    摘要: A package of a strip of material is formed by slitting or perforating a web to separate the web into side by side strips and fan folding the web to form a plurality of side by side stacks of the strips. The strip of each stack is spliced to the strip of the next stack to form a continuous strip through the package which can be unfolded for supply continuously to an end use machine. The package while compressed is wrapped by a packaging material which includes a bottom header plate and heat shrink bag wrapped around the package and under a bottom header plate and heat sealed to a bottom surface of the bottom header plate. The spliced connecting portions are held attached to the end plane of the package by a series of spaced tie members formed of spare strip material each of which extends across the end plane and has opposed ends of the tie member tucked between two of the strip portions of respective ones of the outermost stacks. Downstream of the supply and prior to folding a splice detector is responsive to the presence of a supply splice in the web and the control of the process is arranged to mark for rejection any package wherein the number of detected supply splices contained therein is greater than a predetermined number. The strip portions are spliced by ultrasonically heating the strip portions while in contact preferably at a butt splice while using heat sealable bridging fibers to effect a heat seal between the portions.
