  • Patent number: 5544829
    Abstract: A pallet transport system for a textile cheese winding machine includes a cop delivery and storage track for supplying cops to be rewound, an empty tube return track, and a plurality of transport tracks each extending through one winding head of the bobbin winder transversely between the supply and return tracks. The entrance region of each transverse transport track is closable by selectively operable blocking mechanism disposed in operation to permit empty pallets to enter the transverse transport track while pallets equipped with cops are shunted. In this manner, the transverse transport tracks serve as a storage device for empty pallets which provides the advantage that, at the completion of a batch, the time needed by the bobbin winder to properly end the batch is shortened, and hence the machine's efficiency is increased.

  • Patent number: 5542269
    Abstract: A three-bar warp knitted fabric whose technical back has both a satin-like surface and a walewise ribbed effect is produced on a three-bar warp knitting machine by knitting ground yarns on the machine's middle bar to provide structural and dimensional integrity to the fabric, knitting satin-effect yarns on the machine's top bar in extended underlaps to produce a satin-like technical back of the fabric, and inlaying elastic yarns from the machine's bottom bar in a two-in, one-out alternating pattern to create the appearance of walewise ribs in the satin-like technical back surface.

  • Patent number: 5537810
    Abstract: In order to improve the smoothness of operation of a shaftless spinning rotor embodied as the rotor of an axial field motor wherein the rotor is supported by a magnetic gas bearing, a guide magnet arrangement for generating a magnetic guiding field is decoupled mechanically from the drive component of the stator. To that end, separate magnet and stator components are connected to one another by means having both elastic and damping properties, e.g., rubber. This mechanical decoupling makes it possible for the separate components to execute vibration independently of one another and for vibration to be transmitted from one component to another only in highly attenuated form. Hence, machine vibration can substantially be prevented from affecting the smoothness of rotor operation. Tangential forces generated by harmonics and radial forces caused by magnetic or mechanical asymmetries can likewise be absorbed by the stator, with an attendant improvement in smoothness of rotor operation.

  • Patent number: 5535582
    Abstract: A drive for a shaftless spinning rotor wherein the spinning rotor is embodied as the rotor of an axial field motor utilizes axially opposed yoke-forming, magnetically conductive elements disposed respectively on the opposite sides of an air gap formed between the spinning rotor and the stator in combination with at least one magnet (preferably either permanent magnets or electromagnets) on one or both the rotor and stator arranged concentrically to one another and to the rotor axis. The present magnet/yoke arrangement does not require exact mutual alignment of oppositely located magnets nor their homogeneous polarization. The present arrangement is self-adjusting because of the generation of a point-symmetrical field which in operation forms a sort of magnetic potential depression. Magnetic drive and guide fields are advantageously decoupled in order to reduce their mutual interference.

  • Patent number: 5535955
    Abstract: An apparatus for automatically forming yarn reserve windings selectively on either end of an empty tube prior to winding a yarn package thereon utilizes a threaded spindle and spindle nut assembly for supporting one of a pair of tube clamping plates for selective longitudinal displacement of a tube clamped therebetween during rotation of the tube to place the yarn reserve windings thereon. The hand of the threaded connection between the spindle and spindle nut determines the longitudinal direction in which the tube is displaced and, in turn, determines the end of the tube about which reserve windings are to be formed. In one embodiment, the spindle and spindle nut assembly are exchangeable for a like assembly formed with opposite threads, thereby to alter the longitudinal direction of tube displacement.

  • Patent number: 5535956
    Abstract: The handling of textile bobbins and textile bobbin tubes, particularly in yarn end preparation of textile bobbins, is improved by the pallet of the present invention which has an arbor of longer axial length than the textile bobbin tube it supports so as to protrude sufficiently from the textile bobbin tube that the arbor can be gripped while the textile bobbin remains supported on the pallet. A releasable connection between the base plate and arbor of the pallet in the preferred form of a functionally detachable plug-type snap connection allows for a temporary separation of these components. A pot-like covering body for the textile bobbin is connected to the base plate, particularly for conical or cylindrical cross-wound bobbins.

  • Patent number: 5530176
    Abstract: A method and apparatus for disposing of hazardous waste material by burning in a cement-producing kiln includes providing a predetermined quantity of hazardous waste material in a predetermined configuration, and providing an apparatus for aerating and using that apparatus to aerate the hazardous waste material to produce a supplementary fuel having a predetermined density. The method also includes providing an apparatus for injecting the hazardous waste material into the cement kiln and includes the step of injecting the hazardous waste material into the cement kiln at a predetermined injection rate thereby causing the hazardous waste material to burn while suspended in the kiln atmosphere and causing the hazardous waste material to supplement the primary fuel source and maintaining the cement-producing temperature within the kiln.

  • Patent number: 5522241
    Abstract: A ventilated textile elastic band is formed of a crochet-type warp knitted construction from a set of warp yarns respectively formed in warpwise-extending chain stitches in spaced groups of successive adjacent wales separated from each other group by plural wales unoccupied by any warp yarn, a set of elastic yarns extending within the chain stitches of the warp yarns, and a set of filling yarns traversing coursewise within the warp yarn chain stitches in a predetermined filling traversal pattern producing an absence of any filling yarn in selected courses of the unoccupied wales thereby forming parallel lengthwise columns of spaced ventilation openings. The grouped arrangement of the warp yarns and the widthwise traversing of the filling yarns provides widthwise structural integrity to the fabric band while the elastic yarns provide lengthwise stretchability and the ventilation openings permit air and moisture to pass freely through the band.

  • Patent number: 5517880
    Abstract: A bottom die for a stamping tool for producing cardboard blanks consists of a composite plate made from a support foil and a top layer consisting of phenol-resin bonded paper with a textile insert. Scoring grooves are milled into the top layer of phenol-resin bonded paper to serve as a counter contour of the top die of the stamping tool. The bottom die can be removably disposed on the bottom tool plate of a stamping machine by means of an adhesive layer which is self-adhesive on both sides. According to the invention, the scoring grooves are formed through the top resin bonded paper layer of the bottom die to the level of the flexible support foil, whereby the bottom die is given a relatively large degree of flexibility. Thus, a repeated use of the bottom die sheet is possible. In addition, a method for producing a bottom die for a stamping tool, employing the above-described die, is disclosed.

  • Patent number: 5515672
    Abstract: Because of the pot spinning process, it is more difficult to automate the supply of empty tubes, respooling of the spinning cake on an empty tube, and the removal of the spinning cops in a pot spinning machine than with other spinning processors. The present invention provides a completely automatic exchange of spinning cops for empty tubes at the spinning stations of a pot spinning machine by utilizing the yarn guides of pot spinning stations to place full yarn cops produced thereat into an upright position on carriers located on a movable conveyor extending underneath the spinning pots. With the spinning cops deposited onto the conveyor and with the yarn guide returned to a spinning position, the conveyor can transport the carriers with the spinning cops away and can deliver empty tubes to the spinning stations for receipt by the yarn guides to continue the spinning process.
