ABSTRACT:
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.
