A spool-handling dolly consisting of a simple U-shaped chassis mounted on wheels and arranged to be wheeled over a floor surface. The chassis has an upright post and slide, along which there is movable a carrige that is raised and lowered by a drive means comprising a vertical screw and a handwheel. The wheel has a lifting shoulder or projection which is adapted to be inserted in the bore of a filled spool that is positioned with both its flanges resting on the floor surface. The carriage also has a clamp jaw adapted to cooperate with the lifting shoulder in a manner to clamp an upper portion of one of the spool flanges securely to the carriage. A guide means on the carriage enables the clamp jaw to be vertically adjusted for this purpose. There is a second drive means on the carriage, engaged with the clamp jaw for moving the same along the guide means in its vertical travel. After the second drive means has been operated to clamp the spool securely to the carriage, the first drive means is operated to raise the carriage so as to lift the spool completely off the floor surface. The dolly and spool can then be wheeled to the desired location. The carriage includes an over-arm, at the extremity of which there is a pay-off pulley located to receive wire that is uncoiled from that end of the spool which is not clamped to the carriage.
An apparatus for winding or unwinding of a cord-shaped material, e.g., of electrical cables, steel cables, or ropes, on and off a spool. The apparatus has two downwardly pointing arms, the lower ends of which each carry a sleeve for receiving the spool. Since the exchange of particularly heavy weight spools previously was time consuming and physically very strenuous, whereby in addition a great danger of injury exists for service personnel, for the elimination of these disadvantages the invention provides that about a horizontal axis at least one of the sleeve arms is able to be swung up out to over the space assumed by a spool which has been set on the floor, and the apparatus is open on the side of the swingeable-up sleeve arm to an extent facilitating a relative movement of the spool and the apparatus.
A positioning and splicing device for paper rolls having at least one carriage arranged to be movable along guides and having an upright on one side provided with slide members for guiding a second carriage that is axially movable along the upright. The second carriage is provided with a spindle for engaging a roll. The roll is raised by a movement of the spindle protruding from the roll and the carriage is moved into engagement in a rotary coupling element that is fixedly mounted, so that the spindle is supported at both ends when the sheet is un-wound from the roll.
The strip decoiler of the invention has a dancer arm in a vertical plane which sets the speed of the decoiler turntable. The lower end of the dancer arm mounts an adjustable connection which in turn supports a spool shaft carrying a support spool. The spool shaft can be swiveled about so that the spool can support the decoiling strip evenly all across its width. The shaft is quickly and easily adjustable for use with clockwise or counterclockwise uncoiling.
A transport cart for material carriers such as bobbins or drums having threads or other elongated material wound thereon, has a cart frame with wheels and a tilting frame journalled in said cart frame. The tilting frame carries two parallel skids for supporting a material carrier on its rollers. The tilting frame is tiltable between a first position in which the skids extend horizontally for loading a material carrier onto the cart, and a second position in which the skids extend vertically for unloading a material carrier, or vice versa.
A sub-system for controlling the flow of cable pulled from a cable pack by an automatic cable processing machine. The sub-system may include a barrel cap for containing and controlling the outward momentum of the cable over a cable pack such as a barrel and guiding the cable through a passage in the top of the cap. The passage is positioned in line with a center line of the barrel. A variable rate braking system may be positioned over the barrel and adjacent an outer wall of the barrel to control the circular movement of the cable as the cable is unwound from the barrel. A spacer may be positioned to prevent the cable from being pulled towards the center of the barrel or toward the barrel core and so that the cable engages the variable rate braking system. The system prevents cable from overlapping, entangling, knotting and snapping during the automatic processing of the cable for use in wire harnesses.
