An ultrasonic sealing and cutting machine 20 comprises a transducer 23, preferably of the magnetostrictive type, connected to a generator (not shown) and which ultrasonically vibrates a tool 24 formed with a tungsten carbide disc 25 to contact the sheets to be sealed. A carriage 31 for the anvil 46 is slidably mounted on rods 26, (27), the latter not shown, and is formed with an undercarriage 32 connected, through a resilient coupling 33, a rod 34 and a crank 36, to a lever 35 manually operable to allow the insertion of the sheet edges to be sealed between the tool 24 and the anvil 46. The movement of the carriage 31 towards the tool 24 is limited by a post 43 on the carriage 31 engaging an adjustable shaft 42 on a micrometer head 41. The anvil 46 is of generally circular section, is formed with outwardly projecting flanges 48, 49 and is secured to the carriage 31 by a screw 47. The tool 24 co-operates with the flange 48 and when one portion of the periphery of this flange is worn the anvil is rotated, after loosening of the screw 47. When the entire flange 48 is worn, the screw 47 is removed and the anvil 46 is inverted so that the flange 49 co-operates with the tool 24. The anvil 46 may be made of Portland cement having asbestos fibres therein in the form of staple fibres or a woven fabric. Alternatively, the anvil 46 may be a layered carbon cloth material bonded together with carbon. The machine may be used to seal the overlapping ends of a polyvinyl chloride shrink film wrapper which has been wrapped about a bottle containing a pharmaceutical product and to simultaneously cut off any excess film material.

A quantity dependent on the longitudinal stress in material passing between one pair of rolls is stored and compared with a later value of the quantity when the material is passing between two pairs of rolls, any deviation from a desired comparison being effective to control the drive of one of the roll pairs to restore the desired comparison. In Fig. 1, successive pairs of mill rolls 11, 12 are driven by electric motors 18, 19 supplied from Ward-Leonard or thyristor controllers 20, 21. The speed of drive is stabilised by tachometer generators 29, 30, controlling through amplifiers 31, 31, current feedback systems associated with motors 20, 21. When, initially, the start of the material reaches a photo-cell 16, the latter causes a switch 24 to open momentarily to apply to a digital store 22 a signal representative of the current of motor 18 which then corresponds to zero tension. Thereafter the stored signal is continuously compared at 27 with the instantaneous value of the current of motor 18 so that when the start of the material reaches a photo-cell 17, indicating that both sets of rolls engage the material, a switch 26 closes so that any changes in tension from a desired value, e.g. zero, are effective through an amplifier 33 to control the datum of the speed control system associated with motor 19 to restore the desired tension. Switch 26 re-opens when the end of the material passes a photo-cell 14 in readiness for control of the next piece. Control of hot or cold rolling, forward or reverse rolling, a plurality of roll sets, and thickness, are referred to.
