  • Patent number: 4344584
    Abstract: Apparatus for winding webs from a large-diameter roll onto cores to form smaller diameter rolls wherein the cores are supported on mandrels mounted at one end on a turret that is indexed between a core loading station, operational stations including at least a web winding station, and a wound-web unloading station. A pair of axially spaced star wheels keyed to a freely rotatable shaft having its axis parallel to the axes of the mandrels sequentially are engaged by, are rotated by, and are disengaged from a mandrel as it is moved between the core loading and winding stations to ensure alignment of the free end of the mandrel for supporting engagement with a provided latching cup operative to engage and steady the mandrel in the operational stations.

  • Patent number: 4335442
    Abstract: A synchronous oscillator demodulator for linear variable differential transformers and synchronous resolvers having electronic circuitry designed to digitally construct a preferred waveform of a predetermined frequency and to establish precisely the preset point at which the amplitude of the waveform is to be measured at the secondary winding of the transformer. This synchronous oscillator demodulator permits the use of linear variable differential transformers and synchronous resolvers for high frequency applications and under conditions of noise and vibration while still maintaining a high degree of accuracy and repeatability. A system and apparatus to enhance the signal from a given linear variable differential transformer and tune same in relation to the signals of other similar but not identical transformers is disclosed.

  • Patent number: 4332756
    Abstract: Method for the manufacture of a fibrous web comprises provision of a conduit having a plurality of outlets for discharging classified fibers onto a linearly movable planar section of an endless screen. The fibers pass through openings in the screen and land on an underlying planar section of a forming wire, in formation of the fibrous web, with the aid of an underlying vacuum box. Uniformity of fiber distribution is provided by parallel banks of brushes that engage the planar section of the endless screen and are rapidly oscillated in short, non-synchronous strokes transversely of the direction of screen movement.

  • Patent number: 4332324
    Abstract: The tail of a roll of fibrous web material is secured to underlying layers through penetration of the layers by a row of needles extending tangentially of the roll and in the same direction that the tail extends or is presented. Penetration is to a depth of about 6 layers, and is accompanied by punching out a very small tab of each layer and pushing it into the opening of the successive, underlying layer thereby to lock the tail in place. Pulling the tail to unwind layers from the roll pulls the tabs from succeeding layers in the direction of unwinding, without tearing the outer layer.

  • Patent number: 4331730
    Abstract: Apparatus for the deposition of a uniform web of dry wood pulp fibers on a forming wire in combination with melt blowing die means operable to deposit melt blown fibers on the web of dry fibers to strengthen the web. Means for depositing the webs comprise serially disposed sets of fiber distributors, and the die means is disposed between the sets of fiber distributors so that the melt blown fibers are deposited as separate layers on the finished web.

  • Patent number: 4323748
    Abstract: Disclosed is a method of transferring energy from a stationary generator of power at radio frequencies to a rotating work station such as a coil to heat inductively by selectively connecting the generator as the work station rotates past the generator. A pair of stationary contact strips connected to the generator are used to connect the low voltage, high current radio frequency (RF) energy to the rotating machine. The contact strips are a commutating device in that they can intermittently be connected to a series of brushes or contactors carried by work stations requiring power. The contact strips form a closed loop which shunts the energy at the point where the brushes engage and/or leave the contact strips thereby keeping the current flow to a minimum at those points. As the brushes slide across the contact strips they move from the shunt to the power input points on the contact strips and where the current flow increases because the voltage difference between the strips is the greatest.

  • Patent number: 4319870
    Abstract: Apparatus for manufacture of fibrous webs including means to spray adhesive binder particles onto a fibrous web supported on a forming wire includes spray heads in a spray booth through which the wire passes, and a pair of baffles extending transversely of the plane of the web, at opposite sides thereof. The baffles and portions of the booth are relatively closely spaced from the web, to form elongate openings below the plane of the web. A suction box having an opening beneath the web and forming wire draws air through the web and wire in a pair of flow paths that lead upwardly through the elongate openings between the baffles and the web, then downwardly through the web and the wire. The air drawn upwardly between the baffles and the web prevents sprayed-on particles of binder material near sides of the web from escaping and contaminating adjacent portions of the apparatus.

  • Patent number: 4318263
    Abstract: Apparatus for inserting a film-wrapped package into a carton. A relatively flat film-wrapped package, sealed along a peripherally extending flange that projects away from its contents, is inserted into a carton through an open side having closure flaps. To ensure against interference of the flange with the closure flap upon closing the carton, the package is inserted using a pushing device having a concavely curved face engageable with the package flange, and operative to curl the flange into the carton for frictional retention by a wall of the carton.

  • Patent number: 4313767
    Abstract: A method and apparatus for cleaning particulate matter from container bodies. Container bodies are conveyed, open end down, along a corridor formed by two parallel pressurized fluid curtains. The container bodies pass over a series of nozzles which subject the interior of the containers to blasts of ionized gas. The ionized gas neutralizes any electrostatic charges and expells the particulate matter from the container. The curtaining sweeps the expelled particles into a spray mist region where they are entrained and subsequently condensed into a waste stream for disposal. The apparatus features a tunnel which substantially separates the fluid curtaining from the spray mist region. An outer housing enclosing the spray mist region is fabricated of transparent plastic to permit visual monitoring.
