  • Patent number: 4988048
    Abstract: Method and apparatus includes determining the actual outer diameter of a bobbin or empty casing in the axial region thereof upon which a thread is being taken up. The drive velocity of the bobbin or empty casing is then changed relative to operating velocity as a function of the determined actual outer diameter of the bobbin or empty casing. Such adjustment corrects the circumferential velocity of the bobbin or empty casing in the take-up region of the thread for correspondence with the thread supply velocity. Otherwise, the circumferential velocity in such take-up region would deviate from the thread supply velocity on account of the conicity of the bobbin or empty casing.

  • Patent number: 4984422
    Abstract: A textile machine includes a plurality of tube support devices transported by a transport device to a tube transfer position for transfer of tubes between the tube support devices and a tube handling device. The tube support devices each include an upright member for individually supporting a tube in a substantially upright disposition, the upright member having a recess and an indicator device disposed within the recess. The indicator device cooperates with the transport device to indicate the presence of the upright member at an indicating position located at a predetermined location with respect to the tube transfer position. Accordingly, the transport device determines the presence of an upright member and responds accordingly to reliably position the upright member at the tube transfer position for transfer of the tube between the upright member and the tube handling device.

  • Patent number: 4982562
    Abstract: A U-shaped latch having a pair of resilient arms is fixed radially and axially in an annular groove formed in the neck of the spindle house. The latch is provided with a projection which passes through a hole in the neck into engagement above a collar integral with the spindle blade, thereby preventing axial movement of the spindle blade. The projection is formed so as to be centered on the inside rim of the latch so that upon radial shifting of the latch, the projection is moved from its engaging position to a disengaging position. The forked latch provides the necessary spring tension to hold the latch in place in either position.

  • Patent number: 4978081
    Abstract: A method and apparatus for disposing the yarn end of a package in a further handling disposition such as, for example, in the tube of the package, is provided. A preliminarily repositioning device receives packages from a ring spinning machine or the like, some of the packaging having their yarn ends in a preferred preliminary disposition and other of the packages having their yarn ends in a disposition displaced from the preferred preliminary disposition. The preliminarily repositioning device repositions the yarn ends of packages having displaced yarn ends from a displaced disposition to the preferred preliminary disposition. Thereafter, a relocating device relocates the yarn end of each package having its yarn end in the preferred preliminary disposition from that disposition to the further handling disposition. An advancing device advances packages between the preliminarily repositioning device and the relocating device.

  • Patent number: 4976099
    Abstract: A sliver feeding and opening device includes an outlet opening for passage of separated fibers to the rotor and an intake opening for the intaking of sliver to be separated into fibers. An intermediate opening is disposed in the chamber of the housing of the device at a location downstream of the outlet opening and upstream of the intake opening. An air stream reduction conduit extends from the intermediate opening to the outlet passage. The intermediate opening and the air stream reduction conduit conduct air from a revolving stream of air which revolves in the space between the opening roller and the cylindrical wall of the housing of the sliver feeding and opening device to prevent the revolving stream of air from detrimentally interfering with the orderly feeding of sliver at the intake opening to the opening roller.

  • Patent number: 4974488
    Abstract: The invention provides a rope splicing apparatus having an elongated tool portion including a main portion, a tip portion and a transitional portion. The main portion comprises a pair of straight and parallel main rod portions which are spaced apart at a main portion width along the length thereof. The tip portion comprises a generally U-shaped rod portion having a bend portion and leg portions which are spaced apart at a width narrower than the main portion width. The transitional portion has a pair of short rod portions flaring outwardly from the tip portion to interconnect the main rod portion to form a unitary tool. The tip portion is of a size which can penetrate strands of a single or dual braid rope to draw portions of the rope therethrough. The apparatus is used to practice a method of splicing such ropes to form eye splices, and marriage splices, with less difficulty than using conventional fids.
