Between the cloth rollers b, b<1> and bottom guiderollers c, c' in the trough d are arranged the cloth-expanding rollers a, a'. The rollers b, b<1> are driven alternately from a shaft f through bevel-wheels f<1>, h<1>, f<2>, k<1>. Clutches l, m on the shafts h, k of the rollers b, b<1> each have two clutch members, those on one side l<1>, m<1> serving to engage the wheels h<1>, k<1> to drive the shafts, and those on the other side l<2>, m<2> serving to engage the shaft with clutch members p<1>, q<1> at the sides of chain-wheels p, q respectively. The chain-wheels p, q connect by chains p<2>, q<2> with chain-wheels p<3>, q<3> on the shafts of the rollers a<1>, a. The arrangement is such that, when the roller b is being driven, its chain-wheel is free, and the roller b<1>, being pulled around by the cloth, drives its chain-wheel to turn the expanding-roller a against the cloth. Meanwhile the roller a<1> acts as a guide-roller. The driving of the expanding-rollers also reduces the braking action required for the non-driven cloth roller.
Patent GB-1034416-A (GB)
Title: Method of and apparatus for sterile packaging of sterile substances
IPC: B65B55/06
Filed: 1963-04-11
Abstract: 1,034,416. Packaging machine. ALPURA A.G. April 11, 1963 [April 12, 1962], No. 14606/63. Heading B8C. A method of sterile packaging of sterile substances comprises forming a tube from a packaging material, partly filling the tube with the substance to be packaged and compressing it transversely of its length to form sealed filled packages, the inside of the tube being sterilized by heat, the energy of which is transmitted through the wall of the tube from outside it. Packaging material 5 in the form of paper coated with plastics is drawn continuously into a ring 3 to form a tube 5b with the coated side inwards, the side edges being sealed by a heating pad 7. The tube is sealed transversely in known manner by pairs of heated jaws 10, 11, to form tetrahedral packages. The sterile substance, e.g. milk, is supplied to the apparatus by a pipe 21, the supply being controlled by a float 9 to ensure a constant level within the tube. The upper part of the tube is closed by a member 33 having a recess 38 to collect any condensed water on the filling pipe 21. A device 61 comprising a quartz annulus 62 containing heating coils 64 is arranged around the tube above the liquid level. Before the supply of sterile substance begins hot air is passed through the pipe 21 so that all the elements in the tube's interior are sterilized. The supply of hot air is stopped prior to the introduction of the sterile substance, the heat flowing through the walls of the tube sterilizing the inside wall before it comes into contact with the milk. In another embodiment (Fig. 3, not shown) the tube is heated by contact with a sterile fluid medium supplied to a jacket surrounding the tube and which may also be supplied to the inside. The sterile air or some other inert gas supplied to the interior of the tube need not be heated during the operation of the machine but serves to prevent atmospheric air entering the tube. To prevent damage to some packaging materials during the heating process, they may be passed through an anti-bacterial chemical solution so that the temperature required to kill the bacteria is lower than would otherwise be possible. Extra heating means may be provided in the interior of the tube.

Abstract: 1,149,603. Isotropic stretching apparatus. RHONE-POULENC S.A. 28 March, 1968 [31 March, 1967; 8 Dec., 1967], No. 15045/68. Heading B5B. Apparatus 1 for isotropically stretching a sheet of a plastics material comprises a plurality of screw-threaded rods 4 extending radially from a central member 2, a screw-threaded gripping means 9, 10 for the sheet mounted on each of the rods, the threads on the rods cooperating with those on the gripping means, the gripping means being disposed relative to one another in an array of particular and regular configuration and gearing 15 interconnecting the rods whereby rotation of one of the rods as at 16 will cause rotation of all of them so that the gripping means move along their respective rods at such a rate as to maintain the configuration constant. Preferably there are at least five gripping means, and bevel gearing is used. The rods may each have a bevel gear on their inner ends which (a) cooperates with a central bevel gear (Figs. 1 and 2, not shown), (b) co-operates with the bevel gear on the ends of adjacent rods, in which case the thread of adjacent rods is of opposite pitch, as shown in Fig. 6, or (c) co-operates as in (6) but through an idler gear on each side. The configuration may be circular, rectangular, or elliptical; in these latter cases the pitch of the threads on adjacent rods is varied so that the configuration is maintained as the grippers move along the rods (Fig. 4, not shown). Preferably the apparatus lies in a flat plane; alternatively the clamping devices may be arranged along concurrent axes which form the generatrices of a cone. The examples show the stretching of polyethylene terephthalate in the form of circular sheets, which may subsequently be subjected to heat-setting.
