Title: Automatic towel processing and supplying machine
IPC: A47K10/32
Filed: 1964-02-25
Abstract: 1,032,151. Wrapping-machines; wrapped towels. T. MATSUI. Feb. 25, 1964 [April 21. 1963; June 13, 1963 (2); July 5, 1963], No, 7791/64. Heading B8C. [Also in Divisions B5, B6 and G4] In a machine which dispenses pieces of towel cut from a length, one piece being dispensed for each actuation of a control button (or insertion of a coin if the machine is coin freed), each piece is rolled and wrapped in polyethylene film. As seen in Fig. 2, an endless band conveyer 73 takes a severed piece of towel which lies in suspense beneath a sterilizing lamp 75, passes the piece beneath spray nozzles for wetting with hot or cold water if this is desired, and is then rolled into a cylinder by the overlying endless band 81 into which it is wedged. When completely rolled the towel is carried beyond the end of conveyer 73, the band 81 being lifted out of the way by a cam 83. Actuation of cam 83 actuates a switch 85 to release compressed air from a bottle 87 to produce a perfume spray from bottle 89. The rolled towel passes through this spray as it precipitates into the waiting jaws 100 and 108 of a wrapping device. As best seen in Fig. 11, the wrapping device has a drum 91 of foil 27 which is delivered by rollers 98 and 99 to hang in a loop in the jaws 100 and 108. With the roll of towel received the jaws close as shown in Fig. 13 to sever the foil with cutters 115 and 117 and to seam the ends of the foil together by pressing them between a rubber bar 118 and a heated bar 103. When the jaw 108 drops, the wrapped towel is ejected by a roller 120 mounted on the fixed jaw 100 as shown in Fig. 14. The wrapping foil may be fed from the side as shown in Fig. 15, the foil being bent into a channel section as it is propelled up a guideway 96a. Seaming takes place as before but the cutters are placed at the side of the jaws. Instead of cranking the jaw 108 through a rotating arm and linkage 112 to 114 as shown in Fig. 11, the jaw is swung by the cam 235 in the arrangement of Fig. 15. Instead of driving the rolled towel off the end of the conveyer 73, the conveyer can be tilted downwardly to precipitate the roll into the jaws of the wrapping device. If the supply of foil runs out a limit switch 93-95 stops the machine.

Title: Eccentricity correction means
IPC: B21B37/66
Filed: 1972-02-21
Abstract: 1425826 Rolling mills DAVY-LOEWY Ltd 14 May 1973 [21 Feb 1972] 7831/72 Heading B3M [Also in Division C3] During operation of a rolling mill measurements representative of eccentricity of the work rolls (or of the backing rolls if these are present) are made and are applied to a plurality of electrical stores, the outputs of the stores subsequently being fed, in synchronism with the work rolls (or the backing rolls), to apparatus for adjusting the roll gap, in a sense to compensate for the eccentricity. In a two-high mill, Fig. 1, or a four-high mill in which the backing rolls rotate in synchronism, the works rolls are rotated in contact and provide a pressure output signal at 5 representative of roll eccentricity. The signal is fed by a switch 6 successively to stores 7 (of which there may be sixteen). During subsequent rolling, the outputs of the stores are successively connected by a switch 8, which operates in synchronism with the rolls, to a roll gap adjuster 4. In a four-high mill in which the backing rolls do not rotate in synchronism, Fig. 2, a signal representing the eccentricity of all the rolls is provided by a workpiece thickness gauge 13 located downstream of the mill. The signal is fed through a time delay unit 14 to stores 16 and is subsequently fed to the roll gap adjuster 19. The period of delay corresponds to a whole number of revolutions of the backing rolls. The adjuster 19 is also fed with an error signal corresponding to any difference between a reference roll gap and the actual gap. The adjuster 19 in the arrangement of Fig. 1 can also be provided with an error signal relating to the roll gap. A combination arrangement, in which both pressure differences during initial rotation of the work rolls is measured and gauge variations in the roll workpiece are measured, may be employed.

Class 20(4) A water-tight covering for a structure 1 which is liable to crack, e.g. at 1, comprises an outer film of waterproof and elastic material 2, e.g. of polyvinyl aceto-chloride, which is insulated from the structure 1 by a thin intermediate layer 3, e.g. of polyvinyl acetate, the latter having a lesser degree of longitudinal elasticity than the material 2 so that it can slip when the crack 1 ocurrs and distribute a localized deformation over a zone L of the water-proof layer 2 of greater width than that of the crack 1. If the limit of elasticity of the polyvinyl aceto-chloride is not exceeded the layer 2 will return to its original length, without wrinkling, when the crack l closes. The intermediate layer 3 can be applied either by dusting polyvinyl acetate, or by brushing a solution of polyvinyl acetate, on to the structure 1 and then covering it by a dusting, or a brushing of a layer of polyvinyl aceto - chloride. In a modification a roughened layer of polyethylene is laid by machinery on a plastic intermediate layer of polyvinyl acetate, a protective covering of plastic material, e.g. a solution of plasticized and stabilized vinyl copolymers having approximately the same elasticity as the layer of polyethylene, being applied over the latter. In a further modification, Fig. 5, the intermediate layer consists of Kraft paper 6 which is stuck by its underface 7 to the structure 1, the polyethylene layer 4 being stuck on to the ends of fibres 8 which fill the roughened face of the Kraft paper 6. The core of the Kraft paper will tear over a crack 1 so that a pull will be exerted uniformly over a zone L of the layer 4. In this embodiment the Kraft paper 6 will preferably be stuck to the structure by means of an adhesive of anti-capillary nature in order to prevent rise of water from the structure.
