  • Patent number: 5367857
    Abstract: Feedstuff is compacted in a tube which lies on the ground by a mobile device which includes a traction vehicle, a trailer unit, and a rotatable feeding screw mounted at the rear of the trailer unit for feeding feedstuff from a container into the tube where it is compacted. The screw is rotated by a hydraulic motor which is driven by hydraulic fluid at a pressure which is proportional to loading of the feeding screw due to compaction of feedstuff by the screw. A brake system brakes the wheels of the trailer unit to produce a braking force while the feedstuff is being fed into the tube. A control unit controls the brake system in response to signals from a transducer which senses the hydraulic pressure at the motor. The braking force is reduced when the sensed hydraulic pressure rises to a predetermined maximum value, and the braking force is increased when the sensed hydraulic pressure decreases to a predetermined minimum value.

  • Patent number: 5016424
    Abstract: A compressed (e.g. accordian pleated) assembly of tubular sheet material (preferably plastic material), is deployed to form an extended tube by a device that consists essentially of an arched rigid framework (curved, triangular, rectangular, or any other shaped arch suited to the shape of the goods to be stored) with a skin of sheet metal or fiberglass extending over its upper part. The tubular sheet material can be deployed into an extended tube at the rear of the device by pulling the latter forwardly along the ground, the free end of the tube having been suitably anchored at the starting location. This tube deployment can be combined with a series of loading operations whereby goods to be stored, e.g. cylindrical or large square bales of forage, are inserted from the front of the device through the arched framework and onto a lower portion of the extended tube as it is formed. This lower portion rests on the ground in a loading area beneath a rearwardly extending overhang of the framework.

  • Patent number: 5009632
    Abstract: A transverse-welding station [(12)] is provided for joining the hose parts [(11a, 11b)] of foil hoses [(11)] that are welded to bag lengths [(BL)] by transverse welds [(21, 22)]. In this station, the hose parts are superimposed such that the joining weld is laid exactly on the superimposed transverse welds [(22) ] of the two hose parts. This results in a joining of the hose ends that does not use adhesive tape and observes the pitch determined by the length of the bags. The invention provides a joining that is practically imperceptible and does not at all impair the quality of the bags made. In particular, the occurrence of single bags that would have to be considered as waste is avoided. The method is applicable for cutting out imperfections from a foil hose, as well as for connecting the beginning of one hose roll to the end of the preceding hose roll.

    Abstract: The packing of a tubular casing segment which has been shired together into a hollow cylindrical shirring formation occurs in a tubular net of such configuration that first, with the shirring accomplished with the aid of an abutment which is movable on the shirring tube, a certain initial segment of the tubular casing length is allowed to be left unshirred. Following termination of the shirring, the shirring tube is withdrawn with the abutment from the tubular shirring formation, and the unshirred tubular casing length segment is narrowed down or swaged and is sealed. Finally the sealed tubular casing length tip is inserted with force into the shirring and together with the shirring is thrust through a cylindrical carrier, in which a tubular net is recovered which is sealed to the tubular shirring. This is turned inside out with the thrusting through of the tubular shirring and surrounds this part along its entire length.

  • Patent number: 4945715
    Abstract: A bale bagging apparatus for bagging round bales in tubes of plastic film includes a hoop and an annular flexible tube support projecting to the rear of the hoop. The tube support conforms to the shape and size of the bales being bagged, so that a tubing may be used that is fairly close in size to the size of the bales. This reduces the amount of air inside the bag and the ultimate looseness of the bagging tube on the bale, which affects its wind resistance and allows the bagging of bales in smaller tubes, which significantly reduces the cost of plastic film.

  • Patent number: 4926616
    Abstract: A mechanism packaging tape cassettes in cardboard sleeves including a controlled cassette guideway which advances cassettes to a packaging station and a controlled loading track which advances sleeves to the packaging station for positioning on the cassettes. The guideway may either receive cassettes from an incoming belt or a hopper. A pusher mechanism advances the cassettes to the packaging station while a retractable stop insures proper location of the cassette. The cassette is slightly raised above the surface of the guideway to be properly positioned for receiving the enclosing sleeve. The loading track includes a hopper to receive collapsed sleeves. The sleeves are released one-at-a-time into the loading track where a sleeve pusher advances the sleeves one-at-a-time into a die defined by opposed channels. The channels are spaced such that the continued pushing of the sleeve therethrough causes it to assume its appropriate rectangular configuration.

  • Patent number: 4914893
    Abstract: A banding apparatus for automatically forming bands from flattened tubular banding material and applying them to large sized containers. A set of inner crease rollers disposed on a floating wedge inside the tubing interact with outer crease rollers to press out sidewall creases during formation of cylindrically shaped bands. The wedge comprises a pair of parabolic or variable width separation plates joined at right angles along a common axis and using a mounting block to support the inner crease rollers. A feed assembly in the form of a reciprocating slide assembly releasably engages the banding material using a contact lever and advances predetermined lengths of the banding material to a cut-off assembly above the containers where they are cut into separate bands. A support head positioned adjacent to the cut-off assembly engages and holds a portion of each band in a fixed vertical position above the containers which suspends them in an open configuration for engagement by individual containers.
