Title: Apparatus for attaching pressure-sensitive adhesive sheet material to a label
IPC: B65C9/20
Filed: 1967-09-26
Abstract: 1,194,038. Attaching adhesive strip material to labels. MINNESOTA MINING & MFG. CO. 26 Sept., 1967 [27 Sept., 1966], No. 43840/67. Heading B5N. A machine comprises means for mounting a supply of pressure-sensitive adhesive sheet material having a liner adhered to one side thereof, means for supporting a label while the exposed adhesive side of the sheet material is adhered thereto, and means for stripping the liner from the sheet material adhered to the label. As shown, adhesive tape with a release liner adhered to one side is drawn from a roll 46 and passes via a roll 44 to a roller 22, the exposed adhesive side of the tape being uppermost. Between roller 22 and a gravity-biased gate 58, the tape contacts and adheres to the bottom label of a stack S of labels, the motion of the tape drawing this label from right to left between roller 22 and gate 58 whilst a strip of adhesive tape is secured right across the back of the label. The label slides on two spaced parallel rails 20, between which a roller 28 is located. The release liner L follows the contour of this roller 28 and leaves the adhesive tape secured to the label. On leaving roller 28, the separated liner is drawn, via a roll 80, between two meshing toothed wheels 70 and 76, the former being driven by an electric motor 66. When the label, to which the tape has been applied, clears roller 22, a second label contacts the adhesive tape and is moved along rails 20, behind and abutting the first label. On further movement, the first label throws a lever 86 to operate a switch 84, which in turn stops the driving motor 66 and causes a solenoid 88 to urge a holding pad 90 against the second label. The first label can now be removed from the machine and the tape between it and the firmly-held second label torn. On removing the first label, the lever 86 springs back to restart the machine. The label stack S is held substantially clear of rails 20 by an adjustable wedge 64 to reduce friction between the bottom label and the rails. A second gravity biased member 62 bears on the top of the stack. The lateral position of the stack with respect to the tape can be adjusted by adjustable stackguiding plates 56. The rollers 22 and 28 are mounted in a frame 24, which is pivotably mounted at 26 to a stationary part of the machine. The frame may be pivoted from its operative position to the dotted-line position shown to facilitate initial threading of the tape through the machine.

Abstract: 1,003,520. Discharge tubes. STANDARD TELEPHONES & CABLES Ltd. Dec. 8, 1961 [Dec. 14, 1960], No. 44051/61. Heading H1D. [Also in Division B3] In an electron discharge device, a grid electrode comprises an outer metal frame 1 and cells formed by metal struts 3 disposed in honeycomb arrangement within the frame, the arrangement including an outermost ring of cells each having one wall formed by the frame 1 and at least one inner ring of hexagonal cells inside the outermost ring of cells and contiguous therewith, wherein the metal struts forming the cell walls are thicker in an outer ring of cells than in an inner ring. In a preferred manner of manufacture, a bundle of six copper-coated aluminium wires arranged regularly around a similar central wire is dipped in molten tin to attach the wires together. Next, twelve aluminium wires with thicker copper coatings are laid about the first bundle and the tin dipping process repeated. The process may be repeated with further outer layers of 18, 24 ... wires. The coatings preferably increase in thickness in even graduation, e.g. in integral multiples. The complete tinbonded bundle of wires is now inserted into a copper sleeve 1, preferably having a hexagonal internal periphery, and the whole drawn down to reduce the diameter by 25%, after which the assembly is inserted into an iron tube and the whole drawn down again. After slicing into discs and hand lapping to the correct thickness, the aluminium cores are etched out and the grid is subjected to a sintering process so that the former copper coatings form interconnected metal struts. Instead of using a central wire of coppercoated aluminium to form a grid with a central hexagonal cell, a thinner central wire of steel may be used, which wire is removed after the drawing-down process, the central copper tubing also being etched out, to form a grid with a central aperture 7, as shown, to reduce electroninterception.
