ABSTRACT:
The winding of tubes of substantially uniform diameter from sheet stock which varies in thickness comprises slitting the stock along one edge as it is unwound from a supply roll to form a web of predetermined width and subsequently cutting the web transversely to form successive blanks of predetermined length and width which are wound upon themselves from one side to the other to form convolutely wound tubes. Should the diameter of the tubes vary due to an increase or decrease in the thickness of the sheet stock, the width of the web is varied inversely with changes in the thickness of the stock.
