ABSTRACT:
The disclosure includes method and apparatus for handling elongated webs of sheet metal, and a sheet metal construct formed as an intermediate product and comprising a parent coil pre-divided into a plurality of daughter coils. In one method sequence, separation can be completed by the end user of the coil just before it is fed into a press or the like. In another method sequence, separation is completed during wrapping of the parent coil. In still other sequences, completion of separation can be accomplished at stages intermediate these two. Slitting may be done directly off a mill. Edge trim strip may be wound as part of the parent coil to simplify scrap handling, and may be used to protect the coil in transit.
