Feed Means Moved Out Of Engaging Position Patents (Class 226/35)
  • Patent number: 8319946
    Abstract: The present invention relates to a transfer device that can feed a work in a stable condition without applying it any excess loads. The transfer device for feeding a tape-shaped work to a process stage standing in an upright position, which is placed on one side of the process stage and which includes a supply reel, a take-up reel and a work feeding mechanism. Specifically, the supply reel, around which the work and a protective sheet are wound, is adapted to feed the work and the protective sheet therefrom. The take-up reel is adapted to wind the work and the protective sheet that have been fed from the supply reel, and it is located below the supply reel. The work feeding mechanism is adapted to forward the work from the supply reel to the take-up reel through the process stage.

  • Patent number: 6334563
    Abstract: A retensioning device for strapping machines is provided with a pair of tape tensioning rollers comprising a stationary counter roller and a pivoting roller which can be adjusted towards it. A strapping tape is guided through the nip and via an angle of wrap round the pivoting roller. The pivoting roller is mounted on a pivoting lever which can be loaded with a defined force. The retensioning force building up in the strapping tape is opposed to the loading force in such a way that the pivoting roller lifts momentarily from the counter roller when the loading force is exceeded and therefore interrupts the retensioning process.

  • Patent number: 5660676
    Abstract: An improved laid-on labeler is designed for substantially increased operating speeds when compared to prior art systems. The labeler includes an articulating labeling arm with a label peel blade. The labeling arm is attached to a support structure at a pivot point immediately above and below which are a respective pair of deflecting idler rollers through which a continuous label web is fed. With the label web being supported at the pivot point of the labeling arm, torque on the labeling arm from starting and stopping the label web is minimized. The label web passes between a drive roller and respective nip rolls on both a pay-out and a take-up side which relieves differential tension on the label web as it passes over the peel blade, thus minimizing or eliminating tearing and breaking of the web as drive speeds increase. Control is via a PLC, which also controls a variety of optional features.

    Abstract: An apparatus for measuring and controlling lengths of movement of a continuous stock material strip which is intermittently fed by feed rollers along a predetermined path of travel to a machine which includes a reciprocally operable carriage having tooling for acting upon the strip. The apparatus comprises a strip measuring mechanism for engaging with and sensing a length of movement of the strip and generating a first signal representative of the length of movement of the strip. A controller receives the first signal from the strip measuring mechanism, and comparing the first signal to a second signal representative of a predetermined desired length of movement of the strip. The controller generates a shut-down signal to the machine if the difference between the first and second signals exceeds a predetermined shut-down limit range and generates a length error signal representing the difference between the first and second signals.

    Abstract: A splice detection apparatus which operates directly upon the solenoid which is conventionally used to bring the pinch roller into contact with the capstan of a recording/playback unit, eliminating the need for separate levering mechanisms, to detect changes in thickness between spliced and unspliced portions of a tape. Such differences are monitored directly at the solenoid, resulting movement of the plunger of the solenoid developing a change in voltage which is detected by appropriate electronic circuitry to develop a signal which indicates passage of the splice, and appropriately discontinues transport of the tape.

  • Patent number: 4401250
    Abstract: In the intermittent forward feeding of a material web provided with transverse crease lines and simultaneous punching of holes into the material web in a definite relation to the crease line pattern, it is important to ensure that any faults in the length of the forward feed, do not accumulate during working over longer periods. Such faults, which occur due to unavoidable inaccuracies would lead successively to ever increasing faultiness in the placing of the holes. A method and an arrangement adapted to avoid the accumulation of such faults are provided.In the method the material web during each forward feeding is advanced a distance which exceeds the correct distance between two transverse lines by the fault margin. Subsequently, before the next forward feeding, the web is restored to a correct position, not affected by any faults in the distance between the crease lines.

  • Patent number: 4364505
    Abstract: The invention relates to a hydraulically actuated feed roll lift mechanism for feeds utilized to feed strip stock into a machine, such as a mechanical press. Regulated hydraulic pressure acting against a piston that is connected to one of the feed rolls through a yoke forces the feed roll against the stock to grip the stock and cause an increment thereof to be fed into the press when the rolls are rotated. A roll opening cam, which is connected to the press crankshaft, advances a small piston to displace oil against the other side of the piston while the stock is at rest to thereby separate the rolls during the time that the dies are in contact with the stock in the press. The time at which roll separation is initiated is controlled by adjusting the angular position of the cam on its shaft, as by releasing a frictional lock mechanism, rotating the cam to the desired position, and then again locking it in place.
