| A method for trimming salvage edges from container ends by axially inserting a cutter into the open end of a container surrounded by a backing member, shifting the cutter transversely of the longitudinal axis of the container and producing relative rotation between the cutter and container to trim salvage edges from the inside to the outside of the container. The apparatus for trimming salvage edges includes an elongated member rotated about an axis and having a plurality of circumferentially spaced trimming stations. Each of the trimming stations includes a fixed backing member having an opening, a container support movable between first and second positions on one side of the backing member, and a cutter supported eccentrically of a shaft on the opposite side of the backing member with the shaft being movable transversely and axially to temporarily align the cutter with the axis of the opening, and position the cutter inside the container in engagement with the container wall so that rotation of the shaft will trim the salvage edge. The cutter is designed to automatically produce an arcuate surface on the inner edge of the container wall during the cutting operation. Camming members cooperate with the shaft and the container support to move the shaft and container support to the various positions during each cycle of rotation of the elongated member.

| Apparatus for simultaneously changing all of the tools in a multiple spindle machining center is provided with a number of tool carrying devices, each device corresponding to a different one of the spindles. Each tool carrying device is capable of selectively engaging each of a number of tools which are dedicated for use with one of the spindles, and is further capable of carrying engaged tools between one of the spindles and one of a plurality of tool storage magazines. A first linear translation device moves each of the tool carrying devices in parallel relationship with a first axis when the tool carrying devices are carrying tools between the spindles and the magazines, and a second linear translation device moves the tool carrying devices in parallel relationship with a second axis during such tool carrying operations, the first and second axes being in orthogonal relationship. The tool carrying devices are mounted upon a single rigid bar, the axis of the bar being orthogonal to both the first and second axis.
