Abstract: The invention provides a method and apparatus for folding lengthwise and clamping a flexible binding, while leaving the edges of the clamped binding free to be separated such that the edge of a length of extensible netting may be inserted between the free edges. A progressive linear clamp is provided for progressively clamping the combined netting and binding material as the netting is inserted to thereby permit an operator to obtain a substantially uniform stretch of the edge of the netting material, and to apportion the netting evenly along the binding. With the netting material thus inserted and clamped between the edges of the binding, a feed mechanism is positioned to engage the combined binding and netting and feed it to a sewing machine to permanently secure the materials together.

Abstract: An improved lithographic dampener of the type having continuous plate/form roller/metering roller contact, adaptable to a variety of press configurations and operating speeds, employs a friction-driven oscillator roller that distributes added dampening liquid and the ink/liquid emulsions on the metering roller, to avoid continuing patterns which might cause ghosting in printed images. The dampener has a simple drawer-like configuration, with an open front for improved range of form roller/plate contact. A pan with a remote supply of dampening liquid, is located under the rollers such that the metering roller surface contacts and picks up liquid from a pool in the pan. Simplified seal dams at the ends of the form/metering rollers' nip keep the reservoir of liquid in that nip, yet minimize wear of the seal configuration. A slide block mounting of the metering roller and oscillator rollers allows independent adjustment of pressure at the form/metering rollers' nip, and at the metering/oscillator rollers' nip.

Abstract: A ply server for applying a preselected length of ply material drawn from a supply roll thereof onto a tire carcass building drum. The desired length of ply material is measured by a programmable mechanism, then severed at the length desired. The incoming ply material is center guided onto the ply conveyor, or (optionally) a transverse scanner device is used to determine the location of the longitudinal centerline of the length of ply material. The carcass building drum is precisely located with respect to the longitudinal centerline of the ply material. At the opposite end of the server, there is a receptor arrangement into which a cart bearing the supply roll can be brought to the server and the ply material fed into the server, with the separator for the rolled uncured ply material being rewound as part of the material pay-out process.

Abstract: A programmable sewing head including a work controlling clamping mechanism is automatically loaded with air bag material or the like, together with a reinforcement strategically placed thereon, for automatic attachment (by a predetermined stitching pattern) of the reinforcement to the bag material. A table having a loading station supports material orienting an aperture and the reinforcement, and extends to a transfer station at the sewing head. A locator aperture and a retractable locator head are in the table surface at the loading station for receiving the sheet and reinforcement. Placement of the reinforcement and the sheet over the locator pad aligns the reinforcement with respect to the hole in the sheet.

Abstract: An air bladder is formed by producing a foil imprint on an inner surface of a first uncured rubber sheet, by heat pressing the imprint from a hot roll leaf stamping tape to the sheet. The first sheet is delivered from a reel to the heat press via a driven roller and idler roller combination. The hot roll leaf stamping tape is delivered above the first sheet via a take up reel and idler roller combination. The heating press includes a heated platen having the contour of the desired imprint, such that the imprint takes on the shape of the heated platen. A second sheet of uncured rubber is laminated to the first sheet, with the second sheet laminated over the first sheet, thereby convering the imprint. The two sheets are vulcanized which cures the non-imprinted surfaces of the rubber sheets together, thereby forming an air pocket in the shape of the imprint between the two sheets.

Abstract: An improved integral rivet button and resulting rivet, and a process and tooling for forming such button, utilizes successive coining steps on material surrounding the base of an initial bubble formed on a can end, causing flow of material along the wall of the button toward its center. The successive coining at progressively lesser radii affords adequate metal in the bubble region to assure ultimate formation of an accurate button, assures a strong boundary region about the base of the button, and assures the rivet head is sufficiently large to prevent tear out of the tab at its juncture with the rivet. The initial coined boundary is located close to the juncture of the initial bubble wall with the remainder of the shell, where curvature of the initial bubble wall is concave in the direction of the bubble top and toward the ultimate public side of the end.
