Patent number: 7293592Abstract: Self-adhesive labels are formed by repetitively cutting linerless web material which is fed from a roll into and through a rotary knife cutter. The labels are then transported to and applied to articles. To improve cutting of the web and labeling, the web and or labels are contoured, e.g., they are made concave, in a plane transverse to the direction of flow path. To contour the web or labels, alternative endless belt arrangements are used, wherein the center line of the adhesive side of the web is adhered to a belt surface. Preferably, a one-piece belt having spaced apart and movable lengthwise portions is used. Different transport velocities are used for web fed to the cutter and for labels taken-away from the cutter. Cutter motion, and thus label length, in forming either linerless and lined labels, is controlled according to how printed indicia bar marks on the web are severed into portions; alternatively, according to whether or not the cut falls between two spaced apart printed indicia.Type: GrantFiled: March 3, 2004Date of Patent: November 13, 2007Assignee: George Schmitt & Co., IncInventors: Roman M.

Patent number: 6533104Abstract: A device for receiving and transporting objects has at least one pair of parallel chains or belts situated opposite each other and driven in synchrony, which define a space between each other for transporting the objects therethrough. Each chain has at least one gripper which is mounted so as to be pivotable thereon and faces a corresponding gripper on the other chain. Each gripper has an extension which is moveable along a guiding path. The guiding path has a path section sloped with respect to the direction of transport of the objects at the point of receipt of the objects, so that, when the chain is moving, the extension of the gripper is deflected along the sloped path section and thus a rotational movement countering the translational movement caused by the chain is imparted to the gripper. Thus no rotational movement occurs at the moment of contact between the gripper and the object.Type: GrantFiled: April 4, 2001Date of Patent: March 18, 2003Assignee: Starlinger & Co.

Patent number: 4815581Abstract: An apparatus for separating articles advanced in series and in a mutually contacting relationship, includes a first conveyor advancing the articles in a series and in contact with one another on a first conveyor surface, and a second conveyor arranged for receiving articles from the first conveyor and advancing the articles in series on a second conveyor surface. The second conveyor has a conveying speed greater than that of the first conveyor, whereby the articles are advanced on the second conveyor surface in a spaced relationship to one another. There is further provided a third conveyor having article carriers which convey the articles downstream of the second conveyor surface as viewed in a direction of article advance. A suction device generates, in zones of the first and second conveyors, a force exerted on the articles and oriented for pressing the articles against the first and second conveyor surfaces.Type: GrantFiled: June 25, 1986Date of Patent: March 28, 1989Assignee: SIG Schweizerische Industrie-GesellschaftInventor: Gert Deutschlander

Patent number: 4770284Abstract: Apparatus for transporting folded sheets has one or two pairs of chain conveyors whose horizontal upper reaches define two spaced-apart portions of a first path for the transport of successive folded sheets of a series of sheets in such a way that the sheets ride on the pairs of conveyors in inverted positions (with the backs on top). An additional chain conveyor has a horizontal upper run defining a second horizontal path between the first and second portions of the first path to transfer the sheets from the first to the second portion of the first pair. The additional chain conveyor advances successive sheets along a stationary ramp which pivots the panels of the sheets apart so that the thus exposed inner sides of the panels are accessible for the application of printed information, labels or the like. The speed of the additional conveyor can slightly exceed the speed of the other chain conveyor or conveyors.Type: GrantFiled: February 25, 1986Date of Patent: September 13, 1988Assignee: Grapha-Holding AGInventor: Heinz Boss

Patent number: 4751060Abstract: The present invention is an improved extractor (10) for removing a liquid from a solid carrier medium in which the liquid is entrained. The extraction process is accomplished by utilizing both percolation and immersion removal methods. The extractor (10) includes a plurality of pools (12, 12') through which the solid entraining the liquid therein is moved in a direction counter-flow to that in which a solvent passes through the extractor (10). Percolation removal is effected at the overflow (48, 48') of each pool (12, 12') as solvent washes through the solids being processed. Immersion is effected at the lower end of a sloped floor (22, 22') of each pool (12, 12') where the solids are soaked in the solvent. A final percolation bath (14) can be provided as a last stage of the extractor (10).Type: GrantFiled: May 6, 1985Date of Patent: June 14, 1988Assignee: Crown Iron Works CompanyInventor: William L.

Patent number: 4733770Abstract: A transfer station is disclosed for transferring mineral material from a longwall conveyor to a loading conveyor. The loading conveyor has two straight portions joined by a curved portion, one of the straight portions extending in the longitudinal direction of the longwall conveyor, and being positioned beneath the end of the longwall conveyor. The longwall conveyor extends over the loading conveyor in the region of its curved portion. Larger pieces of mineral material are deflected, by a lateral deflector in the exit region of the curved portion of the loading conveyor, from the longwall conveyor, while the finer conveyed material is delivered at the end of the longwall conveyor onto the loading conveyor.Type: GrantFiled: July 2, 1987Date of Patent: March 29, 1988Assignee: Gewerkschaft Eisenhutte Westfalia GmbHInventor: Ulrich Temme

Patent number: 4673079Abstract: A transfer station assembly is provided for transferring mineral material from a longwall scraper-chain conveyor to a roadway scraper-chain conveyor. The transfer station includes a box frame, in which the upper run of the roadway conveyor is guided between the upper and lower runs of the longwall conveyor. Guide bars are provided for guiding the scrapers of the scraper assembly of the roadway conveyor within the box frame. The guide bars for the roadway conveyor are detachably secured to the box frame so as to be readily releasable and replaceable by other guide bars, whereby roadway conveyors of different types and/or widths can be connected to the box frame.Type: GrantFiled: February 28, 1985Date of Patent: June 16, 1987Assignee: Gewerkschaft Eisenhutte Westfalia GmbHInventors: Dieter Grundken, Reinhold Bruggemann

Patent number: 4648504Abstract: A conveyor device has two endless conveyor belts extending in alignment and advancing in the same direction of (X--X), the adjacent ends of the belts being oriented diagonally with respect to the direction. During transfer between the two belts the products gradually abandon the first belt and pass gradually onto the second belt. This avoids any stumbling of the products, even when these are of narrow and elongate form.Type: GrantFiled: July 9, 1984Date of Patent: March 10, 1987Assignee: Cavanna S.p.A.Inventor: Renzo Francioni

Patent number: 4543143Abstract: A process and apparatus for the covering of playing balls, in particular tennis balls, utilize two essentially dumbbell-shaped cover parts and apply the parts interlockingly at an angle of 90.degree., successively to the adhesive coated ball core by rolling over the laid out, dumbbell-shaped cover parts. The cover parts are stacked to form a magazine and are provided with a layer of an adhesive so that only their peripheral surfaces are coated. The adhesive coated ball cores are rolled successively, initially by means of a contact pressure device in the longitudinal direction over a first cover part magazine and subsequently by means of a second contact pressure device and second cover part magazine extending transversely to the longitudinal direction of the first cover part magazine. The edge of the second cover part engages the bight of the cover part already in position at a decorative seam gap.Type: GrantFiled: October 29, 1984Date of Patent: September 24, 1985Assignee: Dietmar SiebertzInventors: Dietmar Siebertz, Stephan Siebertz
