Patent number: 5769301Abstract: A media transport bridge is an integral media transport device within an internal drum laser imagesetter that transports media from an imaging area in the drum to an external processor or intermediate buffer. Five pairs of rollers transport the film over the drum. A first stage of the bridge includes a first pair of rollers driven independently so that the first stage is removable and replaceable with a take-up cassette if desired. A friction drive within the imagesetter is adaptable to drive either the first stage or the take-up cassette when installed. Upon removal of the first stage, an automatic adjustment of the bridge is performed to balance the pivotally mounted bridge. The media is moved into the bridge by a pair of drum rollers while the first stage is synchronized with the other four pairs of rollers in the bridge and monitored to keep a slack loop of media at the first stage rollers to eliminate perturbations in the media.Type: GrantFiled: October 23, 1996Date of Patent: June 23, 1998Assignee: Agfa Division, Bayer CorporationInventors: Thomas K. Hebert, Mark E. Tellam, Libor Krupica, Peter Austin, Edward L. Kelley

Patent number: 5704304Abstract: An apparatus and method are provided for simultaneously feeding two or more rolls of material into a sewing and cutting system. Specifically, the apparatus includes a roll let-off for supporting and feeding a first roll of material or cloth. The let-off includes a tension control unit for feeding the cloth at constant tension. A second roll let-off is also included for supporting and feeding a second roll of material. The second roll let-off also includes a tension control unit in combination with a torque supplying device. The tension control unit and the torque supplying device are adjusted to place a single tension on the material that allows the second roll of material to be fed with the first roll of material simultaneously and uniformly. By using the apparatus of the present invention, improved sewn products can be produced automatically.Type: GrantFiled: January 13, 1995Date of Patent: January 6, 1998Assignee: Burton & NoonanInventors: Perry E. Burton, John V. Noonan

Patent number: 5586708Abstract: A packaging machine that has features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which frictionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism.Type: GrantFiled: June 8, 1995Date of Patent: December 24, 1996Assignee: Automated Packaging Systems, Inc.Inventors: Bernard Lerner, Richard W. Hess, William M. Cronauer, Rick S. Wehrmann, James D. Kramer

Patent number: 5540371Abstract: A method of adjusting a wire feeder having a pusher system (12) and a puller system (14) to avoid birdnesting and collapse of the wire (11) in the wire guide or conduit (13) when the tip (15) of the wire feeder is blocked or a wire jam occurs. The pusher system (12) is adjusted by activating both the pusher system (12) and the puller system (14), adjusting the pusher system (12) to provide a desired wire feed speed when the tip (15) is not blocked, blocking the tip (15), and adjusting the pressure exerted by the rollers (22) of the pusher system (12) so that these rollers (22) slip on the wire (11) when the tip (15) is blocked. The puller system (14) is adjusted by disabling the pusher system (12), blocking the tip (15), activating the puller system (14), and adjusting the pressure exerted by the rollers (32) of the puller system (14) so that these rollers (32) do not slip on the wire (11).Type: GrantFiled: September 26, 1994Date of Patent: July 30, 1996Inventor: Malcolm T.

Patent number: 5524805Abstract: A web feed roller is driven by a compact and simple web feed roller drive device included in the web feed roller. The web feed roller comprises a support shaft, a cylindrical hollow member rotatably supported on the support shaft, a stator provided with an electrically conductive member and fixed on the support shaft, a rotor fixed on the cylindrical hollow member to face with the stator, and an electrical connecting member connected to the conductive member of the stator. The web feed roller is electrically connected to a drive control system comprising a speed control device to control driving speed of the web feed roller, and a signal generating device for outputting a speed signal representing an actual speed of the web feed roller into the speed control device.Type: GrantFiled: December 28, 1992Date of Patent: June 11, 1996Assignee: Kabushikigaisha Tokyo Kikai SeisakushoInventors: Noriyuki Shiba, Masayoshi Sato

Patent number: 5511712Abstract: Damage to rotating cylinders in a web-fed rotary printing machine, due to breaks or tears in the material web passing through the machine, is prevented by providing a web guide roller with a directionally switched coupling intermediate two spaced gripping locations. If the web breaks, the web guide roller becomes positively driven and prevents web roll up on one of the rotating cylinders.Type: GrantFiled: November 23, 1994Date of Patent: April 30, 1996Assignee: Koenig & Bauer AktiengesellschaftInventors: Helmut Holm, Volker G.

Patent number: 5497928Abstract: Wire is fed along a predetermined path by virtue of being pinched between an upper set of feed rolls and a lower set of feed rolls while the upper and lower rolls are rotated in opposite directions. The upper feed rolls are journaled cantilever fashion by an upper carrier which is fixed to the main frame of the apparatus. The lower feed rolls are similarly journaled by a lower carrier which is adapted to be moved upwardly toward the upper carrier to cause the lower feed rolls to pinch the wire against upper feed rolls after the wire has been threaded between the rolls. The lower carrier is moved upwardly by actuators which are offset laterally from the cantilevered rolls.Type: GrantFiled: May 12, 1994Date of Patent: March 12, 1996Assignee: Rockford Manufacturing Group, Inc.Inventors: Irvin Burns, Patrick Robbins

Patent number: 5475907Abstract: An apparatus and method are provided for forming coils of yarn and for heat setting the yarn. The apparatus has a coiler adapted to receive yarn from a yarn source ant to form the yarn into a plurality of loops of a desired size. The coiler preferably includes a supporting frame, a pair of feed rolls mounted on the supporting frame and adapted for feeding yarn from the yarn source, and a rotatable coiler tube positioned downstream from the feed rolls. An air blowing device is positioned between the feed rolls and the coiler tube for facilitating the advance of the yarn into and through the coiler tube. A first variable speed drive is connected to the pair of feed rolls and a second variable speed drive is connected to the coiler tube for rotating the coiler tube at a selected speed to thereby form loops of yarn of a desired size.Type: GrantFiled: May 4, 1995Date of Patent: December 19, 1995Assignee: American Line CorporationInventor: Donald L.

Patent number: 5419480Abstract: A feed arrangement for a rotating bar includes a rotary drive carrying a series of axially spaced clamping devices comprising collets through which the bar passes. The clamping devices are axially reciprocated in phased sequence and the collet of each device closes upon the bar while the device is moving forwards. The sequence is so controlled that at all times the bar is clamped by the collet of at least one forwardly moving device and is thereby continuously fed forwards while being rotated by the active clamping device.Type: GrantFiled: April 30, 1993Date of Patent: May 30, 1995Assignee: Rolls-Royce plcInventor: Arnold J.
