Abstract
An apparatus for unwinding rolls of sheet material and for adhering the end of one roll to the beginning of the next at full running speed, without interruption. Means are also provided to permit operation with rolls of different widths and even with two narrow rolls alongside one another. A support which can be operatively positioned between two such narrow rolls can be moved laterally out of the way to take up an end-supporting position when a single wide roll is being unwound.
