Abstract
A method for producing continuous feed of strip from finite lengths includes producing coils by locating strip at a predetermined point along its length, in the gap between two segments of a mandrel and rotating the mandrel so that the strip feeds from two directions for coiling.
Claims10
A method for producing continuous feed of strip from finite lengths comprising producing a plurality of coils by winding each strip on to a mandrel having at least two portions separated by a gap between which the strip is located and completing a series of cycles, each cycle comprising unwinding one of said coils to feed the head thereof into apparatus requiring said continuous feed and to feed the tail-end thereof to a fixed station whilst storing the balance of the tail end of said coil in a first accumulator, and unwinding another of said coils to feed the head thereof to the fixed station for attachment to the tail end of said one coil whereby to maintain a continuous feed;
- the tail end of said other coil subsequently being fed to said fixed station whilst the balance of its tail end is stored in a second accumulator.
Apparatus for producing continuous feed of strip from finite lengths comprising a first and a second uncoiling station for uncoiling coil produced from strip wound on to a mandrel having two portions separated by a gap between which the strip may be located for coiling, a strip accumulator adjacent each of the uncoiling stations and disposed between them to receive strip unwound from the coils together with a station intermediate the accumulators for securing the head of one coil to the tail of the other coil.
