    Abstract: Apparatus for sensing the presence of an object, such as a machine operator, in the path of 1 travelling tender is disclosed. The tender is movable by drive means relative to a strand processing machine and incorporates a source of electrical energy and means in circuit with the electrical energy source to provide a modulated output signal. Radiant energy emitting means are provided for receiving the signal and providing a radiation output proportional to the signal. Radiation sensitive means for receiving the output from the emitting source and transmitting a control signal in response thereto is also included. The control signal is measured by a comparator and gating means are connected with the comparator, the gating means being in a normally nonconductive state. The gating means is switched to a conductive state to program the tender drive means to a zero speed state to program the tender drive means to a zero speed state when the amplitude of the control signal drops below a predetermined value such as, for example, when the operator interrupts the output signal from the output signal producing means. In consequence thereof the travelling tender is halted without injury to the operator.

    Abstract: Two photocell detectors are spaced along a path of a moving strand with a gap of known fixed distance therebetween. The photocells view a length of the strand on each side of a knot or defect in the strand when the knot is presented in the gap. An inspection cycle is started by entry into the detectors of a knot or defect and a defective knot or defect is determined by comparing the dynamic signal status of a photocell spaced some distance behind the knot with the signal taken from a photocell ahead of the defect and stored. The existence of a signal at this position or of an exceptionally large signal indicated by comparison at the time of initiation of the cycle indicates the presence of a defective knot.

    Abstract: Continuous process and apparatus for bulking textured yarn includes combining a plurality of strands of the textured yarn into a continuous tow, forming the tow into a continuous series of loops, moving the looped tow through a bulking zone, setting the bulked tow, separating the tow into individual bulked strands, and collecting the strands into packages. The bulking chamber includes a plurality of positively driven screw-like members, which advance the tow through the chamber under bulking conditions at a predetermined rate. In one embodiment the tow is delivered into the chamber through a course which includes forming the tow into relatively large loops which are permitted to shrink and thus bulk promptly upon introduction into the bulking zone. The bulking zone includes controlled conditions of temperature and humidity. In another embodiment the tow is first subjected to a preconditioning step within the bulking zone and thereafter is bulked while being relaxed under controlled conditions in the bulking zone. Subsequently, the bulk is set in a separate zone by dry heat.

    Abstract: Supply bobbin delivery mechanism including a rotatable divider mounted on an axis within a tub-like bobbin container is described. The divider includes a plurality of separators, the space between each adjoining pair of separators forming a bobbin receiving compartment. The divider is driven by an indexing mechanism having at least as many positions as there are separators thereon. The container is mounted in an inclined plane and has an opening at the high point along its periphery. The container is charged with bobbins by automatically or manually filling each space or compartment. On demand from the user mechanism the divider is indexed one position at a time. Consequently, bobbins in each compartment are moved sequentially into alignment with the opening in the container whereupon these bobbins slide downwardly under the force of gravity to the user mechanism. Indexing of the divider to thereby deliver a fresh quantity of bobbins from the next succeeding compartment to the user mechanism is repeated on each occasion when a demand signal for supply bobbins is received.

    Abstract: Automatic servicing apparatus for spinning stations of one or more spinning frames includes provision for severing and clamping roving to stop feeding of the roving and to present a cleanly severed supply end of the roving in convenient position for subsequent thread-up. A carriage patrols the spinning stations and stops at any station requiring servicing, whereupon mechanism on the carriage doffs the bobbin being wound at the station, donns an empty bobbin core and normally starts the yarn spun from the roving winding onto the empty bobbin. If a station cannot be adequately serviced by the carriage mechanism a signal initiates operation of a scissor on the carriage and as the scissor is moved to an operative position for cutting the roving upstream of the drafting roll stand a roving clamp clamps the severed end of the roving extending from the roving supply. The scissor is then retracted and the station is rendered inoperative by the prior movement of a target on the clamp to a position in which a photo responsive sensor is not actuated so that the carriage subsequently by-passes the station.

    Abstract: Winding apparatus, such as a Model 959 take-up machine, manufactured by Leesona Corporation, Warwick, R.I., has a base on which a spindle frame is pivotally mounted for receiving a yarn package and urging the package against a roller bail mounted on the base. As the package increases in diameter during winding, the spindle frame is progressively moved away from the roller bail which continues to engage the face of the package. The package may tend to bounce or otherwise move away from and toward the roller bail for various reasons, such as an eccentricity in the longitudinal face of the package developing during winding or caused by an eccentric package core. A friction type dampener is provided for dampening such movement of the package on and off of the bail. This dampener has a frictional dampening part fixed to the base and movably secured to the spindle frame by a leaf spring having one end fixed to the dampener and the other end secured to the spindle frame to eliminate any play therebetween in the direction of movement of the spindle frame toward and away from the roller bail, while permitting relative movement between the spindle frame and the dampener. Frictional retardation provided by the dampener is adjustable.

    Abstract: A machine for winding electrical coils in ''''gang'''' style on an elongated arbor. The machine includes serving means for inserting a sheet of paper or other insulating material automatically between each successive layer of wire in each of the coils on the arbor. Each sheet is cut automatically to a length sufficient to wrap around the then-existing layers of wire in the coils, each sheet overlapping slightly at its beginning and terminal ends. Means are provided to commence serving each sheet at the same relative location on each coil, thus causing all the overlaps to occur at the same radial location on the coil. A generally elliptically shaped coil is formed.

    Abstract: A spinning frame has a plurality of stations for spinning roving into yarn and winding the yarn onto a bobbin. A tender moves passed the stations and stops at any of the stations requiring servicing such as, for example, doffing a filled bobbin and donning an empty bobbin. The tender then continues patrolling the stations until it comes upon another station requiring servicing. As the tender patrols the stations, a first sensing device on the tender scans the stations to determine whether or not the yarn is advancing normally and provides an appropriate signal. A signal from a second sensing device indicates whether or not the station is operational. The signal from the first sensing device is combined with the signal from the second sensing device to stop the tender only at an operational station requiring servicing, whereupon the servicing cycle commences. At the end of servicing, if the yarn is advancing normally the tender resumes its patrolling. If the yarn is not advancing properly, another servicing cycle is commenced. Thereafter, if the yarn is still not advancing properly, the roving is automatically broken above the usual drafting rolls of the station as a signal flag is positioned to indicate to the second sensing device that the particular station is non-operational. The tender is not stopped at a non-operational station. The two sensors may both be phototransducers. The first sensor provides a particular fluctuating signal responsive to a transverse alternating motion of the yarn which results from ballooning of the yarn as it is advanced longitudinally while being wound onto the bobbin, and this signal results in the tender passing the station and continuing its patrolling. All other fluctuating signals from the first sensor, such as may be caused by ambient light, either day light or artificial light, for example, as well as signals resulting from movement of the tender while patrolling the stations, are filtered out.
