Disclosed is a drive apparatus for a device for applying paraffin wax to yarn. In the device, a solid block of paraffin is mounted on a polyhedral bolt which is driven by a whorl or drive pulley. The whorl, in turn, is driven by a continuous drive belt. Advantageously, a plurality of similar devices are mounted on the same open-end spinning machine so adjacent devices may be driven from the same drive belt. Bracing elements hold the yarn against the rotating face of the paraffin block of each device to ensure uniform application of paraffin.

There is described a two-for-one twisting spindle having a supply receptacle for a lubricant arranged in a base of a protective pot, a region of an outer circumferential surface, of the protective pot, over which the revolving thread passes when the spindle is operating, communicating with the supply receptacle in such a way that lubricant is brought to the said region of the circumferential surface. Thereby the supply receptacle is in a stationary part of the spindle, so that lubricant content in the receptacle has no inertial effect on the running of the spindle. The arrangement enables consistent but not excessive wetting to be provided for the thread without the thread being subjected to undesirable stresses while the spindle is operating. In the arrangement shown, a protective pot 4 has a sidewall 5, over which thread 16 passes when the spindle is operating, and a base 7 having a cavity holding a supply of lubricant 10. Projecting into this cavity is an annulus 11 of absorbent material or material having a capillary structure, this annulus 11 extending through a circumferential slotted opening 15, whereby the thread fed past the outside edge of the annulus is wetted.

A device for waxing a yarn in a spinning machine which includes an annular wax roll, and means for rotatably supporting the wax roll. The support means includes a solid cylindrical member integrally connected to the wax roll so as to project from one end of the wax roll, and a support spindle associated with the cylindrical member for allowing the integral rotation of the cylindrical member and the wax roll. The waxing device is disposed that the yarn, which travels from a supply of yarn to a yarn winding-up mechanism, contacts both the projected periphery of the cylindrical member and the one end of the wax roll. The rotation of the wax roll is caused mainly by the yarn contacting the solid cylindrical member so that the wax roll is not adversely affected by the yarn even when changes occur in the travel condition of the yarn, so that no grooves or concaved lines are formed in the end face of the wax roll.The wax roll can be retracted from an operative or waxing position, in which the yarn contacts the wax roll during the normal spinning operation, so that the wax roll is kept away from the yarn during a yarn piecing operation and doffing operation, thereby removing factors which cause the irregular rotation of the wax roll and the formation of grooves in the end face of the wax roll.Additionally, the waxing devices can automatically bring the yarn into a proper waxing position, in which the yarn is in contact with both the wax roll and the solid cylindrical member, after the yarn piecing operation and the doffing operation.

In a process and apparatus for manufacturing drawn and twisted multifilament synthetic yarn an extruded and partially drawn filamentary synthetic yarn is subjected to a supplementary, simultaneous, drawing and twisting operation using a double twist spindle rotated such that the tension in the yarn causes drawing. After the spinning and drawing, the yarn is subjected to heat treatment under controlled tension and is then wound up.

A false twisting unit consists of a body through which a passage is provided, which is surrounded by a cavity connected with said passage through tangential air ducts. A first channel passes through said body and opens into said cavity. Through said channel compressed air can be supplied, producing a rotating air column in the passage. A second channel passes through said body in such a way that liquid at or near the mouth of the tangential air ducts can be introduced into said passage.

A device for distributing softening liquid to a yarn, when the yarn is being balloon twisted and has emerged from the spindle or core of the spindle including a container for the balloon, at least one chamber integrally fixed to an external portion of the container wherein the balloon slides, at least one feeding means for supplying liquid to said chamber and at least one porous seepage septum, which is present as an inner sliding surface for the balloon. The chamber is fed with liquid under adjustable pressure.

A process for continuously bonding hydrophilic staple fibers into a stable band wherein an excess amount of liquid containing an adhesive distributed therein is applied to a fiber arrangement formed of staple fibers, excess liquid is squeezed off, the fiber arrangement is compacted into a compact band by pressure, and the adhesive in the band is set by feeding the band into or bringing such into contact with a condensing vapor atmosphere.The stable band produced according to the aforementioned process is manifested by the features that such stable band, compared to a stable band having the same quantity of adhesive and set in dry air, possesses a greater breaking length and a better distribution of adhesive over the cross-section of the stable band.
