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: 5181669Abstract: A cassette loader for loading a length of magnetic tape into cassette having a relatively short length of leader tape pre-loaded into the cassette and attached by opposite ends to respective first and second cassette hubs. The cassette loader includes a leader equalization position for holding a cassette; a leader equalizer for winding the leader tape substantially completely onto one or the other of the first and second cassette hubs while the cassette is in the leader equalization position and a cassette loading position spaced-apart from the leader equalization position for loading a length of magnetic tape into a cassette which has previously been processed in the leader equalization position. A cassette loading position is provided for loading a length of magnetic tape into the cassette at the cassette loading position simultaneously with the operation of the leader equalizer on the cassette in the leader equalization position.Type: GrantFiled: November 6, 1990Date of Patent: January 26, 1993Assignee: Concept DesignInventors: Drey Johnson, Robert Gaude, Robert I.

Patent number: 5171396Abstract: A device for splicing paper webs for the manufacture of corrugated board. At least one pressing and redirecting roller is provided to receive the terminating web to be spliced from a web roll. Two clamping rollers, which function in an alternating manner, grasp the terminating web from the web roll. The clasping rollers are moveable from their initial positions to operating positions. A clamping beam, which functions in an alternating manner with one or the other clasping rollers, includes pressing faces disposed oppositely facing each other, there being one beam for each of the clasping rollers. Each clamping beam has a pressing face for pressing the web which runs across it. Two breaking beams alternatingly cooperate with the upper side of the clamping beam for one or the other clasping roller to bring the terminating web to rest. Two alternatingly functioning knives act to cut off the web which is played out.Type: GrantFiled: April 22, 1991Date of Patent: December 15, 1992Assignee: BHS-Bayerische Berg-, Hutten- und Salzwerke AktiengesellschaftInventors: Armin Rank, Alfons Gnan

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. To remove a superfluous portion of the tape from the continuous loop, the loop is moved to a position wherein one end of the superfluous length is located over the cutting/connecting section. The tape is clamped and cut. One of the two tape clamps then lifts the now open end of the loop clear and the superfluous portion is spliced to the tape on a supply reel. The reel is rotated in manner which winds the superfluous length thereonto until the other end of the superfluous length is drawn to the cutting/connecting section.Type: GrantFiled: March 29, 1991Date of Patent: December 8, 1992Assignee: Sony Magnescale, Inc.Inventors: Masayoshi Matsuyama, Yoshihiko Miyasaka, Yoshiki Takao

Patent number: 5164031Abstract: A cutting/connection device of a tape splicer includes a fixed base member and a vertically displaceable member. The end portions of tapes to be spliced are overlaid one on top of the other on the device. A cutter severes the tapes so that the movable member can be vertically displaced in a manner which brings the free ends of the two tapes to the same level. Under these conditions a strip of adhesive tape is applied to splice the tapes together.Type: GrantFiled: April 1, 1991Date of Patent: November 17, 1992Assignee: Sony Magnescale, Inc.Inventors: Masayoshi Matsuyama, Yoichi Kawaharasaki
