Abstract: A receiver for supporting one end of a bobbin tube in a spinning or bobbin winding machine has a tube-engaging plate member with a nose member mounted on the plate member for movement between a normal resting position and an operating position A yarn delivery device guides the yarn into the range of movement of the nose member. A contoured yarn clamping surface and a contoured yarn guide surface are formed on the plate member. The nose member initially catches the yarn and clamps it on the clamping surface, drawing the yarn end out of the delivery device, and then guides the yarn via the yarn guide contour in the direction of the middle of the bobbin tube. The nose member is thereby surrounded by a loop of the yarn and extends over the foot end of the tube in the direction of lengthwise the middle of the tube to orient the yarn loop adjacent to the winding area for the yarn reserve windings.

Abstract: The disclosure describes herein a box within which is mounted a reel having a supply of wire, cable or the like to be dispensed. An opening is provided in one of the walls of the box to allow the egress of one end of the strand. A cover securely contains the reel within the box. Also mounted within the box is a brake device which has a portion slidingly contacted by the strand prior to egressing from the box. An external pull on the strand frees interengageable elements on the brake device and on one of the side plates of the reel from blocking rotation of the reel in one direction. As soon as a pull is no longer exerted on the strand, a resilient element on the brake device urges the elements to interengage to thereby stop rotation of the reel.

Abstract: A stair relief device is positioned around connecting plugs, splice or the like to relieve the contained plugs, splice or the like from any tension which is in the cord. It consists of a rigid hollow cylinder having two rigid circular flanges, extending outwardly at opposite ends of the cylinder. Each of these flanges has positioned therein two slots of appropriate size and shape to permit an electrical cord to pass through the slot. On each flange the two slots are positioned one hundred and eighty degrees (180.degree.) around the flange from each other. The slots in each flange are aligned directly opposite the slots in the other flange. The section of the cord to be protected is positioned within the cylindrical portion of the device. The cord at either end of the device is then positioned back through the slots in the flanges and turned at least one hundred and eighty degrees (180.degree.

Abstract: In a spun yarn forming textile machine, when a spun yarn delivered from a yarn forming device at a predetermined constant speed and a yarn withdrawn from a yarn package are pieced to each other, a splicer is used to piece together the yarn. After withdrawing a yarn from a yarn package with a predetermined length, the yarn piecing operation is carried out. Rotation of the yarn package is started before the yarn piecing operation is completed. Therefore, snarling can be prevented and the construction of the yarn storing means can be simplified.

Abstract: A method for producing a coreless coil of strand-like material in which the strand-like material, which may be wire, insulated or non-insulated cable, glass fiber or the like, is wound in several layers on a substantially cone-shaped winding spool. The layers are inclined with respect to the longitudinal axis of the winding spool. The first pair of layers each contain N.sub.1 windings. The second pair of layers each contain N.sub.2 =N.sub.1 +.DELTA.N windings, where N is a constant value. In this manner, the number of windings for consecutive layer pairs is increased until the total number of possible windings for a predetermined winding pitch is reached. The layers of each pair are wound by a take-up apparatus that moves in a first direction for winding one of the layers of a pair and in a second opposite for direction for winding the other layer of the pair. A coreless coil produced by such a method, an apparatus for carrying out the method, and an apparatus for unwinding a coreless coil also are disclosed.

Abstract: In a traveling wire take-up method and machine of a wire coating line, a wire shifting guide lever of a take-up machine shifts a traveling wire toward a snagger of a bobbin holder to change over from a presently take-up bobbin to an empty bobbin. A take-up tension of the traveling wire is increased before the changeover operation, and the take-up tension of the traveling wire is reduced to a predetermined take-up tension after the changeover operation has been finished. Furthermore, increase and decrease of the take-up tension is preferably controlled by adjusting an output of a sheave motor in a dancer roller disposed in front of the take-up machine.

Abstract: A gimbaled compliant guide for tape drives includes two plates mounted adjacent opposite edges of an arcuate tape bearing surface. The plates are pivotably mounted to accommodate variances in the tape path resulting from tape path tolerances and tape distortions. One plate is also mounted to a leaf spring to accommodate variations in tape width. The combination of simple compliancy and the ability to pivot eliminates the concentration of the stress at a single contact point between the tape edge and the guiding mechanism. By evenly distributing the stress along the span of contact between the edge of the tape and the guides, particulate matter generated from such contact is minimized. Such guiding mechanism may be used on any element of the tape path.
