Abstract: A circuit for controlling the speed of a DC motor provides delay and sampling means in the feedback loop to delay the triggering of the SCRs driving the DC motor and measured the motor armature voltage during the period of the delay, thereby eliminating errors in the armature motor voltage caused by the SCR motor excitation.Alternatively, the current to the motor is measured to generate a pulse output for initiating an interval during which the measured armature voltage is sampled and transmitted to a summator for generating an error signal controlling application of power to the DC motor whereupon the aforesaid interval is terminated upon receiving a pulse indicative of power application to the DC motor.

Abstract: Method and apparatus for winding lengths of flexible material, packages produced by such method and apparatus, as well as endforms forming part of the mandrels on which such windings are formed, incorporate a number of winding parameters which are related to one another by a mathematical formula. Specifically, the mathematical relationship ##EQU1## where: A=the guide stroke,Gd=the guide distance from the spindle center line axis,G=the gain or advance of the wind,Dm=the diameter of the wind or coil, andYm=the wind or coil width;governs the shape of the walls of the endform and such end-forms are used in winding apparatus for producing wound packages of flexible material. From the above equation, the geometrical shape of the wound package can also be determined.

Abstract: A universal winding consisting of a plurality of successive figure-8s spaced radially around a mandrel with the figure-8s being spaced such that the crossovers exist in all but one location to form a payout hole extending from the exterior of the winding into the interior of the axial opening therein in which the speed of the traverse or speed of the mandrel is varied with respect to one another in such a manner that a greater density winding is obtained having a more uniform density, thereby enabling the winding to be compressed more uniformly around the diameter of the coil. A variation in the speed of the traverse or the speed of the spindle with respect to one another can be defined as either a plus or a minus gain and small changes in the gain place the crossovers such that the flexible material is wound more densely. The invention has particular application to large diameter winds in which relatively large diameter flexible material is wound.

Abstract: In a winding machine for the continuous winding of flexible material, first and second independently operable spindles are mounted in spaced relation in operative relationship with a traverse guide for feeding the flexible material. First transfer arms are mounted for movement in a vertical direction parallel to the axis of the first and second spindles for engagement with the flexible material being wound thereon and second transfer arms are mounted for horizontal movement between first and second spindles for engagement of the flexible material. The first and second transfer arms are controlled such that flexible material is transferred from a completely wound spindle to the other spindle for continuous winding.

Abstract: A package for a wind of flexible material wound with a universal wind and having a radial opening into the axial opening through which the inner end of the material is brought out is provided with specially shaped cones having end portions extending into the inner end of the radial opening to guide the material to prevent tangles and birdnesting during unwinding of the wound material. The end portions of the specially shaped cone members may be inserted into the end portion of the payout tube which, in turn, is inserted within the radial opening of the wound package.

Abstract: Method and apparatus for providing outside payoff from a wound package of flexible strip-like material wherein the package is mounted on a swivable support member through a radial hole in the wound material. The support member is mounted to enable oscillation about its longitudinal axis and the wound material is paid-off the package from its outer end by pulling it in a direction transverse to the longitudinal axis of the wound material and the support member. Tension forces may be provided to the support tube to prevent premature throw-off of the wind by controlling the oscillation of the package. Such tension forces may be provided by springs attached to the support tube or by mounting the support tube on a torque motor.

Abstract: A package for retaining material wound in a figure-8 configuration and including a radial hole extending from the central core space thereof to the outer periphery thereof is enclosed in a container having a preforated corner portion for feeding material from the winding. The winding is placed within a polygonally-sided insert having opposing sides engaging the outer periphery of the winding and including a feedout tube inserted in the radial hole for feeding the inner end of the material. Opposite sides of the insert engage the inner surfaces of the container with the feedout tube being aligned with the perforated corner portion. The bottom and upper surfaces of the container include intersecting cone sections for supporting the inner windings of the material.
