  • Patent number: 7568262
    Abstract: A device and a method for serially depositing a filamentary strand into several cans of a can creel with a traversable depositing device. The depositing device comprises a conveyance means which is held in such a manner that it can be moved and which can be guided into several depositing positions. The strand is fed continuously to the conveyance means and from each depositing position at least one of the cans of the can creel can be filled by the conveyance means. In order to make the filling of a plurality of cans in the can creel as rapid and flexible as possible, the depositing device comprises a robot with a multi-axis robot arm, where the robot carries the conveyance means at the free end of its robot arm. Thus, the conveyance means can be guided, in its positioning as well as in its movements for filling the can, by the multi-axis robot arm of the robot.

  • Publication number: 20070234763
    Abstract: The invention relates to a device for the steam treatment of a moving fiber strand, comprising an elongated steam chamber. To seal the steam chamber, a pair of feed rollers is connected to and seals a feed chamber on a feed side in such a way that the nip constitutes the feed into the steam chamber. The opposing exit side is equipped with a pair of exit rollers, which forms a second nip and which is connected to and seals the other end of the steam chamber by means of an exit chamber, in such a way that the second nip constitutes the exit from the steam chamber. The feed roller pair and the exit roller pair are respectively formed by a fixed sealing roller and a displaceable sealing roller. The aim of the invention is to achieve a seal between the sealing roller and the associated sealing chamber, irrespective of the operating position of the displaceable roller.

  • Publication number: 20070199297
    Abstract: A method and an apparatus for producing staple fibers, wherein in a first step a tow is formed from melt spun filaments and deposited into a can, and wherein in a second process step the tows of a plurality of cans in a can creel are withdrawn, treated, and cut to staple fibers. To obtain as much as possible short times of interruption between the first and second process steps, the invention provides for depositing the tow in the first process step directly into the can accommodated in the can creel, with the cans of the can creel being filled one after the other.

  • Publication number: 20070199281
    Abstract: An apparatus and a method for laying a tow into a can, wherein a tow feed device advances the tow into the can, with the tow feed device being movable to oscillate in a plurality of directions of movement. To obtain the highest possible flexibility when laying the tow into the can, the invention provides for moving the tow feed device by a multiaxial robot, which mounts the tow feed device at the free end of a robot arm.

  • Patent number: 7191580
    Abstract: An apparatus for depositing a filament tow in a stationary can. To this end, the filament tow is conveyed to the can by a conveyance means which includes a pair of driven reels. For deposition into the can, the filament tow is guided in such a way that the feed position of the filament tow in the can constantly changes. To allow the filament tow to be deposited with a high filling density, for deposition into the can the filament tow is guided by two separate oscillating motions of the conveyance means during conveying which are transverse to the conveyance direction. In this manner, undesired reactions on the filament tow are advantageously avoided during deposition.

  • Publication number: 20050062188
    Abstract: An apparatus and a method for spinning and depositing a tow (15). To this end, one or more fiber bundles (7) are melt spun by means of a spinning device (1), and withdrawn as a tow by a withdrawal system (2). Subsequently, the tow (15) is laid by means of a depositing device (3) into a can (4). To be able to apply the necessary withdrawal forces to the tow (15), the tow (15) advances along an S-shaped guide path by partially looping the rolls (9, 10) of the withdrawal system (2). To be able to change the degree of the looping on the rolls, in particular for piecing and threading the tow (15), some of the rolls (10) of the withdrawal system (2) are mounted for displacement on the machine frame in such a manner that they permit changing the guide path of the tow (15).
