An apparatus for embossing substantially tubular workpieces comprising, a turret supporting a plurality of head assemblies for orbiting movement in an indexing manner about a central axis, a drive for indexing each head assembly to a plurality of station including an infeed station and an embossing station, an infeed for feeding a workpiece on each head assembly as said infeed station, means for holding a workpiece on each of said head assemblies in a substantially cantilevered manner, an embossing device at said embossing station, and means for moving each of said head assemblies so that its workpiece is brought into operative association with said embossing device to enable embossing thereof, each of said assemblies being indexed into position at said embossing station by said turret and said moving means comprising an actuator which engages each assembly as it is indexed into position and moves each assembly in a rectilinear path substantially parallel to said central axis thereby moving the associated can in position to enable said operative association, said embossing device embossing the entire workpiece area which is to be embossed in a substantially simultaneous manner with the workpiece held stationary.
Claim 40
Dependent Claim
64 words
An apparatus as set forth in claim 26 in which said embossing device comprises an automatic radially expandible and contractable female die assembly which is automatically expanded to receive each can therewithin and is automatically contracted around the sidewall of each can to enable embossing thereof and further comprising means instantaneously urging said sidewall radially outwardly against said die assembly to achieve said embossing.
Claim 41
Independent Claim
160 words
A method of shaping substantially tubular workpieces comprising the steps of, infeeding a plurality of workpieces on a plurality of head assemblies provided on a turret which is rotatable in an indexing manner about a central axis to a plurality of stations including a shaping station and an ejection station, holding each of said workpieces on its associated head assembly in a substantially cantilevered manner, indexing each of said head assemblies and its associated workpiece to a position adjacent and spaced from said shaping station by rotating said turret in said indexing manner, moving each assembly from its position adjacent said shaping station substantially parallel said central axis to move the associated workpiece into operative association with a shaping device at said shaping station, shaping each workpiece at said shaping station by shaping the entire area thereof which is to be shaped in a substantially simultaneous manner with the workpiece held stationary, and ejecting each workpiece at said ejection station.
Claim 42
Independent Claim
160 words
A method of shaping substantially tubular workpieces comprising the steps of, infeeding a plurality of workpieces on a plurality of head assemblies provided on a turret which is rotatable in an indexing manner about a central axis to a plurality of stations including a shaping station and an ejection station, holding each of said workpieces on its associated head assembly in a substantially cantilevered manner, indexing each of said head assemblies and its associated workpiece to a position adjacent and spaced from said shaping station by rotating said turret in said indexing manner, moving each assembly from its position adjacent said shaping station substantially parallel said central axis to move the associated workpiece into operative association with a shaping device at said shaping station, shaping each workpiece at said shaping station by shaping the entire area thereof which is to be shaped in a substantially simultaneous manner with the workpiece held stationary, and ejecting each workpiece at said ejection station.
Claim 43
Dependent Claim
54 words
A method as set forth in claim 28 in which said infeeding step comprises placing each of said workpieces on a cradle past which each head assembly is orbited, and positioning said cradle once a particular workpiece has been fed on a head assembly to enable said orbiting thereof without obstruction by said cradle.
Claim 44
Dependent Claim
51 words
A method as set forth in claim 28 in which said plurality of stations comprises a rotary positioning station and comprising the further step of rotary positioning said workpiece after indexing thereof to said rotary positioning station, said rotary positioning being achieved with each workpiece held firmly on its head assembly.
Claim 45
Dependent Claim
67 words
A method as set forth in claim 30 in which said rotary positioning step comprises rotating said workpiece to bring it up to a predetermined speed, energizing an associated photoelectric detector used to detect a registration mark on said workpiece, and stopping rotation of said rotating device and hence said workpiece following detection of said mark to thereby assure said workpiece is stopped at the desired position.
Claim 46
Dependent Claim
100 words
A method as set forth in claim 28 in which said plurality of workpieces comprises a plurality of cans each having a bottom wall, a sidewall, and an open end, said holding step comprises holding each can in said cantilevered manner by vacuum acting against its bottom wall, said moving step comprises the step of axially telescoping each can parallel to said central axis into said operative association, and said shaping step comprises the step of embossing the cylindrical sidewall of each can with an embossing device at said shaping station, said embossing being achieved in said substantially simultaneous manner.
Claim 47
Dependent Claim
74 words
A method as set forth in claim 32 in which said embossing step comprises the step of forcefully urging the sidewall of each can outwardly against automatically radially collapsible and expandible female die means comprising said embossing device to provide a desired embossed pattern thereon, said die means being automatically collapsed to enable the embossing action to take place and being automatically expanded to enable removal of the can from within said die means.
