Hollow-ware. - An automatic machine for bending zinc cylinders for galvanic cells comprises three driven rolls one of which is raised and lowered from or towards the lower pair of rolls so as to permit the metal strip to be guided across the lower rolls and cut off during the rising motion and the rotation of the rolls to be started and the strip bent during the lowering motion. The strip 13 is fed across the rolls 5 against a stop 14 by a slide 12 through a weight 49, the stop being raised from the rolls 5 by a camoperated rod 17 during bending so as to prevent dirt dropping on the rolls. A length is cut off by a knife 16 on a cam-operated lever 15 cooperating with a fixed cutting edge 55, a spring-pressed ledge 32 being forced up when the cutter is raised so as to lift up the end of the succeeding strip which is held down during the bending operation. The roll 6 is raised and lowered by a cam-operated lever 7 and when raised is embraced by an ejector 23, which is pivoted at 31 and is set against the action of a spring 30 by a lever 21 operated by the cutter during the down stroke, the ejector being held by a lug 24 engaging a spring-pressed pawl 25. When the cutter is raised a rod 27 thereon engages the stop 28 so as to free the ejector which is operated by the spring 30 to eject the formed cylinder. The cam shaft 53 is driven through a pin coupling 54 by a chain and spur gear 51, 9 from a pulley 2 which is loose on the shaft 1 and is connected thereto by a clutch 3 operated by a cam 60, levers 19, 4 and rod 20 to rotate the rolls during bending. The pin coupling is normally disengaged by a lever 45 mounted on a spring-controlled shaft 43, which is operated by a hand lever 40 through a rod 41 and arm 42 so as to remove the lever and allow the cam shaft to be rotated. The hand lever is held in position by a spring-pressed trigger 37. When the strip is exhausted an adjustable pin 35 on the slide 12 engages a lever 34 so as to withdraw the trigger and reset the hand lever so as to disengage the pin coupling and thus stop the machine. The hand lever has a hook 46 to which may be connected by a chain or rope a treadle or a hand-lever at the other end of the feed path.
