  • Patent number: 4151906
    Abstract: An installation for the production of layered pressed panels and decorative panels, having a panel layer assembly unit and a transversely arranged press pack feeding unit, each unit featuring a horizontally extendable start-stop conveyor with a movable transfer frame whose belt guide rolls define an S-shaped belt run. The latter, while carrying a press pack, is extended over the receiving press pack feed conveyor, or panel press table, respectively, whereupon it is retracted from under the press pack, thereby gently depositing the latter, while belt clamps hold the conveyor belt in place, as the next assembly cycle takes place. The assembly of a press pack is performed by one or more layer collecting lines which pick up panel layers from layer stacks on opposite sides of the collecting conveyor of the layer assembly unit.

  • Patent number: 4149624
    Abstract: An endless conveyor belt apparatus is employed for moving raw materials which are characterized in having fines associated therewith from one point to another. The apparatus includes a silicone-emulsion spraying device for applying an aqueous solution of the silicone-emulsion to the material supporting side of the endless belt in sufficient concentrations to promote the release of the fines from the belt when the material being conveyed is dumped, thereby preventing the undesirable build-up of fines on return idler rolls and beneath the belt at points along the belt's return path.

  • Patent number: 4147249
    Abstract: Apparatus for distributing in single file and for spacing objects moving on a conveyor belt, including two vertically staggered chains. The chains are driven about pinioned shafts having axes perpendicular to the conveyor belt and each is provided with removable symmetrical fingers parallel to and overlying the belt. The fingers are spaced at predetermined distances on the chain, in accordance with the diameter of the objects. The fingers engage the object to, in effect, accelerate or slow down the object's motion to provide predetermined spacing between objects. The fingers engage the objects at points in a plane parallel to the direction of motion of the conveyor belt, whereby the stability of the object is maintained.

  • Patent number: 4147247
    Abstract: A stack former for rod-like articles includes a variable capacity transfer region between a supply conveyor and a stack conveyor. The supply conveyor is mounted on a unit which is pivotable to alter the capacity of the transfer region and which also carries a level sensor. The speed of the stack conveyor and the pivoting drive for the unit are selectively controlled by this sensor. The speed of the stack conveyor is also dependent on the angular displacement of the unit.

  • Patent number: 4146124
    Abstract: A pair of spaced and aligned driven bottle aligning belts is disposed to each side of a bottle feed path for coaction with bottles having necks, to facilitate movement of said bottles while on their sides and being fed along the feed path. The pairs of belts on each side of said feed path approach each other, in the direction of bottle feed, so as to narrow the feed path; and by doing so to align the bottles for subsequent processing. Pairs of spaced rails are disposed downstream in said feed path and to each side thereof to receive the aligned bottles as they exit the bottle aligning belts to maintain the bottles in aligned relationship until the bottles are fed into a twister which up-ends the bottles and directs them further along the feed path to work stations where they are cleaned, filled, capped, and otherwise processed. Suitable drive belts are provided for feeding the bottles along said feed path, with appropriate drives and controls to facilitate operation thereof.

  • Patent number: 4144964
    Abstract: A flexible support for supporting a conveyor belt of a conveyor having a frame. The flexible support includes at least one flexible element extending beneath a portion of the width of the conveyor belt, which flexible element is attached in the region of the ends thereof to the frame of the conveyor. The length of the flexible element is greater than the linear distance between the attached ends of the flexible element and the flexible element delimits support areas for supporting a portion of the width of the conveyor belt extending at least on opposite sides with respect to the longitudinal median plane of the conveyor. The at least opposite side support areas of the flexible element are responsive to the travel of the conveyor belt for being drawn in the travel direction independently of one another.

  • Patent number: 4141193
    Abstract: Apparatus for use with a pad stacking and packing machine for diapers or the like includes means for tipping vertical pad stacks on end and grouping two stacks together in a horizontal row or group of pads, with the group discharged as a unit into a shipping container. In one embodiment a conveyor with a vertical run and curved run picks up the pad stacks and turns them on edge and carries them to a grouping station where the stacks are accumulated into a group and the group is laterally discharged into a shipping container. In another embodiment, a turret which rotates about a horizontal axis receives the diapers in magazines arranged around the turret. The vertical and compressed stacks of diapers coming off the stack forming machine are loaded into the magazines at one position of the turret and the turret is rotated to position the pads on edge at the container loading station.

  • Patent number: 4141444
    Abstract: A sample transport mechanism is disclosed for conveying test tube samples in an endless path to and then away from a test station. The samples are removably inserted into elongated test tube supports arrayed upon a table in two rows and moveable in a rectangular path. Underlying the table is a plate generally coextensive therewith and having brackets mounting pins projecting above the margin of the table above and below the rows. The sample supports have parallel grooves in their bottom surfaces transverse to the longitudinal axis of the supports, and into which the pins may engage. The plate also has two openings, one square and the other rectangular, and into which are engaged cams. The cams when rotated move the plate in a rectangular path with respect to the table. The spacing of the pin and slots is such that the pins normally engage two diagonally opposite corner trays and move them longitudinally toward the next row by the incremental distance separating two adjacent samples.

  • Patent number: 4140014
    Abstract: The disclosure is of a friction drive wheel of the type employed for driving continuous conveyor belts. The wheel is lagged with a textile fabric which comprises a base of woven polyester yarn and a friction surface of polyester textile fibers needled to the base. The lagged wheels of the invention exhibit enhanced durability over prior art frictional drive wheels, reducing the down time of conveyor units incorporating them. In comparison to asbestos lagged drive wheels there is also a reduction of potential health hazards to operating personnel as will be appreciated by industrial health personnel.
