Abstract
Abstract In affixing a tape to an adhesion form by pressing the tape thereagainst with a press roller at the forward end of a tape supply head rotatable about a C axis while feeding the tape to the press roller, a method comprising detecting the positions of opposite side edges of the tape during the tape affixing operation with sensors on at least one of the front and rear sides of the press roller, calculating the amount of sidewise deviation of the tape from the resulting detection signals, calculating the required angle of rotation of the press roller about the C axis based on the calculated value, and rotating the press roller about the C axis by an amount corresponding to the amount of sidewise deviation of the tape in a direction opposite to the direction of sidewise deviation of the tape to thereby current the deviation and maintain the amount of sidewise deviation within a very small range. An apparatus for practicing the method is also disclosed.
