Abstract: 928,135. Apparatus for making cartons. METAL BOX CO. Ltd. May 26, 1961 [July 1, 1960], No. 23173/60. Class 18. A carton blank is set-up into a four-sided body portion, the sides 2, 3, 4, 5, of which are retained upright by corner flaps 6 hingedly connected to sides 2, 3 of the body and which overlie and are stuck to other such sides 4, 5 by means of apparatus comprising a four-sided die, a forming punch movable through the die with a continuous movement to set-up the blank as in Fig. 2, and rollers 31 associated with the die which apply pressure to overlying flaps 6 and wall portions 4, 5 to cause them to adhere to each other by reason of previously applied adhesive material. The punch may be continuously reciprocable or there may be a plurality of punches on a conveyer moving in succession through the die, horizontally or vertically. The carton is of the kind shown in which flap 9 tucks between wall 2 and the edges 10 of flaps 11 when the carton is closed. In one embodiment, the inner surface of the blank is coated with polyethylene, and in another the opposite sides of the blank are waxed while the adhesion areas are coated with a thermo-plastic adhesive such as a polyvinyl acetate resin which melts at about 20C., above the wax melting point. The thermoplastic adhesive is pre-softened by heating or the die may have heater elements and the blank B is fed to overlie the die and is positioned by guides 12, 13; the punch then moves downwardly to engage the bottom 1 of the blank and drive it into the die where the overlying corner flaps, 6 engage flap guides 40 and are folded inwardly. Rolling pressure is applied by rollers 31 mounted on spindles 29, 30 in resilient housings 23, 24 and protruding into the openings 32, 33 between walls 19, 21 and 20, 22 respectively, this protrusion being controlled by screws 34. The punch continues downwardly and pushes the set-up carton out of the bottom of the die where stripper elements remove it. If the carton lid 8 has side flaps, these are folded against portions 39 of the punch which have pressure relieving members 41 which engage the housings 23, 24 and push them back so that the rollers 31 do not apply pressure to said flaps.

Title: Printing machines having control apparatus
IPC: B41L39/00
Filed: 1971-04-19
Abstract: 1345914 Printing apparatus MATHIAS BAUERLE GmbH 19 April 1971 [5 March 1970] 23443/71 Heading B6C A control device for sequentially operating the elements of a rotary offset lithographic printing machine comprises a shaft 1 carrying a series of control cams 2-8, a toothed switch wheel 27 fixed to the shaft and an actuating pawl 29 oscillatible in synchronism with the machine drive and arranged to be brought into engagement with the wheel 27 under the control of a solenoid 50. The teeth of the wheel 27 are profiled such that the pawl, when engaged with the wheel perform a predetermined number of control switching steps before becoming automatically disengaged. The cams 2-8 are arranged to control the main motor switch, the paper feed, the plate cylinder trip, the etching apparatus trip, the inking and damping apparatus trip and the blanket washing apparatus trip respectively. The functioning of each of these cams is brought about by a corresponding indexing movement of the wheel 27. A manually operable knob 15 is used to sequentially set all of the machine functions in operation. In response to the detection of a low paper supply at the feed board the solenoid 50 is actuated and a locking disc 23 is moved (by lever 48) to permit the pawl 29 (oscillated by a cam mounted on the shaft of the blanket cylinder) to engage the switch wheel 27 and index the wheel until the configuration of a tooth causes the pawl to rise sufficiently for the locking disc 23 to re-engage. At this stage the paper feed is stopped and the blanket cylinder is tripped out. After re-load of paper the mechanism may be manually re-set to print. In response to brief depression of a manual push button the solenoid is actuated to set the machine in the tripped condition discussed above. Further depression of the button causes tripping out of the inking apparatus after which the tooth profile causes the pawl to be again rendered inoperative. Further depression brings the machine to a condition where only the blanket washing apparatus is operative and after a predetermined number of washing cycles the solenoid is automatically operated to switch off the machine. After printing of a predetermined number of copies as determined by a sheet counter the solenoid is actuated to cause the machine to be set for the blanket wash condition and then to shut down. In an alternative embodiment, switching on of the various machine elements may be controlled by a further switch pawl.

Abstract: 1,060,088. Tubular films. BADISCHE ANILIN- & SODA-FABRIK A.G. June 9, 1964 [June 12, 1963], No. 23807/64. Heading B5B. Shrinkable films of thermoplastics which are cross-linkable by free radicals are produced by extruding a homogeneous mixture of a thermoplastic and a free radical-forming compound in the form of a ribbon under conditions under which no formation of free radicals occurs, heating the ribbon to 160-280 C. on a support so that the thermoplastic becomes cross-linked, pressing together the edges of the cross-linked thermoplastic at 180-280 C. in the presence of oxygen-containing gases to form a tube having a longitudinal weld, converting the tube into a tubular film having a thickness of 10- 1000 microns by inflation and simultaneous stretching in longitudinal direction at 50- 150 C., and cooling the tubular film under tension. The support on which the ribbon is cross-linked may be an endless belt of wire netting moving in the direction of extrusion at a speed at least as great as the speed of extrusion, heating being carried out by heat radiation. Alternatively the support may be a bath of liquid, e.g. glycerol heated to the cross-linking temperature, on which the ribbon floats. The ribbon is moved forward by recycling the liquid. After leaving such a crosslinking bath, the ribbon may be cooled by spraying with water. The edges of the film may be welded together by pressing the overlapped edges together with two streams of hot air. The air used may have had oxygen or nitrogen added. The tube may be inflated between two pairs of nip rolls, the gas required for inflation being passed into the tube from a capillary which passes with the welded ribbon through the pair of rolls nearest the welding means. The inflating gas may be heated. The film may also be heated during inflation by electrical radiators. Water sprays may be used to cool the film while under tension. Specified thermoplastics are polyethylene and copolymers of ethylene with propylene, butene-1, vinyl acetate or butyl acrylate. The freeradical forming substance may be an organic peroxide, several of which are specified.
