Patent number: 5167177Abstract: An apparatus for slicing objects, such as potatoes, with a rotatably mounted knife assembly. Objects (such as potatoes) to be sliced are conveyed downward toward the knife assembly between a gripper chain and a feed chain. A pair of springs provide a biasing force which urges the chains together, thereby ensuring that the conveyed potatoes are fed positively and uniformly toward the knife assembly. Preferably, two feed rolls having teeth are mounted between the lower ends of the chains and the knife assembly (each feed roll at the end of a rotating, slidable shaft). The teeth of the rotating feed rolls grip each potato conveyed against them by the chains, and force each such potato downward against the rotating knife assembly. Preferably, a support and retaining plate is fixedly mounted to the feed mechanism to constrain vertical movement of the feed rolls as they rotate with a potato gripped between them.Type: GrantFiled: October 18, 1991Date of Patent: December 1, 1992Assignee: Ashlock Company, Division of Vistan CorporationInventors: Fredrick J.

Patent number: 5079982Abstract: A slicing machine includes a rotatable blade (1) and a feeding device (4, 5) for feeding blocks of product (46) towards the blade (1). The feeding device comprises opposed driven endless track assemblies (4, 5) having their adjacent faces arranged to be driven in the same direction. One of the opposed track assemblies (4) is formed by a number of separate side-by-side endless tracks (6, 7, 8, 9) which are pivotally connected to a common support (20). The number of separate tracks (6, 7, 8, 9) have a ganged drive and pneumatic rams (22) which, in use, urge the downstream ends of the tracks independently towards the block of product (46) so that the separate tracks pivot independently and hold a block of product (46) the thickness of which is not uniform in the transverse direction. The support (20) supports the upstream ends of the endless tracks (6, 7, 8, 9) and is slideably mounted for movement in a direction parallel to the plane of the blade (1).Type: GrantFiled: July 11, 1990Date of Patent: January 14, 1992Assignee: Thurne Engineering Co., Ltd.Inventor: Peter Antonissen

Patent number: 5078032Abstract: A device for cutting wire which includes at least one rotating knife supported on a rotating knife carrier and a counter-tool. The counter-tool includes a cutting blade rotating about a vertical first axis and having a central opening therethrough and adapted to receive the wire to be cut therethrough. The knife carrier is rotatingly supported about a second axis which is parallel with respect to the first axis, and the knife is guided along the cutting blade past the central opening to cut the wire thereat.Type: GrantFiled: September 7, 1990Date of Patent: January 7, 1992Assignee: Berkenhoff GmbHInventor: Hans-Juergen Gerlach

Patent number: 5072637Abstract: An apparatus and method for cutting continuous webs having varying thicknesses, widths, and compositions into sheets. The apparatus includes a pair of oppositely rotating web feed assemblies employing a unique floating nip and clamping mechanism which engages the web and advances it a specified length past a poised cutting blade assembly and onto a simultaneously driven exit assembly. After the desired length of web has been fed, the drive mechanisms stop, and the cutting blade assembly cycles to clamp the web on the upstream side and cut. During the cutting stroke the web is held taut on the downstream side by the web feed assemblies. Upon completion of the clamping and cutting stroke, the cutting blade assembly returns and stops at its poised position.Type: GrantFiled: April 30, 1990Date of Patent: December 17, 1991Assignee: Sealed Air CorporationInventors: Abraham N. Reichental, Alex Shafir

Patent number: 5062340Abstract: Apparatus for cutting a continuous web into precise length sheets and precisely stacking the sheets, relative to each other, includes first and second moving endless belt tables for advancing the web, a sheet orientation table and a stacking table. A vacuum holds the web firmly, without tension, against the respective belts. A shearing device is disposed between the first and second endless belts. Web, detectors positioned along the line of travel of the web, detect printed or colored lines on the web to obtain accurately cut sheets. Individually driven and positioned sheet grippers grasp the cut sheet positioning each sheet under dual hole punching devices which punch precisely positioned holes in each sheet. A pair of aligning pins on a sheet stacking bed are used as guides for orienting the sheets in interleave configuration. Each sheet is secured to its adjacent sheet to maintain sheet orientation.Type: GrantFiled: June 21, 1990Date of Patent: November 5, 1991Inventor: Richard Greven

Patent number: 5042347Abstract: An apparatus for guiding a traveling web of textile material is provided for guiding a web traveling in an apparatus for trimming selvedge from the web. The web guiding apparatus includes a device for supporting the traveling web during the feed of the web from a web conveying assembly to a severing location at which a selvedge is severed from the web. The support device includes an endless belt assembly having an endless belt traveling in an inclined direction with respect to the web travel path of the web conveying assembly. The web guiding apparatus further includes a support bar for supporting the web laterally inwardly of the endless belt.Type: GrantFiled: October 11, 1989Date of Patent: August 27, 1991Assignee: A. Monforts GmbH & Co.Inventors: Gottfried Baum, Manfred Rontgen

Patent number: 5040442Abstract: A laminate cutting apparatus includes a cutter head moved horizontally back and forth above a support member which supports a laminate, and a cutting member and piercing blade mounted on the cutter head, with the cutting member comprising a knife-shaped cutting blade or the cutting blade and a cutting blade guide. The upper surface of a cutter rest moved in synchronization with the cutter head and in the same direction is arranged flush with a supporting surface of the support member. There are provided a cutting member receiving body into which receives the cutting member, and a piercing blade receiving body which receives the piercing blade. The cutting member and the piercing blade are adapted so as to turn in the same direction and so as to be raised and lowered independently of each other. Furthermore, the cutting member receiving member is adapted so as to turn in synchronization with the cutting member and in the same direction.Type: GrantFiled: August 24, 1990Date of Patent: August 20, 1991Assignee: Kabushiki Kaisha Kawakami SeisakushoInventor: Nobuo Nasu
