Abstract
A package of a continuous strip of material comprises a plurality of parallel side by side stacks each containing a length of the strip which is folded back and forth such that each folded portion of the stack is folded relative to the next portion about a line transverse to the strip and such that the side edges of the strip portions are aligned. The strip is continuous through each stack and is connected by a splice from the end of one stack to beginning of the next stack. The package is compressed to reduce the height of the stacks and maintained in the compressed condition by an evacuated sealed bag. The preferred package arrangement uses the package for pay off of the strip in an orientation in which the stacks are horizontal The spliced connection portions are flat against opposed sides of the package. Alternate stacks are reversed in orientation so that the strip of one stack is connected to the next through the splice portion in a manner which ensures that the same surfaces of the strips are connected through the package. The reversing is effected by twisting the strip before folding.
