sections of particularly short length is disclosed. In order to avoid high friction forces between the formed knives and the fiber sections, and furthermore, to prevent excessive deforming of the fiber section during the transport between the knives, the knives are arranged at an offset to each other such that the fibers are initially cut into longer fiber sections, and into shorter fiber sections in a second step. The respective free space between the knives is increased due to the offset arrangement of the knives.Type: GrantFiled: April 1, 2009Date of Patent: April 5, 2011Assignee: Oerlikon Textile GmbH & Co.

Patent number: RE42765Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.Type: GrantFiled: October 12, 1998Date of Patent: October 4, 2011Assignee: Oerlikon Textile GmbH & Co.
