Abstract: A reel cutting and winding machine for longitudinally cutting a sheet into strips and for winding up the strips on winding cores into separate wound packages. Stationary mounting plates are mounted at either side of the machine, and a cross-member is pivotally mounted between the plates. The cross-member is pivotable into a winding position, a wound package sealing position, and a package depositing position. Lever means is operatively connected to the cross-member and carries the winding core. Carrier levers are pivotably mounted between said plates for movement between a waiting position during the winding process and a second, operating position for cutting the sheets transversely when a roll formation is complete. Adjusting levers are pivotably mounted on said carrier levers means and are adjustable independently of said carrier lever means.

Abstract: An apparatus for winding a continuous web, specifically tear-resistant paper or cardboard web, is preferably designed as a Pope reel winder, and when exchanging a full roll with an empty reel-spool, the latter is in customary fashion placed on the winding drum over which the web initially continues to advance onto the full roll. At the edge of the web, a sickle-shaped catch lever reaches around the upper portion of the empty reel-spool and engages the edge of a web loop to pull it about a portion of the empty reel-spool. Simultaneously, a cutting device can make a transverse cut in the edge of the paper web, and once the web edge has been engaged by the empty reel-spool, the remaining portion of the web tears through essentially without any shock effect.
Abstract: Apparatus and method for starting respective leading ends on web running continuously and would into successive rolls, such as paper. As each roll reaches a final diameter, a fresh leading end is provided on the web by slitting in a generally cross-machine direction from a leading starter tongue projection extending downstream. The starter tongue projection with the fresh leading end of the web is directed into winding relation onto a fresh rotary core for winding of the web into another roll. This is adapted to be effected automatically and without interruption of high speed web travel and successive roll starting and winding.
Abstract: In web rewinding apparatus for producing hard-wound individual rolls, a knife for cutting through the web is carried for substantially radial extension and retraction by a cutoff roll which cooperates with a bed roll around which the web has substantial wrap. When extended, the knife enters a longitudinal slot in the bed roll, in which there is a row of fixed pins. A web impalement pusher bar, extended from the cutoff roll along with the knife, impales the web onto the pins. Transfer pads carried by the bed roll extend, to detach the web from the pins and clamp it against a new core. Cores onto which web is wound are supported by six mandrels spaced circumferentially around a turret that carries them, in turn, to each of six fixed stations. Coaxial with each mandrel on the turret is a rotatable driver and a normally disengaged clutch which, when engaged, transmits rotation of its driver to its mandrel. Alternate drivers around the turret are driven from one motor, the remaining drivers by a second motor.

Abstract: This apparatus utilizes a traveling looped conveyor belt upon which a plurality of previously slit web ribbons are received. The conveyor belt is then movably positioned to partially wrap a spool to simultaneously urge each of the ribbons into wrapping engagement with the rotating spool to be wound into a roll thereon. The traveling conveyor belt is selectively positionable about the spool and drive drum to permit removal of the wound roll and the positioning of a new spool so that transfer of the plurality of ribbons can be made from the wound roll to the next spool quickly and automatically at normal operating machine speed.
Abstract: The roller winding machine for the formation of individual reels from longitudinally cut material bands comprises a sickle-shaped supporting and cutting table which is capable of being pivoted between a carrying roll and the material band if the material band is to be cut crosswise. The cutting of the material band is carried out in a precisely defined position upon the supporting and cutting table. One or more adhesive-label issue devices also cooperate with the supporting and cutting table. By means of the adhesive labels, the beginning of the band is fastened to the empty reel sleeve, and the band end is fastened to the full reel, respectively.
Abstract: Disclosed is a sheet splicer for splicing sheets of paper, sheet or film, especially for splicing paper rolls together to form a continuous web joining the old and new rolls of paper when used in continuous web printing presses so that they can be spliced together by a butt end splice. A traverse blade cuts both the old and new plies along a butt edge line. The blade is followed by a tape applicator and paper stripper which strips the selvage and then joins the plies together as a butt edge seam of the old and new sheets. The splicer is designed as a stand alone unit or as an in-place attachment for a printing press.
Abstract: A perforating machine for making tear lines in a woven or non-woven fiber sheet material. The machine comprises a feeder mechanism for feeding a web of sheet material. A roller assembly maintains the web stretched while a further roller imposes tension to the web along the longitudinal axis thereof. A perforating roll assembly is provided to cut fibers in the web along a line whereby to form a tear line substantially transverse to the direction of tension while maintaining the tension in the web. Traction rolls positively engage the web through the perforating roll assembly. An accumulator roll assembly receives the web after the tear lines have been made therein.
Abstract: There is described a device for longitudinally slitting a web and for separating the separated portions thereof before they are fed onto a takeup reel or core.
Abstract: A cable safety apparatus for use in a cable feeding system, comprising a pulley rotatably mounted on a frame, the pulley supporting the cable in a manner to provide a back pressure thereon. A locking member is slidably connected to the frame with a spring interposed therebetween, and the apparatus is suspended to a non-moving support structure by attaching the support end of the locking member to an external structure. The locking member and spring form a spring assembly that has locking engagement with a pivotable cutter blade that is biased to be in cutting engagement with the cable when the spring assembly is moved into clearing relationship with the cutter blade.
