Abstract: A ''''balloon'''' is formed by an advancing yarn and is deflected to cause the yarn to be severed. In one environment, a tender patrols spinning stations of a spinning machine and automatically stops to service any of the stations requiring servicing which might occur, for example, because a bobbin being wound at the station is full. Upon stopping at a station, an operating assembly on the tender causes a yarn guide of the station to be retracted, and also causes a deflecting unit on the tender to deflect normal ballooning of the advancing yarn. This action, in turn, slows or stops a ring traveler which normally carries the advancing yarn about the bobbin, thus increasing the advancing speed of yarn while its withdrawal rate remains constant, and thereby severing the strand. In another environment, a supply bobbin is stationary and over-end withdrawal of the unwinding end at a generally constant speed causes the yarn to balloon transversely of the bobbin which facilitates faster unwinding. The balloon is deflected so that the yarn cannot be withdrawn as rapidly from the supply bobbin resulting in severing of the yarn.

Abstract: Apparatus for extruding plastic material comprising an extruder having a passaged junction box disposed adjacent an extrusion die is disclosed. The junction box incorporates a flexible junction plate which is positioned at the junction where diverse thermoplastic resinous streams of material merge or marry into a common laminar flow path. The flexible junction plate automatically adjusts its position in the common flow path of the diverse streams in response to the differential in the rates at which the diverse thermoplastic materials are fed through the common flow path to the extrusion die. By virtue thereof the junction where the diverse materials marry preliminary to coextrusion to form a composite sheet or laminate is smooth and linear. This promotes uniformity of relative thickness of the individual layers or laminae throughout the composite sheet. Moreover, since the adjustment of the junction plate is automatic as a function of the rate at which the several thermoplastic materials are delivered into the common flow path, there is no need to disassemble the extrusion apparatus to reset the junction plate when the rate at which the respective diverse thermoplastic streams are altered.

Abstract: A method and apparatus for forming a wound yarn package on a winder having a rotary traverse cam and a cooperating follower yarn guide for traversing a strand of yarn as it is wound onto the package. The winder is equipped to synchronize ribbon breaking, scattering, and shortening of the traverse stroke of the yarn guide, for slowly or rapidly winding a cheese (or cone) shaped yarn package usually with tapered end faces so that the package is suitable for very rapid over-end unwinding within tolerable yarn breakage limits, as on a ''''shuttleless'''' loom. A package drive roll is operated at constant speed and the traverse cam speed is varied in the neighborhood of 10 to 30 percent or more to provide a form of ribbon breaking and constantly varying high and low wind ratios. Scattering is provided at opposite end portions of the package for a length sufficient to avoid hard corners at the opposite end faces of the package. Traverse stroke shortening is not always required but, depending on the characteristics of the yarn, is generally desirable for tapering the end faces to deter stitching. Stroke shortening and scattering are accomplished by axial shifting of the rotary traverse cam. The ribbon breaking and scattering features are synchronized so that the sharpest yarn reversals are provided at the end faces with broader reversals immediately inwardly of these faces.

Abstract: A winder, such as a Model 959 take-up, manufactured by Leesona Corporation, Warwick, Rhode Island, has a rotary chuck mounted on a winder base and has chuck members resiliently urged into gripping engagement with a package core removably telescoped on the chuck. A lever is pivoted to the winder base and is operated in one direction by a fluid motor to release the chuck members from gripping engagement with the core. A brake member is pivotally connected with the lever in such a manner that operation of the motor in an opposite direction brakes the chuck and maintains the lever out of operating engagement with the chuck. The motor is controlled by a valve system which vents one side of the motor into the other side for positioning both the brake member and the lever out of engagement with the chuck.

Abstract: An apparatus and a method embodied in a guide for an advancing strand of yarn. The guide retains the strand on a receiver which is supported on a cushion of air. The receiver is pivotally retained between opposed members extending from a base of the guide. The strand urges the receiver toward the base and the cushion of air, which is introduced between the members proximate the base, urges the receiver away from the base. As the air is vented about the receiver the advancing strand is substantially out of contact with the air to prevent removal of coatings from the strand or entanglement of filaments of the strand. Response of the receiver to variations in the force exerted thereon by the strand may be programmed by regulating venting of the air about the receiver.

Abstract: Apparatus for segregating a jumbled mass of bobbins and delivery of the bobbins one at a time in axial orientation. A chain conveyor includes a plurality of buckets for receiving bobbins. These buckets open inwardly and together form the bottom of a hopper which receives the jumbled bobbins. As the conveyor is driven, a bucket receives a bobbin from the hopper and carries the bobbin upwardly along a substantially straight path to a discharge chute at an upper portion of the apparatus. The buckets have a particular cross-sectional configuration so that when they are on the straight upwardly extending path they will retain only one bobbin having a rounded cross-section and within a particular range of diameters varying from an empty bobbin core to a full bobbin. If a second bobbin is picked up by a bucket it will drop from the bucket along the straight path and fall back into the hopper. By varying the inclination of the buckets along the straight portion of the path, the range may be varied. A bobbin in the hopper may tend to align itself with its axis parallel to the direction of movement of the buckets and would thus block the buckets from receiving bobbins having their axes transverse to the path of movement of the buckets. Such a parallel bobbin is flipped over so that it falls back onto the hopper with its axis transverse to the path of movement of the buckets. Bobbins are fed into the hopper responsive to a reduction in weight of the bobbins in the hopper and the hopper is driven intermittently to deliver bobbins one at a time responsive to an external demand.

Abstract: Strand handling apparatus including a system for controlling a cycling carriage which scans and services bobbin winding stations on a spinning machine, or the like. The control system provides a signal indicating when a station being scanned is operational and service signals indicating when the station requires servicing. Upon receipt of both the operational and servicing signals the control system initiates a work cycle of the carriage to service the station. The service signals include both a full bobbin signal and a strand interruption signal. If there are more than a predetermined number of interruption signals during a cycle, the control system does not cause servicing of the stations responsive to this signal. If a roll-wrap occurs on a drafting roll of a station the strand is broken and does not enter the drafting rolls and the operational signal is not provided at this station so that the carriage bypasses the station until it is again placed in operational condition by an attendant. Upon starting-up with fresh bobbins at all of the stations, most of the stations would be ready to have their full bobbins doffed at about the same time, and the carriage would be overworked. Therefore, at startup the control system provides for doffing the stations in succession at timed intervals, and in conjunction with the operational and the servicing signals, to randomize the future doffing cycle of the stations.

Abstract: A system for automatically handling bobbins during processing of the bobbins. Various type of bobbins to be processed are stored in a supply area such as a spinning room where each type is separated into units of predetermined quantity. The units are automatically delivered by means of loading hoppers to suspended containers of a conveyor system for transport to bobbin processing apparatus. Following processing, the bobbins pass to another hopper and are returned to the containers and removed from the processing area to the supply area for additional processing such as stripping off residual yarn, sorting and refilling with yarn. A control system operates the handling system by discriminating between the conveyor containers each of which is designated for handling but one type of bobbin, and determining the condition of each container, whether it is empty or carrying bobbins and if it is carrying bobbins whether the bobbins are processed or are to be processed, and whether or not the hoppers are prepared to deliver the bobbins and the processing apparatus ready to receive a unit of bobbins.
