Abstract: A winder wherein, following completion of the winding operation, a roll receiver is moved from a standby position to a position under the completed sheet roll or rolls and the winding shaft used to wind the roll or rolls is then extracted to free the rolls for removal from the winder. Additionally, the winder is provided with a supply tension control for changing the tension in the web from that in the operation of unwinding the sheet from the web roll to a tension better suited for the winding operation, a winding torque adjuster which adjusts the winding torque by increasing the friction between the winding shaft and the winding core by regulating the air pressure within the hollow center of the winding shaft, and a winding core locking mechanism whereby the winding core is locked in place by spheres provided on the outer surface of a large number of core supporting collars fitted on the winding shaft.

Abstract: The centering and entrainment devices, by means of which the warp beam can be clamped or chucked, are axially slidably guided at side plates of the beam warping machine. With their outer ends they are hingedly connected at a respective lever. Both of the levers are pivotably mounted, by means of their one end about stationary pivot pins, in a plane which contains both of these pivot points as well as the axis of the warp beam. At their opposite ends both of the levers are interconnected by a rod arrangement, wherein a threaded sleeve having two opposite internal threads and rotatably mounted in one side plate allows changes in the length of such rod arrangement. Consequently, both of the levers can be synchronously and axially symmetrically moved towards and away from one another, so that the coaxially guided centering and entrainment devices can be symmetrically advanced towards and displaced out of the warp beam.

Abstract: The invention includes a first running web roll and a second new web roll to be attached to the first web roll as it is running, and means for pressing the second roll against the running first web whereby the second roll is caused to be rotated and brought up to the same speed of rotation as the first roll. The second roll includes a leading end, which is to be attached to the running first web, and which carries strips of double-sided adhesive tape which do not adhere to the first web until, at a desired time, means are operated to press the running first web against the second web. At this time, the tape secures both webs together, and the second web begins to run with the first.

Abstract: A roll, such as a cloth bolt, loader for a roll manipulating machine, such as a cloth spreader, which includes a pair of horizontally spaced lifting arms mounted to a frame and adapted to receive a shaft supporting a roll for elevation. The lifting arms are raised in unison such that the roll is elevated until the support shaft thereof engages a pair of horizontally spaced guide rails. The guide rails terminate on a down slope such that the roll and roll support shaft are transferred from the elevating lifting arms for free movement down the guide rails. The guide rails terminate in bridge tracks which yield downwardly under the weight of the roll and its support shaft for transfer of the roll support shaft down onto an underlying roll support of a roll manipulating machine.

Abstract: 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.

Abstract: The present invention is directed to a twin reel beltwinder which is designed to support an indeterminate length of conveyor belt for transportation within a mine cavity. The present invention includes a frame structure rotatably mounted on four wheels and including a framework for supporting a roll of conveyor belt. The entire roll of conveyor belt is initially positioned on one arm of the support structure. Subsequently, a portion of the conveyor belt is unreeled onto the second arm of the support structure. By equally distributing the conveyor belt between the first arm and the second arm of the support structure, the overall height of the apparatus is low enough to be accommodated within a mine cavity.

Abstract: Apparatus for lifting a reel from a supporting surface with the reel having centrally disposed axles projecting laterally from opposite sides. Upwardly inclined guide rails are supported in spaced, parallel relation with the upper surfaces of lower portions thereof engaging the under surfaces of the axles while the reel is supported on the supporting surface.
