Patent number: 5190234Abstract: In a web handling apparatus for continuously supplying a running web to a web-consuming machine using a main accumulator to provide uninterrupted feed of the web during splicing of the trailing end of an expiring roll to the leading end of a ready roll, an improved ready-roll acceleration technique uses a supplemental accumulator disposed between the ready roll and the splicing head to enable the ready roll to be accelerated prior to completion of the splice. This technique permits the use of a smaller main accumulator and/or increased running speeds. In fact, the total storage capacity of the main and supplemental accumulators can be less than that of the single accumulator of conventional apparatus of this type. Furthermore, the running roll can be slowed without adverse consequence so as to reduce web tension upsets. The invention is also useful in web winder/splicer applications.Type: GrantFiled: January 27, 1992Date of Patent: March 2, 1993Assignee: Butler Automatic, Inc.Inventor: Frederick D. Ezekiel

Patent number: 5169466Abstract: A length of tape is drawn off a reel, passed over the cutting/connecting section of a splicer, passed through a temporary storage vessel and looped back so as to pass over the cutting/connecting section again. Tape clamps hold the two layers of tape on the cutting/connecting section which are then cut. One of the tape clamps is withdrawn while an applicator applies a piece of adhesive tape in a manner which splices a continuous loop of tape.

Patent number: 5163594Abstract: In one embodiment of a web accumulator, at least one pneumatic cylinder actuator has a chain loop connected to opposite ends of its piston rod. Translation of the chain in response to pressurizing the cylinder causes the chain to drive two spaced apart axle shafts in the same rotational direction. An arm is fastened to each axle shaft and there is a row of rollers on each arm and a roller on each axle shaft. Web is threaded in loops back and forth between rollers on the respective arms. When the web infeed rate to the accumulator and the outfeed or rate at which the web is drawn out by a web consuming device are equal, the regulated air pressure to the actuator drives the arms apart to thereby accumulate a long length of web. When web infeed is interrupted while outfeed or draw persists, the arms are pulled toward each other and they pay out the stored length of web.Type: GrantFiled: February 10, 1992Date of Patent: November 17, 1992Assignee: Curt G.

Patent number: 5066347Abstract: The present invention relates to a tape transport apparatus and a tape introduction method for forming a magnetic tape into an endless loop by splicing a leader tape to the magnetic tape and running such endless-loop magnetic tape therein. When an endless loop is shaped by splicing the magnetic tape and the leader tape to each other, the starting (front) end of the magnetic tape is drawn out to a splicing position while the front (fore) end of the leader tape is also brought thereto and, after the respective ends are spliced together, the endless loop is moved until the spliced portion between the magnetic tape and the leader tape is shifted to the splicing position for the leader tape. The starting front end of the magnetic tape led by such leader tape is then spliced to the terminal rear end of the magnetic tape, so that an endless loop is formed automatically without the necessity of the performance of operation by hand upon the magnetic tape.Type: GrantFiled: July 11, 1988Date of Patent: November 19, 1991Assignee: Otari Electric Co.

Patent number: 5050812Abstract: An envelope machine which makes two envelopes at once. One web is used up to a relatively advanced point in the envelope forming process to simultaneously form two envelopes. At a terminal portion of the envelope processing, the web is cut lengthwise to form two envelopes. The device also includes improved structure for maintaining uniform the tension on the web. This need for uniform tension is made more prevalent by the thickness of the web which must be used to form two envelopes in parallel. The structure of the present invention which maintains uniform the thickness of the web is formed herein by a dancer roll which moves in a longitudinal fashion in cooperation with movement of other associated rolls. Whenever the dancer roll reaches one of its stopping points, it sets off a limit switch which operates a piston to change the type of moving being applied to the dancer rolls.Type: GrantFiled: December 5, 1990Date of Patent: September 24, 1991Assignee: Sterling Envelope CorporationInventor: Henry H. J. Mueller

Patent number: 5039374Abstract: A splicing device for label webs mechanically holds the leading end of the new web and is rapidly transferred to splicing position and accelerated into the running speed of the web while the rotational speed of the web supply spool that is associated with the leading end of the replacement web is initially gradually adjusted to the running speed of the label web. The leading end of the replacement web and the trailing end of the expiring web are glued in an overlapping manner. The splicing device has two identically constructed multi-functional drums which are arranged to function alternately and are equipped with a gripper, cutter, free running deflector roller and pressure application device.Type: GrantFiled: July 10, 1990Date of Patent: August 13, 1991Assignee: Krones AG Hermann Kronseder MaschinenfabrikInventor: Horst Winter

Patent number: 4984750Abstract: A method an apparatus for replacing reels of web-like material having a paper-end gripping arm having an attraction surface and a keep pawl. A peeling member peels of a bonded end portion of the material and the material is delivered along a transport path where it is held and the bonded end portion is cut off. The cut end portion is then removed from the transport path. Two reels are supported on reel holding portions and are alternately fed to the transport path. The end portion is bonded to the reel by boring a hole in the end portion, attaching tape to the outer surface in the area of the hole and pressing the tape inwardly so that it extends through the hole and is bonded to the outer surface of the material beneath the hole.Type: GrantFiled: June 30, 1989Date of Patent: January 15, 1991Assignee: Tokyo Automatic Machinery Works Ltd.Inventors: Toshio Shigeta, Yoshio Kishi, Toshihide Kohata, Makoto Sakano
