Abstract
The leading end of a web on a roll of web convolutions is prepared for a splice by releasably securing that web end to the adjacent underlying web convolution on the roll and then adhering to that convolution just ahead of the web end a spoiler strip having a lengthwise boundary line which extends the length of the strip. A surface portion of the strip on one side of that boundary line is coated with an adhesive so that the adherent portion of the strip is speed in front of and substantially parallel to the web end whereby when the roll is rotated, the spoiler strip deflects the on-coming air stream away from the web end, yet permits the web end to be pulled away from the roll when being spliced to another web. Different spoiler strip constructions are also disclosed.
