摘要 A pad forming process forms a stack of sheets, each sheet bearing adhesive on at least a portion of one side thereof. A sheet cutting die is provided having sheet collection cavity therein. A web comprising a linerless elongated sheeting having one side at least partially covered with an adhesive is advanced past the die. The die cuts the web to form a first cut sheet which is retained within the sheet collection cavity of the die. The web continues to advance past the die.
