Apparatus is provided for trimming the open end of a seamless cup-shaped metal can body. The apparatus includes a plurality of spindle units receiving and supporting can bodies to be trimmed for movement along an arcuate path. The spindle units cooperate to axially position the can bodies relative to a fixed cutting blade positioned along the path and past which the can bodies are moved. During movement of the spindle units along the path and between input and output stations of the apparatus, can bodies supported thereby are rotated about the corresponding spindle axis. As each can body moves past the fixed cutting blade it is rotated one complete revolution to sever an annular scrap ring from the open end thereof. Thereafter, the trimmed can and scrap ring are displaced from the spindle unit and discharged from the apparatus.
Apparatus for edge trimming the open end of a cup-shaped metal can body comprising, a frame, can body supporting spindle means having a spindle axis, means for supporting and moving said spindle means and a can body supported thereby along an arcuate path relative to said frame, said arcuate path having a second axis radially spaced from and parallel to said spindle axis, cutter means supported by said frame at a location along said path, and means to rotate said spindle means and said can body supported thereby about said spindle axis during movement of said spindle means and can body about said second axis and past said cutter means, said cutter means being positioned on said frame to sever an axial portion from the open end of said rotating can body moving therepast.
Apparatus for edge trimming the open end of a cup-shaped metal can body comprising, a frame, a drive shaft supported by said frame for rotation about a shaft axis, a plurality of can body supporting spindle units having corresponding spindle axes parallel to and circumferentially spaced apart about said shaft axis, means mounting said spindle units on said drive shaft for rotation therewith, each said spindle units including axially opposed first and second can body clamping spindles, said mounting means including means supporting each said first and second clamping spindles for axial reciprocation between corresponding extended and retracted positions and said first clamping spindle for rotation about said spindle axis, means for rotating said first clamping spindles about the corresponding spindle axis during rotation of said spindle units about said shaft axis, means to reciprocate said first and second clamping spindles between the extended and retracted positions thereof during rotation of said spindle units about said shaft axis, each said spindle units moving a can body supported thereby along an arcuate path relative to said frame and simultaneously rotating said can body about the corresponding spindle axis, cutter means including a cutter blade on said frame having a cutting edge extending along said path and positioned to sever an axial portion from the open end of a rotating can body moving along said path, means to rotate said drive shaft, means to feed can bodies to be trimmed sequentially to said spindle units, means to discharge trimmed can bodies from said spindle units, and means to discharge said severed axial portion of said can body from said spindle units.
